specific demos wanted, question about media streams processing api

Hello list,

Could someone of you give me links to demos with :

- full fft implementation in javascript (is this one up to date ? 
https://wiki.mozilla.org/Audio_Data_API)
- full convolution engine implementation in javascript too.
using both of the 2 apis ( Web audio api and media streams processing api)
- a sort of offline processing with media streams processing api, to 
represent waveform (I know with the comparison of the 2 api in the wiki, 
that "offline" processing in media streams could be more difficult to 
achieve, that's why I'm looking for this kind of demo)

Also, is there, inside or outside TPAC lyon, a meeting with other audio 
working group participant scheduled ? (I'll be in Lyon for devtracks on 
Wednesday, Thursday and Friday, and it would be fine to meet someone of you)

Regards,
