Recording pure noise from microphone instead of vocal voice

Hello
I pledge your mercy and patience. I am not any good with anything I have to do to get out of this trouble.

I’m suing Audacity 2.0.5

Usually I just use shure SM58 microphone connected to stational computer via Audiolink III miditech interface through direct USB 2.0 port or sometimes a hub and everything works fine. In Audacity I choose MME for recording source, Linear entry (miditech) mono.
And I can hear my voice going out of speakers and if I record, Audacity catches everything perfectly.

But today I did everything as before and the programme started imho malfunctioning. I’m not complaining as I paid nothing to use it.

My vocal still goes through the speakers and it’s good, same as before
though in Audacity when I click Record I get incredible raw noise. When I click “silence” on “mute” it still records the track.
When I listen to what I just recorded, it is pure noise. Though the loudness of voice is higher or lower depending how loud or how near to the microphone I am.
Now, when I tried to export the project to a file, it got sped up. either to .wav and mp3.

Here is a link (to .wav file and audacity project. During recording I said ‘pulled to bits left rotting on the ground’ and got this:)

please help. and take your time, I’m in no hurry.

So no, it’s not “pure noise.” It’s noise with your voice mixed in.

AUP is not a sound file. It’s a list of instructions to tell audacity what to do with the stuff in the _DATA folder which is where the sound actually is. So either include the _DATA folder of the same name, or send a real MP3 or WAV file.

You may have thought you did send an MP3 file by the filename. You need to use File > Export to get a real stand-alone sound file.

The second link doesn’t go anywhere.

When was the last time you restarted your computer? Koz

You should never use a hub for audio. Mice, keyboards and other peripherals are the only things that should be connected to computer USB hubs.

Ok, I replugged the Miditech cable back to USB 2.0 port of my PC Motherboard. It’s still the same. The speakers play what I sing into Microphone, and Audacity still turns it into noise.

Here’s a .rar with project where I just recorded myself singing random vowels.

Change the USB cable.

Restart the computer.

Make sure Edit > Preferences: Recording has “Audio to Buffer” set to 100 milliseconds or higher.
