Scanner recording background noise

[Nate1n22]

I have my scanner streaming with RadioReference, and lets say I were to whistle or say something, it would eventually get played over the live audio at radio reference, but very quietly.
I have the cord running from the scanner to the laptop's mic port, so I don't see how it would be recording audio from the room.

Any ideas?

Is you scanner playing on the feed too? Also, can you hear your scanner in your room without the feed?

 

[Nate1n22]

No I have to have the feed going to hear my scanner, but I have a splitter so I could plug headphones or speakers into it to hear it.
Yes my scanner is playing the feed.

The only thing that I can think of is that you might have a microphone array. Does this sound familiar when you were setting the input device?

No, I am streaming with ScannerCast, and just signed into my RR account and started the broadcast

That could be the problem. Some computers have what they call a Microphone array in which it links multiple microphones together. Assuming your computer has a microphone (even if its the only one), you are also using a microphone port. Windows defaults to arrays and if you just plugged and played then Scannercast used the Windows default. I would go into Scannercast and check the input device settings. Let me know what one is selected and what you're options are.

Yeah, think I would setup on your line input for your scanner and make the changes in scannercast. Second make sure your computer doesn't have a mixer volume set on, if it is then move the slider down to 0.

The sound input is: Microphone (Realtek High Definition)
Control port: COM3 Speed: 115200

I not sure what other setting you may need, but those are the ones on the config tab

I have a Pro 433 scanner if that makes a difference

It could also be crappy wires.

If you have un insulated wires they can easily transmit any vibrations in the room. Especially if you have it connected to something like a splitter. I would suggest wrapping your splitter in duct tape, or getting some higher quality wires.

I see this happen all the time with my guitar amplifier, and the radio transmitter for my MP3 player, when i hit bumps and the transmitter box hits the sides of the cup holder you can hear audible noises from the stereo speakers.

More likely it's sounds getting into the splitter instead of the wires, while you will hear things through just the wires, something like a splitter box would be much louder

 

[SCPD]

I would go with TrenchFeeder or Wvscanner's suggestions. Where I was going was if you had other microphone options other than Microphone (Realtek High Definition), you could use that. Line in is what is generally used.

 

[Nate1n22]

The only other option is realtek digital output.

One thing I did notice, is that in Speaker Properties on the levels tab the Microphone is muted. I did this because if it wasnt muted you could hear noises from the microphone through the laptop speakers.

I guess I could just live with it

 

[SCPD]

Digital output wouldn't make since in my opinion. I currently use Line In due to it supporting stereo (I don't use 2 feeds but nice to have it in case). I would recommend switching to this if you have one available. If not, it would benefit you to get a USB sound card as this should isolate your problem!

 

[Nate1n22]

All I have is the headphone in and microphone in. Maybe I'll try getting one of those usb sound cards.

 

[Northerner71]

You said that you have a splitter that feeds one plug to the line/mic in and the other goes to headphones/speaker? I know from past experiences that speakers/headphones can act like microphones. When I was a kid I realized that if I plugged my headphones into the mic slot that I could record subtle noises. This may be what is happening to you. Just a thought.

You shouldn't need that. The headphone and microphone slots are actually built into your existing soundcard
