RightMark Audio Analyzer stelt je in staat om verschillende metingen uit te voeren van de geluidskaart. Het programma plot vervolgens de verkregen waarden in een grafiek. De nieuwste versie van RMAA is genummerd als 5.4 en kan via deze directe link gedownload worden. Op de site vinden we de volgende veranderingen:
A new test of intermodulation distortion has been added. From RMAA 5.1 the common IMD test uses a standard SMPTE test signal. In a new Swept sine IMD test, we use a set of 2 harmonics with a frequency difference of 1 kHz (CCIF standard), sweeping the whole audible range of frequencies. Thus, the dependence of intermodulation from frequency is tested. This test allows detecting high-frequency intermodulations that are specific to internal sample rate convertion (SRC) algorithms of a sound card. An auto-normalize function has been added for more accurate measurements when exact matching of I/O levels is impossible. Also this feature addresses the problem of cheated measurements with lowered input levels set for reporting low noise levels. In acoustics testing mode, we have added: separate measurement of 2-nd and 3-rd harmonics; normalization of distortion level to the input signal level; a new THD-vs-frequency test using a set of fading-in harmonics with different frequencies. The graph anti-aliasing has been improved.[break]
