Mac OS X 10.6.8
Audacity 2.0.5
I did not obtain the .dmg installer
Hi there,
I’ve been using Audacity consistently for over a year and never had any problems. In the middle of recording an audiobook yesterday, the recording went from normal to this unusable shuddering, skipping, repeating and overlapping sound. Attached are a picture and a recording from where the recording goes from normal to crazy.
Is there any way to salvage the 2 hours of recording that are affected?!
The current 2.1.0 release ( Audacity ® | Free, open source, cross-platform audio software for multi-track recording and editing. ) already has a fix for an “uninitialized buffer” problem. This corrects playback buzz or crackle where the upper of multiple tracks started with or contained white space. That fix is unlikely to help recordings unless you are deleting the audio in a track and re-recording into it.
There is a problem that playback to external devices can be clicky unless you open Audacity Preferences then in the “Recording” section, reduce “Audio to buffer” to about 20 milliseconds (or some value well below the default 100 milliseconds). There is no fix for that yet.
Too high a buffer setting “might” sometimes cause recordings to click or have dropouts after the recording has been going on for a long time. A handful of people have reported this and some (not all) have said reducing buffer solved it.
Your sample doesn’t really sound like that - it looks more like the data got corrupted somehow.
Anyhow I would try setting Audio to buffer as low as it will go while still letting you record without dropouts, and update to 2.1.0.
