Description

from Sergey post:

I disabled the onboard sound card and connected USB speakers and USB microphone.

The applet works perfectly.

I have recorded 2 files with a cheap Logitech USB mic.

When I try to use the studio mic "Snowball" I see the same problem in the applet as I see in Audacity: the recorded audio is twice slower and lower in pitch than my voice.

To fix this, Audacity lets you adjust the sampling rate.

I am not the only one who have this problem with Snowball in Linux:

That is sad, because Snowball's sound quality is much better than of any consumer microphones.

I guess Linux will have to fix the bug of incorrect sampling rate detection.

Or we may try to add a manual sampling rate adjustment into the applet like Audacity does.

Or, probably the easiest, record it in Audacity.

I can narrate a book into Audacity and then split it with the Automated Segmentation.

my reply:

I thought of doing this programatically (i.e. letting the system test the audio card until it finds a supported sampling rate), but I guess this is a use-case for letting users override it in a preferences tab.
