What is compression in audio editing softwares (audacity &, Adobe audition)?
compression is a technique to reduce higher volumes above the threshold. By a certain ratio.
Parameters
Threshold: -10
attack time: 5ns
NewTek NDI for Adobe Creative Cloud is the only software plugin for Adobe’s industry-standard creative tools that simplifies review and approval processes, facilitates collaboration between teams in different locations, and accelerates live-to-air editing. You set your output device in Audition to 'Cable Input', in OBS set your Mic to 'Cable Output'. You won't be able to hear yourself, Audition's output will be fed to OBS through the virtual cable.
hold time: *
We can understand that, if audio level goes above -10db for more than 5ms.
Then compressor will attacks reduces noise by 1:2 ratio, once it reaches after 50ms release time compressor stops if any gain input not there, if gain is there it will boost and stops.
If once again audio hits above threshold it follows above steps in live audio processing. Post processing it’s take sometime to apply entire audio track.
So this how a compression works in obs, audacity audition etc.
Multiband compressor
A advanced effect available in Adobe audition but not in audacity.
It’s have flexibility to compress the audio in specific frequency.
we can skip a band , or we use only 1 band out of 3-5. more control.
In audio processing compression takes 2nd to 3rd part.but Equalizer takes first place.
attack & release time , threshold and gain parameters plays vital role.
Over compressing & boosting gain leads unwanted such as background takes main place.
Compressor presets for Adobe audition & audacity available.
Vocal enhancer:
above 10db it’s cuts and between 20-10db boosts to improve vocals.
high attack & release time useful for drums ,& fast beats.
Compression vs hard limiting
most of the times compression not alone avoid noise distortion .
Adobe Audition Observed
some mobile audio editors like lexis audio editor won’t have hard limiter effect.
Hardware compressors vs mixers vs audio processing softwares

Adobe Audition Live Audio
Hello and welcome to a quick(ish) 5 step tutorial on how to clean up your staticky microphone for a better sounding stream. For this tutorial you will need a copy of both Adobe Audition and Virtual Audio Cable (VAC) installed onto your computer with default settings. I hope you find this tutorial useful, or at least insightful for your own methods!
Step 1) Setting up Adobe Audition.
first create a new multitrack session in AA using the default settings
Step 2) Setting up your mic.
On the first track of your multitrack, click the drop down that says 'default stereo input' and select 'audio hardware'
Next, change your default output to Line 1 (this audio device was created when you installed VAC)
and change the latency to 50 (this number may vary for you, play around with it to find a setting that wont cause any audio stuttering)
Step 3) Setting up the audio pass-through.
back on the main window, on the first track, click the 'R' button in the upper right, followed by the 'I' button. this will let our audio pass to our Line 1 in realtime (there is in actuality some latency, but non to really be mention worthy)
Step 4) Setting up the noise reduction.
on the left, you will find an 'effects rack' tab, that should already be selected. on the first row click the right facing arrow, go down to noise reduction/restoration, and select adaptive noise reduction. a window will pop up after this. you can play with the sliders if you like, but the default setting works well. you can close that pop up window after.
Step 5) Setting up the mic in OBS.
Last step woo! open up OBS, go to the settings, then click on audio. under the 'microphone/auxiliary audio device dropdown you want to pick your Line 1 (virtual audio cable) device. that's it! your mic is now being filtered in realtime by AA
Disclaimer
Something to keep in mind while using this method of mic cleanup is that it DOES use some CPU. the CPU use on my system is negligible however, only ever peeking at 2%. this is with a Intel Ivy i5-3750k. Your results may vary
