Dynamic range compression (DRC) or simply compression is an audio signal processing operation that reduces the volume of loud sounds or amplifies quiet sounds, thus reducing or compressing an audio signal's dynamic range.
The Sound Blaster Pro supported faster digital input and output sampling rates (up to 22.05 kHz stereo or 44.1 kHz mono), added a "mixer" to provide a crude master volume control (independent of the volume of sound sources feeding the mixer), and a crude high pass or low pass filter.
A significant increase in the effective volume of a closed-box loudspeaker can be achieved by a filling of fibrous material, typically fiberglass, bonded acetate fiber (BAF) or long-fiber wool. The effective volume increase can be as much as 40% and is due primarily to a reduction in the speed of sound propagation through the filler material as ...
