Problem with audio, very loud sound #21

Open delcommerce opened 5 years ago

delcommerce commented 5 years ago

I'm a beginner with CasparCG, I'm using the RedCast client and sending the signal via SDI.

But the sound is really bad, I do not know how to control the volume in the CasparCG. In RedCast the volume control in the setup menu does not work correctly.

So my question is whether there is any configuration to be made in the CasparCG "config" file to have the volume contolle. I really need help.

There could be a lot of potential reasons for this, so I can't help you pinpoint based on just your description unfortunately. Let me go over a few potential issues.

  1. Possibly your decklink is defect. Try to add a system audio consumer to see if this is the case. You can do this by typing ADD 1 AUDIO in the CasparCG terminal window.
  2. You might be dropping frames, which can cause the audio to sound distorted. You can find out whether this is the problem by typing DIAG in the CasparCG terminal window and look for dotted red lines in the window that appeared.
  3. There might be a difference between the format your channel is running in and your mediafiles. If CasparCG Server cannot handle the specific mediafile you might get undefined behaviour. It would be great to know at least your server version and possibly also some details about the source file. (Resolution, frame rate, sampling rate)

I don't think what @baltedewit said is very relevant for you.

There is a way to control the volume of layers, the documentation for the commands is at https://github.com/CasparCG/help/wiki/AMCP-Protocol#mixer-volume
