The solution

We’ve solved the issue described above for you by creating an algorithm that reacts in the same way as a

normal sound engineer would do, hence the name ‘Engineer’. The Engineer works with human-based

perceptive algorithms which react the same way as a normal human being would. This means that the

algorithm reacts to perceived loudness instead of electrical loudness, so that songs with a lot of compression

(which sound loud), will be turned down more than more dynamic songs, so that the overall perceived level

stays intact.

The Engineer algorithm features an automated volume control, an automated low EQ, an automated high EQ

and a multiband end-stop limiter to catch extreme peaks in the program material.

Just like a normal human being would, the algorithm listens to the incoming signal for a couple of seconds,

then decides if it sounds too loud or too weak, adjusts the volume, listens to the amount of bass and treble in

the material and, if necessary, changes it.

If the volume of the material has a sudden large boost in volume (for instance when a DJ is fooling around),

these peaks will be handled by the end-stop limiter so that the algorithm has the time to slowly lower the

volume.

The picture below is the output of the engineer algorithm with our example input. In this picture we see that

the level and tone differences have been solved in an elegant way without destroying the dynamics or adding

distortion, and that the last piece of heavily compressed music has been lowered in volume to give it the same

perceived volume.

Engineer advanced configuration

The default Engineers settings give a good general purpose operation but all operational parameters can be

fine-turned in the Advanced tab to match the operation to a specific style of music or whatever response you
