I KNOW YOU ASKED THAT QUESTION FOR SHO BUT LEMME RESPOND BY SAYING HIS BEATS PROBABLY SOUND GOOD OUT THE BOX SO TO SPEAK… HE HAS GOOD ARANGMENT AND INSTRUMENT USE AND EVEN A GOOD SET OF EARS CAN'T KNOCK THAT SKILL!!! SECOND… THERE ARE SOME VERY GOOD PLUG INS BUT NONE CAN MAKE A BAD RECORDING SOUND GOOD SO TO SPEAK…

NOW KNOWING THAT, ALL AN L2 LIMITER IS GOING TO DO FOR YOUR TRACK IS ADJUST OVERALL VOLUME BY COMPRESSION/LIMITING. 

THE PROGRAM YOU USE IS PREFERANCE.. AS LONG AS THE PROGRAM CAN OUT PUT AND INPUT A HIGH QUALITY WAV FILE SAY 24 BIT 96KHZ OR MORE IT CAN BE USED TO MAKE COMERCIAL MUSIC…

AS FAR AS VOCALS GO THAT IS A WHOLE NOTHER BEAST… A GOOD VOCAL SPECIFIC MIC IS ALWAYS THE BEST STARTING POINT IN A DAW RECORDING… SECOND WOULD BE A LEVELING COMPRESSOR AND THIRD WOULD BE A GOOD EQ BUT WITH OUT FIRST HAVING THE BEST POSSIBLE QUALITY RECORDING NONE OF THESE WILL HELP YOU HEAR THE QUALITY YOU ARE ASKING FOR… AND LASTLY… GOOD MONITORS SET UP THE RIGHT WAY AND USED THE PROPER WAY AT A LESSER VOLUME WILL DO MAGIC ON ANY MIX…

IF NONE OF THESE THINGS ARE ATTAINABLE GO FOR OUTSIDE MASTERING AND DON'T SKIMP… PEOPLE WHO CAN “REALLY” MASTER MUSIC HAVE THE RIGHT EQUIPTMENT FOR THE JOB AND HAVE BEEN DOING IT LONG ENOUGH TO PROBABLY TELL YOU EXACTLY WHAT YOU ALREADY KNOW ABOUT YOUR MIXES WHEN YOU HEAR THEM IN YOUR CAR OR ON THE DJ'S LOUDSPEAKERS AND YOU WANT TO TWEAK IT… << NOT IMPLYING ANYTHING BOUT ANYONES MUSIC JUST STATING A VERY WELL KNOW FACT IN THAT HAVING SOMEONE ELSE MASTER YOUR MUSIC IS ALMOST ALWAYS THE WAY TO GO FOR A COMMERCIAL RELEASE NO MATTER THE BUDGET…

AND AS FAR AS DITHER… ONLY USE DITHER ON A MASTER BUS AT THE FINAL MIXDOWN OR THE MASTER STAGE… “WHEN SHO USES IT.” BECAUSE DITHERING COMPRESSES FILE INFORMATION AND CAN GREATLY REDUSE BLURING WHEN A LOSSY FILE IS REDUCED TO A LOWER QUALITY…AND ALWAYS LEAVE HEADROOM EVEN IT IS -.1 FOR YOUR OWN PLEASURE OR -5DB FOR AN OUTSIDE MASTER CAUSE CLIPS CAUSE DISTORTION AND DISTORTION SUCKS!
