Choosing Sequence Bit Depth
The bit depth setting in the Sequence Settings window determines the bit depth
whenever you output or export your sequence. However, sequence audio is always
mixed using 32-bit floating-point values.
Note: The Aud Format column in the Browser and Item Properties window always
shows the internal mixing bit depth of a sequence, whereas the Sequence Settings
window shows the bit depth used if the sequence is exported or output via an
audio interface.
