Works great with Headset, speaker, and bluetooth...

I agree. Works great. I feel it's every bit as good as viper and I've sworn by viper for years so that's saying a lot. I had legacy viper working on bliss rom Q. Recently returned to stock and can't get it working again. Installed james dsp, no driver issues, process stopping, etc. James dsp has lots of tweaking to play around with. It's a good app.

Not to be that guy or anything but I recall you said drivers of v4a and this being separate. I haven't been able to get magisk v4a to work because of driver install issues. In actually pleased but... I installed this app via magisk and all of the sudden v4a had its drivers working as well... coincidence... maybe

Is there a way to install this without needing to use the volume keys in magisk? I'm trying to install this on my android headunit and i don't have physical volume keys.

Was same error on my Poco X3 phone after im installed the 12.0.4 xiaomi rom and any sound modifications, or the long presses didnt work with hardware volume buttons. Just use Volume Styles app from Google Play thats will fix it.

Thank you for this and for keeping it updated for use on A11. It's working well for me on a Pixel 5 w/ Magisk 21.1. I ran out of runway with V4A on A11 and I'm leaving it behind forever ( I hope).

I didn't see it in the OP - is there a guide somewhere as to how to properly use all the settings and effects?

Version JamesDSP 3.3 still doesn't work on EMUI 9.1 (Android 9)

RE to previous suggestions:
Narsil also modifies audio_policy and audio_effect. So I suggest you try it without AML and Narsil, it's easy to add modules in Magisk anyway.
If I don't install/enable AML but keep JamesDSP enabled, the phone fails to initiatize on Magisk start, throws to Safe Mode, and eventually just resets all Magisk modules to disabled. It's clearly a hard dependency on this device.

If I enable AML and JamesDSP 3.3, it boots without issue, but JamesDSP toggles don't do anything. Only if I downgrade to JamesDSP 2.7 it's back to working state.
Seems I'm not alone:

Is there any place I can collect logs to help investigate this?

Can u put the functionality of Neutralizer app from playstore? It basically allow u to equalize ur system to get a flat audio response with the tested audio source (headphones, phone loudspeaker...).

Works lovely on my Samsung A71 (SM-A715F) latest official stock, magisked.

Thanks for this fine piece of software!

Your app dosent change effects at all on A10 Los... installation proces is suceess...
Works fantastic for me on my pixel 4 xl A10 magisk 21.4, DU 14.7 custom rom with audio modification library, viper4android, ainur narsil and jamesdsp.. plus 8 other modules installed... I think it's your setup/device/os and/or the modules you have installed etc. Maybe a combo of all 3 or none. We honestly don't know because you didn't provide any other info. So we really can't help you...

Hey guys, I have red almost every pages and still can't figure out how to install the mod without buttons! I have a recovery but it's a modified one that can only uninstall stuff (weird i know, considering it's twrp). I'm trying to install it on a car head unit. Even tried some volume apps but won't work... Please help, I'm desperate 😅

Hi all coming from viper4 which whatever ... I used the magisk module on my pixel 5 rooted with canary magisk. To be honest I don't know how to setup this app. I could send screenshots of what settings I am currently using. There is NO difference whether I have the master switch ticked or not. Anyone can offer some advice, presets or anything would be greatly appreciated.

I've always used Viperfx i also installed Jamesdsp and it shows me notification speaker PID:4388 means that is in process and it works? I have tried various setting and it seems to work,but i have the doubt about this notification someone can confirm me that is the process. Thanks in advance

    Notes:
    Convolver have been tested working even in stereo impulse response with 16121304 samples per channels on Snapdragon 820

    If you look at the source code from Java part, you will find some are similar with Viper4Android, but this is not true.
    Viper4Android only open source it's interface, their core drivers source code have never been released.
    For convenient sake, I copy some interface code to accelerate my development.

    How to compile the source code?
    Use Android NDK & Eclipse

    New JDSP is finally here everyone!

    Anyone give links for PRESETS and IRS.... I downloaded from an old post , but that's causing the app to crash!
    1) You can download Convolvers and DDC from
    https://androidfilehost.com/?fid=1322778262904011552

    Unzip and
    - copy IRS files from Kernel folder to Internal memory: /JamesDSP/Convolver
    - enable Convolver and select an Impulse Response filter

    - copy VDC files from DDC folder to Internal memory: /JamesDSP/DDC
    - enable ViPER-DDC and select a DDC file

    Btw, with IdealEQ.vds for DDC file, there is also a notable increase in Volume (tested for Speaker and Headset)

    2) For Equalizer, enable Hybrid equalizer (for Speaker, Headset and Bluetooth), select Custom, and from the top-right menu chose Save preset, name it like MyDefault

    Open by eg MiXPlorer, Internal memory:
    /JamesDSP/Presets/MyDefault/james.dsp.speaker.xml
    (repeat the same for Headset and Bluetooth XML files)

    edit as Text file, find the line starting with
    <string name="dsp.tone.eq.custom">

    and replace by 'Small speaker' parameters:
    <string name="dsp.tone.eq.custom">7.0;6.8;6.4;3.5;0.0;0.0;0.0;0.0;0.0;0.0;0.0;-3.5;-6.4;-3.3;-3.5;</string>

    Then in JamesDSP, top-right menu, chose Load preset and select your MyDefault

    JDSP has been updated to v1.7! See james' github for changelog, this installer uses the hq libs

    Can you define HQ and SQ in specific terms?

    Yes. @Zackptg5 Yes, for sure.
    HQ process audio using float 64 data type, although Android audio framework most likely provide only 16 bit data, this doesn't mean it is unnecessary, because float 64 guarantee less rounding error, thus less noise.
    SQ mode is pretty standard in DSP, float 32 satisfy most situations, this is most power saving, and fastest.
