Audacity 2.0.5, Windows 8 64 bits
When recording from a cassette with Audacity, I find on listening the record that on many times a short fraction of second is missing in the music.
It is not a silent blank but like jumping over a fraction of second of music and continuing.
This is happening whatever the length of the recording (from 10 to 45mn) and of the buffer size (from 50 to 400 ms).
I even try giving an high priority to the Audacity task without result.
I returned to the cassette and verified it is OK.
I suppose it is related to writing on the disk.

you have some sofware for closing un-necessary tasks when using Audacity but they do not work with Windows 8.
