I have found no sonogram on the web, so I made one. It uses GEM and uses a lot of CPU load, but it can be very useful in some cases, for teaching purposes, for example. I hope you'll enjoy and I will be happy to receive your feedback.

Cheers

@Pierre-Guillot neat!

@Pierre-Guillot Brilliant! (and very pretty)
It didn't work for me (Windows Pd-extended)
Your object gets confused with [sonogram~] from the "unauthorised" directory.......
I have taken the liberty of renaming it (for us heretics that don't use macs or Vanilla!!

Didn't work on my machine either, even though I'm on vanilla, since I haven unauthorized. I also renamed it, but I'm keeping it to my self, nothing to worry about. It's really great! Thanks for sharing..

Thanks you ! I've added "pad" before the name to avoid the confusion with the "unauthorised" library ("pad" doesn't mean anything but I am weary of finding names). I'm cleaning my other abstractions before sharing but you can already find a spectroscope, an oscilloscope and a VU meter on my github repository. Perhaps this may also interest @mx. Feel free to change or rename the patches, I have absolutely no problem with that !
