sound speed control and other misc editing

[Lockup]

im looking for an audacity-like program thatd let me cut a song up in small bits(or put bookmarks etc) that has speed control(with decent sound quality)...i thought audacity had that but apparnatly it hasnt implemented the speed thing yet, any suggestions?
for now im stuck with xmms's sndstretch plugin, which gives nice results for the speed but i cant set bookmark locations and really cut it up etc
thanks in advance
