wavutils is a tool set that process wav file. like follow:
bin/ ├── pcm2wav - convert pcm to wav ├── wav2pcm - convert wav to pcm └── wavinfo - show info of wav
git clone https://github.com/smallmuou/wavutils
cd wavutils
sudo ./install.sh- pcm2wav - convert pcm to wav
pcm2wav channel samplerate bitspersample pcmfile wavfile
# sample
