Download the software for Windows (PC) from the Downloads section of the DM-RTA product page here. After downloading, the DM-RTASmartAppPC Zip folder should be in your Downloads folder. Double click the Zip folder to open, and then double click on the DM-RTASmartAppPC application file to start the installation process.
TrueRTA is a free audio analyzer software for Windows. Using this software, you can easily check out audio input and output devices connected to your system. If you have connected a microphone, then you can start speaking through it and corresponding signal fluctuation will be shown on the display.

Populated with every connector we could think of, and coupled with the new DM-RTA app, AudioControl’s DM-RTA helps you take your car audio, marine audio or home theater installations to new levels of perfection and control. A real-time analyzer (RTA) is a professional audio device that measures and displays the frequency spectrum of an audio signal; a spectrum analyzer that works in real time.An RTA can range from a small PDA-sized device to a rack-mounted hardware unit to software running on a laptop.It works by measuring and displaying sound input, often from an integrated microphone.

A real-time analyzer (RTA) is a professional audio device that measures and displays the frequency spectrum of an audio signal; a spectrum analyzer that works in real time. An RTA can range from a small PDA-sized device to a rack-mounted hardware unit to software running on a laptop. It works by measuring and displaying sound input, often from an integrated microphone or with a signal from a PA system. Basic RTAs show three measurements per octave at 3 or 6 dB increments; sophisticated software solutions can show 24 or more measurements per octave as well as 0.1 dB resolution.

Types[edit]

There are generally two types of RTAs:

RTAs employing analog signal processing, and
RTAs employing digital signal processing (DSP).

The main difference between the two types is that the analog RTAs use a series of hardwired, analog bandpass filters to break the signal into frequency bands prior to measuring it. Digital RTAs use digital sampling technology and microprocessor based digital signal processing to perform necessary calculations, such as fast Fourier transforms, to perform the measurements and thus do not need analog hardware filters to isolate each frequency band. The digital approach to signal analysis generally yields much higher accuracy and resolution and thus most RTAs currently in production use digital signal processing technology.^[1] Digital signal processing is more cost effective.

Professional use[edit]

RTAs are often used by sound engineers and by acousticians installing audio systems in all kinds of listening spaces: Venues, home theatres, cars etc. The parameters that can be measured are the spectral aspects of sound reproduction caused by effects like resonances and constructive and destructive interference, but not imaging and spatial aspects. In professional audio many systems incorporate an RTA along with a device that also performs equalization. While measuring pink noise or other test tones, such a controller can level out the frequency response by employing a set of adjustments in the appropriate frequency areas according to the system's interaction with the venue's size, shape and construction materials, among other things.
