This gives a significant improvement over traditional stereo,
which converts the differences between the microphone signals
into amplitude differences in the speaker signals. This version of
the Trifield algorithm is virtually impossible to implement without
digital signal processing.
Trifield is recommended for well-made recordings and stereo
television broadcasts that are not Dolby Surround encoded. An
advantage over the Music DSP preset is that the front stereo
image is more focused, and the width of the image can be
adjusted.
