Sleep noise recording

TIP: Are you making noises in the night? Sleep as Android will tell you!

What is noise recording good for?

Noise recording allows you to record significant noises during your sleep. You may reveal that you are sleep talking, sleep laughing, snoring or even have a more serious issue (such as obstructive sleep apnea OSA).

Setup noise recording

Enable Settings > Sleep noise recording > Enabled
Set a Recording volume threshold. Usually the good value is around 10-20%, although this may vary with device.

How does noise recording work?

Noise recording is based on volume. Whenever a certain noise volume exceeds the configured threshold, noise recording is triggered and continues recording for a few seconds. If another noise over threshold event occurs, the recording is prolonged. Volume threshold is configured under Settings > Sleep noise recording.

You can check whether the phone is recording on the sleep tracking screen. The red light indicates that the phone is currently recording.


TIP: Seeing too many uninteresting recordings? Increase the threshold. Getting almost no recordings? Lower the threshold.

If you use lullabies, noise recording starts after the lullaby stops playing.

NOTE: In order to achieve good recordings we recommend keeping the phone close to your head with the microphone area not covered. We do strongly recommend using airplane mode during the whole period of sleep tracking.


Where to find noise records?

  • In the inv_ic_action_noise Noise tab, in chronological order from latest to last
  • In theGraphs tab under any sleep record in reverse order (tap a sleep record and then on Noise in the inv_ic_dots_horizontal menu)

Noise recording statistics

When you enable noise recording, the app also starts computing long-term noise statistics. This feature tracks the volume levels in your bedroom during sleeping. Bedroom noise is another factor which can influence the quality of sleep. You can see how much noise there was as a % under each sleep record.

Snoring detection

When listening to the noise recordings, you may find that some of those are tagged with #snore, while others aren’t. If you find the tags inaccurate, you can adjust them yourself, which will adjust the statistics accordingly. Length of the records with a #snore tag is added to snoring length.

Other sounds detection

Similarly to #snore, audio recordings may be also annotated with #talk, #sick, #baby, or #laugh, if our algorithm thinks that such sounds occur in the recording. Again, you can fix the tags manually if you find them inaccurate.

See our blog post for more details.

High quality recording

We recommend to keep high quality recording enabled (Settings > Sleep noise recording > High quality recording). This bring much clearer high sample rate recordings with minimum background noise.

NOTE: Features such as Snoring detection or Anti-snoring require high quality recording in order to function properly.
