How can I take pictures with this?

I would like to make sound recordings with this technical equipment. Is the microphone plug in the red circle?
How can I connect the converter to my laptop?
Which programs are available for saving the recording?

It depends on whether you use a cell phone or laptop.

Basically I would rather use the laptop, but if it is easier to implement on the smartphone, then there.

What kind of converter is it, does it look like an analog to digital converter for the connection between TVs and stereo amplifiers?

I thought I needed it. Isn't that so? Is the mic enough?

That will not do.

Your microphone outputs an analog signal and you have a box that has inputs for digital signals, converts them and outputs analog signals. So it's 'wrong'.

You could also simply plug the microphone into a corresponding input on the laptop. Most laptops have microphone inputs.

Oh, would it noticeably improve the quality of the recording, would I use an analog → digital converter or does it mainly depend on the microphone?

Basically, you should have a 3.5 mm stereo jack micro input (symbol of a microphone) on the laptop and thus be able to plug in the microphone directly. The rest are sound settings in the system.

What kind of cell phone do you have? (I only know the method with the cell phone, but I think if you enter it on Google, you will also get websites on how to do it with the laptop.)

Most laptop solutions are very simple. But with your cute little 55 plastic fake; elaborated solutions don't really bring you much.

Your laptop may have installed an analog-to-digital converter. The converter is also not insignificant; but in principle you should also have a proper microphone preamplifier. The signal from the microphone is too weak to operate an A / D converter properly.

A Huawei, it works, but the quality is not exhilarating due to the age.

Do you happen to have something like a "voice memo" on your phone? I personally have an iPhone, so this voice memo app works for me. But it is already installed and does not have to be searched in the AppStore or Google Play.

It can't be used for this, in addition to that the cinch sockets on the converter are outputs, only one signal comes out.

This is an analog microphone, does the laptop have such an input?
