IRCAM releases IRCAM Lab TS – Next Generation Time Stretching Application


The Institute for Research and Coordination in Acoustics and Music (IRCAM) has announced the release of IRCAM Lab “TS” (Transpose/Stretching), a powerful stand alone application that revolutionises the way audio signal can be processed.


Unlike other time stretching applications, “TS” uses an advanced phase vocoder engine (SuperVP) as for the analysis/synthesis functionalities of “AudioSculpt”. Phase vocoder technology provides high-quality sound processing in real-time and offers amazing results even when used to transpose or stretch audio waveforms radically. It is able to transpose and/or pitch a WAV or AIFF audio file with extremely accurate results and minimal artefacts making it possible to process professional recordings with transparent results. A life saver for audio engineers and broadcast technicians!

But “TS” is much more than a simple time shifting tool. the application can transform an audio signal at extreme settings making it a totally new sound ! Simply drag a WAV or AIFF file into “TS” and stretch it down by 100%. That will give you a quick idea of how powerful it is. Now use the formant, transient, sinus or noise sliders to sculpt your sound and create totally original audio textures. Sound designers, DJ’s and musicians will be amazed by the unlimited possibilities offered by “TS” to create totally new sounds. From a basic drum loop to pianos, voices or any other audio signal, “TS” can make something totally wild and original out of it…

IRCAM Lab “TS” also includes real time Midi remote control and a live editing export feature. That enables users to export totally original sounds created in “TS” as easily as clicking the mouse. A DJ’s dream come true!

    any idea what is the limitation of the demo!?! I play now with it and seems to have no limitations …

    • Haven’t a clue. A previous demo was time limited (expired at a set date), so perhaps this one is the same.

    Hello Felix,

    The demo is for 15 days and it is full feature, no limitations.

    So 15 days after you start it, it will expire.

    The good news is if you like it is at a special introductory price of $99 instead of the $249 list.

    The official launch will be taking place next week.

    Best Regards,
