MASCHINE 3.1.1 exports some noises when the task has reached my song's ending.

I will add just one fact about Bit depth.

32bit is not opposite of 24 which is the best bitrate because it's giving us bigger Noise floor, that's meaning more space for mix and getting to louder quickly and 32 is related to output meaning you can clip hard but you won't hear it and it's common for Computers to make mistake if Export came from busy Mix with many FX but it's not relevant bitrate so 24 is quality and KHz 48 is maximum for Human ears ( devide 48 by 2 and final output will be 24khz which is more than enough for Music.

In special occasions like surround it's higher the Khz more stable sound will be positioned and now imagine Dolby Atmos or similar Format with 180 Pan positions and that's why 96khz is better because you won't have artifacts or clicks dropouts, in Music if you want higher kHz it's better to use 88 because for the CPU it's easier to compile simple multiplication by two and that is 44 X 2= 88, of course if you have that possibility.

24bit and 48khz is ideal.

It's much easier to understand when it's studies like scientific literature and many other causes led to today's solution, but in the end the conclusion is that for recording it is desirable to have more details 96-192khz.

CThe fact is that we are limited to a certain frequency range of Mechanical Waves-Sound and anything above 10K is a sound that is so fast that it is used for quiet tails of Cymbal and HiHats and above is AIR.

If you can work with the information you have then use it to your advantage but all devices for the dynamic and amplifieing will react to below threshold and you will have noise which is in most cases like Lo-fi FX Samplerate downgrade.

Try to lower the end with Automation on those devices from Compressor EQ Maximizer and Limiters ( Saturation in some cases) and do it just to be sure you tried.

Otherwise it's something that can be removed after on the Exported File and solutions are different from Negative Correlation Phase Reverse -trick

Filter to smooth transition to the silent or Fade Out on right time without destructive results.

I hope that you can at least search those things I wrote for more precise and grammatically correct sentences.
