ToneBoosters ReelBus is a top-quality, authentic, versatile and accurate magnetic tape simulation plug-in bringing warmth and excitement of tape to your iOS or iPadOS device!

Instant gratification from 80s compact cassette sound to professional 30 IPS studio recorder simulation. Sweeten your mix with a touch of tape hysteresis, saturation and compression. Create that 'Boards of Canada' sound by adding a tad of wow-and-flutter. Top it up with tape flanging, echo and tape start/stop effects.

The ToneBoosters ReelBus app captures the microphone (or external sound card) input and processes the signals in real time. To use it as a plug-in, use an AUv3-compatible host app such as Steinberg Cubasis, Apple Garageband, Audio Evolution Mobile Studio, Auria, AUM, or others.

The tone I’ve been looking for

There are only a few tape effects available on this platform but so far only this one offers what I need. Excellent sounds and so many options to choose from. Well designed UI and so versatile. ToneBoosters have really designed some high quality effects and at the price offered they are an absolute no-brainer. I’d have paid twice the price for this effect. Well done TB. I’m off to buy the EQ now.

The Best Tape Emu in iOS

ReelBus can nail tape saturation, compression, and the BOC/LoFi wobble better than just about anything else. (Most other “tape” sims in iOS only give you a static wow/LFO in place of random instability.). It’s also great for general tone polishing and master bus “glue”, especially with the SSL style compressor in Auria Pro.

This program is so good that it converted me to using it in Reaper on desktop as well. 5 stars, no question.

ToneBoosters can do no wrong.

These plugins are the real deal. This one in particular can be as subtle or drastic as you want it. And the added tape delay and stop effects are really lovely as well!
