The program uses the user's microphone to visualise the sound signal of the microphone live. It also applies a Fast Fourier Transformation (FFT), this shows the user which sound frequencies are present in the sound. Frequency in Hz is replaced by note names of musical instruments: A - G. This enables the user to easily see what notes are being played in music.
- How high can I sing?
- How low can I sing?
- Can I sing what I hear?
- Which notes are being played (and when) in the music that I hear?
- What is the difference in sound spectrum when comparing, guitar, flute, piano and cello for example?
Real Time Spectro program written by Norm Spier: nasmusicsoft. RealTimeSpectro also accesses the microphone and implements a row and spiral visualisation for the sound frequency plots. However, his program calculates the frequency power with a spring system simulation, not an FFT.
Another program by Norm Spier, SpectraTunePlus. is able to load sound files and shows a frequency spectrum history. SpectraTunePlus has a more intimidating user interface. Norm Spier has written a lot of helpful theoretical, practical and nice-to-know information on his website.
Sonic visualiser is another program which is a bit similar to my project's program. This program can only handle complete audio files.
