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.
MojoDeck
This app emulates vintage cassette recorders, adding warmth, instability, and unique character to digital audio. It offers granular control over tape emulation effects like wear, saturation, and wow & flutter, with two distinct tape formulations for diverse sonic textures.
- Vintage tape emulation
- Tape wear and saturation controls
- Wow & flutter effects
- Adjustable tape speed
- Two tape formulations (Ferric, Chrome)
- Analog-style VU meter
- Multiple export formats

MD-1 is a cassette-inspired recorder for iPhone built for people who miss warmth, instability, and happy accidents. It combines vintage tape behavior with modern recording workflows, minus broken belts, dirty heads, and finding out your favorite cassette got eaten. TAPE CHARACTER CONTROLS Five sliders. Five ways to ruin perfection. Push the input gain into the red. Add Tape Wear for softened highs and tired old cassette energy. Drive Saturation for harmonic grit and glue. Introduce Wow & Flutter for subtle instability and capstan wobble. And change Tape Speed from 0.5x to 2.0x, with pitch following along as real tape would. Digital audio has spent decades trying to eliminate these things. We put them back. TWO TAPE FORMULATIONS Ferric (Type I): warm, bass-heavy, beautifully imperfect. Chrome (Type II): brighter, cleaner, slightly more civilized. Different EQ curves. Different saturation. Different personalities. RECORD WITHOUT THE DRAMA Punch in anywhere without losing the rest of your take. Monitor your input before recording. Watch your levels on a proper analog-style VU meter. Keep track of time with a mechanical tape counter because honestly… DAW timelines are boring. EXPORT YOUR WAY AAC. WAV. Dry. Saturated. Clean-ish. Completely cooked. Send recordings anywhere via AirDrop, email, SoundCloud, or whatever app your music disappears into next. BUILT LIKE A PIECE OF GEAR Portrait for quick captures. Landscape for full control. Supports USB audio interfaces, microphones and external gear. Double-tap Tape Speed to snap back to 1.0x. And yes, the reels spin faster when you speed up the tape. We know that doesn’t improve the sound. That’s not why we added it. MojoDeck MD-1 The best cassette recorder since the death of cassette recorders.

Verdict
The clearest difference is price: MojoDeck at Free against Mix Bus Compressor's $5.99. Mix Bus Compressor's advantage is rating (3.9 vs 3.0) and ratings volume (8 vs 1). On ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
MojoDeck is free to download; Mix Bus Compressor costs $5.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Mix Bus Compressor holds the better App Store score, 3.9 against 3.0. That said, the two scores are not equally well evidenced: Mix Bus Compressor has 8 ratings behind it against 1, so its average is the more settled of the two.
