Bringing desktop-grade audio editing, recording, and on-device AI together, SoundLab is a powerful sound editor that lets you edit audio, clean up speech, separate vocals, and mix up to 16 tracks. SoundLab is more than an audio editor. It is built for the ideas, quick edits, and unexpected creative needs that come up during music and podcast production, so you can start creating anytime, anywhere on your iPhone or iPad. We won't claim SoundLab replaces a desktop DAW. But it is a serious mobile production tool for the moment the idea arrives and you don't want to open a computer — or wait thirty seconds for a desktop DAW to launch. Precise Multitrack Audio Editor • Mix up to 16 tracks with gain, pan, mute, and reordering. • Copy, cut, paste, trim, insert, replace, split, duplicate, join, move, and more—with unlimited undo/redo. • Zoom smoothly for millisecond-level selections. • Loop any range while you work. • Draw non-destructive volume curves for fades and ducking. • Record overdubs directly into your project while monitoring playback. AI Vocal Separator & Vocal Remover Separate vocals and instrumentals, create acapellas, or make backing tracks with the vocal remover. Karaoke Mode preserves fuller accompaniment. AI runs locally: no uploads or server queue. AI Stem Separator Split into four stems—vocals, drums, bass, other—or six with guitar and piano. Preview and balance parts, then export a mix or individual stems. AI Noise Reducer & Audio Enhancer Use AI Noise Reducer on recordings or AI Noise Suppression on selected audio. EQ, compression, de-essing, normalization, amplification, and Bass Boost provide enhancement for voice and music. 25+ Selection-Based Effects Apply 25+ effects to any waveform range, including AI separation and noise suppression, 10-band EQ, Reverb Pro, Tape Delay, Compressor, Change Pitch/Tempo, Fade In/Out, Phaser, Reverse, Silence Remover, and more. Master Effects Master Effects run in real time on the mix bus. Adjust tempo, pitch, reverb, and EQ while previewing, then export alternate versions without changing tracks or clips. Audio Recorder • Quick Recorder: Capture ideas with your chosen input device. • Recording Studio: Monitor your mic, set input gain, use a limiter and reverb, and record over a backing track—with or without it in the saved mix. • Use compatible external microphones and audio interfaces recognized by iOS. Import, Create & Organize • Import from Files, Music Library, other apps, or Wi-Fi; extract audio from video. • Convert text to speech and add, insert, or replace audio in your project. • Sync audio with iCloud; archive and restore projects through iCloud, USB drives, or external storage. • Use Video Composer to mix audio with video and create soundtrack videos. Flexible Export Export AAC, ALAC, MP3, FLAC, or WAV with selectable channels and sample rates, plus high-bitrate and lossless options. Add metadata and cover art in supported formats. Save to Files or iCloud, share, or export a ringtone. SoundLab is perfect for: • Music lovers and independent creators • Podcast and voice-over producers • Music students and teachers • Especially for users who are familiar with Audacity or Audition SoundLab Pro SoundLab Pro unlocks all Pro features.

This is an AUv3 compatible Multi-Track Recorder plugin specifically designed for AUM and other DAW's that don't support audio recording capabilities. MultiTrack can be used for a host of purposes such as a tool for recording and layering audio for export to other DAW's , creating that perfect loop for other third party applications or recording vocal sessions to accompany you in AUM. Its uses are endless. It features the ability to record up to 8 mono or stereo audio tracks per instance, with the ability to run multiple instances under the control of your host DAW. MultiTrack has the ability to run standalone using it's own transport or synced to a host which allows synchronous control of multiple instances. MultiTrack supports various recording modes including the ability to set punch in and out points for sample accurate recordings. Press the Host Sync in order to the advantage of the hosts transport controls or enable the remote button to enable host recording controls (great for NS2). Use the Audio Pool window to quickly and easily import, export and perform mix-downs of audio clips. Quickly and easily move audio files using drag and drop to the time line or between the audio pool and the Files App. Imported audio is automatically converted to the projects sample rate. The audio pool also features the ability to copy and paste audio directly from the iOS pasteboard as well as preview and manage your data. An intergrated 8 channel mixer allows you to control the level, pan and effect send levels. Although AUM allows some great routing options for third party effects, MultiTrack also includes an extremely CPU friendly beat synced delay and reverb which can be used where recording pre-effected instruments is not an option. MultiTrack allows per clip volume level as well as being able to control start and end cropping and fade in/out on a clip by clip basis. All these operations are quick and easy to make using the touch screen alone. Also included is the ability to perform operations such as splitting, normalising, reversing and time stretching of audio clips all with a multi-level undo built right in. A comprehensive set of selection, copying and duplication tools make editing a breeze. Each track has it's own mute, solo and metering which can also be used to monitoring incoming signal levels. Finally you have the ability to mix down a selected range of your song or create perfectly looped samples for use in other DAW's , samplers and drum machines such as DigiStix. Features: ○ 8 tracks per instance. ○ Mixer with level, pan and effect settings. ○ Mix mono or stereo clips on a track. ○ Built in CPU friendly delay and reverb. ○ Multi-level undo function. ○ Loop play and record modes (when not synced to host). ○ Mix-down facility. ○ Cut, copy, paste and duplicate clips. ○ Ability to sync to host tempo. ○ Metronome with count-in. ○ Drag and drop support with the Files App. ○ Backup and Restore of individual songs. ○ Automatic conversion of imported audio. ○ Zoom mode for use when cropping clips.
