Examples of recent updates (April 2019):
v8.0 New feature: load one or two stored spectrum files and view them together with real-time data.
New v8.1 generator option: Phase switching for right stereo signal
v8.2 The new menu option “Adjust Resolution” allows you to configure sample lengths of 4096, 8192 or 16384
The new 1/12 octave RTA mode version 8.4.2
Unique 1/3 Octave ISO Calibration – You can correct the response of your phone’s microphone. The octave calibration discs are moved up or down for a flat response and to match the overall SPL with the external meter. Save/restore Cal files (also compatible with popular Dayton Audio iMM-6 and MicW i436).
Use metrics for concerts, home theater, acoustics, car, etc.
AudioTool FFTs sets of microphone samples. Hann tires reduce smoothing. SPL is calculated in real-time. Spectra can be saved, then loaded, and viewed with the spectrum live. The “Store” button stores the current direct spectrum – “Download” displays a list of stored spectra for identification.
To hide the buttons, touch the screen. To retrieve it, click again. To zoom in, tap the screen. To move the scale, drag it up or down (left or right).
A couple of indicators can be displayed: each can be moved to any position and will show the SPL and time/frequency values there. The indicators can be turned on and off in the menu.
An amplifier polarity checker can be used to verify if the amplifier is wired in phase: connect the AudioTool output to the speaker under test, select “Polarity” on the signal generator screen, then return to the RTA screen. If the amplifier is out of phase (reverse polarity), AudioTool will display “Pol -” otherwise, “Pol +++” if the amplifier is in phase.
The Noise Parameters function displays a set of overlapping NC profiles on the 1/1 octave RTA display and also displays the current calculated NC value in real-time.
The chart recorder displays a moving trail of sound pressure level measurements over the past few minutes.
RT60 measurements (the amount of reverb or echo present in the room or hallway) can be made using the “RT60” function, which is activated with a loud clap (or similar) with or with Pink Noise from the AudioTool generator.
The signal generator generates white and pink noise, sine waves, square waves, triangular waves, sloping, linear sine waves, and record sweeps, chirps, and pulses. The generator uses multiple periodic buffers and is updated randomly to ensure truly random white and pink noise.
The frequency accuracy of the signal generator is usually around 1%. The precision of the sine wave is good over most of the sound range. The front and back edges of the other signals will show a decreasing timbre and frequency response in the higher ranges, depending on the mobile phone used.
