hi there
I’m trying to record myself singing, multitracking myself to make up different parts of a chorus or choir.
The problem is, whenever I sing long note, something weird happens when I play it back
after a second or two, the quality and sound level of the note degrade, and it gets a sort of echo; when I stop the note, the ‘echo’ continues for a short time, but quickly fades away
it is almost as if audacity is trying to filter it out, after deciding it is not supposed to be there. I have searched through the preferences more than once and not found a solution there
I am using a mic attached to a headset. I do have a condenser mic, but have no preamp with which to boost its sound, so I can’t use it just now.
If you can help, I would be very grateful 
Duncan
