I understand DISTORTION quite well! I hold an EE degree, managed an EE

Speech compression IS IS IS distortion. PERIOD!



I can see why your services were no longer required as Chief
Engineer... thanks for your comments.

I can see why you're more interested in $$ than in accuracy.

If I put a CONSTANT amplitude swept frequency signal, swept from 300 to
3000 Hz, audio bandwidth, to the input to a transmitting device and I get
a VARIABLE amplitude signal, swept from 300 to 3000 Hz, as the audio
output, the device has DISTORTED the audio.

That's just what speech compressors accomplish.

Every single speech processor is a controlled distortion device. You can
market and do salesmanship all you want. You are still selling a device
that distorts the audio.

Distortion is distortion!!

It not only Distorts the audio signal but causes either over deviation on FM
or Splatter on both AM and SSB, and that's the garbage you hear on adjacent
channels.
If you look real close on some built-in CB power meters, instead of the
signal increasing, it actually decreases!
Distortion = Flat topping of the signal...
