Measures woofers, midrange, and tweeter drivers.
Test signal is built-in, outputs from the device, or download the signal from our website.
Available as an in-app purchase in AudioTools for $3.99.
Delay Finder -- Measure time delay from a speaker. Sends an signal to a driver, then measures the time it takes for that signal to return. Shows ms and distance.
You can enter the air temperature, and use either feet / Fahrenheit or meters / centigrade units.
Included in the base AudioTools app.
Speaker Distortion -- Measure distortion of a speaker, using the built-in or the iAudioInterface microphone. See our new demo video of this module.
Use this to compare drivers in a control room or rental environment, to find signs of early deterioration or abuse, before they become audible.
Available as an in-app purchase in AudioTools for $5.99.
Impedance Meter -- Measure impedance, from 0.5 ohms to 5000 ohms +/-1% or 1 Ohm. Also computes power requirements in watts for a given voltage speaker system. Results are shown numerically, or may be plotted. Requires iAudioInterface 1 or 2.
See our new demo video.
Available as an in-app purchase in AudioTools for $24.99, also includes Impedance Plot (below).
Impedance Plot -- Sweep the generator, and graph speaker impedance to see driver resonance and impedance as a function of frequency.
Both impedance modules are included in the in-app purchase price. Includes support for the optional Reference Curves feature.
Available as an in-app purchase in AudioTools for $24.99, also includes Impedance Meter (above).
STIPA Basic -- Speech intelligibility module that meets all of the requirements of the international STIPA standard, and as such may be used for NFPA Fire Code work.
Provides the correct STIPA value, using the same algorithm as our STIPA Pro module.
Available as an in-app purchase in AudioTools for $49.99. Can be used towards purchase of STIPA Pro.
STIPA Pro -- Speech intelligibility module. Industry-standard test for speech intelligibility, based on v4 of the international standard. Complies with all current fire and building codes.
Includes advanced features, including averaging of multiple tests, save / recall of results, and the ability to email detailed results, or transfer them to your computer for reporting.
Play the test signal from the iOS device, or download it from our website and play it from a CD or WAV file player. Average up to 6 measurements.
Available as an in-app purchase in AudioTools for $199.99, or $149.99 if you already have purchased STIPA Basic.
