Headphones Volume

Each audio input can have its own independent headphones volume set.

This is great for situations where you want an audio source such as a microphone audible on the final recording or stream but do not want to hear

it in your own headphones as the slight audio delay coming from your own microphone can be disorienting.

Pre / Post

These audio meters can be used to monitor the audio audio at the pre-effects stage (for any effects, volume or gain, including delay)

and the post-effects stage (after all effects, volume, gain and delay have been applied)


Displays the current audio format of the input


Select the audio channel to use for this input.

If you have a Microphone plugged into the left channel or right channel independently. Select SeparateMono here.

Separate mono allows you to adjust the volume of both mono channels independently from the Audio Mixer.

The audio from each microphone will be audible on both the left and right channels simultaneously.

For finer control of how different channels are mixed. See Channel Mixer below.


Select the gain (or amplification) in decibels.

Gain is added after the compressor. (See below)


Delay the audio source in milliseconds



Compressor is a standard dynamic audio compressor.

Ratio: Specify a Ratio other than 1:1 to turn on the compressor.

Threshold: Specify the sound level for compression. Any audio above the threshold will be compressed (volume reduced) according to the ratio above.

Noise Gate

The Noise Gate is a handy way of reducing noise on an Audio Input such as a Microphone

It works by quickly fading out the audio when it drops below a certain dB (decibel) Threshold

Channel Mixer

The channel mixer can be used to route and control individual channels.

For example if a Microphone is connected that is only audible on channel 1, select L and R

for channel one so it can be heard on both the Left and Right channels on the final output mix.

1,2,.. represent the channels coming in from the source, L + R represent the final stereo left and right channels coming out of vMix and used in recordings and streams.

Audio from sources such as NDI may have up to 16 channels available which can be mixed here into a final 2 channel output.
