R128Scan [obsolete], Now implemented by bundled foo_rgscan Options

[kode54]

This component has been obsoleted by the ReplayGain scanner bundled with foobar2000 version 1.1.6.

I have produced a scanner interface almost entirely from scratch, based on libebur128. Basic information and a binary are posted here, and the full source is posted here, but I warn you, it isn't pretty.

It writes -18 - LUFS to the normal ReplayGain track and album gain level tags, and optionally scans for the "true" peak by resampling the signal to 192KHz first, using the foobar2000 resampler service, but this is disabled by default because it has a pretty heavy speed cost.

No attempt is made to support reading or writing the EBU R128 "standard" of tags proposed in this topic, because that is beyond the scope of a mere scanner component. The player core must first support representing that information internally with its binary ReplayGain information structures, and then every input component that supports reading and/or writing tags must be modified to support these changes.

  • Fixed channel mapping setup for non-stereo files.
  • Added an abort check to the scanner processing loop just in case.
  • Changed the scanner results to a modeless dialog to get rid of the Windows 7 taskbar progress indicator artifact.
  • Changed all applicable get_item() calls to [] operators.
• Version 1.10 - 2010-01-26 10:34 UTC:
  
  • Changed the "true" peak scanner to always use an upsampling factor of 4 instead of a fixed sample rate of 192KHz.

  • Fixed mixed up infinity/NaN in ebur128.cpp.
  • Fixed rg_offset to return the correct invalid gain constant when the result is invalid or out of range.

  • Fixed albums-by-tags scanning mode to include the last album detected in the batch.
  • Disabled multi-threading in debug builds.
  • Fixed "true" peak calculation to instantiate the resampler for more than just the first track in the album.
  • Restructured "true" peak calculation resampler code to properly handle the last chunk produced by the decoder

  • Fixed RG result info display when there are results from more than one job in the batch.
  • Fixed RG scanner to remove the current job's track names and update the display on I/O error.
• Version 1.1 - 2011-01-26 03:45 UTC:
  
  • Fixed RG info applying filter result finding function to actually return the item indices so that album set tags are written correctly.

  • Album scan mode now keeps track of the sample rate and channel information across tracks.
• Version 0.0 - 2011-01-26 02:18 UTC:
  
  • Started project.

foo_rgscan already has a function to apply the gain correction to MP3 files. Adding that to foo_r128scan would be redundant, not to mention I would have to code it from scratch, since the foo_rgscan code I have from 2004 did not have the mp3gain capability added yet.

Yes you are right、Of course　I understand it that only MP3(without e.g. vorbis read vorbis comment in ffdshow and mesepack ds filter)
I wish it is come true in the near future by this wonderful idea
