This mail has been sent to several mailing lists, apologies if you receive this mail multiple times! Dear all, We are conducting an online listening test evaluating a classification system for audio effects based on perceptual attributes. In the test you will hear several short musical examples, before and after application of an audio effect. You are asked to choose a main perceptual attribute that has changed due to the sound transformation, and optionally secondary attributes. The test consists of audio examples each 5-10 seconds long. The decisions should be made spontaneously, so the test should not take too long (ca. 30 min.). Your participation would be highly appreciated. You can find the test at: Thank you very much in advance, Thomas Wilmering Centre for Digital Music (C4DM) Queen Mary University of London |
