[linux-audio-user] sample file conversion, logic -> ardour

[Atte André Jensen]

Hi

I recently played a gig with my quartet, and we arranged with a mac-dude
that recorded the thing into his laptop/mac/logic. Today I received the
DVD with the files, and I have trouble loading them into ardour.

they are 44.1K mono files in aif-format, and when simply converting them
with "sox file.aif -r 48000 file.wav" and importing them into an 48000
ardour session I get all noise. I guess they're either 32bit or it's the
little endian issue (that I don't understand) or both.

Here's what "file" has to say:

atte at ajstrup:~/music/seq/jazz$ file audio_recording_041.aif
audio_recording_041.aif: IFF data, AIFF audio

And on the same file converted as mentioned above with sox:

atte at ajstrup:~/music/seq/jazz$ file audio_recording_041.wav
audio_recording_041.wav: RIFF (little-endian) data, WAVE audio,
Microsoft PCM, 32 bit, mono 48000 Hz

The file sizes:

atte at ajstrup:~/music/seq/jazz$ ll audio_recording_041.*
-r-xr-xr-x 1 atte atte 27M 2006-10-12 11:56 audio_recording_041.aif
-rw-r--r-- 1 atte atte 30M 2006-10-12 20:03 audio_recording_041.wav

The .aif file plays back just fine in mhwaveedit, and is 3:33 mins long
(mono). The .wav file is a little shorter (2:40 mins), and is all noise
when played back by mhwaveedit.

Any pointers that would help me convert these files into something that
sounds in ardour is greatly appreciated. Batch conversion (preferably
with sox) is a must, as there are over 100 files...

Thanks in advance for any response!
