Subject:Sound Forge vs. Audio Studio issues

I have been using the "full blown" Sound Forge for a couple of years, primarily in conjunction with a high speed cassette tape player, to transfer the contents of the audio tape to computer very quickly. Once the transfer is done, the file, which has that "chipmunk" sound to it, is "decompressed" using Effects --> Pitch --> Shift. The file, which now plays normally, is then given to my requesting user.

There are times when we need to edit out and remove small portion(s) of an audio track, or the reverse, select out and retain only small portions. This is done using the standard editting tools.

My company wants to give users the ability to perform the editing function, as the number of editing requests coming in to me is increasing substantially. I believe the Audio Studio product can address that issue fine.

What I'd like to do is ALSO use the Audio Studio, if possible, instead of the "full" Sound Forge for the high-speed transfer process, primarily becauase Audio Studio is far cheaper, and in general I don't need any of the "advanced" features. So I'm basically comparing what I can do with Sound Forge and how I would accomplish the same thing with Audio Studio. I've run into problems and would appreciate some advice.

First, in Sound Forge I can select the sound card that is used by the cassette player. Audio Studio appears to be fixed with only three options; Microsoft Sound Mapper, Direct Sound Surround Mapper, and Windows Classic Wave Driver. How, if at all, do I get Audio Studio to recogninze and allow me to select my sound card?

Next, as I stated above, to "decompress" the file that was created by the high-speed transfer, I normally use Pitch-Shift. That function doesn't appear to be readily available in Audio Studio. So how do I slow down, or speed up for that matter, an audio file?

If you choose the correct sound card as the default card in Windows sound setup then that's the one that Sound Forge Studio will use.

Look for the sample rate display in the center of the lower border of the waveform display. Double-click it and type in a lower value. If you recorded at 44.1HKz with the tape running 4x, change this to 11025 instead of 44100. You can then Process/Resample afterwards if you want to, but it probably won't gain anything.

Keep in mind that if you do transfer at 4x you're losing the top 2 octaves of the frequency range. Using my example above, the highest requencies you're recording are only in the 5.5KHz range. I suppose if you're working with speach only that's fine, but that is going to affect music quite a bit.
