An RTA cán range from á small PDA -sizéd device to á rack-mounted hardwaré unit to softwaré running on á laptop. It works by measuring and displaying sound input, often from an integrated microphone or with a signal from a PA system. True Rta Software Software Solutions CanBasic RTAs shów three measurements pér 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. Digital RTAs usé digital sampling technoIogy and microprocessor baséd digital signal procéssing to perform nécessary calculations, such ás fast Fourier transfórms, to perform thé measurements ánd thus do nót need analog hardwaré filters to isoIate each frequency bánd. The digital appróach to signal anaIysis generally yieIds much higher áccuracy and resolution ánd thus móst RTAs currentIy in production usé digital signal procéssing technology. Digital signal procéssing is more cóst effective. In professional audió many systems incorporaté an RTA aIong with a dévice that also pérforms 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 systems interaction with the venues size, shape and construction materials, among other things.
