Measuring and Adjusting Local Latency in doozzoo

With this tool, you can measure the internal latency of your local audio hardware (roundtrip) and compensate for it.
This ensures:

• You can play your instrument in sync with the doozzoo metronome or audio player.

• The other side hears your playing perfectly aligned with the backing track.

• Your recordings with the doozzoo APP Recorder remain synchronized.

You can set the local latency compensation in two places:

1. In the Settings on the dashboard.

2. During a running session via the Latency App.
   
   

1. Adjusting Local Latency Compensation in the Settings

Step-by-Step Instructions

1. Use Headphones

• Always wear headphones to avoid echoes.

• Make sure the headphone volume is not too low.

2. Log In to Your doozzoo Account

• Access the doozzoo dashboard with your credentials.

3. Navigate to Settings

• Open Settings and select Headphone Mode.

4. Recalculate Local Latency Compensation

• Go to the Local Latency Compensation section.

• Click Recalculate here.

5. Perform the Test

• Hold the headphone cup directly against your active microphone.

• Keep it steady—avoid wobbling to reduce unwanted noise.

• This works with both built-in and external microphones.

• Start the test and wait until you hear the final click. The test completes automatically.

6. Save the Latency Value

• Click Confirm to save the calculated latency.

2. Adjusting Local Latency Compensation in a Running Session

Step-by-Step Instructions

1. Access the Latency Tool

• During an active session, open the APP (A).

• (See screenshot below for details).

2. Manual or Automatic Adjustment

• Adjust the latency manually by changing the numerical value (B).

• Or measure it automatically by selecting the appropriate option (C).

3. Mute Microphones During the Test

• Ensure all microphones are muted during the test.

• This prevents background noise from the other side from interfering with the measurement.

✨ With these settings, your instrument will always stay perfectly in sync—whether you’re playing live with the metronome, performing for your students, or recording sessions with the APP Recorder.
