choosePreset preset-number [int]
The word choosePreset, followed by a number in the range 0-2, selects a preset for the omx.4band~ object. These presets are to be considered "starting points" and should be tweaked for your particular purpose or desired sound. The preset options are:

0: Universal - Provides a general boost to the sound, with a 3-to-1 compression and no limiting. Bass enhancement is switched in for a bit of warmth.
1; Pop - Sets a 50:1 compression with hard driven limiting in the lowest two bands. The gives a solid bottom to the sound.
2: Hit Radio - Is a compromise between the Universal and Pop settings. You will note that the times are all about the same, with appropriately slower attack and release in the low bands.
3: FM Radio - Differs from the Pop and Hit radio settings primarily in the high end, which is compressed a bit tighter.
