Android Question How to record sound directly from sound card

[watesoft]

In order to ensure the authenticity and clarity of the sound, I want to bypass the phone speaker and record the sound directly from the phone's sound card. Does the Android system allow this operation and which libraries are used?

Note: The sound is not from the microphone, but from an App inside the phone, which is a bit like the built-in recording function of an old tape recorder

I'm pretty sure that it is not possible.

It's a pity, but some phone's screen recording function can record the internal sound, I don't know how it works.

An app with the right permissions can capture the audio of another app that allows itself to be recorded.
