Impulso Lite allows you to measure the acoustic response of your room using your iPhone. You can visualize the measured reverberation time (RT) in octave bands and then simulate how the acoustic response of your room will be improved when adding artnovion acoustic products. You can enter room dimensions and select the type of room you are designing for. The app will then tell if your room meets the expected RT and you can select products to optimize the response accordingly. Impulso Lite allows you to take a measurement with an internally generated signal if you are able to play it via a loudspeaker system, or using an external impulse source, such as a balloon, if you don’t. Compatible with built-in or external microphones. Check out Impulso Pro for detailed plots of energy time curves, to check for undesirable reflections, a frequency plot, which you can zoom in and a table with the acoustic parameters of your measurements such as C80, D50, STI and Bass Ratio. Impulso Pro also adds tramlines to the RT plot so you can fully optimize the response to meet the criteria for the room type selected. You can also display the spectral response of the microphone input using the new Real Time Analyzer. Check more at

    Doesn't work guidance is horrible
    All it does is measure ambient room noise. There is no testing and no guidance. How could they possibly release this to the public. This is disgraceful

    Not functional!
    I have tried this app with 2 different iphones and an ipad. I cannot get the sound output to speakers that are connected via bluetooth, airplay or cable. It simply doesn’t work. There must be an issue in the app that doesn’t allow the sine sweep to be output to anything than the device speaker itself. Please fix this. Show more

    Partially doesn’t work
    This apps is designed really well, but on an iPhone X, it doesn’t recognize a 3.5mm input, so I’m unable to test the acoustics in my room with my studio monitors. I was using the app to get a good sense of how the pro version would work, but the free version needs to at least work with an output source to be anywhere near accurate. It also wasn’t compatible with my Focusrite 2i2 plugged in via USB, which means I couldn’t use my microphone as a source to measure room sound. Please fix this app, it’s the best looking and easiest to use on the App Store. I will correct my review and purchase the pro version when that happens. Show more

    The app locked up every time it is used
    I have redownloaded the app and once you run the sound test it just sits on the same screen with no indication of anything. Please fix thanks
