Editor: The program "AudioAnalyser" is a realtime Frequency analyser for audio signals.
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 application is written in C++ and uses the VCL library and Win Api calls.
