Class that allows directly passing PCM float mono data to the sound card for playback. The sampling rate of the PCM data must be 44100Hz. @author mze

DFT stands for Discrete Fourier Transform and is the most widely used Fourier Transform. You will never want to use this class due to the fact that it

Interface for audio decoders that return successive amplitude frames. @author mzechner

FFT stands for Fast Fourier Transform. It is an efficient way to calculate the Complex Discrete Fourier Transform. There is not much to say about this

A Fourier Transform is an algorithm that transforms a signal in the time domain, such as a sample buffer, into a signal in the frequency domain, often

Simple example that generates a 1024 samples sine wave at 440Hz and plots the resulting spectrum. @author mzechner

Demonstrates the calculation of the spectral flux function hopping fractions of the original 1024 sample window. @author mzechner

Another mp3 decoder. I got a suspicion that the other one sucks a bit :/ @author mzechner

Simple example that shows how to decode an mp3 file. @author mzechner

A simple generator that outputs a sinewave at some frequency (here 440Hz = Note A) in mono to an {@link AudioDevice}. @author mzechner

Takes a plot and a decoder and plays back the audio form the decoder as well as setting the marker in the plot accordingly. @author mzechner

A simple class that allows to plot float[] arrays to a swing window. The first function to plot that is given to this class will set the minimum and m

A simple example that shows how to use the {@link Plot} class. Note that the plots will not be entirely synchronous to the music playback. This is jus

A simple example on how to do real-time plotting. First all samples from an mp3 file are read in and plotted, 1024 samples per pixel. Next we open a n

Calculates the spectral flux of a song and displays the resulting plot. @author mzechner

Some signal metric functions like energy, power etc. @author mzechner

Calculates the spectral flux of a song and displays the resulting plot. @author mzechner

Provides float[] arrays of successive spectrum frames retrieved via FFT from a Decoder. The frames might overlapp by n samples also called the hop siz

Calculates a threshold function based on the spectral flux. @author mzechner

A simple class that can read in the PCM data from a Wav file, converting the data to signed 32-bit floats in the range [-1,1], merging stereo channels

A simple example how to read in a Wave file via a {@link WaveDecoder} and output its contents to an {@link AudioDevice}. @author mzechner
