Effect Description ViPER FX

TRANSLATION OF EFFECT DESCRIPTIONShttp://vipersaudio.com/blog/?page_id=43

*** Quick Reference ***

"Install driver" - install / update ViPER4Android effects driver.

"Remove driver" - remove ViPER4Android effects driver.

"Compatibility" - set compatibility mode.
“No” - make ViPER4Android a global effect.
"Enable" - make ViPER4Android local effect.


***Questions and answers***

Q: Do V4A effects work in all or most media players?
A: Try to turn on compatibility mode, restart the device and check again.

W .: how to switch sound quality?
A: Delete the driver using the menu command, restart the device and select the desired level of sound quality.

W .: how to reduce power consumption?
A: When compatibility is disabled, the rejection of touch and unlock sounds can extend battery life 4 times; Use the "Energy Saving" driver.

W .: How to set up V4A and PowerAmp?
A .: if V4A will be used in other programs (online radio, video players, etc.), then PowerAmp needs to disable Direct Volume Control (DVC), disable Compatibility in V4A and reboot the device.
If V4A will be used only with PowerAmp, in V4A you need to enable "Compatibility", in PowerAmp - "Support FX" (FX means "effects"), then the DVC function will be able to work.

Q: What is “Effect Fixation”?
Рћ .: the settings of the selected tab are applied to all outputs (headphones, speaker, bluetooth, usb).


Forum:http: //forum.xda-devel...owthread.php? t = 2191223


ATTENTION:
continuous listening for more than 1-2 hours per day is not recommended, for in-ear headphones time is halved. Possible delayed hearing problems with excessive loudness, as well as complete irretrievable loss of hearing due to excessive sound pressure when using in-ear headphones.
With a symptom of tinnitus, it is recommended to revise the settings used, the volume level, the headphone model in the direction of a lesser load on the ear.


*** Drivers ***

"High quality" - 64-bit floating point processing, 127th order equalizer with finite impulse response (for ARM CPU with NEON extension).

"Standard quality" - 28-bit fixed-point processing, an equalizer with a non-linear phase (for ARM CPU with NEON extension; similar in performance for x86 CPU).

"Energy Saving" - 24-bit fixed-point processing, equalizer with non-linear phase (for ARM CPU with NEON extension; default for ARM CPU with and without VFP extension).


*** Effects ***

*Headphones*

1. "All effects". The setting is responsible for turning on the music effects for headphones.

2. "Auto gain control", "AGC". The main purpose - the dynamic increase or decrease in sound volume.

2.1 "Level" - the rate of increase or decrease, and the higher it is - "Maximum", the faster the increase and the higher the level of the final volume. At the "Minimum" level, the final volume increases more slowly, its level will be closer to the original volume. Recommended "Medium" level.

2.2 Maximum Gain - Limit. If the recording level of a song is too low, you can set higher values ​​to enhance the sound. The higher the value, the higher the volume. Too much gain will also make the noise in the composition noticeable. Recommended "4x".

2.3 Maximum level - "Threshold". Specifies the maximum volume in dB that “Auto Gain Control” can achieve. The higher value corresponds to the increased volume, "0 dB" is the maximum level. "-1.9 dB" is recommended to soften the sound.

3. "Digital correction" - playback correction for a specific device model. Beyerdynamic T1 is used as a reference. Manages the frequency response, transient response, phase delay, etc. For correct operation, you must have a device in the database, the device will be added in future versions.

4. "Spread spectrum" - expansion of the spectrum lost during compression. When playing lossy formats (MP3, AAC, OGG), the sound can be close to the lossless formats. Disable when playing uncompressed formats.

5. "Equalizer". Ten-band linear equalizer, n-th order (determined by the driver).

5.1 "Presets". You can choose one of the preset equalizer settings. If “Manual” is selected, the sound will correspond to the position of the knobs set by the user.

5.2 Linear graphic equalizer. If you touch the graph, in the pop-up window you can adjust the levels of amplification and suppression of frequencies in 10 bands.

6. "Convolver". If the impulse response pattern “Impulse” is loaded, the sound will be processed similarly to the conditions under which the impulse was recorded. If various effects were used to create a pulse, they will also affect the sound along with the room acoustics and the sound features of the reproducing apparatus, the characteristics of which transmit the impulse response.
Make sure that the memory card has a folder ViPER4Android / Kernel /, impulses should be placed in it. If the folder does not exist, when saving the settings profile it is created automatically.

