TDM 48-bit DP versions Explained
There are now two versions of each
of the URS TDM EQ's.
The standard 24-bit TDM version
and the DP 48-bit TDM version.
a TDM DP version?
DP stands for 48-bit Double Precision
It is only availble for the TDM
Do the DP
versions sound Different?
Yes, That is another reason for
the two different versions.
The DP versions have a fidelity
not found in the standard 24-bit TDM non DP versions
The DP versions do not clip internally
as easily as the 24-bit TDM non DP versions beacuse the dyanmic range of
the DP versions is double.
there two versions?
We felt it would be best to keep
the former TDM 24-bit non DP versions for those currently working on a
mixes started with TDM 24-bit non DP versions.
are the DP versions?
The TDM DP versions use twice the
DSP as the former TDM 24-bit non DP version. With the Accel card the DP
versions are still very efficient.
there no DP versions of the URS Compressors?
That is because the Compressors
already utilize 48-bit Double Precision Processing
DP versions twice as good as the standard 24-bit versions?
The best way to understand the difference
between 24-bit and 48-bit processing is to read
Digidesign's The Pro Tools 48-Bit
Mixer - A Digidesign white paper by Gannon Kashiwa here
You will notice that dynamic range
is twice as good but resolution is squared.
the RTAS DP versions?
The RTAS versions use 32-bit floating
/ 64-bit Double Precision Processing.
