what is the redvox infrasound recorder?
The RedVox Infrasound Recorder was an app initially designed to detect infrasound using your device’s microphone. Now, it not only records infrasound but it also utilizes the other sensors on your device such as pressure, acceleration, and more!
What is the best phone for using this app?
On Android, anything supporting Nougat and above should work. On iOS, it works best on the more recent phones.
How do i know if the app is recording?
You will know if the app is recording if waveforms are being plotted on the RedVox home screen or if the timer at the bottom is running.
what is a sampling rate?
The sampling rate is how many samples are being collected per second.
WHat sampling rate should i use?
The default sampling rate is 80Hz. We recommend recording at 800 Hz if you have the bandwidth.
will the app record my voice? how do I make sure the app isn't recording people's voices?
Speech recording can only happen at 8kHz sample rates. 8kHz can only be recorded after signing into your RedVox account. There is an option to make the data private, and there is a scrambling option to make speech unintelligible.
What does sync err mean?
SYNC ERR means that there is either no Wi-Fi or data and the files cannot be sent to the RedVox server. SYNC ERR is normally accompanied by a number which represents the number of files that are not sent to the RedVox server.
What is a data packet?
A data packet contains metadata about the device, app, timing information, and about the enabled sensor channels. Data packets also contain the raw data payloads for the enabled sensors. Data packets are created on the device, compressed, and stored for long term storage in the cloud.
What is the global device collection?
The Global Device Collection is a map of all locations we have ever received data from on one of our devices.
What is the data explorer?
The Data Explorer allows users to display the metadata and payload details of public data and data they have access to. Each row in the top half corresponds to an individual data packet received from a RedVox device. By clicking one of these rows, the details for that packet are displayed in the bottom half. Click in a row in the bottom half will display details about the particular sensor payload.
What is a redvox report?
A report provides analysis, plotting, and device status over a given time range with reference to a source event origin. Reports are generated for a user selected subset of RedVox sensors they have access to. Report products are user selected as well and include the following figure types:
- Microphone FFT
- Microphone Multires
- Barometer Waveform
- Barometer Multires
- Latitude Std
- Longitude Std
- Altitude Std
- Accuracy Std
What is a Group?
A group is a collection of devices and is generally defined by a bounding box of latitudes and longitudes.
I AM NEW TO PYTHON, ARE THERE ANY SPECIAL INSTRUCTIONS YOU COULD POINT ME TO?
The user manuals have step by step instructions on how to get Python and read the RDVX files. The user manuals have instructions for both Mac and PC computers.