6.1 "Impulse". The list displays the pulses that are in the ViPER4Android / Kernel / folder.

6.2 "Channel crossing" - the interpenetration of channels. Places a sound in front of you.

7. "Spatial sound". Mainly used to create an enhanced sound effect. The sound can be stereo or monaural.

7.1 "Size of space". This value determines the intensity of the effect. The larger value corresponds to the increased stereo effect. The sound will be heard in the distance to the left and to the right.

7.2 "Center density" image. This value determines the density of sound in the middle of an imaginary scene. For larger values, the sound of the instruments seems close together and located in the center of the stage, with smaller sounds, it becomes distant and shifted to its edges.

8. Differential surround sound, known as the “Haas Effect”.

8.1 "Channel Delay". This value determines the delay (interval) between the left and right channels. More value - wider sound. The bias of the stereo panorama is imaginary and is due to the psychoacoustic features of the hearing, the effect is more relevant for monophonic recordings.

9. "Surround sound in headphones." Virtual surround sound effect for headphones. Designed to recreate the localization of sound sources in the room with the help of complex signal processing.

9.1 Hall Size - defines the size of the virtual room.

10. "Reverberation". Uses a mathematical method to simulate the feeling of the surrounding space. For example, a composition may sound like a performance in a hall, living room, bathroom, etc.

10.1 "The area of ​​the hall." This value determines the size of the virtual room. When magnified, the sound becomes wider and more echoes appear.

10.2 "Scene Width". This value sets the width of the above virtual space in meters. If we take the hall area as 100 m², set the stage width as 14 m, the hall length will be 7.14 m. Thus, the area of ​​the hall and the width of the stage determine the proportions of the virtual room. If you increase the value, the sound coming from both sides will be felt more clearly.

10.3 "Fading". This value determines the humidity of the air in the virtual room - moisture easily absorbs all the echoes. More value - less audible echo.

10.4 "Reflected Signal". This value determines the level of reverberant sound, taking into account the humidity and size of the virtual room.

10.5 "Direct Signal". This value determines the level of the original sound.
To simulate rooms with low air humidity, such as a living room, a hall and other closed spaces, you can use the hall area and the width of the stage to set the size of the virtual room, the air humidity is selected within 0 ... 20 percent, the level of the reverberated signal is 20 ... 50 percent, The level of the original signal is about 50 percent.
To simulate rooms with high humidity, such as a bathroom and other closed spaces with high humidity, air humidity is selected within 50 ... 100 percent, the level of the reverberated signal is 40 ... 80 percent, the level of the original signal is about 50 percent.

11. "Dynamic processing" is responsible for the dynamic range of sound. In other words, for the lower and upper frequencies, as well as limiting the signal level.

11.1 "Headphones". The value describes the type of headphones connected. If you cannot select a suitable device for rich bass, select "Regular headphones". Ordinary headphones are selected generically. Recommended "Ordinary headphones."

11.2 "Level LF". The value determines the average level of low frequencies, the larger value increases their intensity. Recommended "33 percent."

11.3 Lamp simulation - model "6N1J". This setting is responsible for enabling the lamp sound simulation. V4A uses a simplified mathematical model of tube sound simulation. When you turn on the effect, a large number of random high-frequency harmonic distortion is added to the sound and the number of odd harmonics increases.

12. Sound quality control - "Restoration of sound". Replaces XHiFi Sound Recovery technology. Manages the bottom - "Restoration LF", as well as the tops - "Restoration HF."

12.1 "Algorithm" restoration LF. "Natural", "Purified" and "Subwoofer" are available. “Natural” is the same as XHiFi’s Lo Contour V4A. "Purified" - gives the bottom of the purity. "Subwoofer" - makes the bottoms very powerful.

12.2 Low Frequency - "Frequency". Sets the bass frequency. Recommended "60 Hz" for all algorithms.

12.3 Bass Boost - "Boost." Responsible for the bass volume. Recommended "6 dB" for "Natural", "8 dB" for "Cleared".

12.4 "Restoration of HF" - the effect of a distinct sound.

