In my opinion, you either have not tested Tunebite or you have no ideea about how it works.
It’s true that I was wrong about recording the other sounds of the computer, if they appear while converting a song, but that’s because Tunebite records everything that goes out from the sound card compared to MuvAudio, which creates a virtual device through which it isolates the recording process, but honestly, how many times did it happen to record other sounds too? I never had such a case.
But let’s clear some things here, before you spread false information.
The volume level:
At first run of Tunebite, a wizard detects your soundcard and optimizes the sound level. This works in the following way: the wizard plays a very loud sound considering the volume level of the media player to be at 100% and reduces the sound level to an optimum level so that you won’t get any clippings. And you should make a difference in understanding the recording of music: Sound level is measured in decibels which sets how loud the output file is and your so called “resolution”, which actually is the frequency at which the sounds in a song are played, is measured in Hertz or Mega-Hertz, is not touched at all by the sound level. You can only take the sound volume (the decibels) to a smaller value not to a higher one.
The presets of lame encoder:
Tunebite offers a simple way to choose from the various formats that the lame encoder offers. Those VERY IMPORTANT pre-compiled settings are just some normal formats that lame has, but have also received a name tag, to be able to choose easier from the wide range of settings that lame has.
So I’m sorry if you are not able to decide what setting is best for you and you need a name tag for that.
And about the quality of music, you must be a real audiophile with extrem hearing capabilities if you can hear the difference between the pure digital conversion and digital-analog-digital conversion. In theory, yes, you are are right, digital is better quality. But experience has taught us different.
The only major difference is that MuvAudio makes the whole process faster, up to 5 times.
And with a line like this:
“No need to upgrade from 3.1 to those other operating systems just because they have nicer gadgets that will probably never be used at least for the average user.”
you are missing the point totally. If you haven’t realised by now, there is a huge difference between a simple tool and an operating system 
All said and done, in the future do some research work before posting such opinions.
P.S. Don’t take it personally, I just wanted to make some things clear in this competition between Tunebite and MuvAudio
