SuperBass

Description


The Super Bass block is a bass enhancement algorithm specifically designed to compensate for the poor low end response of small speakers by using psychoacoustic principles to improve the perceived bass response.

Variants

  1. Super Bass (Mono)
  2. Super Bass (Stereo)

Configurable Parameters

GUI Parameter NameDefault ValueRangeFunction Description
—————————————- ———————- —————— —————————————-
Intensity 1.3 0.1 to 3 Controls how much gain is applied to the artificially generated higher harmonics(Above cross over frequency).
BassGain 1.2 0.1 to 3Controls the gain applied to the input signal below the cross over frequency
XOverFrequency 90 Hz 20 to 500 Hz The signals below this frequency are considered to be in the bass range. These signals will be used for the bass enhancement algorithm. Higher harmonics of these signals will be generated above the crossover frequency, giving the impression of increased bass.
Bypass_ON True True/False Activates or Bypasses the algorithm
