One frequency or five thousand frequencies, if they are all at the
same amplitude the resultant modulated signal is still unintelligable.
You simple can't transmit intelligence with a constant 100% modulated
AM carrier.
Now if you compressor was advertised at giving a average of 50%
modulation, then I would not have as much issues. On average an AM
signal will be about 33% average modulation with peaks at about 100%.
The human voice generally lies between 3 to 1 and 5 to 1 peak to
average power.
