Having recently checked in with two of our favorite Sony products, Vegas 8 and SoundForge 9, I thought it time that we check in on Sony’s Acid product, which has recently arrived at version 7. A percent-off email that showed up on Black Friday provided me with further encouragement to upgrade. Moreover, we haven’t checked in with Acid since version 3 way back in 2002, and the loop-based production tool has changed a great deal in six years.

For one, Acid has added full-blown audio recording and editing to its arsenal of looping tools. And like its sibling SoundForge and Vegas, Acid 7 now has a full-fledged mixing console interface. I’ve been a fan of Acid in the past for its ability to time-stretch and -shrink music files for concert promos, with few or no audio artifacts. Acid 7 does this job with even fewer artifacts than before thanks to its use of new algorithms from Germany-based Zplane Development.
