Audio Lab

Read full description

Audio Lab is a focused tool for turning raw recordings into finished, shareable content. It is built for artists who want a simple way to produce audio without getting lost in complex workflows. You start by uploading audio or video. From there, you can shape and refine it step by step - mix, add professional effects, automation. You can record automation in real time for any effect parameter - which gives flexibility and endless possibilities for your production. You can split vocals and instruments using a stem separation feature - giving you control over each part of the sound. This opens up new possibilities. You can clean up a vocal, remix a track, or focus on specific elements without starting from scratch. Audio Lab also includes a range of professional effects. You can enhance clarity, adjust tone, and shape the overall sound directly inside the app. The goal is not to overwhelm you with options, but to give you what you need to get a clean, polished result. There are 20+ professional effects, including reverb, delay, compressors, eq and more. There are also presets for various types of sound - male/female vocals, guitar, bass, drums, piano etc. Everything happens in a simple, controlled environment - You make changes, hear them immediately, adjust. This keeps the process fast and intuitive, especially if you don’t want to spend time learning a full DAW. It works for different types of creators. Singers can record and refine vocals. Musicians can process demos. Content creators can improve audio for videos. The tool adapts to different use cases without changing how it works. There is no complicated routing or setup. No need to manage large projects or timelines. Audio Lab focuses on a single goal: take an existing piece of audio or video and make it sound better. Export is simple. Once you are done, you can export your audio or video and use it anywhere. Share it, upload it, or move it into another tool if needed. It also includes professional mastering built in - with presets for different styles and genres. It keeps things clean, removes friction and lets you focus on the result, not the process. You don’t need to think about how to produce. You just improve what you already have. You explore, listen & create - That’s the core idea behind Melodic Mind. Let music feel natural again.

Split any song into four separate tracks. Audio Editor: Stem Separation pulls drums, bass, vocals and everything else apart in one tap, so you can mute the singer for karaoke, keep the vocal on its own for a remix, or rebalance the mix until it sits right. Everything runs on your device — your audio is never uploaded. SEPARATE ANY TRACK Drop in a song and get four clean stems: drums, bass, vocals and other. Play them together on one transport, ride a fader for each, and share any stem on its own. REMOVE VOCALS FOR KARAOKE Pull the vocal down to silence and keep the band. Or keep the vocal and drop everything else for an acapella. CLEAN UP A RECORDING Take out hiss, hum and room tone with a choice of three models — they are different answers, not a quality ladder, so you pick the one that suits the take. ENHANCE A VOICE More than noise removal: a high-pass, a presence lift, a compressor and a broadcast loudness target, in three finishes for podcasts, interviews and voiceovers. RECORD ON THE SPOT Capture a take with a live meter and a peak readout, then send it straight into any of the tools. FIX A VIDEO'S SOUND Treat a movie's soundtrack and put it back, with the picture copied frame for frame rather than re-encoded, then save it to Photos. A REAL MULTITRACK EDITOR Lanes, trim, move and split on a pinch-zoomable timeline. Volume, speed, pitch, fade and reverb on any clip. Export the whole arrangement as one file. EVERYTHING IS KEPT Every recording, every clean, every separation and every project is saved automatically and reopens exactly where you left it. NOTHING LEAVES YOUR DEVICE All processing runs locally on your iPhone. No account, no upload, no server.
