About this app

IMPORTANT NOTE: firmware v0.0.64 and above is required for proper operation.

DM-RTA signal analyzer provides five of the most important tools that installers use to make systems sound perfect.

The DM-RTA can also generate the test tones and signals used for analysis, like sine waves, clicks, and pink noise.

This portable device features a built-in battery, which can keep its charge for about 3 to 5 hours, giving you plenty of time to take readings in a vehicle before needing a recharge. There's even 48-volt phantom power available for the microphones that need it to operate

* RTA, or real-time analyzer, visualizes system response across the entire sound spectrum. You can measure the acoustic response using a microphone, or the electrical response using the line inputs.
* Voltmeter displays a signal's voltage, so you can match a device's output to another's input sensitivity.
* Polarity Checker makes sure all your drivers are moving in the same direction at the same time.
* SPL Meter helps you level-match your speakers.
* Oscilloscope displays signals as sine-type waves that show a sound's frequency, voltage level, and whether or not it's clipping five-in-one signal analyzing tool voltage meter (Vrms).
* Real-time analyzer (RTA) 1/3, 1/6, or 1/12 octave resolution.

The DM-RTA app works with mobile device using a Bluetooth connection.

I am having a HUGE issue making the app recognize the Bluetooth connection to the phone. Using a Samsung 20S Ultra and have connection to DM-RTA, but no functionality works and no Bluetooth devices show in the app. Not very useful for an expensive add on.

You should go back to your developers and tell them to remove the GPS location requirement from your software. There is no legitimate reason legal or otherwise for you to be utilizing this data with audio tuning. It's a really good way to get sued for invasion of privacy, and lose customers.
