Laptop: Erika AI Application (Video+Audio Enhancing) —>
Laptop: Online Event/Streaming Application (Zoom, OBS, etc) : with “Erika Virtual Camera” selected as Video Source and “Erika Wireless Microphone” selected as Audio  Source.

Erika Wireless Microphone

Erika is a small, wearable, cable-free Microphone. It is intended for use as an audio source for Online activities such as Online meetings or Live Streaming events. The  Microphone communicates wirelessly with a matching Receiver attached to a computer via USB. The Erika Microphone provides audio in a convenient and mobile fashion for the Online user.

Operation of the Erika Microphone
To use Erika Mic, first, plug the white Erika Receiver into your computer’s USB port via the supplied cable. To improve wireless reception, it is recommended that the Erika  Receiver be elevated from the table. Use the carrying case to elevate the Receiver by inverting the carrying case (without the lid) and running the USB cable up through the carrying case, with the Receiver plugged in on top.
Position a Microphone sideways up on a tabletop, or wear the Microphone in the vertical position. If the Microphone has sufficient battery power, it will automatically connect to the Receiver.
When the Erika Mic is connected, the Receiver’s LED will be solid Green. The Receiver’s LED will be solid Red when all Erika Mic(s) are powered off, out of range, or unpaired with the Receiver.
To charge the battery of an Erika Mic, attach to a USB power source. Erika Mic’s LED flashes Blue when charging and solid Blue when fully charged. It will take less than 3  hours to complete a full charge. The Erika AI Application provides a battery life indicator for each connected Microphone.
If Erika Microphone is plugged into a USB power source, it will be muted and powered down, and as it is charging, the Blue LED will flash. When fully charged, the Blue LED  will be on solid. Note that the Erika Mic cannot be over-charged or over-discharged. Thus, you can leave the Erika Mic on a USB power source, such as a computer or AC-powered USB Power Supply. Most USB battery banks will not charge Erika due to the low charge current.
A slowly flashing yellow LED on the Erika Mic indicates that the battery is low, with less than two hours remaining.
The Erika Receiver does not need to be charged – it is only operational when it is plugged into the computer via USB.
How to Place or Wear the Erika Mic
Erika Microphones can be positioned on a tabletop in front of a participant or worn.
If placed on a tabletop, secure the provided magnet near the edge of the table in front of the speaker. Set the Microphone on the magnet. If the Microphone is in the sideways up position, it is ready to use and will connect to the Receiver. If the Microphone is in the face-down or face-up position, it is muted/disconnected from the system.  Participants should sit within a couple of feet of their designated Microphones.
When wearing Erika, keep the microphone in a vertical orientation with the mic port facing forward and the USB port pointing down, as this helps prevent rain from entering the USB port.

Erika is typically worn in the center of the chest, over the sternum 4 to 5 inches down from the wearer’s chin. If you have an implanted medical device, observe all recommendations concerning these devices. For example, since the Erika Mic has an embedded magnet and a backing magnet, keep the magnets at least 6 inches from your implanted devices.

After using Erika, you may set the Erika Mic face-up or face-down. This will place Erika into the lowest power state. Or you may disconnect the Erika Receiver from the USB port. Either way, the Erika Mic will power off. When appropriate, you may use the supplied cable to recharge Erika Mic.
You may hide Erika behind a lapel, in a pocket, under clothing, or covered with a piece of matching fabric, with minimal effect on audio quality.
*** Note that using Erika Mic on a table top instead of wearing the Mic has the distinct advantage of preventing participants from walking out of the room and still wearing an active Mic. The table top magnets also serve as placeholders which allow participants to align themselves more easily within their particular Extraction Window of the Erika AI Application (for a close-up view of the participant).

Dynamic Audio Switching
When more than one Erika microphone is connected to an Erika receiver, dynamic audio switching is employed to select the appropriate source microphone. Only 1 speaker at  a time is allowed to send audio into the system – the current speaker. If more than 1 person is speaking in a given moment, the system makes it’s the best guess of who is the current speaker and only allows that person’s audio through.
Dynamic audio switching works optimally when each user is at least 3 feet apart. Close proximity reduces the effectiveness of dynamic switching due to reverb and echoes. Loud background noises can affect operation.
Audio level adjustment
Each Erika microphone automatically adjusts the audio level gain as the user speaks. No manual gain adjustment is necessary. The gain for each microphone is adjusted independently so that loud and quiet speakers have approximately the same audio level.
Erika Wireless Transmission Information
Erika uses 2.4 GHz radio spectrum to communicate between the transmitter and Receiver. Erika utilizes random frequency hopping. This technique improves security and helps  Erika to coexist with other 2.4 GHz devices. If interference does occur, Erika then avoids using frequencies with interference.
Using Erika with Various Programs
With Windows 11, most programs, such as Zoom, OBS, and Microsoft Teams, will immediately recognize and use Erika as your audio source. In some cases, you may have to choose “Erika Wireless Microphone” as your audio source within the given program.
WiFi
Erika coexists with WiFi and other 2.4 GHz devices.

In some cases, we will recommend taking the following steps:

  1. Switch from using 2.4 GHz to using 5 GHz WiFi. Switching has a side benefit as 5 GHz WiFi is much faster than 2.4 GHz WiFi. Your download and upload speeds should be faster with 5.0 GHz unless your service is the limiting factor. Note that the range of 5 GHz WiFi is shorter than 2.4 GHz WiFi
  2. Ensure that the Erika Receiver is not located close to a WiFi Router or Extender.
  3. Set your 2.4 GHz WiFi Bandwidth to 20 MHz versus 40 MHz.
  4. If you have multiple WIFI routers/access points, you need to assign them to the same WIFI channel. Otherwise, the RF spectrum may be consumed with WiFi traffic.

Receiver Positioning
A clear line-of-sight path from the Erika Mic to the Erika Receiver is ideal.
However, this is not always possible.

  1. If people are blocking the path, please elevate the Receiver above the height of the people. You may use a USB 2.0 Extension Cable to do so.
  2. Other obstructions may interfere with transmission. Attempt to locate the Receiver in such a location that the obstructions are avoided.
  3. If you are using multiple Erikas, keep each Erika Mic at least one meter from each other. Keep every Receiver at least 1 meter from each other. You will need longer USB-C  to USB-A cables, which are widely available from many sources. Or you may use USB 2.0 Male to Female Extension cables. Always use a Receiver Stand or some other method to elevate the Erika Receiver off the table. You can use the carrying case as a Receiver stand by inverting the case (without the lid), running the USB cable up  through the case, and attaching the Receiver in the elevated position.

How do I survey my location for Wi-Fi 2.4GHz to check for heavily used channels?
A WiFi Analyzer is used to survey a location’s WiFi channel usage. One example is the FREE Net Spot application, available here (https://www.netspotapp.com /wlan-wifi-analyzer.html). Net Spot has a beautiful, easy-to-use interface and is suitable for both beginners and experienced network administrators.
The Net Spot app runs on Windows, Mac, Android, and iOS, providing you with a visual representation of what WiFi channels are in use, and each signal’s relative strength. The more sources that send a WiFi signal out over a single channel, the less desirable it is for us because the other signals will cause interference with Erika. Erika will automatically block out channels with heavy interference. It is preferred to have as many channels available for Erika.
Another option to provide more channels for Erika is to move your local WiFi network up to the 5GHz band, turning off the 2.4GHz transmission. The Net Spot application does operate on the 5GHz channels as well, so you can see how populated those channels are.
Some other WiFi analyzers are available (found through an Internet search, Apple App, or Google Play stores)
