Basically I want to record an audio. I am using recorder.js library which gives me blob data for wav file and i am converting it into a local 'audio.wav' file and storing it on device.
Now I want to convert it into amr format. For that I used amrnb.js which converts wav to amr and returns samples.
Now how samples can be converted into a file ?
Or else is there any way to record audio directly in amr format in recorderjs with low sampling rate and bitrate ?
Thank you.
