[MOD][08/02]Xperia: Fidelity 7.0 - Audio optimization script for Android devices

This project is derived from [MOD][TWEAK][03/05]Nexus S: Fidelity 2.0 - Ultimate Low latency audio playback. I started this project when I owned Nexus S phone trying to optimize system playing very low alsa buffer size for @6ms playback without stuttering. It’s been improving since then even I no longer use Nexus phone as optimizing OS to have with similar goal as what I did in Fidelizer is still possible in Android. So I kept improving things in Xperia phone with satisfying result.
This script will do the following changes for better audio performance:
-Optimize CPU for suitable audio playback ones while still keeping good juice
-Optimize kernel resource scheduling granularity for lower latency and more responsive
-Optimize audio process and I/O priorities from lowest level to real-time level ensuring highest performance of audio processing
-Optimize file I/O scheduling for lower CPU usage and latency with good performance
-Optimize IRQ affinity for multi-core platform
-Optimize real-time clock frequency for high resolution time domain
-Optimize Voodoo Sound configuration for optimal volume and purist without cheap tricks like re-sampling and pseudo anti-jitter mechanics.
Instructions:
1. Root your phone with recovery support.
2. BusyBox is not required but it’s recommended to have BusyBox installed regardless.
3. Verify that your phone has init.d support. You can learn how to enable init.d support from this topic if your phone doesn’t support it yet.
4. Boot to recovery and flash xperia_fidelity_v7.zip file then reboot
5. If your device doesn’t support recovery, extract ‘S98_xperia_fidelity’ file inside archive to ‘/system/etc/init.d’ and download Script Manager running that file with su+boot to instead.
6. You should have your phone with audio optimization script. Try playing music and be impressed with performance.

Nice Job, not only sound is improved, but my phone seems smoother also!
Underclocked to 652Mhz and still rocking!
Xperia Arc

It works on any devices. I added Xperia name because I'm using it as phone right now and Nexus Fidelity includes patched low latency audio library so I don't want to cause confusion with that name.

How u would do? It was so simple but we all was so stupid to find the how it work, it was just abt to copy and paste
In mixerpath.xml u just need to find the path
Speaker-and-headphone section
And Copy everything in that path and
Then delete everything in speaker section and paste the copied one, so simple I was
So much investing time nearly one month and now look the simplest way to do so stupid things take my time
But finally it works
Report if there is any bug
And I will try to push bass inside the two speakers without distortion let's try

ask
I have a question:
we all know our xperia z1 loudspeaker is only 1 (mono) not stereo.
how can we produce stereo sound from only 1 speaker?
I checked your mixer_paths.xml.
it contains
<ctl name="TFA98XX_PARAM_TYPE" value="Playback" />
<ctl name="TFA98XX_CHANNEL" value="Both" /> --> I think it was taken from xperia z2 mixer_path.xml
<ctl name="TFA98XX_SPKR_AMP" value="1" />
<ctl name="DAC1 Switch" value="1" />
I wonder, will it working with our xperia z1?
thank you.

It means u don't understand BTW it's not the speaker settings and one more I uploaded new zip and this lines are useless ignore if u compare with original mixerpath.xml u will see
New lines begin from
CLASS_DSM_HPHL something like this u will see it
Rx 7 is for right speaker (actually it's loudspeaker)
Rx1 and RX2 is for left speaker (it's earpiece speaker) but RX2 don't work so
Logically rx7 for right and rx1 for left, try ur self,,

great
so far, the "stereo sound" sounds great !! -> I disable speaker settings sony(clear phase n xloud) to get better sound though.
I only implement "stereo" tweak, not headphone&microphone boost.
Great job !!:good::good::good:
anyway I have tried your bass mod, it sounds terrible.

1 more question
btw before I forget this thing, should we change "RX7 Digital Volume" value into 100 instead of 90 ??
because RX1 Digital Volume & RX2 Digital Volume values are 100.

i don't understand how we can have a stereo mode if we have only 1 loudspeaker. what's the second loudspeaker?

