/** * \mainpage BTrack - A Real-Time Beat Tracker * * A real-time beat tracker, implemented in C++. * * Written by Adam Stark, Matthew Davies and Mark Plumbley. * * License * ------- * * BTrack is made available under the GNU General Public License, version 3. Please see the included LICENSE.txt for more details. * * Usage - C++ * ----------- * * **STEP 1** * * Include the BTrack header file as follows: * * #include "BTrack.h" * * **STEP 2** * * Instantiate the algorithm by one of the following: * * * // to use the default 512 hop size and 1024 frame size * BTrack b; * * or: * * // to specify a hop size (e.g. 512) and have a frame size of 2 x the hop size * BTrack b(512); * * or: * * // to specify both the hop size and frame size * BTrack b(512,1024); * * **STEP 3.1 - Audio Input** * * In the processing loop, fill a double precision array with one frame of audio samples (as determined in step 2): * * double *frame; * * // ! * // do something here to fill the frame with audio samples * // ! * * and then call: * * b.processAudioFrame(frame); * * and to check for beats, simply call: * * if (b.beatDueInCurrentFrame()) * { * // do something on the beat * } * * **STEP 3.2 - Onset Detection Function Input** * * The algorithm can process onset detection function samples. Given a double precision onset detection function sample called 'newSamples', at each step, call: * * b.processOnsetDetectionFunctionSample(newSample); * * and then check for beats with: * * if (b.beatDueInCurrentFrame()) * { * // do something on the beat * } * * For any questions, please email Adam Stark (email at http://www.adamstark.co.uk). */
