About busses and master dynamic process

[jadiae]

Can somebody tell me any different on BUSSES compressor(or limit) and master limit?

What the main reasons to use compressor's role in the bus?

And what the main reasons to use compressor's(or use a compressor then through a limit) role in the master 2TRACKS?

Please..and thanks all the predecessors

Can somebody tell me any different on BUSSES compressor(or limit) and master limit?

What the main reasons to use compressor's role in the bus?

There are many many reasons as to why you do things when mixing.
Parallel compression is one of those reasons why you would put a compressor on a bus and then send that track to that bus, post fader.

Another reason is you want to send multiple tracks to one compressor.

And what the main reasons to use compressor's(or use a compressor then through a limit) role in the master 2TRACKS?

Because you want to compress or limit the entire mix.

Here is some info on compressors I wrote. Its the basics of a compressor

hope this helps you,

main reasons to use compressor's role in the bus?

To glue the instruments together, lets say the drum bus so they sound like glued together, or guitar busses.

Compression in the entire mix, is for similar reasons to glue the mix together.

Also sometimes certain compressors make audio punchy on the busses and on the mix to make it sound extra gritter.

+ 1000 the above

also, don't use compression to "make it louder"
use it to tame peaks / add a tiny bit of punch/glue before hitting the limiter/AD

Very thank CJ Mastering ;manman;Ged

My English is poor, but i very want to understand ...


And why compression can glue different instruments busses together?Because the dynamic approach？or compression can make new "tone" for every instruments busses?or...?

Any Help?

Thanks in advance. Any suggestions will be appreciated.

When you place a compressor or limiter on the master, the gain reduction is usually broadband, and can be triggered by any loud frequency component in your mix. For example, a loud bass drum hit would cause audible modulation of other signals in your mix.

Among other things, bus compression prevents certain signals from modulating others. For example, suppose you had a drum bus with compression, and a separate guitar bus. The loud bass drum hit would cause gain reduction within the drum bus only, and it wouldn't modulate the guitar bus (or any other signal or group of signals in the mix).

Another benefit of bus compression is that different groups of instruments or vocals benefit from different compressor settings, or completely different compressors, for that matter.

You should also look into what has become known as the Michael Brauer Multibuss technique, which basically uses multiple stereo busses with different processing to handle different frequency ranges within your mix. Again, this prevents one group of signals from causing unwanted modulation of another.
