If you are looking for a tool, take a look at the metaflac command line utility. metaflac --list file.flac returns all metadata in a FLAC file > 2) I decode using the option --skip=0 --until=1.

When I use flac -d --skip 0 --until 1 file.flac I get a WAV file with a single sample per channel. I tested with a mono and a stereo file. Can you perhaps share the full command line you're using? _______________________________________________ flac-dev mailing list flac-dev@xiph.org http://lists.xiph.org/mailman/listinfo/flac-dev
