Ubuntu – Convert lossless m4a to flac

convertflacm4asound

I tried to convert a file with pacpl, but I get the well-known "256" error.
With the -v flag, the FAQ of pacpl tells me:

"The file you are trying to convert is a lossless .m4a file. The
format is not yet supported by FAAC/FAAD."

Since faac/faad seems to be used in every other converting tool on Ubuntu, how can I successfully convert formats?

Best Answer

You can convert an m4a file to flac with the ffmpeg command-line tool:

To install ffmpeg:

sudo apt-get install ffmpeg

To convert:

ffmpeg -i filein.m4a -f flac fileout.flac
