configuration_asio-audioThe ASIO Audio section in the Configuration Tab allows setting up connected a ASIO sound card for Pandoras Box. ASIO sound cards are used by dedicated Audio tracks in PB Manager software or (since version 5.1) in PB Player / Server running as Client or Master. Audio tracks allow playing back ASIO wav files while being synchronized to a master clock.
If you are interested in sound cards available for Pandoras Box, please check the chapter "Input and Output Cards".

Video to audio synchronization

Choose with the "Site" drop-down menu a Pandoras Box system, and assign an available ASIO device with the "Device" drop-down. Decide by ticking the check box "Use Audio Clock as Master" whether this system should send the master clock. Please note, that there can be only ONE Master in the system! The ASIO clock will be the system’s master clock and all video layers on all Clients within the entire PB network will be synched to it.

It is possible to output ASIO on multiple systems but it is not possible to synchronize the audio on more than one system while playing back. If you output ASIO on another system (than the one that generates the master clock), THEIR audio tracks cannot be synched while playing back. They will be triggered in synch but as soon they are running they are in a free-run mode.

Timecode master – not timecode slave

The ASIO clock will be the system’s Timecode master. It is not possible to have two master clocks in a system; ASIO and SMPTE can’t be used simultaneously.

Sample accurate audio and master volume

Choose a sample rate from the "Sample Rate" drop-down list (41 kHz, 44.1, 48 kHz, 96 kHz as supported by the sound card). All sound files within the project should be created as wave files with the same sample rate.
Please note that the ASIO Tracks will play mono and stereo PCM Wave files (16 or 24 bit) with the sample rate that is preset in the Audio Configuration only, there is no sample rate conversion. Each sample will be played back 1:1.
There are test files with various sample rates and volumes in the Stock Assets folder.

The fader sets the master volume of your ASIO sound card. Value Range: -96 dB (muted) up to 6 dB (max.). Default value is -9 dB.

Multi-channel ASIO output

The ASIO protocol allows multichannel audio output, depending on the sound card up to 64 audio channels are supported. In order to assign a track to a specific audio channel of your ASIO sound card, please refer to the Track Inspector.

This list reads the sound cards settings and gives you an overview how the channels are routed in the sound card.

Playlist Option
With a selected ASIO device, you can choose the option "Play Audio Files in Parallel with Playlist Entries". This automatically plays the "according" audio file with the video in a Playlist. The audio file does not need to be part of the project, but it has to be named in the same way as the video file and needs to be located in the same folder.
