Intercepting Audio Data going to Sound Card

Dear Team,

I want to intercept the audio data going to the default sound device, apply some changes to the data and then give it to the sound device.

I searched for the possible solutions and found the following two options:

  1. Develop a Filter Driver which sits above the sound card driver.
  2. Develop a Virtual Audio Driver.

Kindly suggest the best option. I started with second option using msvad. After installing msvad simple, I selected it as default output sound device from control panel. Now the data comes from the application to driver.

Here the point is if I route the modified data to sound device, since it is not default one, data will not be played. Is it possible to capture data, modifying and routing to sound device using msvad.

Regards.

Are you going to filter out that dreadful Vuvuzela noise for us?

I don’t want to filter out noise but add special effects to produce pleasant symphony :slight_smile:

Are you sure you want to do this in a (filter) driver and not in a
plug-in? i.e. VST?
Curious,
Hagen.

O great, so you intend to add the “noise” from “Forbidden Planet” to Bach’s
9th?
