Range Mixdown
The Mixdown function lets you combine a selected range into a single audio object. The objects involved are then removed from the tracks. You can use the feature to free up resources as real-time effects are rendered, to indicate finished ranges as such, or just to simplify the project.
To perform a range mixdown, select File > Advanced Export > Range Mixdown from the menu.
If the bit depth of the objects in the project is more than 16 bits, you can decide in a query dialog whether the new file should be saved in 32-bit float or 16-bit format:
-
32 Bit (Float): The new file will be saved in 32 bit float format. Select this option if audio material in 24-bit or 32-bit float format is involved in the mixdown and the high resolution should be preserved.
-
16 bit (integer): The new file will be saved in 16 bit format. Select this option if 24-bit or 32-bit float objects are involved in the mixdown and the final product is to be used in the form of 16-bit audio (e.g. as an audio CD). In this case, the 24/32 bit files in the project are converted to 16 bit using dithering.
The object with mixdown file is placed on the active track. If this track was used in the project, i.e. contains volume, pan settings or effects, these now also affect the mixdown object. Since the mixdown should sound exactly like the corresponding area in the project before, it is recommended to create and select a new track before executing this function.
