Instructions:

• Most important: use high quality studio headphones and a good soundcard!
• Listen through all test files and test sets before you do any ratings to get used to the material.
• Rate the quality of the test items only compared to the reference on top.
• Try to rate the overall impression of a test item and don't concentrate on single aspects.
