If I converted the 32 bit to 24 bit, it was the same result.
When I converted to 16 bit, it worked well.
When I converted a 16 bit wav to 24 bit, it also worked well, without any unwanted noise.

The original file was recorded by a friend with MAC OS (with an 'off topic' DAW), I use Windows 10 OS.
I don't know does it matter or not...

@jcksn82chrvl Good question. Is it a standard PCM WAV file?

How can I check this?
From Acid it looks like Wav, 24 bit.

I have recorded from my sound card directly in 24 bit with ACID pro.

When I listen the recorded file, it is also produced this noise.

I had to set the sound card properties to 16 bit, and it was OK again.

@jcksn82chrvl There is a free tool called MediaInfo which will give you a detailed description of your audio and video files.

Thanks. I have checked it.

Yes, it is a PCM Wav 32 bit (that was one of the original files, which was problematic).

So, I don't know what happens.

I have to work with 16 bit files?

Update.

Media info says, about the original problematic file received from my friend:

PCM (IEEE)

My 24 bit recorded file with ACID (also noisy):

PCM

@jcksn82chrvl There is an option for a much more detailed description. Maybe it tells you more.

I have to work with 16 bit files?

No, Acid definitely supports higher bitrates.

@jcksn82chrvl Additionally, please check whether your sample rate and bit depth settings for your playback and recording devices in Windows are set accordingly. Maybe this is causing your problem.

Sorry for the absence, I could not deal with topic in these days.
I will check this!

On the other hand, when I zoom into the noisy waves I can see the noise...
I hope the playback options will solve this...

I have checked the sound control panel properties.
I don't have as much oportonity as I can see on the linked page.

I have only 3 choice on my sound card's output:
44,1 kHz 16 bit
48 kHz 24 bit
48 kHz 16 bit

If I check my notebook's speaker output I have more choice.

Here I have 44,1 kHz and 24 bit.

I could set up the same bitrate and frequency everywhere:

But when I record something, I have faced the same thing :(

When I record it with Aud***ty with the same setting, it is good... :(

Playback is also good in that program.

When I open it in ACID Pro, it gets noisy :(

I have missed the check the microphone settings. It was 48 kHz. I have set it to the correct value according to the playback and device settings.

I recorded another sample, but there no change. Still noisy... :(

Maybe I should have to increase the sample rate?
