wavpackenc
WavpackEnc encodes raw audio into a framed Wavpack stream. Wavpack is an open-source audio codec that features both lossless and lossy encoding.
Example launch line
 gst-launch-1.0 audiotestsrc num-buffers=500 ! audioconvert ! wavpackenc ! filesink location=sinewave.wv
This pipeline encodes audio from audiotestsrc into a Wavpack file. The audioconvert element is needed as the Wavpack encoder only accepts input with 32 bit width.
 gst-launch-1.0 cdda://1 ! audioconvert ! wavpackenc ! filesink location=track1.wv
This pipeline encodes audio from an audio CD into a Wavpack file using lossless encoding (the file output will be fairly large).
 gst-launch-1.0 cdda://1 ! audioconvert ! wavpackenc bitrate=128000 ! filesink location=track1.wv
This pipeline encodes audio from an audio CD into a Wavpack file using lossy encoding at a certain bitrate (the file will be fairly small).

Properties
bitrate
“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
Default value : 0
bits-per-sample
“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
Default value : 0
correction-mode
“correction-mode” Wavpack-enc-correction-mode *
Use this mode for the correction stream. Only works in lossy mode!
Flags : Read / Write
Default value : off (0)
extra-processing
“extra-processing” guint
Use better but slower filters for better compression/quality.
Flags : Read / Write
Default value : 0
joint-stereo-mode
“joint-stereo-mode” Wavpack-enc-jsmode *
Use this joint-stereo mode.
Flags : Read / Write
Default value : auto (0)
md5
“md5” gboolean
Store MD5 hash of raw samples within the file.
Flags : Read / Write
Default value : false
mode
“mode” Wavpack-enc-mode *
Speed versus compression tradeoff.
Flags : Read / Write
Default value : normal (2)
