Preparing Audio for Distribution
Mixing
rolled out numerous repetitions of the clip, SONAR exports a single clip
that is the length of the original clip and all the repetitions, which is not a
time-consuming operation.
7. Audio Format: ask your engineer what format the studio uses, Windows
(RIFF Wave) or Mac (AIFC).
8. Click the Save button.
9. SONAR exports the project as an OMF file. In the Save as Type field,
select the OMF version you want to save the project as. Version 1 is
compatible with older applications. See your target application’s
documentation for information on which version it supports.
Note: OMF files save the following:
• Tracks
• Clip positions
• Slip edits
• Fades and crossfades (as destructive edits)
The following information is discarded:
•Volume
•Pan
• Automation
•Effects
Dithering
Dithering—whenever an audio signal is converted from a higher-bit
resolution to a lower resolution, it is necessary to apply dither to avoid
introducing undesirable quantization noise or harmonic distortion into the
signal. The purpose of dither is to reduce the resulting distortion by adding
low-level random noise or “dither” to the audio signal. Different
mathematical calculations are used to generate dither, each method has
advantages and disadvantages depending on the particular operation.
SONAR Producer features the Pow-r dithering process, short for Psycho-
acoustically Optimized Wordlength Reduction, which can produce lower-bit
files that sound indistinguishable from higher-bit source files. When this
option is turned on, SONAR uses dithering when you export a higher-bit file
at a lower resolution, or lower the bit depth of a project’s audio files by using
the Tools-Change Audio Format command, or when you “render” audio
(bounce, freeze, or apply effects).
