Hi,

I've developed some web applications using the web audio API: http://www.v-choqueuse.com/webapps/

Voice Removal
Vuvuzela Sound Denoising
ITD-based Audio Spatializer
Binaural Spatializer
Convolution Reverb

Don't hesitate to give me some feedback

Why would someone want to denoise Vuvuzela sound ? What we all really want is more Vuvuzela !

OK, be ready for a vuvuzela web simulator with 3D sound rendering and convolution reverb

That's quite impressive

The saw waves and square wave seem to be antialiased.
Did you generate them yourself or do you use the APIs generators ?

You can see what is going on if you have a look for the source code of the page. Apparently, Choc is using a function of the Web Audio API to create the oscillators and specify their type, so I imagine they are already anti-aliased

As specified in the API, the built-in oscillators must be antialiased (see http://www.v-choqueuse.com/webapps/elec ... _generator for example). This API contains many interesting features. For example, if you use a waveshaper, it will automatically upsample/downsample the data to avoid aliasing effect (see http://www.v-choqueuse.com/webapps/guitar_amp for a waveshaper distortion).
