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
window and the Play window.

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.