12.5 Algorithm to improve the clarity of sound - "Algorithm". The algorithms "Natural", "OZone +" and "XHiFi" carry out a different increase in the clarity of sound. Ozone + performs simple RF processing. XHiFi is the same as XHiFi’s Hi Clarity V4A.

12.6 "Level". The intensity of the work of the restoration of high frequency. 3.5 dB recommended for Natural, 8 dB for Ozone +, Default for XHiFi.

13. "Crossfader". Reduces fatigue with prolonged listening, experimental function.

13.1 "Binaural level". The intensity of the effect. Recommended "Medium" level.

14. "Output signal". Gain, balance, and V4A output level limiting are available. Limiter is used to prevent distortion caused by overload, in turn creating distortion caused by clipping.

14.1 "Gain." The value controls the overall output volume.

14.2 Channel Panning, or stereo balance - "Balance". Determines the ratio of the left and right channels in the output signal.

14.3 "Limiter". Defines the limits of the amplitude limit of sound vibrations by the limiter, the maximum value of "0 dB".
The smaller the value, the easier it is to reach the limitation of the amplitude of the sound, which will lead to loss of sound detail due to clipping, but will help to effectively manage the final output volume. Recommended "0 dB".


* Phone speaker *

1. The main switch - "All effects". Allows you to enable V4A effects for the speaker.

2. Optimization of the dynamics. Optimizes the sound of the built-in speaker.

3. "Supergromkost". It enhances sound, but reasonably, to prevent damage to the speaker. Do not overload the speaker.

3.1 The intensity of the effect - "Level". Determines the speed of amplification or suppression, at a higher value, the speed increases and the final volume increases, at a lower value, the speed slows down, the final volume approaches the original volume. Recommended "Medium" level.

3.2 Maximum Gain - "Limit". If the recording level of a song is too low, you can set higher values ​​to enhance the sound. The higher the value, the higher the volume. Recommended "∞".

3.3 Maximum level - "Threshold". Determines the maximum sound volume in dB, higher value corresponds to increased volume, 0 dB is the maximum level. Recommended "0 dB".

oddly enough it sounds, but the effects of a lamp or band harmonics are just as little as a matter of fact band distortion and detonation (unstable frequency response). and even more, limitation in comparison with a number! ..- but this does not mean that it is not a beneficial influence on the specificity of these audio systems, as they say in taste and color, since it is subtracted from the provided articlegavsgovenkoI realized that even our ears are essentially frequency compressors, and not just a complex organ, designed to perceive sound vibrations ..
Sorry I will quote part of the article, as I consider this detail to be one of the most important since music and sounds are an integral part of our life and listening to music in headphones:
If the sound signals are given through headphones, then the auricles are pressed to the head. Since such a situation for the brain processor is unnatural, a person loses the ability to produce localization in space, placing the sound source as if inside the head. This property is called lateralization and causes significant fatigue of people who work in headphones for a long time. Currently, digital processors have been created that pre-filter the signals in the headphones, similar to the auricle. This makes it possible to “carry out” the sound image from the head, facilitating the work of sound engineers, operators, etc.- Do not forget this detail when setting up Vipera (which I tried to do in my own setup)
but I would also like to add that if the sound is too difficult to perceive (spreading out frequency, excessive volume) the source of the sound (localize), this will also lead to fatigue ..
In the range of 0-120 Hz are located only a kick and a bass.
In the 120Hz-8kHz range, all instruments are located. In the main (most part) in this frequency range are musical instruments: guitars, synthesized parts (Lida, Strings), piano, etc. But besides them, in this frequency range there are other mid-frequency components of the instruments: the middle frequencies of the drum and bass, as well as the average frequencies of the plates and percussion.
In the range of 8-22 kHz, the high-frequency components of all the composition tools are located. In the main (most part) in this frequency range occupy: plates, percussion, etc. But besides them, in this frequency range there are high frequencies of all the instruments of the composition.

here, be surprised:
Super Duper .
The most interesting thing is that SGS3, coupled with a viper, sounds almost also in headphones, and on my simple SVEN.
so, why .....
and escho, on the viper, you can easily adjust the sound like on vinyl (I heard a lot of it, I remember this sound ...), it would not be bad for the most obduenny audyphils (like me :)), add a crackle record (such as this)
when I chose smart, I didn’t bother with audio, because I was sure that there were no good audio devices on the robot, but when I heard SGS 3 I was surprised at first even with the sound performance.
just recently found out that 24-bit wolfson audio chip from surprise is replaced by understanding, but this viper lifted the sound to a whole new level, but I don’t understand how to play the phone better than my computer nehily audio card, and equal to the best audiophile devices?rhetorical question ...

