Then tap done and place the microphone as close as you can to the transducer you wish to judge. Tap the wrench icon and in the ETC Graph setup screen you will see a Latency box. NOTE: This applies to Internal Trigger mode only.Įxternal trigger mode does not support delay measurements. The first step you need to perform is to take a reference measure to determine the latency of your system. Plot will still show the room decay, minus the initial arrival time of the Mode waits for an incoming signal, it cannot determine absolute time ofĪrrival, and therefore the speaker time delay cannot be computed. LARSA will wait until it detects a signal at the trigger level on the setup

Next, download the signal, eitherįrom our website on the Downloads page, or by using the Surround Generator on On the Setup page, select “External Chirp”.

In this case,Īfter downloading and installing Surround Generator on your Apple TV 4k, youĬan select the Atmos signals, and then choose LARSA as the signal type for any TV 4k app, “Surround Generator” as the source for the signal. You can use LARSA for example with a surround sound system, by using our Apple That you do not need any connection from the iOS device to the sound system, so This allows you to use another sound source, rather than the iOSĭevice that is running LARSA, to generate the chirp signal. With our iTestMic, the configuration will be the same, except you will use the line output of your iOS device to feed the measurement signal into your system.įinally, you can use the internal microphone to capture the measurement signal, although for best results, a measurement microphone should be used.Īvailable. You will plug in your measurement microphone into the microphone input of the interface and set up the microphone in the location where you wish to measure the response. With our iAudioInterface2, you will plug in the line output of the interface into the input of the speaker you want to test. There are a number of ways to record this signal.
