As an artist and musician, it can sometimes be difficult to capture that great idea. Complex recording equipment and software can take you out of the moment. Multi-Tracker is a minimalist, close-at-hand tool for recording, mixing, and mastering music and audio. Use your connected audio equipment, or the microphone, speaker, and headphones on your device, to create beautifully layered multi-track audio recordings. Add equalization, reverb, delay, compressor, and limiter, then master (render) your mix to a stereo audio file for sharing and distribution.
