Psycho Filter lets you draw filters directly on the spectrogram and control gain and fades for surgical spectrum shaping. Pitches Brew modifies pitch and formants with editable curves for creative transposition or timbre reshaping. Stretch Life stretches and compresses audio while preserving pitch, with real-time visual feedback. All three apps are free on the App Store and run natively on iPad and iPhone, bringing spectral processing tools that were previously desktop-only to your mobile setup.
For iPad music production, you open Psycho Filter to carve out problem frequencies in a vocal take, use Pitches Brew to shift a melody into a new scale without artifacts, or stretch a drum loop in Stretch Life to fit a new tempo. The visual editing approach works well on the large iPad screen, and all three apps stay lightweight enough to run alongside your main DAW. They’re particularly useful for quick corrective work or creative sound design during mobile sessions where you don’t want to open a full desktop tool.
The collection brings Ircam research-grade DSP into a touch-first package with no subscriptions and no in-app purchases. The lack of AUv3 support means you can’t host them inside a DAW directly, but the precision and results hold up for standalone use. Export your processed audio and bring it back into your session manually — a small trade-off for tools at this level running free on iPad.
