BRICKWALL HD User Manual
1. Introduction
Congratulations on the purchase of your BRICKWALL HD True-Peak Limiter.
Over the past two decades, as the Loudness-Wars have raged, it has become clear
that the abuse of “loudness maximizers” in mastering can significantly reduce
the audio quality for the listener.
When levels get squashed against the 0 dBFS digital ceiling, then reconstructed
intersample-peaks in Digital-to-Analog converters and audio file codecs (for
example MP3 and AAC), may be higher than the level that consumer equipment
was designed to handle. We call this level “0 dBFS+”, and often there have been
no limiters in music mastering preventing such peaks from happening.
The limiters in the BRICKWALL HD are designed to:
• •
Continually measure if your signal contains 0 dBFS+ peaks
• •
Then gently remove them
The BRICKWALL HD is a transparent and upsampling True-Peak Limiter that is
tightly based on the award-winning BW2 algorithm from TC’s System 6000. This
is an algorithm that for the last 2 decades has proven its worth on countless high-
profile records, feature-films etc.
In the BRICKWALL HD, we have:
• •
Refined the workflow to include modern music streaming targets
• •
Developed more options on Softclipping
• •
And not least, added a new History view that gives in-depth information and
assists you in making the crucial master track decisions.
Two alternative types of Limiter are provided in one:
• •
The conventional Master Limiter
• •
The novel Loudness Limiter
The Master Limiter is a typical approach, with Input Gain to set the amount of
limiting, and Ceiling to set the amount of headroom in the exported file.
The Loudness Limiter is an all-new approach, enabling a workflow suitable for
modern streaming services like Spotify, Tidal, and Apple Music. Here you set a
desired, resulting loudness level, which the BRICKWALL HD will automatically aim
for after listening to your track.
Both Limiter types include a flexible and delicate SoftClipper that has three
available options from soft, smooth, to hard.
The BRICKWALL HD’s combination of True-Peak and Loudness numerical
information (STATS), provides the best possible support for making optimal
decisions of dynamics, head-room and loudness level in your precious mix or
master.
As a further aid, Loudness Range (LRA) and Peak-to-Loudness (PLR) read-outs
provide a tangible indication of how much dynamic compression and limiting you
are applying prior to, and with, the Limiter.
But remember, ultimately, your ears are the best tool you have.

For mastering in the DAW we recommend the MASTER X HD (3 band Expander,
Compressor, Limiter) plug-in in combination with BRICKWALL HD. There are
optimized preset “pairs” included in the plug-ins to get a head start.
For mastering in a separate and highly optimized environment we recommend
the Finalizer application
