ence on the quality of the recorded signal. Be sure to use a high-quality sound card for re-
cording your audio material, such as the
TerraTec AudioSystem
EWX 24/96

If you save your audio files with a sampling frequency other than 44.1kHz (for example, 48
kHz), you will have to convert them to a sampling frequency of 44.1kHz. Here, too, be sure
to use a high-quality software application for converting the frequency.
·
Best results are achieved by evaluating the sound with your own ears using the
Difference
function during playback. This function plays only the sounds that have been filtered out
by the
Descratching
and
Denoising algorithms
. In the best circumstances, you should only
be able to hear noise with this function. If you can detect the presence of the original sig-
nal in the
Difference
signal, the amount of filtering should be decreased.
Important note:
Sound Rescue
TerraTec Edition 2.0
is a fast and effective tool. You will be amazed by how
much you can improve the sound quality of old records and distorted audio files. However,
please do not expect any miracles when trying to restore material that contains gaps or
jumps. Once the signal has been lost to the point where there is insufficient redundancy in
the remaining material, it becomes impossible to recover the original material. In cases as
hopeless as these, experienced professional sound editors apply highly complex audio edi-
tors to try to copy similar sounding, already existing passages into the gaps. Likewise prob-
lematic is the attempt to rescue material that is so full of noise that the original signal can no
longer be distinguished. If, for all practical purposes, the information consists almost entirely
of noise (an extremely bad signal-to-noise ratio) and there is insufficient information avail-
able on the characteristics of the original signal, or even worse, if nonlinear distortions occur
too, the quality of the
Denoising
results will be limited.
