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.
