Multichannel Encoder
The latest version of Cool Edit Pro includes the Multichannel Encoder. This is a self-
contained dialog where you can access the tracks of any existing CEP 2 Multitrack
session. In the Multichannel Encoder dialog, you can individually pan each track to your
multichannel setup, preview the current mix and then Export the session as an encoded
WMA Pro version 9 Multichannel file. It is also possible to export your session as 6 Mono
Wave files or as one interleaved 6-channel Wav file for use with an external Multichannel
Encoder such as a Dolby or DTS encoder.
CEP 2.1 Multichannel Encoder Requirements
To achieve proper “5.1 Surround” preview playback from the Multichannel Encoder, it is
necessary to meet the following requirements:
1) A sound card installed and selected that offers at least 6-channel analog output,
as well as a special interleaved device driver that is compatible with the Microsoft
DirectSound multichannel format.
2) Microsoft Direct X 8.0 or later installed
If your PC does not meet these requirements then you may receive a warning dialog,
and your Play Track and Play All buttons will not be accessible.
To be able to Export and Encode your project to a 6-channel Windows Media file, you
must have the Windows Media 9 runtime installed. If you have an earlier Windows
Media version on your PC, the Encode to WMA9 option will not be available.
The latest Direct X and Windows Media Updates are available on the Microsoft website.
To use the Multichannel Encoder, first open an existing Cool Edit session, or create a new
session in the Multitrack window. Once all your tracks are added, you next want to achieve
a basic stereo mix balance with your desired track volume, stereo pan and FX settings.
Then launch the Multichannel Encoder from the View menu. Below is a description of the
elements found in the Multichannel Encoder:

Track List
At the top left of the dialog is the track list. This list will show all the tracks and buses in use
in the current CEP multitrack session. You select which tracks and/or bus outputs you
want to be included in the multichannel mix by checking the box at the left of each track.
Any track that is unchecked here will be removed from the multichannel preview and will
not be included in the Export of the multichannel project.
Panning Tracks and Buses separately - Note that if you have routed a track’s output to a
bus in the Multitrack that you will likely not see that track appear in this track list. Instead,
the bus that the track was assigned to will appear in this track list, and the bus output
(which consists of all track signals routed to that bus) can be selected and panned as one
mono or stereo signal. Additionally, it is also possible to access the “dry” track signal and
pan it separately as well. This is achieved by going into the CEP bus tab at the left of the
track, or into the CEP multitrack Mixer Window, switching to the Bus Mixer tab and
adjusting the balance of the wet and dry values. Once the dry value is set greater than 0,
this creates a selectable track entity that will appear in the Mulitchannel Encoder Track List
the next time you launch it.

For an example, consider that track 1 of a session consists of a vocal wav file. You might
have several other vocal tracks in this session as well and therefore you might add one
Reverb effect on Bus A and set each vocal track’s output to Bus A to have all be effected
by this Reverb. But for track 1 you might wish to achieve a different surround panning
effect where a non-effected track signal is panned to the front channels, while the effected
bus output signal is sent only to the rear surround channels. If you set the track 1 bus wet
and dry values each to a value such as ‘50’ then you will be able to pan these two signals
separately. Once these settings are all made within the multitrack session, launch the
Multichannel Encoder dialog and you will then see that both “Track 1” and “Bus A” are
available as selectable entities that can be panned individually. This type of routing can be
very useful for adding ambience and dimension to your multichannel mixes.
To perform panning adjustments on any track, select any one track in the list by clicking on
the track name so that it becomes highlighted. For example, the VocodeStinger track is
selected in the following example:
Surround Panner interface
Center
Front Left
Front Right
Panner Point
Left Surround
Right Surround
Low Frequency Effects (Sub Bass)

The Surround Panner allows you to position the selected track anywhere in the main
speaker sound field by left clicking and dragging the white “Panner Point”. Note that as you
position the Panner Point within the circular sound field the light blue “Power Indicator”
lines coming from the speakers will change in length. This indicates the power balance of
your sound source coming from each of the five main channels. Additionally, a portion of
the sphere will appear dark blue in color to indicate the image of the sound field. That is,
when seated in the center of the speakers, the blue area indicates where the listener
would perceive the sound coming from.
You can also drag the Panner Point outside the sound field directly on top of one of the
five main speakers or on top of the LFE speaker. Once the Panner Point is in any one of
these speaker locations, the audio from the currently selected track is summed to a mono
signal and sent discretely to this one speaker channel. This is an easy way to send the
complete track signal all to one channel.
Panning Assignment Selector
At the top right of the dialog is the Panning Assignment selector where you can choose to
either use the Panning Interface to position your track sound source, or to make ‘fixed”
panning assignments for your track. To follow is a description of each of the options in this
list:
Surround panner, stereo source
This option allows you to use the Panning Interface to position your sound source by way
of dragging the Panner Point to the desired position. It also keeps your stereo left and right
signals from your track discrete when panning in the sound field. For example, if your track
includes a stereo file, the left stereo signal will be sent to the Front Left and Left Surround
channels, your track’s right signal will be sent to the Front Right and Right Surround
channels. The Center channel always receives a summed to mono (L + R) signal.
Therefore, as you pan in the five channel sound field, these stereo sources will retain their
“stereo image” while being routed to the multiple channels.
Surround panner, summed to mono
This option allows you to use the Panning Interface to position your sound source.
However, this option always sums the track’s signal to a mono signal. In this mode,
panning the sound source to any location in the sound field will result in the summed mono
signal being fed to all channels.
