Hi,
is there a way to import more than 16 channels as raw data?
I'm trying to recover a 40 channels aiff file that was not closed
properly...

Any other suggestion about how to do that?

thanks,
josé

This list is specifically for questions about the Nyquist programming language as implemented in Audacity. For general help questions please subscribe to the audacity-users list:

Import Raw Data is hardcoded to 16 channels maximum and can only work on one file at a time. If you had 40 tracks open in Audacity and you are using Audacity 1.2.x then the data is split into small .au blockfiles, alternately arranged per channel. The first .au file (for example, b00001.au) in the data folder will be the first blockfile for channel 1, b00002.au the first blockfile for channel 2, b00041.au the second blockfile for channel 1 and so on. Therefore you need to try the Crash Recovery utility to recover these files so they are sorted correctly:

I don't  know if Audacity Recovery Utility supports recovering 40 channels, the command-line version only supports 16 channels. But you can always sort the .au files into subfolders for say 10 channels per folder and work on those separately.

If you are using Audacity 1.3.x it "should" recover the project automatically when you restart.
