Working with Third Party Applications
8.3 Controlling Audio Bit Depth
The creation of an audio file with a particular bit
depth (or resolution) is controlled through an
application’s recording settings. These settings
are typically adjusted in an audio device
configuration menu or in a recording setup
window just prior to recording. When recording
is initiated the AES16 will generate audio
samples of the desired resolution.
Bit depth control during playback of an audio
file is also an application issue. When a file is
played, the recorded bit depth is read from the
file’s header by the application. The application uses this information to set the resolution of the
AES16.
The AES16 supports file types with 8, 16, 24, or
32 bit word widths. Note that 32-bit files contain
24-bit data with zero data in the least significant
bit positions.
The Lynx Mixer application displays the
currently selected bit depth for each device just
above the device name in the Record/Play
window.
8.4 Full Duplex Operation
The sixteen audio devices of the AES16 operate
completely independent in terms of whether they
are in recording or playback modes and their
associated audio files. This implies that the
devices can operate simultaneously and support
the so-called “full duplex” mode where, for
instance, the AES16 Record 1 device is
recording while the AES16 Play 1 device is
playing.
Although the devices act independently, when
multiple devices are being used to record or play
multiple audio files simultaneously, the AES16 driver has the capability to synchronously start
all devices with sample accuracy. This is
especially important for maintaining
synchronization during playback of multiple
devices and overdubbing.
By using all of the record and play devices,
sixteen-track recording and playback is possible.
Again, control of this multi-channel operation is
simply a matter of device selection in any
compatible multitrack audio application.
