Converting to ulaw

[ilynch]

After editing a file in Audacity, I convert export it as a ulaw .wav file. However, these files always have about twenty seconds of dead air at the end of them that was not present in the original. Is this a problem with a setting or something similar? I have had other Audacity users tell me that they get the same result.

Thanks.

It's most likely an old resampling bug in Audacity 1.2 that occurs if the sample rate of the track (above the mute/solo buttons) does not match with the project rate (bottom left of the Audacity window), If the rates don't match, click in the Track Panel to select all the track, and Project > Quick Mix to resample the track to the project rate. This will add silence at the end of the track. Delete the silence, then you can export without adding silence because the rates match so no resampling will be needed.

Audacity 1.3 Beta does not have this issue.
