My GSoC2007 application: “Real-time spectral transformations”

Next Monday finally starts the google summer of code, here my finally accepted application:

Title: Real-time spectral transformations
Mentor: Pau Arumí Albó
License: GNU General Public License (GPL)
Abstract: Revamp all CLAM SMS transformations. Turn real-time all those still aren’t and have them working on Network Editor. For example: Harmonizer, Morph and Time Stretch. Make nice prototypes for use them with Prototyper and have special focus on some. Also make real-time Voice2Midi and all those widgets which can be needed.

Some words more about this:

• Port it to real-time and NetworkEditor these spectral transformations: Harmonizer, morph, time-stretch and pitch-discretization.
• Fix gender change (already real-time, residual improvement)
• Make a harmonizer prototype with sliders to control each “voice” gain and the option of control them by midi too.
• Realtime Voice2MIDI. Piano-roll widget for NetworkEditor/Prototyper.
• More general improvements on SMS transformations over issues that can arise during the development of the project.

Last days I was mainly reading about SMS transformations and its model and the “Spectral Processing” chapter of the DAFX (Digital Audio Effects) book.

More news and details about this project here soon.
