Overview:

Spectro is a real-time audio spectrogram generator for the web. It allows users to visualize sound from their microphone or audio files on their device. The generated spectrogram represents the frequencies present in sound over time, with time represented along the horizontal axis and frequency along the vertical axis. Users can customize the appearance of the spectrogram using various options such as sensitivity, contrast, zoom, frequency range, frequency scale, and color scheme. Spectro works on the latest versions of Chrome, Firefox, Safari, and other Chromium-based browsers.
