Description
WavpackEnc encodes raw audio into a framed Wavpack stream.
Wavpack is an open-sourceaudio codec that features both lossless and lossy encoding.

Property Details
The “bitrate” property
“bitrate” guint
Try to encode with this average bitrate (bits/sec). This enables lossy encoding, values smaller than 24000 disable it again.
Flags: Read / Write
Allowed values: <= 9600000
Default value: 0
The “bits-per-sample” property
“bits-per-sample” gdouble
Try to encode with this amount of bits per sample. This enables lossy encoding, values smaller than 2.0 disable it again.
Flags: Read / Write
Allowed values: [0,24]
Default value: 0
The “correction-mode” property
“correction-mode” GstWavpackEncCorrectionMode
Use this mode for the correction stream. Only works in lossy mode!.
Flags: Read / Write
Default value: Create no correction file
The “extra-processing” property
“extra-processing” guint
Use better but slower filters for better compression/quality.
Flags: Read / Write
Allowed values: <= 6
Default value: 0
The “joint-stereo-mode” property
“joint-stereo-mode” GstWavpackEncJSMode
Use this joint-stereo mode.
Flags: Read / Write
Default value: auto
The “md5” property
“md5” gboolean
Store MD5 hash of raw samples within the file.
Flags: Read / Write
Default value: FALSE
