New

  • Remote API
    Remote API allows to share active and stored measurements data between different instances of Open Sound Meter. Also available for third party applications.
    For example, you can use iPad as a wireless remote for your main measurement setup.

  • Weightings
    • Added: A, B and C weighting filters
    • Added standard lines for weighting filters

  • Quick calibration
    94dB button in the measurement's properties sets measurement channel gain correlated to SPL 94dBA slow.

  • Level monitoring
    For multichannel monitoring of current sound pressure levels (SPL) or digital levels (dBfs) Level chart added

  • Digital meters
    SPL and dBfs values could be observed as the digital meters

  • Impedance
    Impedance mode added for the magnitude measurements. You can calibrate interface for your sensor resistance in see results in Ohms.

  • Burst noise

Improvements

  • Measurements
    • Allow negative delay values
    • Make impulse response time window equal to time frequency responses

  • Generator
    • Now it's possible to select many outputs channels
    • increase sweep period
    • Rase maximum frequency in the generator up to 192kHz

  • PPO
    • Added 1 point per octave option
    • Added PPO option for RTA line
    • Added PPO off option for RTA bars

  • Math Source
    • Added ability to use math source as a source in other math source
    • Added resulted impulse response to vectors functions

  • Interface
    • Add close button to popups
    • Reset charts height by double click on the divider
    • Step response extended limits
    • Impulse response extended limits
    • Enlarge popups for long titles (long channel names for example)
    • Cmd + 4 (Ctrl+4) shortcut apply auto height for the charts
    • Others small GUI improvements

  • Audio
    AudioSession (iOS) force set selected sample rate

Fixes

• Spectrogram reset ppo and binding loop
• Count for math source when cloned
• Spectrogram auto add sources
• Negative gain values in projects
• Others fixes

Optimisations

  • Lots of CPU vector instructions optimisations
  • Audio buffers allocation optimisations
