The program Multisine is an audio signal generator.
All signals are calculated offline. After the calculation it is possible to store the data in a .wav file or playback data with your soundcard.
The application is written in C++ and uses the VCL library and Win Api calls.

You can combine the "AudioAnalyser" with my other application "Multisine", if your soundcard supports the full duplex mode (only very old soundcards don't).
With this combination you have a full equipped audio suite for your measurements.

The program HarmonicTune is an general purpose chromatic Instrument Tuner.
You should be able to tune nearly every kind of instrument with it (including brass, strings, piano, guitars...).

Nevertheless the algorithm for the base frequency detection is not perfect, but I hope to improve it step by step over time.
The application is written in C++, uses the libraries "wxWidgets", "boost" and "portaudio" and is compiled and organized with the great free IDE "Code::Blocks" using MinGW.
