Hi all I'm looking for some software that will display up to four sine waves added together. My trouble is I don't really know what search terms to use!
What I am trying to demonstrate is the difference between equal temperament and just intonation - two ways of tuning in music. For example, the note A is generally 440Hz, 880Hz, ... A just tuned 3rd (Db) is 550Hz whereas the equal tempered 3rd is 554.37Hz (440 * 2^(4/12)). So adding the just intonation sinewaves should give a regular looking pattern whereas the equal tempered will be a bit "messy". If anyone knows of anything like this, I'd be keen to hear.
