Basically, you can draw sound!

SpectroDraw’s interactive spectrogram lets you paint frequency content directly, adding a new dimension to sound design. Create sound effects, convert to midi, and more.

In SpectroDraw, the spectrogram uses both hue and brightness to represent sound. This is because of a key issue: To convert a sound to an image and back losslessly, you need to represent each frequency with a phase and magnitude. The "phase," or the signal's midline, controls the hue, while the "magnitude," or the wave's amplitude, controls the brightness.



You can use SpectroDraw to create glitch sounds, drums, alternate reality sound effects, and other sounds that cannot be made with traditional synths. You can also use the eraser or noise remover tool to restore samples.

 

SpectroDraw Pro cost $39.99.

 

@webhead Do you offer any discounts?

 

Nope. I'm just the messenger.

Izotope Iris anyone?

 

Its very cool. The free version can get you pretty far, and you can download audio, image, and midi. Quite a few effects and brushes, overall great considering its free. However, the pro version has even cooler features, including locking your brushes to a key, which can give you really wild color bass sounds.

Overall really great if you are into wasting your time making incredible, terrible sounds, like I am lol. Thanks for sharing!

 

I have totally forgot about that. I've even made a horror sound pack with Iris 1. Now I'll check about version 2
