I have a dubt in the signal conversion on the sigmadsp processor:
I'm trying to realize a VU meter with a scale -20 to +3dB with a time constant of 300ms.
As suggested I'm using a "Signal Envelope" with TC = 66 and Decay = 66
The input is a microphone, I send a sound that generate a saturation ... and I stop the sound... the "Signal envelope" take some seconds to
give a correct response.
I saw that with a hard clipper with the limits +/-1 the problem don't appear.
What is the A/D value for a DSP digital value 1.0 ?
What is the DSP value for a A/D full scale input?
I attached the sigmastudio test project
