Hi

I have a capture graph. Is there any way to control the volume of audio stream?
I want to increase and decrease the sound volume.

Thanks

  Probably there are a bunch of ways. IBasicAudio might be a good start.

  Thank you guys but none of the interfaces you mentioned are available to me. I use DeckLink audio capture filter and It doesn't support this interfaces.
  maybe you can introduce me filters that implement those interfaces.
  Thanks a lot

    I wouldn't expect the capture filter to support this. Volume is adjusted on the renderer.
