When this happens, turn off any microphone attached and switch to signal from the board.
If you like to know if there is an internal microphone, open Spike Recorder and for an example clap your hands and if it's displayed on Spike Recorder then that means you have an internal microphone!
Some laptop chargers can add a lot of noise to the recording when you are doing experiments, so to significantly attenuate that noise check-mark the 50 or 60Hz mains frequency, depending from your country's mains frequency, like shown in the pic below.
Remove your charger from the wall and from your notebook, avoid Smartphone or any charger connected to a nearby wall, those are little noise makers! Sometimes White tube lamps can add noise too, try a different spot.
Last but not least, make sure that you have our latest version of our BYB SpikeRecorder downloaded. After you've turned it on, connect your board to your laptop. Go to config. icon and see if there is anything listed under "select port" ? If there is, please try to connect to it.
