Room-Capture

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 maximumlength sequence (MLS) stimulus, Sweep Tone (time-domain chirp) or Dual FFT (using external Wavefiles) to the loudspeaker or sound reinforcement system under test. Room-Capture also offers a multi-channel Real Time Analyser with up to 1/24 octave resolution. For room tuning and sound reinforcement system optimization, sophisticated windowing functions allow the user to window out room reflections from individual measurements and focus on equalizing the direct sound while retaining low frequency resolution. Room-Capture also supports spatial averaging, allowing 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. 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. Room-Capture also introduces a novel
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.
