HEDD allows you to add tube-like
characteristics to your digital audio with two knobs, specifically
pentode and triode. A separate knob for each tube type is available
at the flip of a switch!
TRIODE
The triode function creates
a triode like harmonic structure. This affects the bottom of your
signal by fattening it up. This function contains strong even order
harmonics. It should be noted that even order harmonics may or may
not be easy to hear depending on the program and how much you are
adding. This function is not strictly even order harmonics. The
harmonic structure changes with signal level and the amount of process
being applied, just like it does in a tube and the analog world.
PENTODE
The pentode function creates
mostly third harmonic information but contains some even order harmonics
and some higher order odd harmonics depending on the signal level
and the amount of process. This is like driving a pentode into over
load in a controlled manner. The pentode process makes things sound
brighter, brings out detail, and also affects the triode process
because the two processes are in series. There is also a compression
effect that takes place if you run the process at higher settings.
TAPE
The tape function emulates magnetic recording tape. Recording tape
distortions are odd harmonic, starting with the third and fifth.
As you increase the level on tape the harmonic content increases
and higher odd harmonics are added. With a tape recorder there are
record and reproduce EQ circuits that modify the harmonic content.
The result is a sound that fattens up the bottom and midrange of
a recording and as you increase the process there is a loss of hi
frequencies with respect to low frequencies. This is a result of
the compression function and eq. curves in the process. The compression
also squashes peaks and results in a higher average level.
