The 2.3.0 version crashes whenever I tried to run a LADSPA plugin (not even a preview, just run it), so I don't use it. That is a known problem with 2.3.0, and is one of the reasons why 2.3.0 is NOT a release version for Linux. The bug has been fixed in 2.3.1 which is due for release later this mon...

I have a sample with realtek. How do I post it.

See here: viewtopic.php?f=49&t=72887
Short samples (around 5 seconds if stereo or 10 seconds mono) are best posted as WAV files.

Yes it could be done in Nyquist, but not simple to do.
If you know what the exact spacing is between the sounds, then the task is much easier than if that is unknown or variable.
What's the task? Why do you want to do this? What are the sounds?

and shows as 32-bit float when opened in Audacity.

As DVDdoug wrote, that's because Audacity automatically converts them to 32-bit float format.

11025 kHz, mono, 176 kbps = 16 bit
22050, mono, 352 kbps = 16 bit.

Also, just wondering why you are using 32-bit float. That seems like massive overkill considering your original files have a low sample rate (22050 Hz).

if I export as wav the new file shows Bitrate 705 kbit/s

What is the sample rate and number of channels of the exported file? (this webpage can tell you: https://mediaarea.net/MediaInfoOnline )

Feel free to post a few seconds of what you are working on. The two Mahler MP3s sound identical to me. a lot of this does depend on our hearing and audio equipment. Fortunately we can eliminate much of the subjectivity by looking at measurements. For example, as expected, these are not identical, bu...

Perhaps Reaper would suit you better: https://www.reaper.fm/

It is normal for exporting to create a tiny bit of noise due to downsampling from 32-bit float to 16-bit.
The amount of noise in your image appears to be much greater than the expected noise, but could be due to your spectrogram settings.
