Ubuntu - Sound - Convert FLAC to MP3
for f in *.flac; do flac -cd "$f" | lame -b 320 - "${f%.*}".mp3; done
or
for a in ./*.flac; do ffmpeg -i "$a" -qscale:a 0 "${a[@]/%flac/mp3}"; done
Convert files in all sub-directories
find . -type f -name "*.flac" -print0 | while IFS= read -r -d '' file; do echo "$file"; flac -cd "$file" | lame -b 320 - "${file%.*}".mp3; done
Convert files in all sub-directories to a different bitrate
find . -type f -name "*.mp3" -print0 | while IFS= read -r -d '' file; do echo "$file"; lame -b 192 "$file" "${file%.*}".192.mp3; done
NOTE: The bitrate is set to 192 kbps.
Convert files in all sub-directories to a different bitrate, but only if they have bitrates above a specific value
Using only built in Bash functions
find . -type f -name "*.mp3" -print0 | while IFS= read -r -d '' file; do echo "$file"; [[ $(file "$file" | sed 's/.*, \(.*\)kbps.*/\1/' | tr -d " ") -gt 192 ]] && lame -b 192 "$file" "${file%.*}".192.mp3 && mv "${file%.*}".192.mp3 "$file"; done
NOTE: This uses the file command to determine the bitrate.
- Unfortunately, sometimes the file command does not return the bitrate and returns something like Audio file with ID3 version 2.3.0.
- For these files, the $(file “$file” | sed 's/.*, \(.*\)kbps.*/\1/' | tr -d “ ”) part will not work.
- The bitrate is set to 192 kbps for any file that has a bitrate above 192 kbps.
Using mp3info
find . -type f -name "*.mp3" -print0 | while IFS= read -r -d '' file; do echo "$file"; [[ $(p3info -r m -p "%r" "$file") -gt 192 ]] && lame -b 192 "$file" "${file%.*}".192.mp3 && mv "${file%.*}".192.mp3 "$file"; done
NOTE: This uses the mp3info command to determine the bitrate.
- This mp3info command needs to be installed with sudo apt install mp3info.
