WavPack Export Options

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.

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 - this is the default setting even if you only have mono tracks for exporting
• 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.
