Possibly related:

(1) Currently, Audacity is built without ffmpeg support. Yet libmp3lame cannot be specified, even though it is installed in $PREFIX/lib. I have tried manually creating $PREFIX/lib/audacity and copying $PREFIX/lib/libmp3lame.so into that directory, named as libmp3lame.so.0. But Audacity does not save or recognize this setting. Therefore, it cannot open mp3 files. But it does open and play ogg files without problem.

(2) When I launch audacity from command line, I see this warning, which vaguely sounds like it might involve a memory leak (I do not know):

(audacity:31904): Gtk-WARNING **: 13:59:56.401: A floating object was finalized. This means that someone
called g_object_unref() on an object that had only a floating
reference; the initial floating reference is not owned by anyone
and must be removed with g_object_ref_sink().

Honestly this is pretty much expected because PortAudio (the library used by Audacity for audio playback and recording) uses ALSA or JACK, neither of which is available in Termux.

Using Audacity, 32-bit Android 11. Audacity can open OGG files, as well as its own native projects. It can export OGG and WAV. I can use command-line ffmpeg to convert mp3 to OGG or WAV, manipulate in Audacity, export to OGG or WAV, then use ffmpeg to convert to mp3. Although I have LAME, Audacity does not recognize the library for import. It appears to use it for export, but I believe that is deceptive, as the exported mp3 fails some tests.

Bottom line: Audacity is useful. Not fully capable, but useful.

there is an version of portaudio which has been patched to use opensles https://github.com/Gundersanne/portaudio_opensles

Why not pulseaudio?

Portaudio now has Pulseaudio support, so probably need to rebuild to verify, see https://github.com/PortAudio/portaudio/pull/336

But I don't see Portaudio releasing new tags anytime soon
