ASAP apps on iPad Free: Psycho Filter & Brew

ASAP apps on iPad from IRCAM are now available free, providing iPad-native versions of the ASAP suite. The release brings three apps — Psycho Filter, Pitches Brew, and Stretch Life — to the iPad. Psycho Filter enables drawing directly on the spectrogram for spectral-domain manipulation, Pitches Brew provides pitch and formant controls for transposing and reshaping sound, and Stretch Life offers pitch-independent time stretching.

Each iPad app is standalone, replicates the desktop feature set with multi-touch controls adapted to the iPad interface, and supports convenient file transfer options such as AirDrop. The announcement was published on March 19, 2026, by Peter Kirn.

Psycho Filter provides spectral-domain interaction through a visual spectrogram interface that accepts drawn input for direct manipulation of spectral content. The app presents tools for shaping sounds by working inside the spectrogram, enabling users to edit spectral material through touch gestures and drawing. The design emphasizes interaction in the spectral domain and integrates the spectrogram as the primary editing surface.

Pitches Brew exposes pitch controls and formant controls intended for transposing and reshaping audio material. The controls allow adjustment of pitch relationships and formant characteristics to alter timbre and perceived pitch independently. These controls are presented in an interface tailored for touch operation on the iPad.

Stretch Life implements pitch-independent time stretching as a dedicated capability for changing duration without altering pitch. The app offers time-stretching functionality that separates temporal modification from pitch content, enabling tempo changes while preserving pitch information. The control layout is adapted for the iPad touch environment.

Each iPad app is delivered as a standalone application that reproduces the desktop feature set and adapts multi-touch controls to the iPad interface. The implementations include multi-touch gestures and controls designed specifically for the iPad form factor, and the apps support convenient file transfer methods such as AirDrop for moving audio files. The iPad interface adapts desktop features into touch-native controls without introducing desktop-only dependencies.

The iPad release includes three distinct applications within the ASAP family: Psycho Filter, Pitches Brew, and Stretch Life. Each application is presented as an individual, standalone app with its own focused toolset and touch-adapted interface for use on the iPad. The apps are described as implementations of respective ASAP capabilities, delivered separately rather than as a single combined program.

Psycho Filter is presented as a spectral-domain editor that uses a visual spectrogram as the main interaction surface. Users can draw directly on the spectrogram to manipulate spectral content, applying edits and shaping sounds through touch gestures and drawing tools. The app prioritizes working inside the spectrogram for direct spectral interaction.

Pitches Brew centers on pitch manipulation and formant control, providing interfaces for transposing audio and altering timbral formant characteristics. The controls enable adjustment of pitch relationships alongside formant shaping to change perceived pitch and timbre within the app.

Stretch Life focuses on pitch-independent time stretching, allowing duration changes without altering pitch and offering controls adapted for the iPad touch environment.

The ASAP suite is distributed for desktop as plug-ins for macOS, Windows, and Linux, and the plug-in versions include ARA support. IRCAM has released separate iPad-native ASAP apps as standalone applications rather than plug-ins. The article indicates that the iPad implementations reproduce the desktop feature set with controls adapted for multi-touch and the iPad interface. These distribution differences separate host-based plug-in workflows from the touch-focused iPad workflows.

Integration features highlighted in the article include support for transferring files to the iPad using AirDrop and storefront availability via the Mac App Store for the iPad-native apps. The article distinguishes the desktop plug-in availability from the standalone iPad release and notes ARA support specifically in the plug-in versions. The coverage frames these items as integration and distribution details rather than technical specifications.

The article presents the desktop plug-ins and iPad apps as distinct distribution methods and highlights integration points such as ARA support for plug-in users and App Store availability for iPad-native apps. It does not include low-level technical specifications such as specific plug-in formats, minimum operating system versions, or detailed host-DAW compatibility matrices. The available sources do not provide this information.

IRCAM Forum’s Pierre Guillot has announced the availability of three ASAP apps for free on the iPad, as reported in the source. These applications are adaptations of the platform’s desktop suite designed specifically for multi-touch interaction on iPads.

According to the source, these apps provide the same comprehensive feature set as their desktop counterparts, utilizing intuitive controls that enhance the user experience.

The full ASAP suite also remains available for desktop operating systems like macOS, Windows, and Linux, where it functions as a series of plug-ins. The report from IRCAM Forum focuses on expanding accessibility by offering these powerful audio transformation tools on a mobile platform without charge.

Stretch Life implements pitch-independent time stretching for changing duration without altering pitch.

Each iPad app is a standalone application that reproduces the desktop feature set and adapts controls to multi-touch operation on the iPad interface. The iPad apps support file transfer methods including AirDrop and are available through Apple’s storefronts such as the Mac App Store. Separately, the ASAP suite is distributed for desktop as plug-ins for macOS, Windows, and Linux, and those plug-in versions include ARA support.
