LEVEL NORMALISATION

Pressing
Here you may set new levels for the selected sample and also normalise it.
Normalising is a technique where the sampler will analyse the loudest part of a signal and
then adjust the whole sound to be at its optimum level - i.e. the loudest part of the signal
is at the unit's maximum level before distortion and the rest of the sound is brought up in
level proportionately. This increases signal to noise ratio and dynamic range. It also allows
you to compensate for recordings made at too low a level. This page also allows you to
set your own level for gain re-scaling if you wish. You may process in mono or stereo
(although selecting stereo is pretty pointless if it's a mono sample!)
To normalise a sound, simply press
normalised version to be copied to, you will receive the prompt:
to which you must respond accordingly by pressing GO or ABORT. After a 'BUSY'
message, the new sample will be displayed showing the new level.
To re-scale a sample to a level of your own choosing, simply move the cursor to the
prompts if you haven't created a new sample to copy to and after a few seconds, you will
see the sample scaled to the value you set.
NOTE 1: Please be careful when using RESCALE because it is possible to overload the
unit if you set this value too high.
NOTE 2: Please also note that whilst normalise and rescale can save the day on many
occasions when you have recorded a sample at too low a level, it can increase noise
levels. For example, if the sample is very quiet, as you boost the level, you will also boost
the noise floor. Setting, for example, a rescale value of +15dB to bring the level up to
maximum will also boost the noise level by 15dB. Please bear this in mind when using
these functions.
