The default for muxing into WAV files is pcm_s16le.

as well, ex:įfmpeg -f u16le -ar 44100 -ac 1 -i input.raw output.wav For instance, to convert a 'raw' audio type to a '.wav' file:įfmpeg -f s32le input_filename.raw output.wav These represent all the built-in raw audio sample formats.įFmpeg can take input of raw audio types by specifying the type on the command line. You can see a list of supported sample formats by inspecting the ffmpeg -formats output:ĭE f32be PCM 32-bit floating-point big-endianĭE f32le PCM 32-bit floating-point little-endianĭE f64be PCM 64-bit floating-point big-endianĭE f64le PCM 64-bit floating-point little-endianĭE u16le PCM unsigned 16-bit little-endianĭE u24le PCM unsigned 24-bit little-endianĭE u32le PCM unsigned 32-bit little-endian le means 'little endian' coding for the samples.s means 'signed' (for the integer representations), u would mean 'unsigned'.Raw audio in FFmpeg can take several different 'forms', i.e. For example, you can read and write raw PCM audio into a WAV container.

FFmpeg can read various raw audio types (sample formats) and demux or mux them into different containers (formats).
