Ekstasis

Ekstasis is currently a rapidly produced prototype version of a Digital Signal Processing (DSP) framework which seeks to provide signal/data processing modules which can be strung together via Boost library interprocess message queues. Tools for creating and destroying the communication queues, loading/saving PCM 44100 Hz to/from the signal processing chain, windowing the data (currently only a Hann windowing function module), performing a Discrete Fourier Transform (DFT) on the data (using FFT, currently only real part), detecting the presence of an event within a data segment/packet via normalized spectral signature matching/comparison, and the generation of a midi file from the detection of said patterns (i.e., event occurrences) as output are currently available.
