Is there an app that detects frequency?
The SpectrumView app can be used to measure the highest tones you can sing, obtain visual feedback of the frequencies in your speech, identify an annoying sound, calibrating musical instruments, or generally for all sorts of acoustic analysis.
Can audacity do FFT?
With either algorithm, Audacity will show a warning if the selected region is too short for the chosen size. There is an audio version of the Uncertainty Principle that says “Frequency_Resolution*Time_Resolution = 2.” Size lets you choose the FFT size which is the number of consecutive audio samples to be analyzed.
What is the best noise meter app?

Does Audacity have a spectrogram?
Selecting Spectrogram View To select Spectrogram view, click on the track name (or the black triangle) in the Track Control Panel which opens the Track Dropdown Menu, where the required view can be selected..
Which is the best audio spectrum analyzer for Windows?
Visual Analyzer is a free audio spectrum analyzer software for Windows. This software lets you analyze real-time phase spectrum of audio signals given through input audio devices.
How to calculate the spectrum from an audio file?
There is also a standard python module wave for loading wav-files, but numpy / scipy offers a simpler interface and more options for signal processing. 2. How to calculate the spectrum Brief answer: Use FFT. For more words of wisdom, see: Longer answer is quite long. Windowing is very important, otherwise you’ll have strange spectra.
How to extract spectrum from an audio file in Python?
Sorry if I submit a duplicate, but I wonder if there is any lib in python which makes you able to extract sound spectrum from audio files. I want to be able to take an audio file and write an algoritm which will return a set of data {TimeStampInFile; Frequency-Amplitude}.
Is there a way to extract frequency information from MP3?
However, notes below around middle C require too much precision for an FFT to work well. Since the MP3 already has frequency information in small time increments, is it a) precise enough to identify frequencies within about 2 – 5 Hz, and b) is there any code out that there does this conveniently?
