Bug Description

Binary package hint: audacity

Audacity 1.3.9 on Ubuntu Karmic Koala (v9.10)
(installation .deb pkg from repositories: audacity-1.3.9-6.deb from 10/26)

Steps to create bug:
1 Open Audacity
2 Select Generate
3 Select DTMF tones
4 Set Amplitude to 0.6 duration: 000.020 seconds default tone/silence ratio
5 Click OK to generate dtmf
Tone that's generated sounds crisp with no distortion.
6 Select File
7 Click OK on Meta Data screen
8 Select EXPORT (as AIFF) and saved as dtmf.aiff
9 Closed Audacity without saving project
10 Opened Audacity
11 Select IMPORT and choose dtmf.aiff
When the file is imported its completely distorted with track full of noise.

I took the same aiff file created by Audacity on linux and copied it to my Powerbook via a thumbdrive.
On the Powerbook G4 w/OSX 10.5.8 it imports and sounds fine without any distortion into Audacity 1.3.9 (08/29 OSX build)

I cannot confirm this bug. The export and the import works without corrupting the sound.

Ben,

Are you using the pre-built .deb from the repos, or another source? Also, did you use the .aiff I attached so I can rule out that being something odd on my system?

Yes, I am using 1.3.9-6 from the repository. I created a .aiff file and downloaded your file; both were fine. Do the file works with other applications? Do it sound ok with "mplayer dtmf.aiff"?

While I don't have mplayer installed my file worked OK with Amarok, Rhythmbox, Xine, Totem and VLC.

After trying those apps out I then did a complete uninstall of the current version of Audacity on my computer. Then powered down. After a few minutes I came back and did a complete reinstall of the application, including the one in the archives that says audacity-dbg. Same distortion problems. This is maddening!!

Have never used the .dbg mode. Would it show anything that might help figuring out what is going on here? If so, how do I envoke dbg mode in Audacity?

Am heading out of the house right now so will check mail later this evening.

Your file is OK here as well. When you look at the file in Audacity, does it look distorted or does it look OK? That'll help us sort it out whether it is the import or the playback that goes wrong on your system.

Tested with Ubuntu 11.04 and cannot replicate. File is OK. Could be related to performance? What is your CPU??
