The DMS2Five plug-in is made
with SonicBirth, a visual
dataflow programming language for the
creation of Audio Unit and VST
plug-ins for Mac OS X. The
Windows OS equivalent of SonicBirth would
be SynthMaker.
The DMS2Five plug-in, and the
information on this page, are provided as
is, without any guarantee regarding
performance or end result. Ambisonic

X Lossless Decoder (XLD):
utility for converting files between the following
formats: Wave, AIFF, raw PCM, Wave64 (.w64),
MPEG-4 AAC (.m4a), Apple Lossless (.m4a),
FLAC (.flac/.ogg), MP3, Ogg Vorbis,
WavPack (.wv). Can also read
Monkey's Audio (.ape) and True
Audio (.tta). Files can be multichannel if
supported by file format.
The DMS2Five has six inputs, M-Front, S and
M-Back (plus three dummy inputs for compatibility
purposes), and three different 5.1 output modes.
Input Trim Controls
To adjust the individual input levels of the three
microphones. The DMS2Five is adjusted to the
different sensitivities of the CCM 4V and CCM 8, but if level
discrepancies occured in the recording, they can
be compensated by up to 6 dB. A good practice with
a Double MS assembly is to globally adjust the
recording levels (not individually per channel) to
maintain the level relationship between channels.
Front/LR Channel Controls Level: to attenuate the output by
up to 24 dB, the default is 0 dB or no
attenuation. Directivity: to control the
directivity of the virtual microphones feeding the
speakers between omnidirectional and
figure-8/bidirectional (default to 0.5,
cardioid/unidirectional). Width: to vary the width of the
speaker feeds from 0 to 180°, with default to 60°,
referenced to Center. Mute: to mute the output, with
default to Off, meaning no mute.
Center Channel Controls
Level: to attenuate the output by up to
24 dB, the default is 0 dB or no
attenuation. Directivity: to control the
directivity of the virtual microphone feeding the
speaker between omnidirectional and
figure-8/bidirectional (default to 0.5,
cardioid/unidirectional). Mute: to mute the output, with
default to Off, meaning no mute.
Sub/Lfe Channel Controls Level: to attenuate the output by
up to 24 dB, the default is 0 dB or no
attenuation. EQ: to control the lowpass filter
between 20 and 160 Hz with the default at
120 Hz. Mute: to mute the output, with
default to Off, meaning no mute.
Surround/LsRs Channel Controls Level: to attenuate the output by
up to 24 dB, the default is 0 dB or no
attenuation. Directivity: to control the
directivity of the virtual microphones feeding the
speakers between omnidirectional and
figure-8/bidirectional (default to 0.5,
cardioid/unidirectional). Width: to vary the width of the
speaker feeds from 180 to 360°, with default to
240°, referenced to Center. Delay: to delay by up to 35
milliseconds with a default of 0 ms or no
delay. Used for augmenting Front-Back separation. EQ: to control the lowpass filter
between 1 kHz and 20 kHz with the default at
20 kHz. Used for augmenting Front-Back
separation. Mute: to mute the output, with
default to Off, meaning no mute.
Soundfield Controls Axis Flip: to flip the soundfield
on the Front/Back axis (front becomes back) and on
the Left/Right axis (left becomes right), both
default to Off, no flip. Rotation: to rotate the
soundfield, in degrees, from -180 to + 180.
Default to 0°, no rotation.
Interpolation Control
Affects the sound quality of the Surround Ls/Rs
delay. The Linear interpolation setting will yield
better sound quality, but will use more CPU.
Default to No interpolation.
Outout Channel Order Control
Configures the output channel order. This can be
useful in preparing the audio stream for
applications that expect the audio channels in a
specific arrangement. Apple Logic users should
select the third option:
L R Ls Rs C Lfe.
Mute unused channels to optimize CPU performance.
Note on the Sub/Lfe: activate
the Sub/Lfe when monitoring without bass
management. Deactivate (Mute) it when generating
the actual stream for the 5.1 media: the DMS2Five
will then output a 5.0 stream, but the media
player/surround processor will likely feature bass
management if the 5.0 stream is delivered on
DVD-Video, DVD-Audio, DTS-CD, SACD, HD-DVD,
Blu-ray disc or HDTV broadcast. More details on
the use of the Lfe channel available here.
