using FFmpeg

Use for i in *.flac ; do ffmpeg -i "$i" -acodec libmp3lame -q:a 0 $(basename "${i/.flac}").mp3; done to convert multiple FLAC files to MP3 files, preserving filenames. Use ffmpeg -i foo.flac -acodec libmp3lame -q:a 0 bar.mp3 to convert a single FLAC file to a single MP3 file, where foo.flac is the input file and bar.mp3 is the output file.

explanation

Note

This is an incomplete explanation.

• -q:a 0 encodes the MP3 file at variable bitrate with a range between 220-260 kbit/s, the highest available quality.¹

• The method of iterating through a for loop with FFmpeg and preserving the filename was introduced to me by an answer on Unix & Linux Stack Exchange by Ketan.
