Science Fair Project Ideas: Audio Speech and Music Spectrogram

Waterfall display of audio (speech and music) spectrogram generated by UltimaSound Spectrum Analyzer(Free)

This is a great project for science fair and teaching in middle and high school to better understand the elements of sound, voice and music: frequency, amplitude, pattern and spectrum

UltimaSound III is now released, please watch its demo here:

Are both programs UltimaSound Audio Spectrum Analyzer?

I'm curious what you used to write/ convert hello into sound.

No, UltimaSound only receives the word "Hello", using its spectrogram display. "Hello" is created using Coagula Light

What exactly is happening in this video?

[ultimaserial]

@Chintastic11

Sound has frequency and amplitude. Spectrogram shows the sound wave in frequency domain, using either color scale or height to show the amplitude. The PC on right generates sound with word "Hello" being its signature frequency. The PC on the left captures the sound and "decodes" the message.

Wiki may be the best place to have further reading
