Room-Capture
Everything you need for tuning and document a room
or an arena. Incorporates powerful post processing
of ISO quantities and IEC STI. Two-and three-dimensional Waterfall and Wavelets analysis are included.
Room-Capture is a powerful PC-based software tool that is ideal for room
tuning, sound reinforcement system optimization and room acoustics
analysis.
Room-Capture acquires complex frequency response by applying either a
maximum length sequence (MLS) stimulus, Sweep Tone (time-domain chirp)
or Dual FFT (using external Wavefiles) to the loudspeaker or sound reinforcement system under test.
MultiWin
Sophisticated windowing functions allow the user to window out room reflections and focus on either equalizing the direct sound while retaining low
frequency resolution or spatial averaging of the room transfer function.
Pseudo Averaging
Room-Capture also supports Pseudo Power Averaging, which recreates an
average of the time response. PPA allows the user to perform a series of
measurements throughout the coverage pattern of the sound reinforcement
system and base system EQ on the weighted, spatially averaged response.
Equalizer simulator
Any captured transfer function can be run through an optimization algorithm
that produces a list of parametric EQ parameters (Frequency, Q and Gain)
that are required to fit a user-defined target curve. For further optimization
EQ parameters can be manually fine-tuned using a convenient graphical user
interface. A list of created filters can be transferred to a DSP device or the
resulting filters can be listened to or used as stimulus EQ.
Listen to filters
You can use your PC’s multimedia core to run up to 256 parametric filters or
any bi-quads (shelving, x-over filters, allpass etc.) through your soundcard.
You can listen to .WAV files from your hard-drive or assign an input of the
soundcard to feed the filters with any program material. You can measure
with the filters applied on the stimulus, so you can check your filter setup on
and off axis for example.

Room Mode finder
Automatic Room Mode finder with automatic calculation of parametric EQ that
can be used to remedy dominant room modes or for optimization of installed
Helmholz resonators.
Real Time Analyzer
Room-Capture also offers a multi-channel Real Time Analyser with up to 1/48
octave resolution. Besides industry standard FFT based RTA, a high-resolution
low frequency band-pass mode is introduced.
Presets
saves your settings for the stimulus and analyzer. A range of useful settings is
provided for different applications.
GUI
Much effort is put in the new user interface to reduce the need for dialog
boxes and spin-boxes. These are replaced with modern mouse wheel and
grab ‘n’ drag mouse based controls. For example if you need to change the
range of a graph, this is now done with the mouse wheel. Dragging the scale
makes zooming.
Waterfall 3D and 2D display
Wavelets are considered as more hearing-like frequency-time analysis than
traditional Spectrogram. Wavelets offer the same frequency resolution,
i.e. constant relative bandwidth, but increased time resolution at higher
frequencies.
Wavelets are useful for room acoustic analysis such as diffuser tuning, loudspeaker driver time domain analysis and system analysis of time smearing.
X-over aligner
This is the quick way to fine-tune the levels and delay between bands in a
multi-way active system. The X-over Aligner offers an intuitive graphical aid
for delay alignment with synchronized time and frequency graphs. A range of
useful curves can be displayed such as Impulse response, ETC or Cepstrum
in the time domain. In the frequency domain both group-delay and wrapped
phase can be chosen, depending on the preferred alignment strategy.
The X-over Aligner also offers two automatic delay finder algorithms.
Quantities
Added background noise measurement and considering background noise in
the STI calculation. Considering Masking in the STI calculation is a new feature. Improved Noise Correction and regression line algorithms for reverberation time calculations.
