## Description

Sonolab is a complete music toolkit for musicians, singers, and producers — built entirely on-device with zero data collection.

TUNER
Real-time chromatic tuner with configurable concert pitch (A4 from 432 to 444 Hz) and a built-in reference tone generator. See your pitch, cents offset, and nearest note instantly.

METRONOME
Precise metronome with tap-tempo detection and visual screen-flash sync for loud environments.

RECORD
Multi-track recorder capturing studio-quality audio (32-bit float, 24-bit, or 16-bit WAV). Organize takes into projects, browse your library, and share in MP3, AAC, or lossless WAV.

ANALYZE
Drop any song in and get deep, section-level analysis: key detection, BPM estimation, tuning drift, loudness mapping, frequency spectrum, spectral heatmap, melodic range, and onset density — all computed locally.

STUDIO
Separate any song into vocals, drums, bass, and other stems using the HTDemucs v4 neural network — running entirely on your device. Then mix with a full effects chain: reverb, delay, 5-band parametric EQ, compressor, and pitch/tempo control. Export your mix in your preferred format.

PRIVACY FIRST
No accounts. No tracking. No uploads. All audio processing happens on your iPhone. Recordings stay in your Documents folder and are included in your iCloud backups — nothing leaves your device.
