Capturing a signal to tape or disk clean of excessive reverberation or noise is critical. You can always add effects later to enhance or alter a sound, but it is difficult to remove distortion and noise from the original source. Compression in the encoding process also degrades your sound slightly. The higher the quality of the original source material, the higher the quality of the final output to the Web. In addition to selecting the right equipment, properly setting up your studio and reducing noise on location also results in a cleaner signal.
