Chapter 1 – Introduction
Introducing Waves Linear-Phase MultiBand Processor.
The LinMB is an evolved version of the C4 MultiBand Parametric Processor. If
you are familiar with C4 you will find the Linear Phase MultiBand very similar,
adding some true breakthrough innovation and technology that yields superior
and purer results.
The LinMB has -
• 5 discrete bands each with its own gain and dynamics for equalizing,
compressing, expanding or limiting each band separately.
• Linear Phase crossovers allow true transparency when the split is active
but idle. The only effect is pure delay with no coloration of any sort.
• LinMB is equipped with the options for Automatic Makeup and gain Trim.
• Adaptive threshold behavior achieves most effective and transparent
multiband dynamics processing.
• LinMB has the visual interface of the award winning C4 with Waves’
unique DynamicLine™ display showing the actual gain change as an EQ
graph display.
Waves created the LinMB to answer to the most demanding and critical
requirements when Mastering any sound and genre of music.
While the Waves Masters bundle is focused to provide purist quality tools for
Mastering, there are many applications in which it may be very useful i.e.
Vocal processing, Transmission processing, Noise reduction, Track Strip.
The LinMB has a fixed amount of delay or fixed latency of about 70ms (3072
samples in 44.1-48kHz). Due to the intensive calculations required for the
Linear Phase crossover it is quite an achievement to have this work in real-
time in both TDM and Native. Much effort was put to optimize the
performance for specific CPU’s using Co processors such as Altivec on MAC
and SIMD on x86 type processors. Processing higher sample rate such as
96kHz will definitely require much more CPU then 48kHz.

In MultiBand Dynamics processing we split the wide-band signal to discrete
bands. Each band is sent to its dedicated dynamics processor to apply the
desired dynamic gain adjustment or static gain. Splitting the signal has
several major consequences as follows:
• Eliminates Inter Modulations between bands.
• Eliminates gain riding between different frequency bands.
• Allows setting each band’s attack, release times scaled to the frequencies
in that band.
• Allows setting different functionality (compression, Expansion, EQ) per
each band.
For example, its possible to compress the low frequencies with longer attack
release values, at the same time expand the mid range with shorter ones,
DeEss hi-mids with much faster attack and release and boost the super hi
frequencies without any dynamics.
