Description

The RedVox Infrasound Recorder captures audio and sub-aural low frequency sound from volcanic eruptions, sonic booms, meteors, earthquakes, tsunamis, surf, and anything big that blows up.

Now you can also collect acceleration, magnetic field, and gyroscope data.

Be part of the world-wide exploration of sound and vibration!

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, accelerometer, magnetometer, and gyroscope. 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.

You have access to all the files recorded in your device. Under Settings, Files, the Copy to Documents function will make these files available through iTunes. Please refer to the API900 Python SDK at https://pypi.org/project/redvox/

Continued use of GPS running in the background can decrease battery life.

PRIVACY
At 80 Hz, audio is low-pass filtered in the device to remove any possibility of conversation or other identifiable human voicing being picked up. At 800 Hz sampling, you are within the bass guitar frequency range. Normal speech sampled at 800 Hz is considered unintelligible.

V2.2 and above has additional privacy settings for accounts with a verified user name and password. These privacy setting are recommended for sound capture above 800 Hz sample rates.

Location can be disabled either at the Device Settings or within the Recorder Settings. In the Recorder Setting you can specify a fixed location (see EXPERT LEVEL).
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.

EXPERT LEVEL
Array processing requires precise timing synchronization, accurate sensor locations, and specialized software. Please contact us for more details.

Great app for data capture

This is a really nice app for recording sensor data on your phone. I used it for a class exercise to audio and accelerometer data on multiple phones. In addition to a nice website where you can analyze data, There are excellent python utilities to extract the data off the server and to aid in analyzing it.

Another “crowdsourced” app. You are the product!!

No way to make data private. Requires public upload. Uninstalled.

“For example, you may elect to use the Service to record and allow us to process audio files. You may also use the Service to provide other users technical information about your recordings including how and where the information was collected. By engaging in some of these uses, you will distribute information publicly. That public information may be viewed and collected by others. As a result, when using such features only share what you wish to make public.”

Designed for research, limited usefulness

You can see the infrasound graphically while running. To access more graphs, need to register & login through redvox.io

Developer Response ,

It is true the scientific integrity of the data is our top priority, we've expanded the available sensor fields and are exploring their use and presentation. Thank you for your patience and interest, we hope to build friendlier interfaces in the coming year.
