- UltimaSound: A free PC-based audio speech and music spectrogram (frequency spectrum analyzer) software. UltimaSound is a real-time audio signal analysis software, and it is FREE.! With UltimaSound spectrogram software and a laptop, you can see a vivid picture of your voice and music in frequency domain in real time!
- Physics Music Pitch Sound Spectrum. Upload your own. The spectrum analyzer above gives us a graph of all the frequencies that are present in a sound recording at a given time. 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.
- Modified sox to try doing logarithmic frequency scaling on the spectrogram output.
An introduction to how spectrograms help us 'see' the pitch, volume and timbre of a sound. The spectrogram used in this video is called Signal Spy for iPad.
SPECTROGRAM is…
A musical chord is a sound, but it is also a combination of other sounds (the musical notes that compose the chord). Actually, any sound is a combination of other elementary sounds, which are called pure tones. They are just like musical notes, each which its frequency. The spectrogram allows you to see all the frequencies that combine to produce a sound. To try it out, make sure you allow the website to use the microphone. Then speak into the microphone and see what frequencies are present in your voice. You can also use this spectrogram to tune musical instruments or to create music; for example, you can explore different musical scales, and add effects often used by musicians and engineers. This videoshows how you can make amazing music with it.

The spectrogram is one of the most commonly used tools in physical sciences and engineering; it is part of the technology behind voice recognition and phone communications.
