I've been working on the same thing for some years, but think of it as speed listening. Time stretching has also been applied to video by the U of Utah a few years back, but did not catch on, for use in viewing lectures. Here's a gist of what I've got that adds to what others have said: For several years I've sought software that increases the speed of podcasts and corrects the pitch to eliminate the chipmonk effect. Windows Media Player does the best job on a computer and Audacity will slowly convert a file using a 2-step process. Just this year FasterAudio.com and MP3 Speed Changer from http://www.crazyboomerang.com/ began offering software that will batch process audio files with pitch-corrected speeds over 200%. MP3 Speed Changer, at $20, is the cheapest and also the most stable of the two. However, I don't think it is quite as good as Windows Media Player. MP3 Speed Changer is adequate for me and the developer has done past work to produce improved versions, so future versions may occur that offer better results. Speeds faster than 50% begin to introduce artifacts using MP3 Speed Changer, so I batch files to 50%. The MP3 speed changer can be used for greater speed with less chipmunk effect, then.

I don't have as long of a commute as I did when I wrote this but I still have to catch all of the Totally Rad Shows ( http://revision3.com/trs ). :) FYI, I just set this up again on my new PC and it still works great with current foobar2000 versions (v0.9.6.8 at least).

Thank you! Thank you! I listen to all of Leo's TWiT podcasts and with my new job it's getting impossible for me to keep up. I'm sure this will be the answer I've been looking for. I also forwarded this to Leo's Twitter account and Facebook page hopefully we can get him to recommend it on his podcasts. Thank you! Thank you! Thank you!

Update: You can easily unDRM the files by using free2me and drmdbg. A small GUI for this has been created called unDRM.net.exe. Note: Only works if you can actually play the files (i.e. you have the license). OK!

Would be nice to not have to manually rename or save to different folders. Thanks tho, real time saver!!
