296 Chapter 11 Sample Editor
The Attack and Release parameters control the steepness of the algorithm’s filter. You
can try increasing these values to double or four times the default, if the result sounds
too “digital” or “raw”. This can happen if small elements among the main events in the
original signal are boosted. As an example, the reverb portion of a sound can become
louder.
The perceived loudness of the overall audio material is increased. If the material
contains anomalies such as noise, these will also be increased, and sometimes become
audible. If necessary, you can edit the result with the noise reduction function (Silencer)
on a low setting, or make use of Logic’s effect processing capabilities.
Sample Rate Converter
The Sample Rate Converter is used for sample frequency conversions.
Opening the Sample Rate Converter
Normally, you’ll want to convert the sample rate of an entire audio file. To do this, select
the whole audio file in the Sample Editor (Command-A).
Select Factory > Sample Rate Convert, and click the Convert button.
Parameters
Source (Hz)
This shows the previous sample rate of the audio file. To enable changes to incorrectly
stored sample rate formats (after editing in other programs, for example)—or for
effects—you can enter any value you like here. You should only change this parameter
if you know what you’re doing.
Destination (Hz)
Enter the desired sample rate that you want the selected area converted to.
