Connection Methods

Spike Recorder Connection Methods​

Choosing a connection method depends on your SpikerBox and the device running Spike Recorder.

USB Connection​

Use USB when both your device and platform support a USB connection.

USB is usually the preferred connection method for newer Backyard Brains devices because Spike Recorder can recognize the device directly.

Open the Spike Recorder app, plug in the USB cable, and turn on the SpikerBox.

When connected by USB, Spike Recorder displays a USB/device button near the top-left area of the interface. A highlighted outline around the button indicates that the device is connected.

Blue “Laptop” Cable​

Use the blue cable for computers with separate headphone and microphone ports.

Plug the signal into the microphone input, not the headphone output.

Note: A generic audio cable will not work. The blue cable routes the SpikerBox signal into the computer’s microphone input.

After plugging in the blue cable, select the correct audio input in Spike Recorder:

  1. Open the Config menu by clicking the small gear icon in the top-left corner.
  2. Look below the filtering options.
  3. You should see a list of available audio input devices.

Each input device has a dropdown menu on the left side. This menu controls two things for that input channel: the graph color and whether the channel is active.

Select a visible color, such as green, for the external audio input connected to the SpikerBox.

Select black for any input channels you want Spike Recorder to ignore, such as the computer’s built-in microphone or webcam microphone.

Green “Smartphone” Cable​

The green “smartphone” cable is no longer supported and no longer ships with any SpikerBox. Please connect by USB instead.

Connecting to Other Software​

If you are using the blue cable to connect your SpikerBox, you can use any program that records audio, such as Audacity.

Keep in mind that the Plant SpikerBox, Heart and Brain SpikerBox use amplitude modulation (AM) with a 5 kHz carrier signal. Spike Recorder automatically removes this carrier signal.

If you are connecting via USB, you can also load the data directly into your own program. Here are a few resources for setting up your own host software:
