PDM
PDM Operator's Manual Version 2.4a • September 2019
Speed changes are virtually undetectable
We use the same time manipulation algorithms we developed for 25-Seven’s
groundbreaking Audio Time Manager.
PDM manipulates speed by intelligently splicing individual soundwaves, so pitch isn’t
affected and pauses aren’t unnaturally clipped. Critics have called our sound quality “superb”.
For details on how this works, check www.25-Seven.com.
Cough Mode
We’re into a segment, and a delay has already been built. Talent wants to give a message to
the producer.
n
Talent holds the
COUGH
button down. While it’s down, the delay memory stops
recording and talent is heard in the control room only. The audio already in memory
(from before
COUGH
was pressed) still goes to the transmitter.
This, of course, empties the delay memory by the number of seconds
COUGH
is held down.
When
COUGH
is released, PDM starts rebuilding its delay.
Another visual note…
In this manual, we squeeze or stretch the type font a lot to illustrate how PDM adjusts
audio speed. That’s because we wanted to make clear what’s happening.
In actual use, PDM’s functions are a lot more subtle. Most listeners won’t be able to tell
they’re in use. They’re also user-adjustable, so you can fine-tune the sound to your program-
ming and station’s style.
