If aiff is used instead of wav, it is also ok: c:\\>sox.exe 24bit_file.flac test.aiff c:\\>flac test.aiff flac 1.2.1, Copyright (C) 2000,2001,2002,2003,2004,2005,2006,2007 Josh Coalson flac comes with ABSOLUTELY NO WARRANTY.

A mono file whose single channel is marked "center" is not accepted. Run flac with the option --channel-map=none (it's undocumented, but it's there) to override the default. In the forthcoming version 1.3.0 of flac, the error message has been changed to point to this option: flac 1.3.0pre3, Copyright (C) 2000,2001,2002,2003,2004,2005,2006,2007,2008,2009 Josh Coalson flac comes with ABSOLUTELY NO WARRANTY.

Type `flac' for details. tst1.wav: ERROR: WAVEFORMATEXTENSIBLE chunk with unsupported channel mask=0x0004 Use --channel-map=none option to store channels in current order; FLAC files must also be decoded with --channel-map=none to restore correct order. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=110706&aid=3610258&group_id=10706 ------------------------------------------------------------------------------ Minimize network downtime and maximize team effectiveness.
