RightMark Audio Analyzer 5.4 has been released. The test suite performs various tests of electroacoustical performance of sound cards and other real-time audio devices. Testing is accomplished by playing the test signals and recording them after they pass through the testing chain. New features include:
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.
