About MediaEncoder, that Termux API uses: https://developer.android.com/reference/android/media/MediaRecorder.html

And Termux API can use more than 3 audio codecs.

Can use:

AAC
AAC_ELD
AMR_NB
AMR_WB
HE_AAC
OPUS
VORBIS

However, the Termux API describes only 3 methods. But, perhaps, we will use all the methods that are available in Android
