Description
The RedVox Infrasound Recorder can capture sub-aural low frequency sound from volcanic eruptions, sonic booms, meteors, earthquakes, tsunamis, surf, and anything big that blows up.
Be part of the world-wide infrasound exploration!
Recording and streaming over wifi or cell starts as soon as you hit play.
The main display shows the infrasonic pressure recorded with the internal microphone and (if available) barometer. Microphones plugged in through the data port or audio jack will override the internal microphone.
Sound files are sent anonymously to the RedVox cloud server at redvox.io.
Your app version and RedVox device ID is shown in the lower center of the front page, and can be changed in Settings.
RedVox Recorder can record in the background to continuously monitor infrasound events and ambient noise. Although continued recording will consume more power, with the screen off it can run off the internal battery for many hours.
We can also save the location of the device so that we can correctly map the infrasound that your device is recording and perform source localization.
In the absence of cell or wifi, Recorder will save to memory and retransmit when communications are restored if the backfill setting is on. A record of the communication dB level is saved when available.
You have access to all the files recorded in your device in a directory you choose during installation.
Continued use of GPS running in the background can decrease battery life.
PRIVACY
-Access to the microphone is needed to run the app.
-The free level only supports 80 and 800 Hz audio.
-At 80 Hz, audio is heavily low-pass filtered below 32 Hz. There is no possibility of conversation or other identifiable human voicing being picked up.
-At 800 Hz audio is heavily low-pass filtered below 320 Hz - in the bass guitar frequency range, and well below the primary speech range of 1-3 kHz.
-Should you choose to use 8 kHz sampling or above at the Premium level, conversational audio could be recorded. The default privacy setting for the higher sample rates is private.
-The RedVox Device ID is either a truncated version of the scrambled vendor ID or user-specified in the settings. It is not traceable to any account or personal information.
