FIELD KIT is an audio playback instrument built for turning recorded sound into evolving texture, rhythm, and atmosphere. Load an audio file and create up to four independent playback windows across the recording. Each window can move through a different section of the source with its own playback speed, direction, crossfade, drive, filtering, level, and pan. Use FIELD KIT to pull overlapping textures from long field recordings, transform environmental sound into ambient beds, create asynchronous loops, or find entirely new material hidden inside a recording. Three modulation sources can be routed independently across the playback windows, allowing parameters to drift, pulse, and evolve over time. Features include: - Up to four independent playback windows - Forward, reverse, and ping-pong playback - Variable playback speed - Adjustable loop crossfade - Drive and filtering per window - Independent level and pan controls - Three routable modulation sources - SPLICE for working with multiple audio sources - Save and recall .fieldkit files to share across platforms - Internal recording in Standalone mode - Standalone app and AUv3 Audio Unit - Host transport support in compatible AUv3 hosts FIELD KIT was designed around a simple idea: a recording doesn't have to be played from beginning to end. It can be a place to explore. ## Key features - Up to four independent playback windows - Variable playback speed and direction - Drive and filtering per window - Routable modulation sources - Save and recall .fieldkit files - Standalone app and AUv3 Audio Unit ## Chart rankings - #27 in Top Paid · Music (US App Store) ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/field-kit-playback-engine/id6810484807/reviews.md ### 4/5 — Terrific audio playground *2026-09-23* Really great idea: bring up to four audio recordings/samples into the app, then cut/dice/loop/edit them to make a soundscape. You get control over playback speed and direction, volume/pan etc, plus there's a really great section where you can use an LFO to control the parameters during playback so you can get nice auto-panning, flutter effects and so on. Two things missing: no ability to add AUv3 effects to the four channels. This is a big one for me and it limits what I can do to create ambient effects. You can load it in AUM but then the effects you add would be global across all four slots. Second: no ability to record and capture audio within the app, so you can't capture a space spontaneously out in the field. Bizarrely there's a record button in the app but it doesn't record, it just exports your current audio. ### 5/5 — First App - Fantastic *2026-09-23* First app from this developer and it’s a sound designer’s dream sample manipulation tool. I’ve spent hours with this and it continues to impress me. ## Frequently asked questions about FIELD KIT Playback Engine ### What is FIELD KIT Playback Engine?
