+
+Decodes High Definition Compatible Digital (HDCD) data. A 16-bit PCM stream with
+embedded HDCD codes is expanded into a 20-bit PCM stream.
+
+The filter supports the Peak Extend and Low-level Gain Adjustment features
+of HDCD, and detects the Transient Filter flag.
+
+@example
+ffmpeg -i HDCD16.flac -af hdcd OUT24.flac
+@end example
+
+When using the filter with wav, note the default encoding for wav is 16-bit,
+so the resulting 20-bit stream will be truncated back to 16-bit. Use something
+like @command{-acodec pcm_s24le} after the filter to get 24-bit PCM output.
+@example
+ffmpeg -i HDCD16.wav -af hdcd OUT16.wav
+ffmpeg -i HDCD16.wav -af hdcd -acodec pcm_s24le OUT24.wav
+@end example
+
+The filter accepts the following options:
+
+@table @option
+@item process_stereo
+Process the stereo channels together. If target_gain does not match between
+channels, consider it invalid and use the last valid target_gain.
+
+@item force_pe
+Always extend peaks above -3dBFS even if PE isn't signaled.
+
+@item analyze_mode
+Replace audio with a solid tone and adjust the amplitude to signal some
+specific aspect of the decoding process. The output file can be loaded in
+an audio editor alongside the original to aid analysis.
+
+@code{analyze_mode=pe:force_pe=1} can be used to see all samples above the PE level.
+
+Modes are:
+@table @samp
+@item 0, off
+Disabled
+@item 1, lle
+Gain adjustment level at each sample
+@item 2, pe
+Samples where peak extend occurs
+@item 3, cdt
+Samples where the code detect timer is active
+@item 4, tgm
