Soundcheck

Test the sensitivity of your device's microphone.

This app will let you either:
- self test by playing a sound through the speakers and recording it after
- test with a sound from an external speaker to compare against other devices.

Once the soundcheck is complete, you can upload the recording to see how sensitive your device is.
The outcome will be visualised on a spectrogram.

*This app is available as part of the New Forest Cicada Project and, although it can be used otherwise, there is no guarantee that it may do what intended outside of the scope of the project.
