We have an Android9 environment, where we want to have echo cancellation enabled by default. A similar question was already made once here, but no answer was given.
We have developed a WebRTC App with a SIP Client included and we have a huge echo problem.
How can I enable echo cancellation by default in the system, on any channel. We need a system AEC always enabled. The /vendor/etc/audio_effects.xml looks like this:
<audio_effects_conf version="2.0" xmlns="http://schemas.android.com/audio/audio_effects_conf/v2_0">
your text</audio_effects_conf>
We tried different audio_effects configurations. The lib libqcomvoiceprocessing.so was also exchanged...without any change.
