Audacity and Gnome Wave Cleaner

[jwt]

I am running Fedora 12 with Audacity 1.3.11-beta. Three years ago I had a Fedora system with Audacity and GWC(Gnome Wave Cleaner) working long enough to rip one LP and begin massaging the wav files with GWC to separate and clean the tracks. The system had a crash and for various reasons I am only now getting back to this project.
My problem is that GWC will open the wav files that I recorded with Audacity three years ago but will not open any I record with Audacity today. I can rip a track from a CD and GWC will open that wav file. I can put all of the files in the same directory and they all have the same permissions and music players will play all of the files. But when I try to open a 'new' Audacity wav file I get
'Failed to open /home/jwt/Music/Test.wav, no permissions or unknown audio format'
Anyone have any ideas?

I recently recorded and saved wav files from audacity which I then opened in gwc without problems...

On a terminal window type:

Code: Select all

file /home/jwt/Music/Test.wav

What does it say?

You should see something like this:

Code: Select all

$ file 24a-small-sample.wav
24a-small-sample.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 44100 Hz

What sample rate and bit depth are you using? Try 44100 Hz and 16 bits.

Thanks for the response. I spent the better part of a day on this. I loaded a different version of Fedora and a version of Ubuntu on different drives in an attempt to isolate this problem. It replicated so I gave up and posted here. Then last night I put the original drive back and put things back to the original configuration. I figured I might as well try it one more time and guess what, everything works perfectly. You gotta love computers. After 36 years of fixing them you'd think I would know they're still going to mess with me.

Like a friend of mine used to say... Probably yesterday the relative position of the planets was not favourable for you...

I had the same problem.
Scenario:

1) Opening some .mp3 in audabuggy
2) Export it to .wav.
3) Using GWC, it can't open it.

4) Load the audabuggy .wav in sweep
5) Export as another .wav from sweep
6) Then GWC accepts to load it.

Code: Select all

$ file b3sweep.wav
b3sweep.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo 44100 Hz

$ file b3.wav 
b3.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo 44100 Hz

I got no idea if the following has any use ! :

Code: Select all

$ hexdump b3sweep.wav -n 256

I have exported wav's in audacity that I was able to open in gnome wave cleaner with no problems...

What audacity and gwc versions were you using?

[Zbf]

Audacity in Debian Testing (1.3.12 Beta)
Same for GWC (0.21.5 very old version). I compiled GWC myself (0.21.11) but the result was the same.

[bgravato]

I'm on Debian too and I did some more tests today.

The files I worked on before were mono. And just tested that again and it worked. Then I tried to export a stereo file and it failed to open in gwc.

Also interesting the fact that the mono file when opened in gwc appears like a stereo track.

I'm running debian's (testing/squeeze) versions of both apps.

I will run some more tests...

[weltyj]

gwc uses libsndfile for all it's audio I/O, so any file format that libsndfile understands can be read by GWC. That's a lot of file formats, and libsndfile is pretty well tested.

I'd bet there is something not quite right about a wav file that libsndfile cannot parse, usually it's the header that has a problem.

Regardless something is broken in either audacity or libsndfile.

Cheers,
