Java .wav file frequency analysis - incorrect frequency. Ask Question Asked 5 years, 11 months ago. ... The file I'm feeding is a simple one-frequency sound, at 440Hz, with a duration of 1 second. After seeing the graph, though, there's a problem: I have a single frequency peak, which is exactly what I'm expecting, but the peak is situated at ...
Clojure/Java: Java libraries for spectrum analysis of sound?
https://stackoverflow.com/questions/3444226/clojure-java-java-libraries-for-spectrum-analysis-of-sound
This Archived Blog shows a java implementation of the FFT algorithm which is very concise and reads audio files and calculates the frequency spectrum. You could also check Jtranforms open source FFT library. Unfortunately the blog is gone, here are some other resources on FFT.
How to Determine Frequency (In Hertz, Real Time) with Java ...
https://softwareengineering.stackexchange.com/questions/136215/how-to-determine-frequency-in-hertz-real-time-with-java-sound
You will need to do some spectrum analysis. Take a short piece of audio data, maybe some 256 samples, then calculate a fast fourier transform (FFT) for each piece of data. However, a fourier transform itself is not enough since the process of cutting up sound in short samples introduces some distortion.
