Primary Controls
Bit Depth
Selects the output bit depth.
Generally, the Bit Depth should be matched to the resolution of the bounce or export settings of your audio project.
Here’s a chart listing common bit depths for a given type of project.
Project | Standard bit depth |
---|---|
CD | 16 bit |
DVD | 16, 20, or 24 bit |
Blu–ray | 16, 20, or 24 bit |
Mastered for iTunes | 24 bit |
Most DAW’s | 32 bit |
Dither Amount
Controls the amount of dither applied to the signal.
Option | About |
---|---|
None | No dither |
Low | Does not fully eliminate quantization distortion or dither modulation, but can be a good choice for audio that already contains some natural noise. |
Optimal | Excellent quantization performance with a lower noise floor. Recommended for most situations. |
High | Complete elimination of quantization distortion with a slightly higher noise floor. |
Noise Shaping
Option | About |
---|---|
Optimal | Optimizes the dither noise shaping for each combination of bit depth and sample rate. |
None | Flat, TPDF dither. |
Low | Noise reduction: 4.5 dB / Highest peak: 10 dB |
Medium | Noise reduction: 6 dB / Highest peak: 16 dB |
High | Noise reduction: 8 dB / Highest peak: 24 dB |
Good Dither’s noise shaping was designed to be smooth & natural-sounding and to avoid the extreme high-frequency peaks that are common in other dither algorithms. For mastering, we generally recommend using some noise shaping (“Optimal” is a good place to start), but we’ve included a completely “flat” option as well.
