Hello there!
For those who just want to answere my question;
So, whats the big difference between 44100Hz to 48000Hz?
For those who want to know why I would like to change the sample rate;
I've had this problem with FL Studio and exporting tracks, it came up like 2 weeks ago.
I'll try to explain even tough im sick and has a fever.
When I listen to the track in FL Studio the track sounds, hm, like its speeded up, like when you have a sample that is supposed to be on C5 and you press the C6 key in the piano roll, when I later export it as an mp3, wave, ogg whatever, it goes back to its normal state (It's just frustrating when it sounds like this in Fl and like that when you export it). So I've been trying to solve the problem, and I succeded!
When I change the sample rate from 44100Hz to 48000Hz or higher it sounds like it should in FL Studio.
Or when I change to ASIO4ALL v2, but I prefer to use Creative Asio.

I believe your problem has to do with using sounds or samples which are 48khz (or higher) but fl studio is trying to play them back at 44.1 khz resulting in them being sped up (compressing, and likely discarding some samples, in order to fit into the 44.1 sample rate?). I would think that FL Studio would have real time sample conversion though so i'm not too sure about this.. Maybe it relies on samplers to do this instead? Been a long time since I used FL..
There is no big difference between 44.1 and 48 khz, not perceptibly anyways to most people. 44.1 is the CD redbook standard (all CD's are rendered at 44.1 khz) 48 khz is used, I think, as digital video standard more than anything else. Generally speaking it's always best to work at the highest sample and bit rate your hardware will allow as it gives you more headroom and clarity while mixing, even if you'll end up downsampling later to CD or lossy mp3 format.
The difference between 44.1 and 48 khz is extremely subtle, however, the difference between 44.1 and 96 khz is much more pronounced. The higher the sample and bitrate you run at, however, the more strain it puts on your computer, especially if you're using a sampler which uses a 44.1 library (many if not most do) which will mean the sampler will upsample to your projects sample rate in real time eating up processor cycles).
Basically, if whatever samples you're using play back correctly when your project is set to a 48 khz rate, then it's likely they're 48 khz samples. You will get the best audio quality with them if you just work at 48 khz and simply downsample at the end when you're ready to export your song. Either that or downsample the waves you want to use to 44.1 with an external program, or use a sampler which does this for you (pretty sure most do, such as kotakt or sampletank), which will, technically, anyways, reduce their quality though it may not be noticeable and then you can work at 44.1 khz
