Sine wave generator ?

Hi,

One of my hi fi speakers is distorting at certain frequencies and looking at the web it is suggested that a tone generator may be useful in identifying where the distortion is originating. My first thought was to write a tone generator using Livecode but having searched the dictionary I can not find any method of generating a given tone on the fly. Livecode appears to have the commands as part of the Beep commands but they do not work on desktop. Have I missed something obvious ?

This is what I would like to create : https://onlinetonegenerator.com/. It seems a pity that that it is possible in html but not in Livecode. Any thoughts?

best wishes

Simon

The beep command is far to granular to generate a tone. You have to import a sound file and play it.

Or would a MIDI library be able to generate it? (thinking of the example with sine/square/triangular etc -- should all be doable with MIDI?)

It's outside of my comfort zone, but i know Paul McClernan has created a MIDI library and shared on github - https://github.com/PaulMcClernan/OpenXT ... e-CoreMIDI

As the link suggests however, this is pretty much MacOS only - but hopefully that helps?
