This audio spectrum analyzer enables you to see the frequencies present in audio recordings.

The Interactive will graphically display information about the frequencies (and their amplitudes) over the course of time. The tool also is capable of displaying a Fast Fourier Transform (FFT) …

The plot spectrum takes the audio in blocks of 'size' samples, does the FFT, and averages all the blocks together. For those familiar with the free open-source program, Audacity, this webpage …

Tool to perform spectral analysis of audio files (WAV, MP3, etc.) and display any hidden data in sound frequencies and their visualization.

In many media, such as air, the speed of sound is approximately independent of frequency, so the wavelength of the sound waves (distance between repetitions) is approximately inversely …

This spectrum analyzer creates a graph of all the frequencies that are present in a sound at a given time.

Maztr's free online Audio Spectrograph is a quick and easy tool you can use right in your browser, without downloading any software, to view live frequency and amplitude data from your audio …

See the Spectrum: The canvas will show a bar graph representing different sound frequencies. Lower frequencies (bass) are on the left, and higher frequencies (treble) are on the right.

Frequency-domain graphs – also called spectrum plots and Fast Fourier transform graphs (FFT graphs for short)- show which frequencies are present in a vibration during a certain period of …

A sound spectrum is a representation of a sound – usually a short sample of a sound – in terms of the amount of vibration at each individual frequency. It is usually presented as a graph of …
