Looks good, thank you for your contribution.

 

I hope at some point your work can get rolled into a future release of OWR.

Yes, OWR uses dBFS, it has to be this way because it can use different receiver hardware, each with different gain settings.

 

It could be possible to calibrate using a signal generator, but most admins don't have access to such things.

 

The Kiwi uses standard hardware, so the software can be roughly calibrated using pre-determined average values, however these do vary from batch to batch, and there is an offste value that can be applied by the admin, if they have a suitable calibration source available.

The peak hold outline will provide an indication of the maximum deviation over a period of time.

 

I worked on broadcast transmitters in the UK, during a period of time we called "the loudness wars", it was when stations started to use more processing on their FM transmissions, and the deviation kept on creeping up, as they tried to sound louder than the other stations on the dial. Some were really excessive, and you couldn't listen to them for more than a few minutes before they became fatiguing.

 

Fortunately some sense prevailed and things improved, but there are still a reasonable number of FM pirate stations around London, that use so much deviation and processing that they make your ears bleed.
