How and with what to write data from the MediaStream object?

Question

JavaScript

How can I get and encode the received data of a MediaStream object? Don't offer RecorderJS RecorderMp3JS etc. I have already tried these libraries, in some browsers they are normal, in some they distort the audio track. I settled on the standard MediaRecorder, BUT it is not supported by Edge until version 17 (yes, its share of users is small, but the site has a large percentage of people who use it). Is it possible with the help of "dancing with a tambourine" to process a MediaStream using an AudioContext?
