Crashing

Post by gwilliamson » Fri Sep 09, 2011 7:00 pm

I have been using audacity for sometime to clean up the recording of our Church services to put on CD. Originally, the service was being recorded on a single track. In April, our church upgraded our sound equipment. We now actually have a mixer, presonus studiolive 24, and are using their software to record to the computer. I am still using audacity to edit the recording since I am more familiar with it. The company that installed the equipment has not been supportive in the post production phase. Here's my question... for the past couple months during the editing process, audacity crashes multiple times. Each mic is on a separate track, usually 7 - 10 tracks. Is that too much info for audacity to handle or could there be a setting in preferences that is causing this or my computer??? Windows XP, processor is Pentium 4 2.8GHz with 1.99GB of RAM. Any help would be greatly appreciated. Thanks.

Upgrade to Audacity 1.3.13 Beta if you are not already using it:
http://audacity.googlecode.com/files/au ... 1.3.13.exe

You can check your current version at Help > About Audacity.

Check you do not have "Audio cache" enabled in Directories Preferences.

What format are the recorded files in - multichannel WAV? Or is each track a separate WAV file?

How long is each track? Ten tracks could be quite a lot to handle in terms of smooth playback and interface response if each track is very long. Were you editing fewer tracks before the problem started?

Ten tracks an hour long would take 6 GB of temporary space, then if you edit the entirety of all the tracks you are using 12 GB (and so on). So check whether you have sufficient disk space on the drive you are using for your temporary folder (see Directories Preferences for the temp folder location). Also defragment the drive that temp folder resides on.

If you change "Default Sample Format" to 16-bit in Quality Preferences that will halve the disk space requirement without any audible quality loss in most practical circumstances.

When you have two tracks edited to your satisfaction, selecting them and Tracks > Mix and Render to combine them into one track may help. If disk space is still a problem then you could try View > History and discarding undo levels.
