More Information on Configuring Session
To play back and record audio in Session, Session
must communicate with your sound card. On first
launch, Session attempts to choose the first sound
card containing both an audio input and audio output,
effectively making this connection automatically. If
Session is not able to select audio inputs and outputs
automatically, it will open the Audio Hardware dialog.
If the process is successful (Session does not open
the Audio Hardware dialog automatically), but you
cannot play back or record audio with Session, you’ll
need to open the Audio Hardware dialog by choosing
Options>Audio Hardware.
The Audio Hardware dialog
contains the following options:
▸ ASIO/WDM Switch
This control switches the Audio Hardware
dialog of Session between ASIO and WDM
mode. For best performance in Session, use
ASIO mode. Consult the documentation for
your sound card to determine if it
supports ASIO.
▸ Output and Input Device Selectors
These controls set the Output Device (sound card) through which Session plays
audio, and the Input Device (sound card) from which Session records audio. It is
recommended that you select the same sound card for audio input and output.
▸ Buffer Size Selector
This control sets the latency of Session. See the “About Latency” section found later
in this guide for additional information.
▸ Use Low Latency Streaming Checkbox
When checked, Session attempts to open the selected audio interface in low latency
mode (WDM Kernel Streaming). While most sound cards should “open” in this mode,
results vary widely based on the sound card in use. See the “About Latency” section
of this Quick Start Guide for further information on this.
