I need some help here:

The rule of dB values is "always quote the reference"

I've been trying to work out what the compressor 0dB input level refers to. It doesn't seem to be FullScale, and obviously it's not referred to an analog value sinc that depends on conversion ratio.

Closest I can work out from the calculations and code produced is that 0dB refers to the numerical signal value of 1.0

So the +6dB limit should correspond to an absolute value of 2.0?

Can anyone confirm my deductions

Thanks

Mark

Hi Mark:

Please be aware the the maximum value that the built in dB converter has is 6dB. If you go past that limit you will start getting incorrect results (same goes for most compressors except for the extended range). The RMS compressor 0dB point is actually -3dB, this is because of the RMS value used in calculating the envelope feeding the compressor. Please run your experiments with this in mind and don't go above 6dB. Use a Readback Block to validate your results and a sine tone as a source. Don't use a DC value cell since you will loose what the influence of the RMS average. You can also use the level detectors to see where your signal is.

Let me know if this is clear.
