Sound analysis & recording issues#

1. No sound recordings appear in the morning#

If your noise graph shows data but no individual audio clips were saved, check the following:

  • Volume Threshold: The app only records sounds louder than your threshold. Go to Settings ➔ Sleep noise analysis ➔ Recording volume threshold and lower it (e.g., to 15% or 20%).
  • Microphone Conflict: Android allows only one app to access the microphone. Close all other apps (voice assistants, white noise generators) before tracking.
  • Missing Permissions (Android 11+): Ensure you have granted the Display over other apps permission so the app can initialize the microphone in the background.

2. Too many short or constant recordings (e.g., fan noise)#

  • Reason: The volume threshold is too low.
  • 👉 Fix: Increase the threshold to 25%-35% under Settings ➔ Sleep noise analysis ➔ Recording volume threshold.

3. Weird chirping or sonar noise in recordings#

If you hear feedback or high-pitched artifacts:

  • Disable Audio Enhancements: Turn off Dolby Atmos, Adaptive Sound, or Equalizers in your phone’s settings.
  • Change Input Mode: Set Input to UNPROCESSED in Settings ➔ Sleep noise analysis ➔ Input.
  • Phone Placement: Ensure the bottom speaker/mic area of your phone isn’t touching the hard surface directly.

4. The graph shows a sound was detected, but there is no audio recording#

If you see a sound icon but cannot play the clip:

  • Lower Volume Threshold: Lower the percentage in settings to ensure the recorder triggers.
  • Reset Storage Path: Go to Settings ➔ Sleep noise analysis ➔ Storage path and tap RESET.

5. How do I listen to sound clips marked on my graph?#

  1. Look for the mic Microphone icon along the graph timeline.
  2. Drag your finger across the graph to highlight the specific time period.
  3. Tap the Play icon in the top right corner.

6. A sound was tagged incorrectly#

  • 👉 Fix: You can manually edit or remove tags in the app’s audio player.
  • Help us improve: When you change a tag, the app may ask if you’d like to share the clip with our team (support@urbandroid.org) to help us retrain our AI.
