Hi Josh, concerning changing the speed. There are a couple of options: 1. The change speed effect, see: http://manual.audacityteam.org/o/man/change_speed.html2. The sliding time scale/shift pitch effect: http://manual.audacityteam.org/o/man/sliding_time_scale_pitch_shift.htmlYou don't actually want to vary the speed change, so you would enter the same values for the initial and final tempo changes. This second effect is much higher quality than the first effect, though it takes more processing time. David.

I am new to autdacity first of all and I use NVDA screen reader. so 1. some tapes were recorded with a 4-track tape recorder, how do I separate each stereo channel and make it its own mp3? some tapes like the old 2xl robot tape have two different things going on, like if you listen to it in your left ear you may hear a story while in your right ear you'll hear a voice asking questions and telling you to hit buttons on the robot toy. I want to separate each left and right channel into its own mp3. 2. some tapes are sped up. How do I slow them back down to normal speed? 3. and if it won't ruin quality and take too much time can I apply filters or get some tape hiss removal filters for audacity? thanks -- follow me on twitter @joshknnd1982 or facebook email joshknnd1982@xxxxxxxxx will find facebook site The audacity4blind web site is at //www.freelists.org/webpage/audacity4blind Subscribe and unsubscribe information, message archives, Audacity keyboard commands, and more...