Processing is processing, and the number of "processor" parameters in the wiper is so modest so far that, in my opinion, the "processor" would sound too pathetic.

Not at all pathetic, the processing of the wiper is quite solid in its capabilities.

ManТ‘[email protected], 19:58

Briefly about why I defended my version of Compander and disagreed with my colleagues: this sound processor can exist in digital audio processing, it is really able to limit the signal peaks and raise its level if the signal is below some values.

Compander is able to exist in analog sound processing, moreover: it was there that it existed. No digital processors were close and the compander was used as a squelch in analog tape decks. And maybe in the reel, now I do not remember exactly. Conventional analog circuitry, whose functions, along with others, today perform in digital. By the way, here we are not talking about limiting or raising the signal level: the compressor and the expander compress and stretchdynamic range i.e. the difference between the quietest and loudest signal levels. In analog technology, the loudest level was the maximum allowable for a given nonlinear distortion coefficient, and the quietest level was determined by the noise level. The compander first compressed the dynamic range during recording, then restored (expanded) during playback, and the noise level of the magnetic tape decreased. By the way, when the expansion function is strictly inverse to the compression function, no distortions are introduced by these processes (in the ideal case).
In the wiper, I suppose, the dynamic system controls the boost of the high and low frequencies depending on the volume set, the spectral content of the content and probably the dynamic characteristics of the headphones. Such a venture also requires manipulation of dynamic ranges, but this is not a compander in the traditional sense.

Guys, I’m interested in this question: is the term Q-Factor applicable (as I understand it is the attenuation level, or rather the time of a certain frequency variation, in fact, its width) for headphones, I think yes ... and it seems to me that the sample carries, besides the frequency response of the system, the quality factor of the circuit to some extent ..
Correct if I'm wrong please ...

Goodness- the parameter of the oscillating system that determinesresonance widthand characterizing how many times the energy reserves in the system are greater than the energy losses in one oscillation period.
The quality factor is inversely proportional to the damping rate of the natural oscillations in the system. That is, the higher the quality factor of the oscillatory system, the lower the energy loss during each period and the slower the oscillations decay.

If a sample is taken from a headphone, speaker, or other resonant system, then its quality factor is also transmitted essno.

But not applicable: the good quality describes the nature of the resonance. Cymbals naturally resonate, but their quality is regulated by the manufacturer of this wonderful musical instrument, but you cannot influence this characteristic :)

As I understand it, the concept of "dynamic bass" is the increase in those same harmonics of frequencies responsible for bass, a peculiar treatment of the bass expander?


It is interesting that the "main" (base) frequency range of musical instruments is quite low ...
based on the schedule:
0 - 16 Hz Infrastructure
16-70 Hz Bass
100-120 HzMidbas (medium bass)
500 Hz - 1 kHz Low frequency
4.5-5 kHz Mids
5-10 kHz Medium Frequency
10 - 20 kHz High Frequency ("top")
16 - 22 kHz Ultrasound

and from the article that I laid out above on the equalizer, most of the instruments in their “basis” are produced, they emit a low-frequency sound, with a limit for mid frequencies
Therefore, Low Frequencies (20-150 Hz) substantially complement the sound picture, make it richer and richer, and modern recording and audio information technologies allow them to be fully used.
Tall ones carry color and clarity more ..

As I recall, the main harmonics of the piano lie in the range of 30-4000 Hz, so the bottoms are our everything :)

Table of values ​​of frequency ranges

The table below shows the characteristics of the main (in terms of the human ear) areas of the sound range.

31 .. 50 Hz These frequencies give the music a feeling of power and strength. With excessive underlining can make the sound illegible and "boring", and in some cases can mask the high-frequency harmonic components of the signal.

80 .. 125 Hz Raising the frequency response in this area usually leads to an undesirable "buzz" of sound.

160 .. 250 Hz This is the most difficult part of the audio range. A significant amount of problems and ambiguities are associated with it. On the one hand, too much sound in this area will make your mix boring, and on the other hand, cutting these frequencies will take away the warmth and softness of the sound. In addition, this is where the main components of the sound of bass instruments - bass guitars and drums.

