Ircam AudioSculpt v3.2.7 MacOSX - HEXWARS

Display: Zoom from an overall view down to sample level, synchronized sonogram (time/frequency), spectral envelope, processing sequencer.
Analysis: FFT, LPC, True Envelope, fundamental frequency, partial following, different methods of automatic segmentation, formants, and tools for listening to selected sections of the spectra with harmonic display.
Markers and Segmentation : transient, beat, standard markers detection, import & export supported.
Sound Processing: A processing sequencer with individual tracks makes it possible to listen to them in real-time prior to creating the final result:
Filtering: directly on the sonogram using a pencil or eraser or by specifying with the mouse the points forming a polygon. Manual source separation and denoising are possible.
Compression/expansion: allows modification of the length of a sound without changing its pitch or timbre while maintaining the quality of the transitions.
Transposition: using a specific editor the user can transpose a sound without changing its length and without loosing sound quality ; separate transpositions for sound and spectral envelope for timbral modifications.
Denoising: spectral subtraction with interpolation of sound estimations.
Cross Synthesis: application of spectral data from one sound to another in order to create a hybrid sound or a transition from one sound to another.
Partial Synthesis: creation of a new sound from partials found via an analysis.
