The Fourier Transform is a powerful tool allowing us to move back and forth between the spatial and frequency domains.

The Fourier Transform is a powerful tool allowing us to move back and forth between the spatial and frequency domains. This applet helps students feel comfortable, helping to build a strong intuitive grasp of how signals in one domain correspond to signals in the other.

Students can load scanlines from common image patterns and see that scanline's Fourier...

Whistle a melody and watch this program graph the pitch in real time.

Whistle a melody and watch this program graph the pitch in real time. The Frequency Analyzer technically speaking performs a Fast Fourier Transform of the sound (you need a sound card and a microphone to use this program). What it means is that it analyzes your voice and splits it into its component frequencies. Watch patterns of speech, the harmonics of vowels and the...

I decided to explore both the musical and programming aspects of C# all at once. As a first project I built the Note Detector. It opens the sound card and if you have a mic it will tell you the musical note that it hears. It displays the note name C,D,E#,etc and it shows you the note's position on the staff. Note Detector can be used as a guitar tuner or a singing voice pitch trainer. I use it...
