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).
