OmniMic 5.2 Whats New:

    • Improved impulse response peak finding
    • Much improved blend impulse response windowing, non-abrupt and now emphasizes activity earlier in the IR according to frequency and time position
    • IEC263 Standard graph format option for Frequency Response, for use in professional published reports
    • No longer requires WinXP emulation mode for proper SPL readings
    • Function to apply smoothing to all active Added Curves in one click
    • Now supports up to 40 Added Curves in Frequency Response for detailed polar data measurements
    • New keystroke actions: The [Space bar] Pauses and unPauses analyzer capture from the microphone. The [Enter] key brings up the menu for curve saves and Auto-polar-angle increment saves on Frequency Response tab. When capturing a series of Frequency Response measurements over a range of angles, just press [Enter] three times.
    • Loudspeaker SPL capability estimate features: IP2 (second order distortion intercept) and IP3 (third order distortion intercept) curve options in the Distortion Analyzer
    • Option for thicker distortion product curve traces in the Distortion Analyzer
    • Improved snaptshot filesave and print quality with better readability of characters
    • Perceptual ERB (Equivalent Rectangular Bandwidth) Smoothing option for Frequency Response curves to simulate sensitivity of human hearing to response smoothness
    • The shape of the Impuse Response window is now drawn on the Impulse Response graph in linear mode
    • Certain graphs settings and Frequency Response options are saved on closing Omnimic and restored on the next run
    • "Tail correction" tools provided for most accurately calculating minimum phase curves
    • Slightly more modernized graphics
    • Impulse Response synch fixed with MLS
    • Synch in Harmonic Distortion measurement fixed
    • Selection of white or color background working


Please note: Omnimic software will not work with other measurement microphones. Omnimic software is "married" to the serialized calibrated Omnimic hardware. Software download is for Omnimic users that have lost or need to upgrade their software to the latest version. Should you have any questions or installation issues please contact Dayton Audio support or your place of purchase.

OmniMic V2 Measurements:

• SPL meter with A, B, C, or no weighting
• Spectrum analyzer, FFT, or RTA
• Frequency response with phase and impulse response
• Oscilloscope function to view complex waveforms
• Harmonic distortion: 2nd, 3rd, 4th, 5th harmonics plus THD
• RT60 reverberation: measures sound reflection
• Bass decay function identifies room modes and helps determine proper subwoofer placement
• Polar Plotting, in flat or 3D radar format
• Wavelet Spectrogram (color) to the Waterfall group
• Curve Math for live or added curves
• Auto-naming of repeated FRD measurements; updated
• Snapshots to PNG, BMP, JPG or WMF formats
• Measurement down to 5 Hz
• Energy-Time Curves, with configurable band limiting
• Supports new file-based microphone calibration
