Performance - Audio - RMAA
RMAA is a package of tools for evaluating the analog and digital channels of any audio device, whether it is a sound card, an MP3 player, a consumer CD/DVD player, or an acoustic set. The results are acquired by employing frequency analysis techniques to play and record test signals flowing across the examined audio route. Additionally, a more recognizable mark is supplied for individuals who are unfamiliar with measured technical parameters—a new version is the result of two years of development by the industry's leading experts in digital audio. RMAA 6.0 increases the bar for spectrum analyzer comfort and usefulness. It is the preferred program for fans, pros, and audio journals worldwide; some manufacturers are designing new devices with RMAA testing as an essential part of the development process. In short, the program is currently a de-facto standard for measuring technical parameters quickly and easily without the need to invest tens of thousands of dollars in specialist measurement instruments. The following are the RMAA results:
