Multi-Band
Compression
One of the
available compressors in Sound Forge 7 is a multi-band
compressor, with 2 bands. Each "band" restricts the
compression to a particular frequency range that can be set by
the user. The most-often used configuration is where the
mastering engineer will use one band to compress the bass
frequencies and the second will compress the midrange and
treble frequencies. With the proper setup of the
compression bands, virtually all breathing by the
compressor can be eliminated. Breathing is when you will
hear the level change on high frequency instruments (or
noise) caused by level changes of lower-frequency
instruments. You will begin to hear noise changes
(especially on analog recordings) and erratic levels on
high-frequency instruments when too much compression is applied. |
