Virtual Audio Cable Adobe Audition



Adobe Audition is a digital audio workstation from Adobe Systems featuring both a multitrack, non-destructive mix/edit environment and a destructive-approach waveform editing view. When I use MME in Adobe Audition, I have the option to configure the output to be a virtual audio cable: However, when I switch to ASIO, I don't see where I can. Virtual Audio Cable (VAC) is an audio bridge between applications that transmits sounds (audio streams) from app to app, from device to device. VAC creates a set of virtual audio devices. Each device simulates an audio adapter (card) whose output is internally connected to the input, making a loopback. The Virtual Audio Wire (VAW) is an open source Virtual Audio Device (VAD) project its function is to provide Virtual Audio Devices for multimedia applications such as Adobe Audition, Sony Sound Forge, AIMP Player, Broadcasting softwares etc in Windows platform (similar to JACK Audio Connection Kit (open source but use ASIO - technology), Virtual Audio Cable (VAC) and Virtual Audio Streaming (VAS)).As we know that commercial softwares are not free and not open source. Adobe Audition v.3 Record, mix, edit, and master digital audio files with powerful tools that bring flexibility and control to your desktop studio. Easily create music, produce radio spots, and restore imperfect recordings. Bring audio and video together using smart.

Noise reduction & restoration

De noise:

simple just move the slider to 0-100% to reduce amount of sound.
Enable output Noise only: listen only the noise level useful to cut the noise.
Then apply gain to get actual value from reduced lower sound.
Pros: simple just like noise reduction technique in other softwares like audacity.

Adaptive noise reduction: (more parameters)

standard noise reduction only for post processing, not for live processing, so adaptive noise reduction must for live podacasts or streaming games.
Note: it’s realtime processing so need little bit extra cpu power otherwise delay due to heavy processing.
Reduce Noise By: 6-30db better, 20db by default,
Just it substract the noise. (you can monitor it while adjusting)
Noiseness: it’s indicates amount of noise in original audio.(so we can reduce accordingly)
Fine tune noise floor: manually adjusting it above or below the automatically calculated noise floor.
Signal threshold: manually adjusting desried audio level above or below the automatically calculated threshold.
Special decay rate: how quickly drops to 60db
Baseband preservation:
Saving frequency of vocals helps to boost audio quality. (Need to know about equalization)
FFT SIZE: length of frequency band. Or how many individual frequency bands are analyzed.
Processing focus:
High frequency focus
Mid frequency focus
  • Techniques for restoring audio
  • Sound Remover effect
  • Automatic Click Remover effect
  • Click/Pop Eliminator effect
  • DeReverb effect
  • Hiss Reduction effect (Waveform Editor only)

Fliter and Equalizer

Virtual Audio Cable Adobe Audition 2019

FFT Filter Effect:

Fast Fourier Transform an algorithm quickly analyzes frequency and amplitude of sound wave.
High pass filter(HP): Passes the high frequency and cuts the lower frequencies.
Low pass filter(LP): passes the lower frequency and cuts the higher frequencies.
Narrow band pass filter/ telephony : 350-4000hz here only the vocals of human to avoid background noise. Telephone uses this spectrum.
Notch filter: to remove precise frequency low 60hz, monitor it just up& down , find a noise in a specific range, then use notch filter and drag drop to remove entire sound.
Tradeoff between frequency and time accuracy.
Lower reduced transient artifacts

Parametric Equalizer in Adobe audition

Q/width: controls width of the effected frequency,
High q value effects low range frequencies (ex 100hz)
Q value which is a ratio of width to center frequency

Amplitude & compression AU

Noise gate effect: stops the noise below noise threshold (ex threshold,-30db then it only passes above threshold db like -29 )
Expander: just like compressor, but it compress the lower noise ex: threshold -30 db compress ratio 1:2
Then 30db becomes 15db if ratio 1:10 30-3db= 27db.
compressor: compress the above limit threshold .
Then compressor threshold limit is -10
attack time: wait before compressing after reaching threshold
Audio
Ratio = 1:2 , before total db level to -1db. Now it’s -5db.
Because it’s compressed remaining 10db into 1:2 ratio means half then 10 becomes 5.
Gain: after compressing the noise level reduces we can apply some gain to -6,-3 or -1 db.
Normalisation: boosting lower level audio signals upto peak level audio signal.(make sure to completely reduce background noise)
Ex: audio track has -15 db , and -10db – 6-db -3db.
When we apply normalisation . All audio singals gained to upto -3db it’s a peak in audio track.
Before applying normalisation make sure to cut excessive wave lengh. So the audio track is innsame wavelength.
Presets: -1db more than -1db or 0 distortion or in bearble sound.
-6 mostly use for voiceovers
-10db some people use it for quite voice but not recommended.
Equalization: plays vital role to remove unnecessary noise based on frequency.

attack & release time

Determines how many milliseconds it takes for the output signal to reach the specified level
(to avoid unnecessary processing at short sudden changes )
Determines how many milliseconds the current output level is maintained
To see good attack and release times for different types of audio content, choose various options from the Presets menu.
Fast attack & release time for drums, music instruments.
You can know by just doing post processing audio. To see how much time the audio at peak level.(it’s a art)
Hold time:

Dynamic processing

Level meter & gain reduction meter:
This works by compressing lower & higher audio signals. To maintain a level.
(Noise reduction done by expander, loudness reduced by compressor, also added bandwidth/frequency specific processing)

Dynamic effects:

Compressor: reducing peak voice with certain ratio
Expander: reducing lower threshold with certain ratio
Limiter: totally reducing noise level for a specific threshold.

