Post by: c.b.taper on August 03, 2006, 10:03:44 AM
trying to transfer info to computer i have midi mia card in my older computer and when i try to transfer it starts out fine. eventually it sounds like it is running on slow on playback. when i listened to the tape it sounds fine . what is going on ?

Does the speed start off fine and then gradually slow down?  Or does it start fine and then there's a specific point in time at which it jumps to slow?  Or is it slow the entire time on the PC?  If the last, sounds like a sample rate mismatch between the WAV header and the data.  You should be able to use a WAV editor to change the WAV header's sample rate to match the data.  Note:  this is -not- resampling, and should take place nearly instantaneously.  If it takes time, then you're resampling, and that's not what you want to do.

If the either of the former...dunno what to say.

That's really strange.  Does it sound clean when it starts slowing down?  In other words, it's not full of clicks/pops or the stuttering that you see when the computer can't keep up w/ the data it's trying to record?

master tape plays great i tryed to transfer to soundforge 7.0 with a mia/midi card in my desktop. tape is 48 sample rate. soundforge is set to recode to 44.1. when i go to playback on soundforge or goldwave there are spots that are "slow" otherwise the recording sounds fine. i have no idea whats going on and running out ideas to transfer dat to my computer digitally of course.

I beleive that you will have to record the music at 48K and at a later time downsample to 44.1K.  I know when I forget to make sure the sample rates are set properly, I will get speed problems.  i hope that is your problem.  Good Luck.
