To ensure that the audition is performed by the actual participant, an introduction must be made at the beginning of the video.

The introduction must be clearly spoken into the camera.

The introduction can be spoken by the actual participant or by another person, in either case the face of the participant must be clearly visible.

If the introduction is made by another person, this person may not be visible or audible during the rest of the recording.

For better sound quality, it is recommended that you adjust the microphone sensitivity manually. The automatic microphone control often makes a piano sound louder and a forte softer than actually played. This results in unwanted "dynamic jumps".
