Acid Loops – Royalty Free ACIDized WAV Sample Loops

Acid Loops are royalty free ACIDized WAV sample loops embedded with tempo, key, and beat-slice metadata so they automatically stretch to your project’s BPM and key without losing audio quality. The ACIDized WAV format — originally developed for Sonic Foundry’s ACID Pro — has become the universal standard for loop-based music production across every major DAW.

Universal DAW Compatibility for ACIDized WAV Files

Every ACIDized WAV loop in our Acid Loops library is tested to work in ACID Pro, Pro Tools, Ableton Live, FL Studio, Logic Pro, Cubase, Studio One, Reason, Reaper, Bitwig, Cakewalk SONAR, GarageBand, and any hardware sampler that accepts standard WAV audio. Because the tempo and key data lives inside the ACIDized WAV file itself, you can drag, drop, and the loop instantly conforms to your session — no conversion, no time-stretching plugins required.

Professionally Produced ACIDized WAV Loops

At Soundtrack Loops we’ve been crafting ACIDized WAV sample libraries since 2004. Every Acid Loop is recorded, sliced, tuned, and mastered by working producers and sound designers to loop seamlessly and sit clean in a mix. Whether you’re producing hip hop, EDM, cinematic, house, trap, ambient, rock, or world music — our ACIDized WAV loops deliver broadcast-ready sound out of the box.
