Audio

VERTEX runs two audio engines in parallel: Preview Audio for monitoring and Live Audio for playout

Volume levels can be set per Clip Container/Clip or for a whole System

Various options enable you to route audio channels, basic equalization, A/V offset and more.

Preview and Live Audio

The main difference between preview audio and live audio:

 

Preview Audio

Preview audio monitors all audio signals from all playback mixing engines - That includes all playbacks in PME live AND preview PMEs.

Preview audio is played out from every system in your session.
 

Live Audio

Live audio plays out only audio from playbacks that are running in PME Live.

Live audio is played out by a defined audio system that can be set for a canvas and/or for a whole Vertex system.

 
By default live audio is set to the same system for all canvases. But it is possible to define individual audio systems per canvas.

 

Default Configuration (System Audio Settings)

The system's built-in Windows Wave device to monitors Preview Audio: Wave Audio Mode is set to Preview.

Connect an ASIO interface for live audio playout: ASIO Audio Mode is set to Live.

Audio Settings for a Clip Container or a Clip

For a Clip Container in a Sequence or a Clip in a Playlist there are different options to set or route Audio.
To see all available audio settings for an item, select the "Audio"-Tab in the inspector.

 

audio-clip-container

Volume

Adjusts the volume level for the Clip Container

Mute

mutes the audio track

Audio

Target field for a secondary audio track. Whether your content has got embedded audio or not, this field is empty.

If you need to add audio to a silent Clip or need to change the embedded audio track, just drag & drop the audio content of your choice from Project Explorer onto this target field.

Clamp Audio to Clip time

Cuts off audio at beginning and end of the Clip Container to avoid sound overlapping when using Audio Offset.

Smooth Volume

Adds a damping to sudden volume changes.

Use Track Channel Map

When enabled, the Clip Container's routing set in its Audio Channel Map is overridden by the channel routing defined in its hosting Track.

Volume Left / Right

Shows level meters in numerical form.

Stereo Pan Mode

Balance Mode attenuates L&R channels according to value/ slider, Mix Mode attenuates one channel while slightly boosting the other.

Stereo Pan

Slider and numerical value field to adjust L/R balance in stereo tracks.

Audio Offset

Offsets the audio track of a Clip Container/Clip to an earlier or later point in milliseconds:

- negative values play audio earlier

- positive values play audio later

Ideal tool to fix minor synchronization issues!

Equalizer

Enable the EQ by ticking the check box. The EQ holds eight bands. Its frequencies are located above the faders and can be altered by clicking on a number and typing in a new value. Faders boost or cut the frequency. Adjust the width (octave) in the numerical values below the faders.

Channel Map

VERTEX's Audio Matrix enables you to route the audio channels of your source content

to the output channels of your audio interface. By default the Audio Mapping is set to 1:1.

For a video containing a stereo audio track this means:

Channel 1 is routed to Channel 1 of the ASIO interface.

Channel 2 is routed to Channel 2 of the ASIO interface.

 

To customize your routing, either use the graphic matrix by dragging the dots in its coordinate system, or use the syntax field below:

Enter e.g. 1@4 to route channel 1 of this clip container to output 4 of your audio output device.

• Use comma separated values to enter multiple routings - eg 1@42@5

Use 1:1 to reset the default audio routing.

A combination of 1:1 and individual routing is also possible - eg 11,2@5

Use 1-10>21 to shift the channel range from 1 to 21

Use #10 to set a new start output channel 10

 

 
Customize your routing:
To route channel 1 of your source to channel 7 in your output
and source channel 2 to output channel 8, the routing syntax is:

1@7,2@8

 

The Syntax for an Audio Routing is

AudioChannel#@OutputChannel#,AudioChannel#@OutputChannel#,AudioChannel#@OutputChannel#

 
To reset a routing, just type in:

1:1

 

Use Track Channel Map

You also can create a Channel Map for an entire Track of a Sequence.
Enable "Use Track Channel Map" in a Clip Container's settings and it will use the routing of the hosting track's channel map.
If this setting is disabled, the Clip Container's proprietary routing is executed.
