Not only because both PCM and WAV share most the similar codec, but also the high quality lossless WAV. Actually turn PCM into WAV should be the most efficient method to remain the high quality audio format. To record WAV files to an Audio CD the file headers must be stripped and the remaining PCM data written directly to the disc as individual tracks with zero. WAV is a file format for a computer to use that cannot be understood by most CD players directly. The commonality is that both audio CDs and WAV files encode the audio as uncompressed PCM.There are two major variants of log PCM: mu-law (u-law) and A-law. Or convert between raw types.Log PCM is more often used in telephony and communications applications than in entertainment multimedia applications. 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).The audio formats of the item must be PCM, MP3 and WAV files. WAVE format is a standard digital audio file format that is used to store waveform data.This application records the voice of the microphone. It is saved in the WAVE format.There are also other containers that can contain raw audio packets, like pcm_bluray.If you want to create a raw file, don't use the WAV format, but the raw one (as seen in the table above), e.g. You can change it by specifying the audio codec and using the WAV file extension:Ffmpeg -i input -c:a pcm_s32le output.wavWhich will create a WAV file containing audio with that codec (not a raw file). As well, ex:Ffmpeg -f u16le -ar 44100 -ac 1 -i input.raw output.wavThe default for muxing into WAV files is pcm_s16le. For instance, to convert a "raw" audio type to a ".wav" file:Ffmpeg -f s32le input_filename.raw output.wavYou can specify number of channels, etc. le means "little endian" coding for the samplesYou can see a list of supported sample formats by inspecting the ffmpeg -formats output:DE f32be PCM 32-bit floating-point big-endianDE f32le PCM 32-bit floating-point little-endianDE f64be PCM 64-bit floating-point big-endianDE f64le PCM 64-bit floating-point little-endianDE u16le PCM unsigned 16-bit little-endianDE u24le PCM unsigned 24-bit little-endianDE u32le PCM unsigned 32-bit little-endianThese represent all the built-in raw audio sample formats.FFmpeg can take input of raw audio types by specifying the type on the command line. s means "signed" (for the integer representations), u would mean "unsigned"
