Main Screen

The main screen shows the live feed of each module.


Real Time Analyzer

  • The Real Time Analyzer displays the live XY plot for dB level vs. frequency.
  • The Global Settings allows you to choose block size, spectral weighting, and display colors for the graph.
    • The Block Size will default to 2048, but can be adjusted from 256 to 16384. This determines the amount of data allowed to buffer before being processed. The larger the buffer, the more accurate the values will be. However, the larger the buffer, the more the device has to work. If you experience trouble processing on your device, try decreasing the Block Size. If you want more detail, increase the block size.
    • Spectral Weighting: in the Global Settings menu, you can choose between Flat, A, B, and C weightings.
    • The SPL or dBFS buttons allow you to choose between the two options. If you want to see the digital value from 0 that the device is receiving, select dBFS; otherwise, keep it on SPL to know how loud your environment is.
    • The Spectrum Color option lets you choose to display the RTA in spectrum color or solid blue.

dB Meter

  • The upper left of the cube shows the Max value based on the greatest dB value heard until the Reset button is pressed. You can choose to display Max–Peak or Max–Average in the settings menu.
  • The upper right of the cube displays the Average sound level over the last second, minute, or 5 minutes depending on the value selected.
  • The bottom section is the Peak value.
  • You can also select between Fast or Slow time weightings to the left of the cube.
  • In the Global Settings menu, there are a few options.
    • The Block Size will default to 2048, but can be adjusted from 256 to 16384. This determines the amount of data allowed to buffer before being processed. The larger the buffer, the more accurate the values will be. However, the larger the buffer, the more the device has to work. If you experience trouble processing on your device, try decreasing the Block Size. If you want more detail, increase the block size.
    • Spectral Weighting: in the Global Settings menu, you can choose between Flat, A, B, and C weightings.
    • The SPL or dBFS buttons allow you to choose between the two options. If you want to see the digital value from 0 that the device is receiving, select dBFS, otherwise, keep it on SPL to know how loud your environment is.
    • AcoustiTools has been properly designed and calibrated to work with the microphones on iPhones and iPads. However, AcoustiTools includes the ability to adjust the microphone calibration trim in 1 dB increments.

Augmented Reality Spatial Module

  • In the Spatial module, you can use the advanced augmented reality technology to see spatial acoustic information.
    • Place tags to see the audio information at each tagged location.
    • To place tags, tap the plus button at the lower right of the screen.  Line up the speaker icon on the floor directly beneath the speaker and tap the plus button again to lock the icon to that location along the floor.  Then, tilt your device up until the speaker icon is on your speaker and tap the plus button one more time to lock the speaker icon in place.
    • Tag your main speakers to see the volume at each speaker's location.
  • The Volume Variance feature displays the volume over the audience between the main speakers and your device.
    • To use this feature, label your main speakers.
    • To label the tags as mains, press and hold the Main Speaker button until the center of the reticle is over the speaker icon you are labeling.  When the reticle is over a tagged speaker, the reticle will highlight by filling the center of the reticle's ring.  Once the reticle highlights, release the button and the speaker is now labeled as a Main Speaker.
    • Now you can click on the Volume Variance button to view how loud the volume is from the front of your audience to your device and make sure the experience is great for everyone.
  • The Delay Calc feature uses speaker tags to quickly calculate the delay timing needed for setting up your delay stacks. The Delay Calc view shows the distance between the tags and the time that sound will take to travel between them. You can input this value into your system and then adjust the value further according to the Haas effect range for your specific venue.
    • To use this feature, place two speaker tags: one for a main speaker and one for a delay stack on the same side of the venue.  Label both speaker tags with the Delay Tag button using the reticle highlighting process.
    • Now you can click the Delay Calc button to view the delay calculation.

Diagnostic PEQ

  • The revolutionary Diagnostic PEQ module diagnoses your audio and recommends a corrective EQ curve in real-time.
  • Values are displayed for the center frequency, the Q, and the amplitude.
  • You can switch between Active and Paused modes within the module.
    • Use the Active mode to see the values change in real-time acording to the audio input.
      • When active, you can adjust your system’s EQ acording to the suggested curves in real-time.
    • Use the Paused mode to “freeze” the values on-screen.
      • When paused, you can click on the boxes to bring that individual curve’s information to the front.
      • You can also "listen" in one location of a venue and bring the paused values back to your system’s location to adjust your system’s EQ values.
  • The slider to the right of the Diagnostic PEQ sets the maximum number of bands the Diagnostic PEQ will display. It will display up to the number of bands selected, picking the frequencies that need to be corrected the most.
  • Additionally, the Global Settings can be accessed through the settings button. This accesses the same settings as referenced earlier. One thing to point out is that the Block Size setting will affect the amount of information the Diagnostic PEQ can process. The larger the Block Size the more information the Diagnostic PEQ will display, the smaller the block size, the less the Diagnostic PEQ will display within the maximum number of bands allotted.
