Creating Your Project
When you first open Impulse Response Utility, you will be presented with the New
Impulse Response Project dialog window. This is the first step in creating a new
impulse response project. You can also create a new impulse response project by
choosing File > New Project (or pressing Command-N).
Impulse Response Utility offers formats ranging from conventional stereo impulse
responses, true stereo (where each channel is processed discretely) and quadraphonic
formats, to five, six, or seven channel surround formats. These latter formats can be in
either: traditional multi-track, or B-Format encoding. Please see “
B-Format Surround
Encoding ” on page 28 for more information.
You can also create multi channel impulse responses in Impulse Response Utility by
using the Mono to Omni Discrete impulse response format. This only requires the
recording of one speaker by as many “channel” microphones as needed (for the chosen
format). The resulting impulse response places a lower strain on your CPU. See
“
Recording a Mono to Omni 5 Channel Impulse Response ” on page 32.
To create a new impulse response project:
1 Choose the desired impulse response format from the Configuration menu.
In the window below the Configuration menu, the dialog displays the number of
speaker and microphone positions required by the selected format.
2 Click OK
This exits the New Impulse Response Project dialog, and the required number of tracks
(determined by the format you chose) are shown in the Inputs/Track section.
