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.

Verdict
The clearest difference is price: SoundLab at Free against Dahlia Delay's $1.99. SoundLab also leads on update cadence (weekly vs every 5 months) and ratings volume (15K vs 6). Dahlia Delay's advantage is in-app purchases (none vs 3) and review sentiment (88% vs 65%). On ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
SoundLab is free to download; Dahlia Delay costs $1.99 up front. SoundLab sells 3 in-app purchases, starting at $3.99 per month. Dahlia Delay asks for nothing beyond the download.
SoundLab holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: SoundLab has 15K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 88% of Dahlia Delay's written reviews are positive against 65% of SoundLab's, so the app with the better star average is not the one people write more warmly about.
Dahlia Delay ships an update every 5 months, SoundLab weekly. The most recent releases landed on October 29, 2026 and November 2, 2026 respectively.
