Listening test: Transposition of singing voice

ATTENTION: Due to technical constraints this test will not run with Safari. Please use either Chrome or Firefox!

Thank you for your time! This is a perceptive test to evaluate the quality of our new pitch transformation algorithm. You will hear short samples of singing voice, real and synthetic, and you will be asked to rate the audio quality on a scale between 0 and 100. This will be used to create a mean opinion score of each of the transformation algorithms.

We are asking for your subjective impression, there is no right or wrong. However, the differences may be very subtle so please listen very carefully and don't be shy to listen to the recordings multiple times if you are unsure. The whole test should take about 10 minutes.

Instructions

Make sure you have the time to take the test in one sitting. It will take around 10 minutes.
Do the test in a quiet place.
Use headphones.
Verify that the sound level is loud enough to hear the sound details properly. Use this testsound to adjust your volume now.
If there is any technical problem (e.g. sound not playing), tick the box in the row "Problem". (please note that it may take a few seconds for all sounds to load)

Listen to a file once then rate the audio quality on a scale from 0 to 100 corresponding to the following labels:

Rating	Label
81-100	Excellent
61-80	Good
41-60	Fair
21-40	Poor
0-20	Bad
-1	No rating

If you are unsure, you can listen to the samples as much as you like but try not to spend more than a minute for each sample. (You can always go back in case you change your mind.)
