Thank you for your time!
This is a perceptive test
to evaluate the quality
of our new intensity transformation algorithm.
Instructions
Make sure you have the time to take the test in one sitting.
It will take around 5 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 test sound 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)
You will hear pairs of short samples of speech.
For each pair please rate which one you think was sung louder
/ with a stronger voice.
For your response,
please take into account only the timbre of the sound
not the volume.
If you think the left sound was sung in a louder voice
please select a number on the left according to the degree
of the difference.
If you think the right sound was sung in a louder voice
please select a number on the right accordingly.
Take your time and listen carefully.
Sometimes the differences are very subtle.
If you are unsure, you can listen to the samples as much as you like.