300 .. 500 Hz. Basic (fundamental) frequencies of strings and percussions.

400 Hz .. 1 kHz Basic frequencies and harmonics of strings, keyboards and percussion. This area is most important from the point of view of the "naturalness" of the sound of the composition. The “voice” of almost any instrument lies in the mid-frequency region. Be careful not to overdo the rise in the frequency response in this area, since the sound may become unnatural.

800 Hz .. 4 kHz This range is good for emphasizing and giving warmth to the sound of individual instruments. Too much sound in this area can easily cause listeners to acoustic fatigue, and an excessive rise in the frequency response in the 1 or 2 kHz area is likely to lead to an unnaturally delicate sound of instruments.

4 kHz .. 10 kHz Percussion, iron and small ("working") drum accentuation area. By adjusting the frequency response in the region of 5 kHz, you can achieve “approach / remove” and “blur / concentrate” the audio signal.

8 kHz .. 20 kHz This area is largely responsible for the subjectively perceived "quality" of the sound of the phonogram. Proper tuning of the frequency response in this area should give the composition a sense of depth and space. Too much sound in the high-frequency range makes the sound unnaturally thin and sandy.

-useful thing :)

Colleagues, how does this convolver implementation interpret stereo files as a filter? The left channel of the filter processes the left audio channel, the right channel of the filter - the right audio channel? Or the left channel of the filter is “direct sound”, the right one is penetration from the opposite channel?
The first option is a little easier to implement, but it is rather relevant for the equalization of speakers / rooms, the second option is more useful for headphones.

PS: Now, before uploading to the phone, I process music using the dolby headphone via foobar, but this is not very convenient. There is a desire to realize the same in realtime with the help of convolver, available in the subject. I want to understand whether it will be possible to do this with the help of V4A or have to write something myself.

PPS: It is incorrect to call convolver nonlinear processing, processing is just linear. You can call it a convolution, FIR-filter, FIR filter, non-recursive filter ... Nakraynyak linear processing.
It should be corrected in the first post.

So it seems there are more than enough samples with a dolby headphone.

Call convolver nonlinear processing is incorrect, processing just the same linear.

It is quite correct, because its linearity depends entirely on the sample used.

Here, I have a difficult question for those who use custom kernels with advanced sound settings ...
There are such items:

DAC direct By switching the DAC to the on position, the sound bypasses the output mixer, that is, less effort is spent on the signal path through the entire piece of hardware, in the signal path, and the DAC is connected directly to the headphone amplifier. Expected result: better sound quality using headphones, perhaps some insignificant battery saving
(Digital-to-Analog Converter, Digital-to-Analogue Converter - DAC - digital-to-analog converter An electronic device that converts a signal from a digital form (binary code) to analog, that is, continuous with varying voltage and / or frequency. It is used when outputting data from a computer and the need for their subsequent reproduction by analog (not digital) external devices, for example, acoustic consoles in this case headphones.)
DAC Oversampling Increase the sample rate. That is, it increases the number of values ​​read by the system from a music file for better sound. This setting changes resampling from 64 to 128 bits. Expected result: better sound quality using headphones; some slight additional discharge of the battery is possible. Improves sound quality.
FLL Tuning Turning on this parameter changes some sound engine configurations and / or some kernel parameters. The expected effect is the best sound quality using headphones, in general Full tuning is full tuning.

with them on / off, I don’t hear the difference with my pumped ears: D and through the sanheiser.
therefore the viper question already does all this? but, she does not have access to the core?
either I was deafened at all, or I do not understand Choto, or this is a show of the nucleus ... wow, compare who has the opportunity, and who the bear has not stepped on.

I'd rather make my impulse: DolbyHP + EQ under my headphones, ears and tastes :)
True, I do not really like DolbyHP myself, but this is probably already offtopic.

No, convolution is a linear operation. Even if the frequency response of the FIR filter is non-linear, it still remains linear, that is, it does not introduce new harmonics into the signal and, in particular, does not distort the shape of the sinusoid.

I, nevertheless, think that the calculation goes before the division into stereo channels.

Hmmm ... how's that? :)

In general, the essence is clear, it is worth figuring out for yourself, the benefit is not that difficult. Thanks to all who responded :)
