repeat problem

Hi all,
I working on a DVD authoring software that uses sox to repeat/ transform a 2 seconds audio loop. I can't repeat the loop more than 7 times, which returns a 16.1 seconds long audio. If I try repeating 8 times, the result is the same as with 7, strange... (I run sox 14.0.1 on a Gentoo linux, with 3.1 GB free disk space) Any thought welcome ! Thanks / JP My input file: #ffmpeg -i a.wav ... Duration: 00:00:02.0, start: 0.000000, bitrate: 1536 kb/s Stream #0.0: Audio: pcm_s16le, 48000 Hz, stereo, 1536 kb/s The repeat operations [6,7,8] times: #sox a.wav b.wav repeat 6 && ffmpeg -i b.wav ... Input #0, wav, from 'b.wav': Duration: 00:00:14.1, start: 0.000000, bitrate: 1536 kb/s Stream #0.0: Audio: pcm_s16le, 48000 Hz, stereo, 1536 kb/s #sox a.wav b.wav repeat 7 && ffmpeg -i b.wav ...

No clues I'm afraid; it works fine for me on Linux 2.6.24-19-generic #1 SMP Fri Jul 11 23:41:49 UTC 2008 i686. I don't know where your .1 second is coming from either. Hmmm...
