Effects- Amplitutde and Compression

hello everyone.

would please explain dose compression ?

thank much.

compression 1 of useful effects there is, used on majority of tracks whether speech or music.

 

any sound record has dynamic range--which difference between quietest part of signal , loudest.  in ideal world leave is, of time when you're mixing, if set things loudest peaks, quiet parts lost.  or, when listening mix on headphones on noisy bus or something, hear quiet bits you'd have have volume turned loud parts hurt ears.

 

...and that's compression does.  allows control dynamic range of recording.  typically, you'd set turns down loudest bits , either leaves quiet bits along or, sometimes, can turn quiet bits while limiting loudest parts.

 

the trouble controls set compression effect can bit complicated learn.  easiest (and useful) 1 in audition effects/amplitude , compression/dynamics processing.  default setting graphical interface rather knobs , numbers.  if spend bit of time looking @ blue line gives (and maybe examining of presets) can see how that, putting marks on blue line , dragging them, can set things so, example, nothing can go louder -6db while things between -30 , -15 made bit louder (don't take numbers example way).

 

by way, compression used feature called "make gain" raises levels compensate the limiting may have applied peaks.  can either within compressor or using "normalise" feature under same amplitude , compression menu.

 

fyi, besides dynamics processing mentioned, audition has several other compressors--single band, multiband, tube modelled , on.  different things won't try confuse discussing them.

 

finally, if want read on more details of compression/dynamics processing, can have @ dynamics processors -- technology & applications on "rane notes" site.  it's hardware compressors ones in audition work same , gives description various controls are.

 

hope helps.
