I apologize that this request for information has fallen through the cracks.
As I mentioned, you can, if you want, speed up playback of audio files. You can do this with individual files using Studio Recorder, and with Goldwave and Sound Forge you can process one file at a time or a batch of files. I do not have Sound Forge 8 which has batch conversion built in, so I'll concentrate on Goldwave 5.x which I do have and know how to use. In order to batch process files using Goldwave, you first have to establish a preset for the speed you want to attain. The dialog for changing speeds on sound files is called Time Warp, and it is off the Effects menu. the quickest way into it is alt-c, w. I can't remember which presets come shipped with the program and which I've made. For our purposes, we'll make a new one. Goldwave has three ways to speed up playback. the one you want to use is Similarity. It takes a lot of processing power but seems to me to give the best results. the dialog has three tabs, one for each of those procedures. When you are focused on the list of presets, first down arrow to select the preset named '200 per cent via Similarity." (I'm almost positive that preset comes shipped; modifying it as needed is the easiest way to get our results.) There are three settings to adjust. We'll move backwards through the dialog to get to them. Shift-tab once to get to the 'search range.' chris, the author, recomments 5 to 10; I use 10. shift-tab again to window Size. For voice, he recommends 20 to 30; I use 30. Shift-tab twice, to get past the tabs for the three algorighms, and you come to the Specify New Relative Change dialog. Here you'll specify a percentage. Let's say we want a 75% increase, we would specify 175 per cent. (If you shift-tab once more, you can change the dialog so that you input an exact length, not a percentage.) Once these values are set, tab forward to the combo edit box containing the presets and type in a name for the new one you've created. Tab to the Add Preset button and hit space; henceforth, it will be part of the available stock of presets. You can, as with all these dialogs off the Effects menu, tab once more to preview your work on an open file; tab once more to the stop button to silence the preview. Now you've got at least one useful preset, and with it you can speed up playback of open files individually. to do more than one at a time, we need the Batch Conversion utility, alt-f, b from the file menu even if no files are open. Here, you land on the Convert tab. Tab once, or alt-a, to open the Add Files dialog. Add one or more files and hit enter when done. You can repeat the process as many times as needed, and review the list of files as it grows if you want to. In here you can also hit alt-d to add a folder. Once all files have been added, tab until you hear 'Convert Tab,' then right arrow. this puts you on the Process Tab, where we'll tell the program what effect(s) we want to add to have applied to the batch. Tab once to the Add Effect button and hit space. You are placed on a tree view whose items correspond to the items on the Effects menu. Since we want Time Warp, hit t. Once time Warp is highlighted, hit right arrow to expand the branch. Now magically appear all the presets that exist for time Warp. choose the one you want and hit enter. You'll see in the list of effects that it has been added. Note that if you have different combinations of operations you want to perform on files, for example, some files you'll play faster than others, you can avoid having to venture into the Process tab again by setting presets on the Convert tab. that way, you will simply add the desired files, choose the desired preset, and hit alt-b to press the Begin button. More can be done in this dialog, but this covers how to use it to speed up playback on multiple files. I hope this has been clear.
