[ddots-l] Re: punch problem

Chad,

It sounds like a latency issue. If I'm right, you're hearing back the previously recorded material mixed with the new content you are recording. The new content is going from digital files on the hard drive being converted to audio, one conversion process. Meanwhile, the new punched in material is going from audio to digital then being played back as part of the full mix so back from digital to audio.

One way that was suggested to me for this with another audio recording program was to have the output of the prior material go into a hardware mixer and then the new material also going into the mixer, listening to both via the control room output via headphones plugged into the mixer. And of course that new content alone would be routed out of the mixer and into the recording software.

Within the software environment, without having an external mixer, then it is best to pick a lower hardware buffer size when overdubbing. And then later when mixing lots of tracks with various plug-ins, increase the hardware buffer size. In my Pro Tools rig I can have the buffer too high and hear the delay between the time I hit the guitar string and the time it comes out of the monitors. When I drop the buffer in that to 256 samples or 128 it isn't noticeable. I assume that Sonar has a similar change you can make.

Hello I didn't get an answer to this question.  This is probably my fault, I 
probably didn't ask the question the write way.
IN sonar I'm having a problem with punch ins.  When I first record a audio 
track with vocals the timing is just fine.  However When I try and punch in to 
fix a piece of the recorded audio The new punched in material's timing is not 
in line with the rest of the track.  However, When the new puched in material 
ends the rest of the original audio plays at the correct timing.  Can anyone 
tell me why this frustrating problem is occurring and how to fix it?
Thanks you very much
Chad
merry Christmas to all!
