I used a translator to translate the German, since I don't know German well. Right now I don't really have standards with audio equipment.
For mixing, production, and to produce the best quality tracks you need to hear through the best quality speakers and through the best quality sound card.
A good sound card can be obtained through companies like M-Audio, The Sound Blaster X-fi is probably the best sound card to get through creative for audio production (getting audigy is still not a standard because anything without D/A converters is considered not usuable to produce professional music if you are using a computer...the D/A converters and firewire ports are what a lot of top audio equipment from synths to mixing consoles would need...many effects use firewire now, compressors, flangers, phasers, EQs, many types of effects).
You need good monitor speakers, usually a couple of hundred can buy you some decent ones. I think by this coming year I'll be able to save up the money I need to upgrade my audio equipment. Anyone serious about music production in general (not just using flstudio, but if you ever wanted to record rock groups, pop groups, country, rap, and electronic music) needs good equipment.
As with mastering, good mixing needs to come first or the mastering won't be good. Some good pointers with mixing are:
1. Use EQ only when necessary (I use it now to modify frequencies that might conflict in the track and produce a muddy or a sound that is too sharp...you can also use the EQ as filters if you want...all's a filter does is cutoff certain frequencies).
2. Use compression on kicks, bass, and to compress the whole track...but don't overdo it. Kicks and bass, always use short attacks and releases if you are looking for a good punchy sound.
3. Always compare your music to professional songs.
4. Experiment - No song will use the same exact compression, the same exact amount of reverb, one track will sound good with a flange on a snare...many won't. You never know what might help the song, or hurt the song.
5. Never be afraid to change anything that doesn't fit. If something doesn't sound right from the get-go, or you are bothered....keep a note of it, because most likely you'll find something better for it as your music progresses.
6. As for mastering, Compression and limiting are always used...but I don't always use limiting. I think it depends how it's used, I usually just compress only. And I do limiting in a sound editting program, once a export my song to wav (and I use the highest resolution and sample rate, before I render my tracks down to mp3 using a sample rate of 44.1 khz. Even though you can render a wav at 96k, and then render it back down to 44.1 khz.......the sound will be more accurate. I learned this in school actually, so I follow it when I use Reason. I don't like Flstudio's rendering as much because there are no options to encode a wav in 24 bit. It's made a bit of a difference. It's not completely noticable. But, if you compare resolutions and sample rates, the higher rates will always sound more full. They have to.)
7. Use Panning, but don't use it on the drums or bass.
I'm still learning a lot. There's a lot of information of audio technology involving mixing, sound design, mastering, recording, arranging, remixing, etc. I'll have a song up this week using flstudio, and it'll have all the instruments that are included in flstudio (I don't have sytrus which sucks, because it is flstudio's best built-in generator - FM synthesis is much more advanced than subtractive synthesis like the 3xosc).
I'll manage though. I'll have an mp3 of the finished track. And a zip file with all the samples and the flp file for people to look at, remix, etc. SLK has done that, and he provided good examples on layering...his layering is very good in his early tracks, if you want a good example ask him for the remix he did of "Countdown" by E2P.