Share your Viper4arise profiles and setup (Kernels)

I've just created this thread for everyone to share their favourite profiles. I've seen similar threads to this but they have been for viper4android and aren't very active. I was hoping people could share what they use for it. I'm personally looking for a rap profile especially for music like Eminem. If someone can share a good profile for that I would really appreciate it.

This is what I'm using currently but looking for something better for rap/hip hop music.

[GUIDE] [SOUND MOD] Viper4Arise ***Best sound experience on Android***

After trying out a lot of different sound mods and apps and patches I always came back to Viper4Arise. Simple to use, great sound quality and a lot of customization.
There are many Arise editions but I find the attached one simplest to use.
Steps:
1. Flash the attached file (ARISE Sound Systems Deuteronomy 2.2.3 Mac 'n Cheese Edition FINAL) through TWRP
**For Android Oreo flash the included (ViPER4Android_2.5.0.4_Wonder_Wicked_Witch_12-Jan-2018.zip) file through TWRP instead.**
2. Reboot to OS
3. Install Busybox (https://play.google.com/store/apps/details?id=ru.meefik.busybox) from Play Store
4. Open the Busybox app and install busybox
5. Enter the Viper4Arise app
Done!
Next, you need to set up the sound mod.
*I only use Viper4Arise for my headphones so I will cover only that part but you could test out different settings for other audio outputs*
In the Viper4Arise's menu go to UI setting and set it to expert.
Go to Headset and click Enable, I suggest you put on your headphones now so you can hear the changes in the sounds yourself and tweak them to your liking.
My settings on Redmi 4X are:
Spectrum Extension (enabled): Strength: 0,5
FIREqualizer (enabled): Preset: Acoustic
Convolver (enabled); Impulse Response: BBE2.irs (extract the attached BBE 2.rar into Viper4Android/Kernel); Cross Channel: 30%
Dynamic System (enabled); Listening Device: High-end headphone v2; Dynamic Bass:5%
Viper Bass (enabled); Bass mode: Natural bass; Bass Frequency: 100 Hz; Bass Boost: 3,5 dB
Viper Clarity (enabled); Clarity mode:Natural; Clarity:6 dB

wow your profile settings and irs file make the sound on my headset amazing ??? thx ?

How much sound difference between viper and a dedicated dac say dragonfly black?

[Viper4Android] Bullets Wireless DDC

I decided to make a separate thread, because DDC is a more audiophile oriented topic .
Yes, I've made a DDC for Bullets Wireless. Take this with a grain of salt, because I did all tunings by ear, but the main focus was making it sound as "flat" as possible, because believe it or not, Bullets Wireless are not even close in regards of audio quality and accuracy to what original ads tried to convey.
So, there are two revisions of the DDC curve:
- Rev 1 - plain simple removal of the most annoying resonances. Least intrusive and most effective, has only 4 pinpoint adjustments, rest can be achieved using a built-in EQ.
- Rev 2 - an attempt to flatten frequency response as much as humanly possible. Audio-Technica M40x (with Brainwavz HM5 angled pads) was used as a reference headphone. Has over 20 adjustments. Might sound highly personalized, because I am overly sensitive to 2-4kHz range.
Please report on perceived audio quality and how does it compare to studio headphones. I am most interested in accuracy of the first DDC profile, because shape of ear canal might actually affect resonance points.

What's is this?? Bullets wireless DDC.zip is a flashable zip? I'm little confused

It's just a plain ZIP with files that go into Viper4Android folder. It's not flashable.
You need to unzip it, and have Viper4Android FX in order to use it.

Thanks for the DCC profile. Definitely an improvement! Using it on a 6T but still the wireless bullets. Sound great in Rev 2 with a bit extra bass added in the bottom end.

Damn, just what I needed. Thank you so much!
