While t his may not result in t he loudest sound, it gives the illusion of competitive loudness wh ile still retainin g a lot of detail and clarity.

The last option, adjusting the Mixer , is d esigned to provid e a final minor trim to the audio spect rum. Since this stage is after all of the dynamic multi-band AGC and Peak Limiting, a radical change in level in the Mixer could result in excessive look-ahea d final lim iting in that band’s fre quency range. We suggest that a ny changes im plem[...]
