recorded audio track woes.

Hi, just trying to record 1 guitar over a backing track.
Baking track imported mp3. I record guitar part, all seems ok, but it's out of sync. I have tried using drag and drop and nudging. If I line up the start of the guitar part to the backing track it slowly goes out of sync again as the track progresses. Same if I line it up from the end of the section, the start will be way out.
 
Help appreciated.
 

Thanks for the welcome and response. I have just listened to the recorded guitar part alone and it's full of weird noises and seems to speed up and slow own.
 
When you say "the device you are recording through"  I have a tc  effect processor into a MI audio fast track, that connects to my usb. Which one would I change and how.
 

Use only the Fast Track and its ASIO drivers with SONAR. Don't select the mobo soundchip for anything in the Options or Preferences (you did not even mention what software you're using :o)

Check your computer to see if something is interferring with streaming audio and video. Not the best program there are others (not free) but this program is free.

And using ASIO drivers account for latency in the recording, Windows drivers will always lag a certain amount (like KS/M whatever drivers or MME drivers. ASIO are the only drivers where you hear the music and record the music and hear it all at the same time.
 

Now that you have got a working Fast Track installation running ASIO, you might want to consider changing the bit depth to 24. In SONAR both the Preferences > Audio > Driver Settings "Audio Bit Driver Depth" and the Preferences > File > Audio Data "Record Bit Depth" need to be changed.
