Audio tape transforming to computer and adjust the playing speed

[luojuan]

Dear all,
I have a audio tape recorded when the recorder was at low battery
so when played it sounds funny. Now I want to digitize this tape
in fact this is just a human conversation. I have a River past
audio capture installed on my computer but it can not change the
speed of playing.
I am wondering how can I make the sound normal while recording it.
Does anyone have any suggestion on that?

Thanks a million!

Play it back on a machine with varispeed. Get a handheld tuner and set
the speed by ear and with the tuner.

In this case, since the tape speed is wrong, he'd want to alter both speed
and pitch. Goldwave will, I think, do that. Or, as Scott suggests, find a
machine with varispeed and play it back on that; you'll have to adjust by
ear, since there's no music to tune to (you said this was speech).

Peace,
Paul

Dear all,
Thanks for your suggestion!
I am using the goldwave 5.0 at this time as you suggested.
I found it can change the playing speed but can not record
the sound after the playing speed altered is that right?

Thanks!

Or feed the squarewave output of a function generator to your wordclock input and varispeed by adjusting its frequency...

Sure you can. Just use the analog outputs.

I don't know about your system but my 10 year old Sound Tools can destructively
change speed/pitch
