SDIF-Edit is a tool for the visalization SDIF sound description data.

The SDIF format (Sound Description Interchange Format) aims at standardizing and optimizing the codification and storage of sound analyse and synthesis data in order to facilitate their transfer and interchange between applications. SDIF is used by various sound analysis/synthesis softwares, such as those from Ircam (AudioSculpt/SuperVP/pm2, Diphone/AddAn/ResAn), CLAM/SMS (from UPF Barcelona), Spear, and is also supported in the Max/MSP and PureData (FTM) environments, OpenMusic, OpenSoundWorld, etc. The format contains some standard specifications for the most commonly used sound descriptions (spectral and additive descriptions, FFT, filters, transfer functions, resonances, fundamental frequency estimate, voiced/non-voiced decision, temporal markers, etc.), and also allows the users to extend these types (i.e. to create new description fields) or to create new ones.

SDIF-Edit proposes a generic graphical representation of SDIF data, i.e. independant from the type of data contained in the SDIF file. It allows to browse the file structure (streams, matrices), and then to represent and edit graphically the data contained in these structures.


In OpenMusic, SDIF-Edit is used as an editor for the SDIFFILE object, which represents an SDIF file.
