We have developed an online spectrograph program with a bank of over 30 audio clips to visualize a variety of sounds.

Convert an audio file into a spectrogram image online. Pick between multiple color palettes and choose what output size you want. (MP3, WAV, FLAC and OGG)

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

Image to Audio, Spectrogram Player. This app allows you to convert an image to audio file, and Decode, Play a audio file via spectrogram.

Chrome Music Lab is a website that makes learning music more accessible through fun, hands-on experiments.

Our Audio Frequency Viewer can show you a visual illustration of your audio files and help you identify the frequencies they contain - a "visual sound image".
