Ardour 5.12.0 on Fedora27.
I tried to import data from an existing Zoom R24 project, to find that Ardour refuses to import the WAV data files. According to the import dialog, the files are “not usable”.
Ardour seems to use libsndfile, so I tried sndfile-info:
Error : Not able to open input file STE-000.WAV. File : STE-000.WAV Length : 40424480 RIFF : 40424472 WAVE fmt : 16 Format : 0x1 => WAVE_FORMAT_PCM Channels : 2 Sample Rate : 44100 Block Align : 4 Bit Width : 16 Bytes/sec : 176400 LIST : 393164 *** Found weird-ass zero marker. Jumping to end of chunk. Request for header allocation of 786328 denined. *** Offset is now : 0x5FFFC *** Unknown chunk marker (262D420) at position 393212. Exiting parser. Error in WAV file. No 'data' chunk marker.
However, most other tools (mplayer, audacity) do not have any problems with these WAV files.
