double[] samples = getSamples(NUMBER_OF_SAMPLES); // implement this function to get samples from your source FFT fft = new FFT(samples, null, false, false); // optionally set last parameter to true if you want Hamming window double[] magnitudes = fft.getMagnitudeSpectrum(); double[] bins = leftFft.getBinLabels(sampleRate); // the sample …
java - Audio analysis: frequency vs pitch - Stack Overflow
https://stackoverflow.com/questions/8699360/audio-analysis-frequency-vs-pitch
I'm designing a simple tuner, so my target is displaying a note name (A, B, F#) and the distance in cents between the theoretic sound and the actual input.. I'm completely new to audio and signal processing, so I did some research and I found a thing called Fast Fourier Transform that will analyze the bytes and will give me the frequency. Also, I found a couple of …
Clojure/Java: Java libraries for spectrum analysis of sound?

fft - How to analyze audio input/spectrum correctly ...
https://dsp.stackexchange.com/questions/14183/how-to-analyze-audio-input-spectrum-correctly
I am quite new to Java and Signal Processing, but I was assigned a project dealing in audio processing. My topic given to me is a game that has a component of analyzing a song (any given song) and outputs data depending on the frequency currently being played (real time). ie: as the song plays, it outputs the current frequency (every second it outputs the current frequency).
