WavPack Export Options - Audacity Manual

# WavPack Export Options

From Audacity Development Manual
WavPack is a completely open audio compression format providing lossless, high-quality lossy, and a unique hybrid compression mode. For version 5.0.0, several new file formats and lossless DSD audio compression were added, making WavPack a universal audio archiving solution.

For details pleas see wavpack.com

What you hear by previewing with playback prior to export is what you will get in the Exported audio file.

- When using Export Audacity will only export tracks that are not grayed-out by use of the Mute or Solo buttons in the tracks' Track Control Panels.
- Also note that any hidden parts of audio clips are not exported, see Audio Tracks and Clips.

  Accessed by: File > Export Audio then choosing WavPack Files from the Format dropdown menu.

## Audio Options

### Channels

Sets the number of channels for the exported audio file. There are three options

- Mono: single channel
- Stereo: stereo pair with left and right channels
- Custom mapping: use this to export multi-channel (surround sound) files or to make customized assignments between Audacity tracks and the channels in the exported file.
  - Selecting this and clicking on the Configure button causes the Advanced Mixing Options dialog to appear. For details please see Advanced Mixing Options.

### Sample Rate

Sets the sample rate for the exported file. Default setting is 44100 Hz, which is CD quality.

### Quality

Four options are available:

- Low Quality (fast)
- Normal Quality - default
- High Quality (slow)
- Very High Quality (slowest)

### Bit Depth

Three options are available for bit depth:

- 16 bit - default
- 24 bit
- 32 bit float

### Hybrid mode

Hybrid mode provides all the advantages of lossless compression with an additional bonus. Instead of creating a single file, this mode creates both a relatively small, high-quality lossy file that can be used all by itself, and a "correction" file that (when combined with the lossy file) provides full lossless restoration. This means never having to choose between lossless and lossy compression.

### Bit Rate

This is only available when Hybrid Mode is selected.

There are options from 2.2 bps to 8.0 bps. The default is 4.0 bps.
