audio-guided video synthesis for modern art

art/science collaboration with contemporary artist Jérôme Grivel, more details here.

user-guided multichannel source separation

demos produced within the ANR project SARAH, using multichannel Itakura-Saito NMF.

audio restoration

Louis Armstrong and His Hot Five denoised and upmixed (mono to stereo), using smooth Itakura-Saito NMF.
