The essence of RightMark 3DSound is the creation of an independent synthetic audio test for estimating hardware and software capabilities of DirectSound-compatible devices.

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.

CPU Pentium or higher, operating system Microsoft Windows 98 or higher. In W2K the program may run unstable (the possible cause is in WDM-drivers for sound cards, which are often released as betas and can contain bugs).

The test includes:

• RightMark 3DSound: Positioning Accuracy test
  Tests audio source positioning quality in DirectSound3D. Requires subjective listening to a 3D audio scene with a user-controlled moving sound source. Supports all key features of EAX4 Advanced HD.
• RightMark 3DSound: CPU Utilization test
  Measures CPU load depending on DirectSound device mode. Synthetically emulates main cycle of a typical ingame sound engine. Besides standard DirectSound diagnostics checks for supported EAX version.
• RightMark 3DSound: Data Analyzer
  We use statistical data processing to exclude influence of random OS activity bursts and also to get more information on CPU load. This provides us not only with average values (mean of distribution), but also with their dispersion (standard deviation).

We recommend using our programs under Windows XP with Service Pack 2 installed. Operation stability also depends on soundcard drivers.
