Getting Started > Configure Outputs

•VERTEX lets you select between preview audio i.e. for programming and live audio for the final playout.

•You can assign preview and live audio to your ASIO or standard audio cards or interfaces. You can switch the audio clock between standard audio and ASIO.

•For each system you can set Windows volume, live and preview volume.

Preview and Live Audio

There is a main difference between preview audio and live audio:

Preview Audio

•Preview audio plays out all audio from all playback mixing engines - That includes all playbacks in PME live and all playbacks in one (or maybe more) preview PMEs.

•Preview audio is played out from every system in your project.

Live Audio

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

•Live audio is played out by an defined audio system that could be set for a canvas or a whole system.

By default live audio is played out for all canvas on the same system. It is possible to define a certain audio system for a canvas.

Workflow for Audio Output Setup

1.select a standard audio device for your system

2.select an ASIO audio device, if connected to your system

3.define audio devices for live audio and for preview audio

4.check sync-clock settings (sync clock is changed when live audio device is set)

5.adjust volume settings for your system

6.do final adjustments like audio offset or advanced settings

Audio Settings for a System

ASIO Lock Buffers	Default: disabled Enable recommended if you use an USB audio device.
Live Mute	Default: disabled When enabled, live audio output is muted.
ASIO Audio Mode	Select whether the ASIO audio device should be used for Preview Audio or Live Audio. The difference between the both is explained above. For high quality live output, we recommend an ASIO audio device.
Audio Preview Mode	Choose between a monoaural fold-down, a stereo mix of your preview listening or just keep the channel mapping one-to-one.
Standard Audio Mode	Select whether the standard audio device should be used for Preview Audio or Live Audio. The difference between the both is explained above. For high quality live output, we recommend an ASIO audio device.
ASIO Device Status	Shows the status of the ASIO audio device you have selected. Shows the number of output channels that are being used by Vertex, the sampling rate that is detected and the total number of outputs channels of the interface. For DANTE cards with a high number of channels: reduce channels in Project Settings to ensure a better audio playback performance.
Wave Device Status	Shows the status of the selected Standard Audio Device. Shows the number of output channels that were detected by VERTEX.
Windows Volume	Sets Windows system volume for the selected VERTEX system.
Live Volume	Sets the master volume level of the live audio output for this system.
Preview Volume	Sets the preview audio volume level for this system. For Preview Audio Mute, please use the mute button in the status bar at the bottom of the UI.
Audio Offset	Sets a global Audio offset for this system, for example to adjust synch issues in audio and video playback. Values are set in milliseconds. Negative Values: Audio is sent out later. Positive Values: Audio is sent out earlier.
Audio System	Defines on which VERTEX system live audio should be played out. By default and when working only with a local system without session members, this is set always to the same System. Switch the system in backup scenarios where another VERTEX system should take over the audio playout.
ASIO Audio Device	Select an ASIO interface from a list of all available interfaces that are connected to your system.
Wave Audio Device	Select the standard audio device from a list of available Windows audio devices in your system.

information Using Dante PCI or USB Audio Devices:
Use Yamaha products only with Intel CPUs as AMD CPUs are not supported. Yamaha products have per default 128 channels activated. You might need to change this in the project settings in order to avoid performance issues.
When using Dante Virtual Soundcard make sure you set it to 16bit and 48kHz. Recommended settings for ASIO devices is 16bit/ 48kHz with a buffer size of 1024 or higher. Focusrite USB devices may require ASIO lock buffers.

Mute Preview Audio for local System

The status bar provides you quick access to mute preview audio on a VERTEX system

Channel Routing

Audio channel routing is done on clip container or track level.
Audio from each single clip container can be routed freely to the available channels of the audio device.
Please read topic Audio in the chapter Working With Content.

Sync Clock Settings

When switching between audio devices, VERTEX also changes the sync clock source.
Assume that the audio output generates the clock for a playback.
Please double check the settings and the clock source.

Advanced Audio Settings

Open project settings to set advanced audio parameters.

ASIO Thread Priority Highest
Enabled per default: ASIO processing gets highest Windows 10 thread priority to ensure best audio processing and playback performance.
Disable for a better system performance. ASIO audio processing will not be done with highest thread priority anymore.

Disable Audio Waveforms affects the display of waveforms in Sequence Editor and Inspector in order to save CPU resources.

Disable Embedded Audio Extraction if you want to suppress processing of the audio track in your video content.

Force Audio Conversion (16bit 48kHz) to convert all audio formats in your project.

ASIO Output Channel Count
Number of channels that are being processed by your ASIO device driver. By default (0), channels are processed as set up in your ASIO driver settings.
Set to the desired value if the number of your channels has not been detected correctly by VERTEX. Also, to reduce channels due to performance reasons ( e.g. for DANTE physical or virtual sound cards).

Set back to 0 to reset.

Buffer and Latency for Wave Audio
Set to optimize the audio playback quality before VERTEX sends audio to your Wave Audio device.
