Can ffmpeg convert audio to raw PCM? If so, how?

Question

I\'m currently using ffmpeg to convert FLV/Speex to WAV/pcm_s16le, successfully. However, I now need the output format to be RAW, tha

Answer 1

convert mp4 file to pcm

ffmpeg -y  -i input.mp4  -acodec pcm_s16le -f s16le -ac 1 -ar 16000 output.pcm

you can also use it to convert mp3 to pcm

ffmpeg -y  -i input.mp3  -acodec pcm_s16le -f s16le -ac 1 -ar 16000 output.pcm

key params means:

-f s16le … PCM signed 16-bit little-endian samples

-ac 1 … 1 channel (mono)

-ar 16000 … sample rate 16000Hz

Answer 2

Give this a shot:

ffmpeg -i input.flv -f s16le -acodec pcm_s16le output.raw

You can get these options by running:

ffmpeg -formats
