Welcome

Thank you for taking part in this experiment!

Your task is to pick 1 out of 6 test sounds that is most similar to a recording of singing-voices (the reference). The test sounds are taken from different source separation methods that try to extract singing-voices from a song. The best source separation method should produce a test sound that is perceptually identical to the original recording.

Examples of things that might influence your decision:

• Portions of the original recording missing
• Artefacts, such as noise
• Changes to the timbre of the singing-voice
• The presence of other instruments that are absent in the reference, e.g. guitars, drums