Hard limiter effect:

Maximum amplitude:
Input boost: before cutting the audio, we pre amplify the audio to avoid audio clipping.
Look ahead time/ attack time: time to wait
Determines how quickly starts
Release time: time to release back to normal.
Determines how quickly compression stops after reaching normal.

Multiband compressor effect

just like parametric Equalizer it’s also a good & advanced effect to process audio frequently.
Main: compressing at band or frequency specific.
3 bands
Mid: 2k
5bands (not a scientific values)
Low mid: 100-500
High mid 2k to 10k
(select bands by either manually entering frequencies or presets and edit later)
Vocal frequencies at 80hz to 10k
Voice Fundamentals falls beween 80-300hz
bypass: ignore the band
Input level meter:

Mac Virtual Audio Cable

gain: 4db (boost or cut +4db or -4db)
attack: 10ms

speech volume leveler effect

compression effect that optimizes dialogue, evening out levels and removing background noise.
Target volume level (db):
Low settings: amplify speech slightly without boosting the noise floor.
High settings: amplifys entire signal as it drops to close the noise floor
Boost low signals: shorter & low volume passages (for most speech content, skip this for smooth audio)
Minimizes background noise while amplifying and leveling speech content.
ex: -45db to -60db
higher: upper -85db greater background noise but lower amplitude & leveling.
lower: (down -30db) higher amplitude & leveling but background noise also boosts.
Advanced settings:
compressor : maintains strong signal by gain if processed signal falls .

if you unfamiliar with multiband just use tube modelled compressor
we its reduces above threshold in a certain ratio.
More than -1db unbearable sound.
speech leveler (option)
it has gain & compression & noise suppression techniques so use it after equalizer (to get best results)
Avoid over processing.(just focus on audible sound at beginning)

Many computer Sound Cards used to have a ‘virtual’ audio input called “Stereo Mix”, “What U Hear” or “What You Hear”. However, many sound cards don’t support this feature. How do we get this feature back in Windows 10? I’ve found some free software, and worked out how to best configure it so anyone can use it!

What is Stereo Mix?

Stereo Mix allows you to record exactly what was being output to your speakers, without going through any analog/digital conversion. This feature is very handy for recording the audio off a website.

Why was it removed in Windows 10?

Configure Vb Cable

I don’t think Stereo Mix was ever technically removed – it was a driver-specific feature only supported by specific hardware. I’ve still seen it on some Windows 10 PCs, but it’s not as common these days as it used to be. Many sound-cards (particularly onboard sound cards) don’t have this support. This isn’t a case of Microsoft being evil, or backing the recording industry.

What is the official replacement?

Windows now has the WASAPI, which is supported in particular by Audacity and some newer Adobe Audition releases. It presents a specific WASAPI input which replicates the audio currently being streamed to an output.

However, this new feature requires the developers of each program to support it – so this doesn’t really help those of us with a few Adobe Audition 3 licenses floating around.

If you want a simple way to record your computer’s output, use Audacity (it’s free and easy to use for recording). If you want to use another audio recorder… read on!

What’s the solution for Windows 10 Stereo Mix?

I’ve found several programs that promise to let you stream audio between programmes. These include Virtual Audio Cable (VAC), and JACK. However, these programs are quite complicated and aren’t for the inexperienced. VAC is also a paid program.

The best program I’ve found for Windows 10 Stereo Mix is VB Audio Cable.

VB Audio Cable essentially creates a single output and single input. The audio on the output is routed to the input. Any audio program can record this virtual ‘input’.

How to Install VB Audio Cable

Installation is very simple. Here’s how you do it…

  1. Download VB Audio Cable from the website
  2. Unzip the downloaded file
  3. Run VBCable_Setup.exe or VBCable_Setup_64.exe
  4. Step through the wizard
  5. Optional: reboot once you’re done

Once it’s installed, go to Control Panel > Sound and check that your new audio input and output has been created.

To make it easy to record, set both the input and output as your default devices.

Adobe Audition Virtual Audio Cable

VB Audio Cable also comes with a control panel. It requires no installation… just open VBCable_ControlPanel.exe from the Downloaded ZIP folder. In here, you can select Sample Rates up to 96Khz. You can also monitor audio levels.

How to Configure Adobe Audition

Virtual

Adobe Audition may not choose these new audio devices by default. Here’s how to select it:

  1. Open Adobe Audition 3 (or restart it if it’s already running)
  2. Go to Edit > Audio Hardware Setup
  3. Click “Control Panel” and select your new inputs and outputs
  4. Click “OK”
  5. Select the new inputs and outputs from the Edit View drop-downs

How to Listen To What You’re Recording

When you set the VB Audio Cable as your new Default Playback Device, you won’t be able to hear the audio through the speakers. Thankfully, Windows 10 comes with an easy solution.

Virtual Audio Cable Adobe Audition 8

Open up the Sound Control Panel again, go to the “Recording” tab, and select “Properties”.
