Audio GLITCHES
Describe the bug The audio signal shows many glitches
To Reproduce Record audio on receiver side (e.g. connecting speaker in USB sound card to mic in a PC running Audacity)
Expected behavior The audio signal has no glitches
Your system information:
- TRIfA Version: 1.0.231
- App from Google-Play : TRIfA
- Android OS Version: Android 9
- Device: HUAWEI P smart
Add screenshots, if possible
Additional context The output volume seems to be very low! I tried several different combinations of settings without success (audio buffer, frame size, sampling rate, UDP active, force UDP mode).
Some years ago I solved a similar problem by opening the audio interface with CALL_MODE instead of COMMUNICATION_MODE
first let me say that google play is no longer the main distrubution channel for this app. please install the latest version from https://github.com/zoff99/ToxAndroidRefImpl/releases it is signed with the same key as the google play version.
which tox client is the receiver side using? and are you calling audio only or also video? if possible give as much details as you can.
both smartphones are exactly as described above, and both see the glitches. This is an "audio call" from TRIfA to TRIfA. I noticed this behavior some years ago already and I still assume that the "call mode" may solve the problem.
did you change it in the source code and compiled yourself to fix it, or what do you mean by "Some years ago I solved a similar problem" ? TRIfA uses native code for audio recording and playback via OpenSLES
it was my own app, but the effect was exactly the same I saw many comments all over the internet claiming that the audio quality is much better in call mode
audio mode is tricky stuff on android. i ran into lots of issues depending on the device. what sort of audio glitches do you have? can you give more details? is it "just" bad quality audio or choppy (parts missing all the time), or sounding like robot?
i can let CI build a debug version with COMMUNICATION_MODE, could you test that version?
I can repeat the tests tomorrow and upload the file(s) with the glitches, but sorry, I cannot do much more than that. Maybe you could just add a configuration option to allow selecting the "call mode" on own risk, as an experimental feature. That would be great.
can you install and test with the nightly version? it can be installed alongside the regular trifa
https://github.com/zoff99/ToxAndroidRefImpl/releases/download/nightly/TRIfA-nightly.apk this has it changed: https://github.com/zoff99/ToxAndroidRefImpl/commit/7ff1a9c89e1878c6276044d7196a69f4565b6a2c
it has also turned logging on. if you can still "repeat the tests tomorrow and upload the file(s) with the glitches" that would be super.
unfortunately the same behavior attached you find 2 example files with some glitches sweep_test_with_glitches.zip
