DESCRIPTION

thanks to Robin Davies

Have a look at the picture, it can analyse frequencies up to 176.2Khz which is quite high on the piano keyboard.

1.1, added audio table

also I would mention I would add the above but really it should be tailor-made depending on the purpose. Also it is possible to add a grid to calibrate frequencies by eye. With the audio table.:p

hey thanks, the freeze is all Robin Davies work from his original ensemble, and it would also be possible to freeze the audio table with a switch. it is a proof of concept, really, there is the possibility of adding a mouse area that outputs peak data when you click on the peaks, or even a peak-detect algorithm that goes over the audio table and compares the peak data, having variable refresh rates on the audio table input to save processing power. etc:)

This is great stuff. You don't mention or show the new freeze button and zoom knob you've added, both of which are valuable improvements.

Very cool. I like the xy display especially.
