Transcode m4a (Apple Lossless) to flac

[geofstro]

Hi,

Is this possible? If so I will very much appreciate an example of the command to achieve it.

Some variant of the following methods look like they should work.

ffmpeg -i audio.flac -acodec alac audio.m4a

avconv -i audio.m4a -acodec flac audio.flac

I can't get them to work though.

I wish there were a list available for what should be fairly simple transcodings like this. After all we're just going from one lossless compression format to another and they are both very similar, so surely it should be simple to achieve?

Thanks,
geoff
