Navigate to the directory your audio files are in with the cd command.
We can see what formats are acceptable by typing: ffmpeg -formats Give this a try: sudo apt-get install ffmpeg Especially note the VBR mapping table marked 'LAME Bitrate Overview'. FFmpeg MP3 Encoding Guide: FFmpeg Trac's great guide to encoding to mp3.Whatever sounds best on your playback hardware.
Some experimentation might be in order with good choices for the bitrate being taken from the following LAME 'allowable' standards: 64k, 80k, 96k, 112k. Since your input file has an overall bitrate of 71.7 Kbps and a maximum bitrate of 93.8 Kbps we could perhaps fudge the numbers a little and use the following: ffmpeg -i show.m4a -c:a libmp3lame -b:a 96k output.mp3 Encoding to MP3 with a variable bitrate of 70-105 Kbps can be mapped to FFmpeg with the -q:a 8 option as below: ffmpeg -i show.m4a -c:a libmp3lame -q:a 8 output.mp3Īnd I suspect that this is your best option with your input file.Ĭonstant Bitrate (CBR) Encoding is a little over-used IMHO but if this suits your playback equipment best then it is a valid choice. This would be my own choice if only for the reason that the original AAC file is also a VBR file. And FFmpeg is certainly the best tool for both of these! So you actually have two reasonable choices: encode to a Variable Bitrate MP3 file or simply decide on a suitable bitrate for Constant Bitrate (CBR) MP3 encoding. It's free, however, the output file name adds, which is not friendly.I note that your input file is actually a Variable Bitrate (VBR) AAC file with an overall bitrate of 71.7 Kbps and a maximum bitrate of 93.8 Kbps.
