Compressor RMS envelope follower
Posted: Mon Feb 12, 2018 11:29 am
Hi,
Working on an RMS compressor.
To test if the envelope follower is correct, I injected a 1 KHz sine wave tone at (-12 dBFS).
The envelope follower reads (-15 dBFS) which (I guess) is expected due to 'crest fector' of sine waves which is (-3 db).
That means that the 'distance' between a peak and RMS of a sine wave is (-3 dB).
So, is all of this correct? Should I expect an RMS compressor to 'read' a sine wave signal at 3 db lower than its rating?
Had I used professional measuring gear (generator and analyzer) - and dialed in a sine wave signal, will the 'knee' of the RMS compressor run at (-3 db) lower than intended?
