sudo apt-get install ffmpeg lame flac vorbis-tools On Mac OS X: brew install ffmpeg lame Examples. Example 1 - converting from MP3 to OGG: ftransc -f ogg filename.mp3 The output file name for the above example will be 'filename.ogg' Example 2 - converting from MP3 to AAC, removing original file on success, using high quality preset: When converting to .aac from a source in m4a/mp4, you don't even need to re-encode: ffmpeg -i input.m4a -c:a copy output.aac. Note: FFmpeg tries to guess the output format from the output file name. If you need to force the format for ADTS (.aac file), use -f adts (e.g. when working with piped streams instead of files): flac some.wav -o some.flac For tagging, Kid3 provides a command-line interface, and recognizes tags in WAV files. kid3-cli has its own interactive command interpreter, so to copy tags from one file to another, you could use: $ kid3-cli kid3-cli> select some.wav kid3-cli> copy kid3-cli> select some.flac kid3-cli> paste kid3-cli> save kid3-cli Convert WEM into OGG. Extract the ww2ogg ZIP into the same folder with WEM files. There must be the file ww2ogg.exe. Place the reVorb EXE file inside the folder with WEM files and with ww2ogg.exe. Create a new text file in the same folder, the content will be the code you can find here below. If you're using Linux, use avconv instead of ffmpeg because ffmpeg is being deprecated: timidity input.midi -Ow -o - | avconv -i - -acodec libmp3lame -b 64k output.mp3 Or lame: timidity -Ow -o - input.midi | lame - output.mp3 See the FFmpeg H.264 Video Encoding Guide for more info on that. Get a recent ffmpeg. Go to the FFmpeg Download page and get a build there. There are options for Linux, OS X, and Windows. Or you can follow one of the FFmpeg Compile Guides. Because FFmpeg development is so active it is always recommended that you use the newest version that is 1. ffmpeg -i filename.opus -ab 320k newfilename.mp3. This command will convert an opus file to an mp3 file at 320 kbps bit rate. So far, so good. But if we take a look at the file, we do not get any of the metadata across into the mp3 (although the artwork is transferred). Now, if we were using another format (e.g. FLAC) we can do: FFmpeg can be used to convert any type of media file to other formats in a single command and the command to convert an MP3 file to an MP4 file is as below: ffmpeg -i input.mp3 output_simple.mp4 The file generated is an audio-only MP4 file and it can be played on a media player perfectly.
