The best audio editor. Pull a song apart into six clean stems — without it ever leaving your phone. AI STEM SEPARATION Vocals, drums, bass, guitar, piano and other, separated in a single pass. The model runs on your iPhone, so nothing is uploaded and there's no limit on how many times you separate. Want the instrumental for a cover, just the drums, or the bassline for a remix? It drops straight into the editor when it's done. Video too: import MP4, MOV or MKV and the audio gets pulled and split the same way. MULTITRACK EDITOR Cut directly on the waveform. Every track has its own volume, fades, speed, pitch, reverb and EQ. What you hear is exactly what you export. Up to 50 steps of undo. 15 TOOLS Convert · Trim · Vocal Remover · Video Vocal Separation · Extract Audio · Merge · Speed · Reverse · EQ · Denoise · Pitch · Record · Volume · Silence Remover · Compressor A few worth calling out: • Speed 0.1x–100x with pitch preserved — play a lecture at 3x and the voice stays natural • Loudness normalization at −14 / −16 / −23 LUFS for streaming, podcast and broadcast • Silence Remover trims the dead air out of long recordings • One-tap ringtones, exported straight to M4R FORMATS 21 formats in and out: MP3, AAC, WAV, M4A, M4R, FLAC, AIFF, CAF, WMA, OGG, AMR, DTS, MP2, WV, OPUS, MKA, TTA, VOC, PCM, ADX, AC3. Sample rate, bitrate, channels and volume are all adjustable. IMPORT Files, videos from Photos, audio shared from other apps, or drag files over Wi-Fi after scanning the QR code. Select several files and send them all to a tool at once. EVEN FASTER Shortcuts and Siri: convert, trim, change speed or volume, reverse — just ask. Separations keep running when you leave the app. Your pocket audio studio.
