Introducing ACID, a break-through loop-based music production tool from Sonic Foundry. With loop-arranging and editing, ACID gives musicians unprecedented creative flexibility.
Just imagine working with hundreds of ACID's cutting-edge loops or bringing in your own audio samples to create custom music in minutes.
ACID allows you to preview any loop before adding it to your mix, automatically matching the tempo and key in real time. Click-and-drag to easily add or delete loops. ACID allows real-time changes to pitch and tempo to unlimited tracks (based on system RAM). Control the volume, pan, and effect envelopes for each track to create a perfect mix between loops. To add the finishing touches you can apply multiple real-time effects with DirectX Audio Plug-Ins like Sonic Foundry's family of professional effects plug-ins, XFX™ 1, XFX™ 2, and XFX™ 3.
To further edit loops, ACID provides quick access to Sound Forge or other audio editors. Processed audio can be directly output as .WAV files or exported as digital audio tracks. ACID is also compatible with Sonic Foundry's CD Architect and direct-to-digital audio CD programs.
ACID includes a library with hundreds of loops in many different instruments and musical styles:
Techno, Rock, Rave, Break Beat, Funk, Country, Hip-hop, Disco, Alternative, House, Industrial, Guitar, Bass, Synthesizer, Drums, Vocal, Brass, Turntable, Sound Effects, Ambient.



Additional loop libraries are available, and we're always planning to add more. They'll give you a wealth of material which you can use to kick your loop-based productions to the next level!
If you want to see and hear just what ACID can do, download the ACID demo, along with four demo songs you can play with.
