PCM Effects and Parameters

Football
The Football Effect uses a reverberation algorithm, which differs from
ambience in that it does not simulate the reflections of specific halls, but
emphasizes rich, smooth reverberant decay in small and medium
spaces. It works well for simulating a space with a long reverberation
time relative to its size, and for simulating the sound of a live sporting
event.

Classical
The Classical Effect generates the appropriate early reflections for
stereo simulation of many different halls, and sends the reflections to all
channels in addition to the direct signal in the main speaker. This Effect
is not appropriate for highly percussive music.

Cathedral
The Cathedral Effect uses a reverberation algorithm which emphasizes
rich, smooth reverberant decay in large spaces. As its name indicates,
it works well for simulating a space with a long reverberation time
relative to its size, such as a cathedral.
