Diphone Studio is used for sonic morphing. After an analysis phase, which breaks up the sound into chunks (called diphones), the chunks are placed in a dictionary. The user then defines which diphones are to be used and in what order in time. Using this information the program "morphs" from one diphone to the next to obtain the final result.

Main Applications

• Composition
• Sound Design
• Post-production
• Multimedia

Main Features

Segmentation/Analysis. In order to facilitate the analysis phase, Diphone offers automatic segmentation of your original sound file. In addition, the program offers a dedicated graphical interface that lets the user chose the analysis plug-in and to adjust the parameters of the analysis.

Dictionary Editor. Browsing through the different dictionaries, selecting segments, creating new dictionaries, and saving them.

Sequence Editor. Construction of diphone sequences in time and modification of the characteristics of connection objects, such as the duration of a connection, a linear connection, etc.

BPF (break point function) Editor. Creation and modification of sampled values such as the evolution of the fundamental frequency in a segment or the range of partials of a sound.

Additional Information

At a more general level Diphone Studio can be used as an editor for the control of different synthesis methods implemented as plug-ins: Additive Synthesis with its analysis package (AddAn). Chant (Source-Filter Synthesis) with a Resonance Model analysis (ResAn). Spectral Envelope for voice analysis. An innovative feature is the use, in additive synthesis, of Hidden Markov Models for the analysis of inharmonic sounds.
