thx for clearing up the question I had regarding the Vocal Isolation frequency cap at 24khz. I can now make use of that feature a little more accurately.
next question…
can you think of any reason why the program doesn’t want to process an audio file (stereo) that is more than 50mins long?
When I try to make use of the Vocal Isolation option more often than not I’m working with an audio file that can be more than 90 mins long, the program doesn’t want to process the entire file in one pass. I have to do the first half & then the last (two passes) to complete what I’m doing. If the file is more than 2hrs I have to split the process into three passes.
Does Audacity have a cap on the length the file can be for processing?

Some Nyquist plug-ins retain audio samples in RAM. As Nyquist is 32-bit, it is limited to 2GB of RAM. 50 minutes of stereo, 32-bit float, 44100 Hz sample rate is about 1 GB. If a plug-in retains 2 copies of the audio, then 50 minutes will be about the limit.
This is not a limit for all Nyquist plug-ins, only those that fail to release samples as they process.
Built-in effects should not have this problem and should be good for up to 12 hours of audio. All bets are off beyond 12 hours, though some effects may be able to handle much longer, if you have sufficient disk space.
And past that you’re not doing audio production and editing anymore. You’re doing surveillance and industrial manufacturing. Out of our league. There are some very nice software packages for that complete with sticky time stamps and auto archive.
I’m using a 64bit win7 op/sys, still using Audacity 2.3.3, seeing at the program is a 32 bit application can the program NOT access all of the available ram that is plugged into the motherboard? (16gig).
Having to multi pass a large file doesn’t bother me, at least now I understand what’s happening, the program doesn’t crash, it was just aborting the operation approx half way thru the procedure.
