QSizzle self-adjusts in real time according to frequency response of the input signal. This is different
from the Equalizer, which is a fixed frequency processor. The Equalizer does not monitor the input
signal or perform self-adjustment. The label QSizzle Active appears in illuminated text when
QSizzle is enabled, and QSizzle Off when disabled.
3.3.2.2. QRumble
QRumble is a powerful low frequency enhancement algorithm that helps to compensate for loss of
bass that may result from digital file encoding such as ripping MP3’s or WMA files, or when using
lower quality speaker systems.
QRumble responds in real time to the varying nature of the input signal, automatically adjusting itself
accordingly. This is very different from the Equalizer, which is a static frequency processor. The
Equalizer does not monitor the input signal or perform self-adjustment.
The label QRumble Active appears in illuminated text when QRumble is enabled, and QRumble
Off when disabled.
3.3.2.3. Normalization
Normalization automatically adjusts the volume variations in various audio files or streams. Quieter
signals are amplified to match the level of louder ones, so that the listening volume maintains a
consistent level. This means that when playing files with various output levels, constantly adjusting
your speaker volume becomes a thing of the past.
The label Normalization Active appears in illuminated text when Normalization is enabled, and
Normalization Off when disabled.
3.3.2.4. 3D Effects
The goal of 3D effects processing is to maximize immersion and realism for any type of listening
material and every type of output hardware – two or more speakers, headphones, or even the
unique combination of speakers with headphones.
Four separate 3D audio enhancement algorithms are provided to maximize the spatial experience
no matter what the combination of signal type and output hardware.
When 3D Effects are enabled the audio processor will automatically choose the appropriate
algorithm (3D mode) according to your output configuration and the type of input signal. The 3D
Effect indicators on the Effects Tab light to show which algorithm is active at any given time.
QXpander is optimal for 2-channel (stereo) input played over 2 speakers (or 2 satellite speakers plus
a subwoofer). QXpander provides a wider sound field, way beyond the physical position of the
speakers
QSurround is optimal when a multi channel source is played (e.g. a 4.1 channel DVD). QSurround
optimizes the sound to create “virtual” speakers and immerse the listener in surround sound.
QMSS is optimal for multi-channel speaker set-ups (4 or 4.1 channel) when a stereo source is used.
The majority of sources are stereo (e.g. MP3’s, CD music tracks, Wave files, etc) and QMSS
transforms these into immersive multi channel experiences with 4 or 4.1 separate channels
depending on your speaker set-up.
