Sonic Visualiser

h1. Sonic Visualiser: architectural summary

Sonic Visualiser is a substantial application written in C++ using the "Qt":http://qt.nokia.com user interface toolkit.

It is a cross-platform application that can be built on (at least) OS/X, Windows, Linux, and Solaris, but it has a substantial number of dependencies on third-party libraries which contribute to the complexity of the build process. The code also does not currently build with Visual C++; the Windows build is done using MinGW and g++.

The Sonic Visualiser code is provided as a number of separate libraries, with varying dependencies. These are managed in separate projects on this code site, and are as follows:

* "*svcore*":/projects/svcore -- Non-interactive code, without user interface or audio device I/O.  This contains a number of submodules:

** *system* -- Some system-dependent code that Qt did not provide

** *base* -- Miscellaneous handy classes 

** *data/fft* -- FFT code

** *data/fileio* -- Audio file import and export and related classes

** *data/midi* -- MIDI-related code

** *data/model* -- Data models used for Sonic Visualiser's internal representations. These include waveforms (including zoomed previews) as well as grids (spectrograms etc) and editable data (time/value plots, MIDI-style note tracks, text etc).

** *data/osc* -- OSC control
