SmaartLive? Version 5, SIA Software Company's dual-channel FFT-based audio measurement software, is the professional audio industry standard for real-time sound system measurement, optimization, and control. SIA's SmaartLive software for Microsoft« Windows« combines powerful audio frequency measurement, analysis and data logging capability with a highly intuitive, user-friendly interface and the ability to remotely control an extensive list of top name equalizers and DSP processors. SmaartLive Version 5's Measurement Capabilities Include: Spectrum: Real-time signal analysis with multiple, simultaneously viewable, measurement modes: 2-channel RTA with selectable linear or fractional-octave banding (to 1/24-octave), peak-hold and THD calculation functionality as well as user-definable timed averaging. Standard Noise Criterion (NC) curves available when calibrated for SPL measurement. Single channel Spectrograph - a powerful 3-D display of a signal's spectral content over time and an excellent tool for identifying feedback frequencies and other persistent frequency-dependent problems such as system resonances and mechanical noise. Sound Pressure Level (SPL) measurement with user definable alarm levels. When calibrated for SPL, SmaartLive provides a continuous SPL readout with Flat, A and C weighting options and standard Fast and Slow integration times, as well as the option to display an SPL histogram with Max, Min and Avg. values over the measurement period. Spectrum Data Logging: Spectrum measurement data logged to a user-specified file in time-stamped, tab delineated ASCII format. This feature supports user-definable sampling integration times from one second 24 hours in length and total measurement durations of up to 1 week (168 hours). LEQ calculation functionality included. LEQ (Including L10, L50, L90, LMin and LMax) Spectrum Log (Fractional Octave Data to 1/24th) SPL Log Transfer Function: Provides precise dual-channel frequency response measurement using any test signal - making it possible to monitor a system's behavior during a performance or event, using the actual program material as the test signal. Features include: Magnitude, Phase and Coherence data traces for all live and stored Transfer Function measurements. User-definable Magnitude and Coherence Thresholding functions to reject bad or suspect data. User-definable time windowed transfer function Calculated EQ curve displayed with external device control interfaces. RMS and Vector Averaging Options Impulse Response: Precise delay time and system acoustic response measurement capability - SmaartLive can measure the arrival times of signals with up to 0.02-millisecond resolution (depending on sampling rate), essential information for achieving (and maintaining) optimal alignment of sound system components and subsystems. Features include: Store and recall Impulse Response measurements in Windows .wav file format. Store and compare measured delay times. Mouse Line Draw on Plot with T60 calculation. Log Scale, Linear Scale and ETC views Note ID: Cursor available in Spectrum and Transfer Function modes that indicates the nearest musical note corresponding to a frequency from the standard 12-tone scale, a useful feature for helping bridge the communication gap between engineers and artists. External Device Control: Remote control capability for over 40 pro-market equalizers and DSP processors from manufacturers such as Ashley, BSS, dbx, Klark Teknik, RAMSA, Sabine, Shure, and XTA, allows you to identify and address sound system issues from a single screen without need of switching to another control program or reaching for the rack. All device capabilities, including EQ, delay, gain, limiting and crossover settings for each device included in its interface as well as the calculated response curves shown with magnitude traces in Transfer Function mode. Weighting Curves: Standard A, C and user-definable weighting curves available for application in Spectrum and Transfer Function modes. Internal Signal Generator: Use your internal wave output to generate standard measurement signals including: pink noise, sine wave, dual sine and looped wave (*.wav) files. Also available are four FFT length-specific synchronized (sync) measurement signal sources: pink sync, red sync (red = extra LF energy), pink sweep and red sweep. Configurations and Presets: Extensive flexibility for interface and measurement configuration enables you set up, store and quickly recall analyzer configurations and measurement presets that make sense for the way you want to work.
