Bob Schulein and Dan Mapes-Riordan, audio-industry consultants and co-founders of ImmersAV Technology, discuss their new audio files that test the limits of a listener's ability to perceive the dynamic range and high frequencies in high-res audio (HRA) content, including their motivation for developing the tests, how the tests were created and validated, judgement techniques, comments about each test, results from testing among AES members, what you need to conduct the tests for yourself, answers to chat-room questions, and more.

Note: The test files are now posted and ready for anyone to download them here .
