Hi, the documentation on the microphone feature is pretty sparse.
Is this feature recording in mono or stereo?
What codec is the file returned in and what bitrate?
We have a huge number of audio files to record and don’t know if we can use retool vs. something like addpipe.com
Hello. I’m a Retool engineer and an audiophile.
I tried out the component and it recorded a webm with the Opus codec and 48kHz/mono and 32 bits per sample (all browser defaults from what I understand).
We use navigator.mediaDevices.getUserMedia({ audio: true }) and MediaRecorder without specifying any configuration. I’m guessing that the browser decides what codec/bitrate/sample-rate to use.
Since my mic’s are all mono, they’re likely a terrible test for Audiophile use-cases. I recommend trying to record on your target hardware, save the file (right click on the audio to do this) and examining the “Media Information” (using VLC or something like that).
