TS

ircamLab's TS audio editor is exceptional, especially if you'd like to take recordings and mutate them into something wildly different than what they once were. Also fine for simple trimming, etc. Time-stretch is beautiful, nearly perfect; none of the typical artefacts normally found in lower-quality time-stretching. The spectral effects are equally beautiful and quite smooth.

Fantastic audio editor from Ircamlab with state-of-the-art features for editing, sound design and remixing. The time-stretching quality alone is worth the price and is the best I've ever heard. Can't recommend this enough.

If you understand French, there's a great video overview by the designer which does it justice.
