How to denormalize values to do the Harmonic Product Spectrum
I'm trying to execute the HPS algorithm and the results are not right. (48000Hz, 16bits)
I've applied to a buffer with the recorded frequency several splits, then a Hanning window, and finally the FFT.
I've obtained a peak in each FFT, that…

How can I estimate the pitch of audio that I am currently recording in python?
I believe a lot of the libraries I have looked into require loading an audio file. Is this possible to do with audio that is being recorded live? If so, what library should I use?

Convert Audiorecord Data to process FFT
I have been implementing a Polyphonic signal pitch detector so I started to code my Program doing (RecordData, Convert Data, Zero-padding, Windowing, FFT, Peak detection). At first I tested it with sounds I already new which values I should get, and…

How to Calculate fundamental frequency of microphone input using Harmonics data
I am able to calculate the fundamental frequency of a real-time audio input from the microphone in Unity by finding the highest peak bin using GetSpectrumData function.
But it fails for lower frequencies.
I think that I get the frequency of…

Fast frequency measurement
I need to measure signal frequency while the musicians play music, and it happens to be a bit too fast for FFT (Fast Fourier Transform).
Musicians play music at 90-140 bpm. This means that there are 90-140 groups of notes each minute, up to 8 (more…

Pitch detection - count notes
I'm using an autocorrelation algorithm to perform pitch detection on monophonic sounds (humming, whistling) and I get results good enough for what I'm attempting to do.
But If I whistle a melody with the notes G F# D# and log the result I get this…

Matlab - better understanding the FFT and finding Pitch
I know there are tons of topics on finding pitch from the FFT, and I've gained a decent understanding of the whole process from turning data samples from time-domain -> frequency-domain, but there are still some areas (probably more advanced) that…

How can I process a sound signal using matlab, get the frequencies and use it on java?
I'm new to signal processing and i'm developing an application that involves extracting pitch of a sound playing wav file, tried a few approaches to directly extract pitch using java (using FFT and DFT) however, it was not possible to go on with it…
