Trouble recording. mic doesn't pick sound up

I have a neighbour that is harrassing me and my family. We are building a case against him. I dont want to bore you with the background story but amongst other things he stands near the very thin walls and screams racist slurs and profanity between 6 and 9 pm, trying to get us to move. We are very much stressed out by this.

I can hear this very well in my living room and even upstairs. I have installed audacity to record this. Unfortunately it does not pick up on the sound. If he screams i keep seeing a flat, straight line. I do see some movement in the colored bar but it is not much.

I am using a Toshiba laptop with windows 8.1 64 bits
Processor: AMD E1-2100 APU with Radeon HD Graphics 1.00 ghz
RAM: 4 gb
Audacity 2.2.1

I am using these microphones, attached to a stethoscope and a splitter that is connected to the microphone audio jack.

How can i get the microphone to be more sensitive?

If i right click on the microphone and click options… i can choose a frequence between 1 and 100. Could this make a difference?
Also… on the bottom left i can choose projectfrequence in hertz. Will it help to adjust that?
I don’t know what to do. Pls help.

Thank you for your time.

Does your laptop have separate microphone & headphone jacks or a single combo jack? If you have a combo jack a regular headphone plug will work but you need an adapter to make the microphone connection.

Then make sure you’ve selected the external mic as your [u]recording device[/u].

And if you can hear it (without the stethoscope) the microphone built into your laptop should be able to “hear it” too, although you may have to be quiet on your side of the wall to minimize the “background” noise. I assume the stethoscope does make it easier to hear (with your ears)?

You might be better off with the laptop because the microphone is a native device and you don’t have to go through the adapters, special cables and oddball drivers.

You’re also better off with a company that does services like this.

Audacity doesn’t do surveillance, conflict resolution, advocacy or law enforcement. And even if we did, self-administered recordings like this aren’t real for the people in a position to do anything about it. Recordings are amazingly easy to fake which is why a bonded company has to do it.


I’m closing this topic as it involves information that could be material evidence in legal proceedings.
While we are very happy to help users of Audacity software with technical support, for legal issues, advice should be sought from legal professionals.
