TS2 (Transposition & Stretching) [online]

Introduction to TS2, specialized in time-stretching & transposition

TS2 is the development of the TS application, specialized in time-stretching and transposition based on the SuperVP™ audio engine. This new version provides  a number of new features and a completely redesigned—and more responsive—graphical interface. TS2 is a real audio editor that offers the possibility of combining several sounds in the same document and fades. Automation curves have been added to modify the main parameters of the application such as transposition, time-strecth, and  Remix options, and spectral clipping. A master module allows you to insert a string of plugins in VST2, VST3, and AudioUnit formats in order to finalize the sound with your favorite processing treatments.

Upon completion of this course, participants will be more comfortable when reading a sonogram, optimizing the analysis parameters for frequency representation and processing, setting up and correctly performing basic processing: transposition, time stretching, use of Remix functions, and spectral clipping.


Composers, musicians, engineers, sound engineers, sound designers, video editors, post-production professional, teachers...
