High frequencies cuts

Post by yofeliz » Wed Jan 20, 2021 7:25 pm

Hello everyone.

I'm experiencing a problem in Windows 10 with Audacity 2.3.2, recording through CleanFeed.

As you could see in the attached image, sometimes the high frequencies get cut, and I don't know why.

I thought I could be CleanFeed, but I happens from time to time no matter what I do.

Any thougth would be much appreciated.

I don't know anything about CleanFeed, but maybe those frequencies have been cut/limited somewhere else...

Given that there is such an abrupt cut-off, my guess is that it's to do with the audio sample rate being lower than the sample rate that Audacity is recording. In digital audio, the frequency range is limited to half the sample rate.

Thank you, dear friends.

Sample rate is correct; I use the same configuration in another computer, and it's working with no issues.

Thinking about that maybe it is a driver problem, I tried reinstalling the Audio driver, but didn't work.

I'm sure that must be something in that computer... maybe an I/O issue? :\

Any idea will be welcomed :)

Do you mean that you are recording from CleanFeed with Audacity?
The CleanFeed website says that CleanFeed has "Built-in recording", so I don't understand where Audacity fits in.
