This article is in english, but the original one is in french. Just because many english-speaking people asked me about these transforms. (Cet article est en anglais, même si l’original est en français. C’est juste parceque on m’a plus souvent demandé en anglais qu’en français plus d’informations sur ce sujet. Mais ça devrait être plutôt clair pour les francophones.)
Through my migration to o-blog v2.5 I found some old experiments I did with FFT related to this Rapport d’écoute - Sur les épaules de Darwin (France Inter) - La forme des mots
Based on [[http://en.wikipedia.org/wiki/The_Blue_Danube][The Blue Danube - Johann Strauss]] transformed to image (FFT), some gimp filters applied, then transformed back to audio (IFFT).
- Blur 16x16
- Lens effect (one of the best sounding ones)
- Pixelize 8x8
- Wave effect
- Wind effect, in my opinion, the best one, sounds like a kind of music box with reverberation
Oh and no, I didn’t find the original audio file… But I have the image (100 pps 48 bpo):
