ASAP is a set of audio plug-ins that allows transforming sound in a creative way. You are invited to play with the sound representation and the synthesis parameters in order to generate new sounds. The plug-ins can also be used in order to correct the defaults of the sound and to improve audio rendering. Thanks to the ARA2 integration, the spectral transformations are integrated into your editing workflow.

ASAP contains:

  • Pitches Brew [Premium]: The plugin, based on the ARA2 extension, allows you to draw and edit pitches and formants with great precision. This final version includes a marker system that makes editing curves faster and easier. In addition, it is possible to load frequency curves and markers in JSON, CSV, and CUE formats allowing exchanges not only with Partiels but also with many DAWs.. Check out the video tutorial!
  • Spectral Surface [Premium]: The plug-in allows you to draw shape filters on the sound spectrogram and to control their gain and the fades. The sound representation and the effect interface, made possible thanks to the ARA 2 plug-in extension, allow the creation of very complex and precise surface filters to reduce or increase specific parts of the spectral components of the sound. The plug-in can be used to compensate for annoying artifacts in the sound as well as to transform the sound creatively. Check out the video tutorial!
  • Spectral Remix [Free]: The plug-in allows you to control the balance of the harmonic, noise, and attack components of the sound. Beyond many original approaches, the plug-in can be used to highlight or hide certain audio elements and characteristics such as background noise, vocals, percussive sounds, and so on. Check out the video tutorial!

  • Spectral Crossing [Premium]: The plug-in allows you to cross the amplitudes and the frequencies of a source sound and of a side-chain sound to generate a hybrid sound. The plug-in can be used to creatively interpolate and transform one sound into another by gradually mixing the phase and amplitude components of the two audio signals. Check out the video tutorial!
  • Spectral Morphing [Premium]: The plug-in allows you to apply the spectral characteristics of a side-chain sound to a source sound in order to transform its timbre. By using a voice sound as the side-chain on an instrument sound as the source, spectral morphing can be used to make the instrument speak. Check out the video tutorial!
  • Spectral Clipping [Free]: The plug-in allows you to expand and compress the energy of spectral components within a range of thresholds. It can be used to silent low-level sounds such as background noise or to limit high-energy peaks such as high-pitched bird calls. Check out the video tutorial!
  • Formant Shaping [Premium]: The plug-in allows you to modify the vowels and play with the formant resonances of the sound. It can be used to change the spoken vowels of a voice or to vocalize instruments such as a drum set. Check out the video tutorial!


    The plug-in set supports multichannel processing at any common sample rate. The interface offers graphical themes to adapt to the graphical appearance of your digital audio workstations and your operating system.

The Spectral Remix and the Spectral Clipping plug-ins are part of the Ircam Forum free membership. The other ASAP plug-ins are part of the Ircam Forum Premium technologies bundle offering many tools, plug-ins, and applications to analyze, synthesize, and transform the sound. The Premium subscription allows you to download all technologies, and their updates and generate activation keys during the entire subscription period. Once installed on your machine, the technologies continue to work even if your subscription is terminated, with no time limit. The free membership allows you to use the demo version of the ASAP plug-ins.

ASAP is designed and developed by Pierre Guillot at Ircam IMR Department
SuperVP is designed by Axel Röbel (based on an initial version by Philippe Depalle) and developed by Axel Röbel & Frédéric Cornu - Ircam Analysis-Synthesis team of the STMS Lab hosted at IRCAM.
