Q: I can't hear the student in sync with the audio player, metronome, or piano.

Please make sure the "Student" mode is enabled. If the issue persists, ask your student to recalibrate their microphone by following the video guide. This should allow you to hear the student in sync with the player, metronome, or piano. Important: Unfortunately, real-time accompaniment using the virtual piano is not possible due to internet latency. Instead, use audio files with vocal/music exercises. You can upload them to the player and hear the student in sync with the audio file.

Question 1

My video quality is low

Accepted Answer

This behavior is usually related to the automatic adjustment of video quality to match the current internet speed, ensuring connection stability.

Solution:

Enable stable quality:

In the lesson interface, locate the video quality settings button (found near the camera icon).
Choose a setting:

Select the "Auto-reduce video quality" option in the menu that opens.
Or, manually set a fixed video quality that your camera supports.
"Auto-reduce video quality" allows the app to smoothly adjust quality, minimizing jitter.
A fixed setting stabilizes the picture if your internet connection allows it.

Additional recommendation:

For better stability, ensure your internet speed meets the recommended values (check on speedtest.net: speed not lower than 25 Mbps, ping up to 100 ms). Use a wired connection instead of Wi-Fi whenever possible.

Question 2

The virtual piano volume is too low.

Accepted Answer

If the audio track from the virtual piano is not loud enough, please check the volume settings within the MOOZ app.

Solution:

During a lesson, locate the virtual piano panel.
Below the virtual piano controls, you will see a volume bar.
Move the slider to the right to increase the virtual piano volume to a comfortable level.

Important: This setting adjusts the volume of the virtual piano only on your side, the student also needs to adjust the volume on their side.

If the audio track volume is set to maximum but the sound is still quiet, also check the overall volume of your computer's speakers or headphones.
