Description
This component automatically decodes HDCD streams contained in several supported lossless containers, including .WAV, .FLAC, .WV, and .TAK. It also supports scanning files for HDCD features in use to report in a list.
Extra info variables
This component makes several info variables available for title formatting scripts.
- %__hdcd_peak_extend%
- Peak Extend (PE). Will be "yes" or "no".
- %__hdcd_gain%
- Low-level gain adjustment (LLE). Will be "yes" or "no".
%__hdcd_transient_filter%
- Transient filter (TF) indicator. Will "yes" or "no".
- %__hdcd% or $info(hdcd)
- Summary of HDCD content detected. Empty string means no HDCD flags detected. "yes" means PE or LLE detected. "fake" means an HDCD stream was detected, but it no PE or LLE flags, thus there's nothing to process. If only TF flags are present, it's still "fake" because those are only informational.
An excerpt from a status bar script using all of them:
['| 'HDCD: %__hdcd%: PE: %__hdcd_peak_extend%, LLE: %__hdcd_gain%, TF: %__hdcd_transient_filter%')' ]
