Audio

 

Use the Audio tab to configure audio mixing and output options:

  • Audio Configuration: Configure the audio routing for the presentation:

    • Mixed Audio PCM Only: Multiple PCM audio sources (for example, from a video and audio file playing simultaneously) will be mixed into a single source for audio outputs. Differing sampling rates (e.g. 44.1 kHz vs. 48 kHz) will be merged into a single rate of 48 kHz. This setting also allows for dynamic adding and removing of audio sources while audio is already playing.

      • Auto level volume: Check this box to level all PCM audio streams on a particular audio output to a similar volume level.

    • Mixed Audio PCM / Compressed: The behavior is the same as the Mixed Audio PCM Only setting, but compressed audio is supported as well.

    • Fixed Audio: Audio sources are mixed only if their sampling rates match. If you attempt to add or remove audio sources while audio is playing, playback will fail.

  • Audio: Set the Minimum Volume and Maximum Volume for the audio output (0 – 100).

  • HDMI: Set the Minimum Volume and Maximum Volume for the HDMI® output (0 – 100).

  • SPDIF: Set the Minimum Volume and Maximum Volume for the SPDIF output (0 – 100).

Note

The Maximum Volume settings for Audio, HDMI, and SPDIF will be overridden by other volume settings in a presentation, including the Initial Volume setting for a zone and volume commands attached to events or states.
