The resulting graph is known as a spectrogram. The darker areas are those where the frequencies have very low intensities, and the orange and yellow areas represent frequencies that have high intensities …

A spectrogram is a visual frequency map of audio — time on the X axis, frequency on the Y axis, brightness = amplitude. Built using the Fast Fourier Transform (FFT), spectrograms are used in …

A spectrogram is a visual representation of the spectrum of frequencies of a signal as it varies with time. When applied to an audio signal, spectrograms are sometimes called sonographs, voiceprints, or …

SpectroDraw is a free, browser-based spectrogram editor that lets you draw, visualize, and sculpt sound directly on the frequency spectrum. Perfect for sound design, audio repair, and experimentation.

Visualizes audio as a spectrogram to spot hidden patterns, tones, and messages embedded in sound. Spectrograms show how intensity changes across frequencies over time. They are a common way to …

Visualize the frequency spectrum of any audio file over time. Free browser-based spectrogram viewer with adjustable FFT, color palettes, and PNG export. Like Spek, but online.

A spectrogram shows how frequencies change over time. The vertical axis represents frequency (Hz/kHz), the horizontal axis represents time, and color intensity reflects amplitude.
