• Designing a usable interface

• Synthesizing new sound events based on the rhythmic pattern and the timbre evolution of a recording model

Output synthesis depends on the selected sound material

Towards User-friendly Audio Creation

MotivationHow to easily extendone’s sound design palette?

• By collecting and sorting petabytes of sound samples??

• By experimenting with sound synthesis algorithms in too many different platforms, such as Matlab, PureData, Max/MSP, Minim (Processing), Csound, SuperCollider...??

Goals• Creating sound events

• Offering a usable tool for manipulation, navigation and sound composition

Research Ideas• Composing audio grains in time

according to the rhythmic pattern and the timbre evolution of a recording model

• Managing analysis of sound material and synthesis of new sound events within the MediaCycle framework [1]

Method Future WorkExtendingour synthesis techniquewith a physical approach

• Modal analysis of CAD models

• Modal synthesis with user-defined force and location

• Interface navigation based on semantic (physical properties) and signal-based features

Conclusion• A method for automatic extraction

and classification of meaningful audio grains.

• A technique for automatic synthesis ofcoherent soundtracks

• A usable interface for database manipulation and sound composition

• Automatic extraction of audio grainsbased on onset detection

• Sound material for synthesis= a recording model+ audio grains

• Synthesis process based on:similarity measurements+ onset detection
