Effect: Remove DC-offset |
Description of
effect:
Centers the wave around the baseline.
Main benefit:
This effect will not alter the appearance of the sound. It will
however adjust any baseline shift added to the waveform during
recording or bad effect processing.
Description of parameters: The effect does not take parameters.
For you that
want to know more...
A baseline shift can occur if the recording
equipment does not filter out the DC voltage. If that is the
case, and you feel that it is of considerable strength, maybe you
should look into the analog electronics you use. If you have
never experienced any unwanted features, that is probably
not the case!!! The offset of a recording can
not be heard by the human ear, as the frequency of a stable
baseline happens to be the interpretation of exactly 0 (zero) Hz.
That also, is considered a frequency, and can therefor be
operated as such. It is for example possible to filter out a
baseline offset with any highpass filter. In Pristine Sounds it
is done by filtering out any frequencies below 5 Hz.
Please note that this effect is the least important function of Pristine Sound!
