Main Features of System-eye: β’ Dual-Channel FFT Sound System Analyzer: Tailored for live audio engineers, capable of real-time measurement of sound system frequency response. A tool for sound system EQ and optimization. β’ Frequency Response Measurement: Offers real-time assessment of the system under test by displaying live magnitude and phase over frequency through adjustable plots. β’ Coherence Measurement: Provides validation for Frequency Response measurements. β’ Impulse Response Graph: Displays time representation of system response. Provides a better temporal evaluation of the overall response and serves as a reference for Auto Delay feature. β’ Averaging and Smoothing Capabilities: Enables users to quickly grasp their sound system by highlighting either the overall trend or the finer details that contribute to the response, both in time and frequency. β’ Audio Input Connection: Requires an external audio interface with dedicated inputs for measurement microphone and output for a reference signal. It can use Y-split or internal programmable split inside the audio interface. β’ Auto Delay Function: Automatically detects the delay between the microphone and the reference signal, essential for accurate measurements. The Auto Delay feature, however, does not impede usability and can be turned off, allowing users to manually adjust the delay as needed. β’ Signal Generator: Generates pink noise as a stimulus for measurement, with adjustable gain, on/off status, and destination. β’ Trace Management: Captures and stores measurement traces for future reference, with options to evaluate, rename, color, and delete. β’ Keyboard Shortcuts: Quick access for starting/stopping analysis, toggling live trace view, and showing/hiding various plots (Impulse Response, Phase, Coherence). β’ User-Friendly Design: Simple and lightweight, catering to the core needs of experienced engineers.
