Audacity Forum

Hi,
I used a 2 channel interface to record 2 tracks using a quitar and drums.
I played it back and it sounds good.
I then added a 3rd track of just vocals and when I play back all 3 tracks at the same time, my voice is either too fast or I sound like a kid.
Any suggestions on how to fix?

2 channel interface. What and by whom?

Your overdubbed voice is higher pitch or literally too fast -- you get to the end of the song before the backing track does?

Can you tell if the backing track is running at the right speed? Nobody is shocked to learn that sound cards cut corners in order to be cheap. One of the things they can do is have separate data timers for record and playback. You never notice timing differences until you precisely and directly compare them like you're doing.

Try this. Start recording and perform a rim shot. Perform another one exactly three minutes later. Play back the "song." I'm betting it's nothing like three minutes long. Measure the song in Audacity. If the song in Audacity is exactly three minutes long, then the playback system is fried. If Audacity matches the playback duration, then the record system is fried. If all three are different, then the sound card is really fried. In all three cases you need a new sound card.

There could still be an exotic software problem, but I'm going with the hardware.
