[LAU] Audacity: not good for making loops

[Kim Cascone]

I guess I must have misread the Audacity web site and the manual because 
a moderator on the Audacity Forum just enlightened me to the fact that 
Audacity is NOT an audio editor (as 99.9% of the users falsely believe) 
but an 'Editorial Production Environment Manager'! </sarcasm>

Audacity leaves *a lot* to be desired when it comes to making loops

to wit: having to hit stop or pause so Audacity can 'pick up' the loop 
start and/or stop markers that were moved during playback makes crafting 
loops very painful - I'd go so far as to say useless actually.

can anyone suggest an audio editor (on Linux) that edits loops in real-time?

thanks in advance!
