-b:a is for CBR (constant-bit-rate), which should be compatible with most old players, but may take more file-size.

Note to see docs about bit-rate argument's differences.īecause maybe that option is the most important one, as it decides the 'quality' versus 'output size' versus 'old mp3-player compatibility'. But -q format may not be compatible with some old player-hardware. b:a 192k - Converts the audio bit-rate to be exact 192 KB/s (192 kibibit per second).īut maybe use -q:a 2 instead, which allows the encoder to pick from 170 to 210 KB/s quality-range (average 192 KB/s). So used here to make sure it is stereo (2 channels) For input streams this option only makes sense for audio grabbing devices and raw demuxers and is mapped to the corresponding demuxer options. For output streams it is set by default to the number of input audio channels. For output streams it is set by default to the frequency of the corresponding input stream. vn - Disable video, to make sure no video (including album cover image) is included if the source would be a video file You could use this command: ffmpeg -i input.wav -vn -ar 44100 -ac 2 -b:a 192k output.mp3Įxplanation of the used arguments in this example: I guess that the mp3 codec isn't installed.
