Hi All,

Is the level meter available an RMS meter? Are other meters available? (peak or average)

Any idea if it is possible to use a signal detector to detect the presence of audio signal (input, output Spdif in/out) so i can indicate the presence of audio in my PC application (indication like an led: RED = no audio / GREEN = audio present), e.g. by reading the data of this block, or using the GPO's.

Thanks a lot.

Hi Ramon,

Yes there are different types of level detector incorporated into sigmastudio. Here is a useful explanation of what's possible. There is an example project that shows how to set a GPIO pin based on whether the audio is above a particular input level.
