This compressor has the lowest total harmonic distortion of any plugin we have seen, including desktop units. At the heart of it is a unique envelope follower design that makes it possible to compress the signal without creating distortion harmonics. On the spectrum of compressor tone that ranges from "vintage analog" to "pristine digital", this plugin sits at the extreme end of low-noise digital clarity, but it is different from other low-noise digital designs because it doesn't use digital look-ahead. Therefore its response time is immediate, it adds no extra delay to the signal chain, and it works great for processing real-time performance effects. It uses no oversampling so there is no phase distortion or loss of high-frequency energy from anti-aliasing filters. It also uses no digital-style filters (FIR filters) and no digital look-ahead, so it adds no additional latency to the signal chain. Although it is not a model of an existing piece analog hardware, every component of its signal path is realizable in the analog domain. We think of it as a digital model of our ideal analog compressor: it could exist as an analog circuit but would be very expensive to build with physical analog electronic parts. The user interface is 100% scalable, designed specifically for iOS, so it looks beautiful at any screen size or orientation, from tiny portrait views in AUM on iPhone to the largest full-screen views on iPad Pro.

Drikus Demo Deck — four tracks, as fast as Voice Memos. For the moment a song shows up and you need it on tape before it leaves again. Record onto four tracks, overdub without losing the take, and find the song again later — even if all you remember is one line from the lyrics. Built for actual songwriting, not just voice notes - Four tracks with arm, volume, pan, mute, solo, and live meters - Per-track three-band EQ, saved with the session - Multiple clips per track, gap-accurate — silence stays silence - Precise overdub timing, compensated for your headphones' real latency, with a manual nudge for stubborn gear - Bounce all four tracks down to one, undoable until your next bounce - Export to M4A or WAV and share anywhere - Import audio from Files, or share a Voice Memo straight in - Pick separate microphone and output devices per session Find the song, not just the file Forty sessions in, "Aug 26 · Marigold" tells you nothing. Search the shelf by a word from the title, your notes, or anything the phone heard on a take you asked it to listen to. On-device transcription (iOS 26+) means nothing ever leaves your phone — it's there to help you find the song, not to write down the lyrics. Nothing leaves your phone. No accounts, no uploads, no cloud. Your takes stay yours.
