Example Test: Sound quality

Please rate the sound quality compared to the reference

Rate the sound quality of the test sounds by comparing them with the reference sound.

Sound quality relates to the amount of artefacts or distortions that you can perceive.

These can be heard as tone-like additions, abrupt changes in loudness, or missing parts of the audio.

• Click the Reference button to play the reference sound.
• Click the Stop button to stop playback. This will also reset the audio to the start.
• Use the slider buttons to listen to the different test sounds.
• You can then rate the quality of each sound by dragging the slider button along the track.
• Click the Sort button to sort the sliders by rating.
