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.

Leider kann das Messsignal jedoch nicht auf die Lautsprecher gelegt werden. Durch das Klatschen ermittel ich bei jeder Messung unterschiedliche Werte ### 5/5 — Top! *2023-10-21, version 6.0.1* Perfekt! ### 1/5 — Doesn't work guidance is horrible *2022-03-06, version 5.1* 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 ### 1/5 — Not functional! *2021-11-08, version 5.1* 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. ### 1/5 — Unbrauchbar- stürzt immer ab *2021-06-09, version 5* Leider komplett ohne Funktion, da es jedes mal bereits vor dem Messen abstürzt! ### 1/5 — Dose not work *2021-05-25, version 5* Constantly crashes, I think the app is out of date with recent updates to iPhones ### 1/5 — The app keeps crashing ! *2021-03-02, version 5* Can’t get it to do the one thing it’s supposed to do ### 1/5 — No worky *2020-12-27* Didn’t work with iPad ### 1/5 — Crashes *2020-09-29, version 5* App crashes frequently. ### 1/5 — Crashes all the time on iphone xr newest patch level. Useless. *2020-06-15, version 5* Crashes all the time on iphone xr newest patch level. Useless ## Frequently asked questions about Impulso ### What is Impulso used for?
