How to specify sample and bit rates for the recording?

Closed this issue a year ago · 3 comments

Is there a way I can specify the following while recording:

Channels: 1
Sample Rate: 16000
Precision: 16-bit
Bit Rate: 256k
Sample Encoding: 16-bit Signed Integer PCM

I have seen the recordings done via native MediaRecorder have got a single channel and less sample and bit rates.

@chrisguttandin can you please check this?

The number of channels and the sample rate is determined by the MediaStream that you record. At least that's how it should be. If you experience something different it's probably a bug.

There is currently no way to define the bit depth. Luckily it's hardcoded to 16 bit.

Does this answer your question?

I'm closing this since I recently added a description on how to change the sampleRate as part of #674.

There is already already another issue (#643) which tracks the missing audioBitsPerSecond option.
