About this app

This app transforms your iPhone into a powerful audio processing tool, recording hub, or portable amp, allowing you to amplify any connected audio input (for example USB-C guitar pedals, USB-C to 6" cables, bluetooth headphones, etc.) and route it to your preferred output device, including built-in speakers, external USB audio interfaces, AirPlay, and Bluetooth. (Please note: wireless inputs and outputs will introduce latency) Enhance your audio signal with a suite of built-in effects, including independent pre- and post-gain stages, noise gate, distortion, reverb, and delay. Fine-tune your audio with precision using the integrated 6-band equalizer, featuring customizable frequency band types and adjustable octave widths. The app also offers flexible signal chain management, enabling you to reorder effects (including the EQ) within both gain stages to achieve your desired processing flow. Finally, the app also offers a metronome and tuner functionality which can be used to practice and set up instruments. The metronome feature can be used without selecting an input. As with all my apps, this one is completely free to use, with no ads, no trackers, and no hidden costs.
