the quality of the recorded signal. Be sure to use a high-quality sound card for recording
your audio material, such as the
PHASE 24FW by TerraTec Producer .

If you save your audio files with a sampling frequency other than 44.1 kHz (for example,
96 kHz), you will have to convert them to a sampling frequency of 44.1 kHz if you want to
burn the results to CD. Here, too, be sure to use a high-quality software application for
converting the frequency.
•
You can attain optimum results using your ears together with the Difference function dur-
ing playback. This mutes all sound except for that filtered out by the Descratching and De-
noising 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 signal in the Difference signal,
the amount of filtering should be decreased.
•
If you record and edit your audio files using a sampling frequency of 48 kHz or even 96
kHz, you need to use a high-quality conversion tool to reduce the files to the CD-
compatible sampling rate of 44.1 kHz.
Important note:
Sound Rescue TerraTec Edition 2.1 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 re-
maining material, it becomes impossible to recover the original material. In cases as hopeless
as these, experienced professional sound editors apply highly complex audio editors to try to
copy similar sounding, already existing passages into the gaps. Likewise problematic is the
attempt to rescue material that is so full of noise that the original signal can no longer be dis-
tinguished. If, for all practical purposes, the information consists almost entirely of noise (an
extremely bad signal-to-noise ratio) and there is insufficient information available on the
characteristics of the original signal, or even worse, if nonlinear distortions occur too, the
quality of the
Denoising results will be limited.
