[...] PitchShifter — изменение тональности звука, черз pitch-shifting (я думаю, что этот термин лучше оставить без перевода), т.е. без изменения длины звука. [...]

Can you post the SWFs so that others can run the same tests?

You can check thé dspdimension source link to get their pure C code. Should be easy enough to use no?

Any one know of a good objective C example of this source code?

Bonjour,

J’ai découvert droolbox ici (http://europarlement.touteleurope.eu/fileadmin/modules_animes/frise_multimedia/#/fr/accueil).

Auteur de ceci (http://www.classissima.com/fr/people/chronologie_compositeurs_musique_classique/), dans le même esprit, avec beaucoup de sueur mais bien moins “joli”, j’ai beaucoup aimé les potentiel de votre frise. Bravo.

Si la droolbox est un jour “disponible publiquement”, je veux bien en être informé.

Cordialement,

Laurent

Hello there, great job on the code.

I’ve been trying to adapt something of sorts for microphone input in realtime for the last few days with no such luck. Though I can get it to pitch and keep the duration, the sound comes out choppy and really unusable. I think I might be handling the mic sampling unproperly, or iterating over the sample data without the correct “overlap factor”, as you call it in your example.

Do you know of anyway I can achieve this? A realtime microphone pitch without change in duration and quality results? Any help at all would be much apreciated.

Guys, don’t forget that bottle neck in most GUI’s are not script execution, but translating the vectors and DOM’s into pixels on the screen. Flash has done a lot of homework in the later end, so even though it lacks on the code execution, the drawings speed well compensates the rest.

After all, a good GUI should have a good balance of processing on the client side and server side.

@constantine: I actually did test Opera 11.0 and 11.1. Check browsers_v8_log.csv linked above. I think the JS engine is not correlated to the major version number for Opera. The last speed boost was at a minor release (10.6). I don’t think the virtual machines can’t really improve at each version of a browser with a 3 month release cycle. You need to push major changes to see bigs leaps in performance. So the engine making big progresses from time to time makes perfect sense.

@zedia.net: I agree that the main bottleneck currently is the rendering engine, especially in 3D. But we know Molehill allows 60fps with nearly everything you can push to it. So the next bottleneck is the AVM2. Currently there’s also lots of specialized code (3D engines, AR engines, sound/image processing…etc) that is not visual and need to use tricks (like memory instructions with Apparat) to have correct performance. What bogs me right now is that it would make perfect sense to use Javascript as we use Alchemy (as a speed booster) and that’s a shame.
