Some sound cards work with software that provides additional voices.
A wavetable sound can be enhanced or modified using reverberation or other effects before it is saved in the table. Some wavetable chips include a special section for drum sounds to support rhythmic effects. Many also include an FM synthesizer in order to play back sounds from older applications or files . Full-duplex data transmission means that data can be transmitted in both directions on a signal carrier at the same time. A wavetable is a table of stored sound waves that are digitized samples of actual recorded sound.
