R128GAIN: An EBU R128 compliant loudness scanner Options

[pbelkner]

I've just uploaded on sourceforge a first version of r128gain, an EBU R128 (http://tech.ebu.ch/loudness) compliant loudness scanner:

http://sourceforge.net/projects/r128gain/files/

• process single files (tracks):
  
  • In order to just scan and analyze one file (WAV, FLAC or WV):
    
    CODE
    r128gain <file>
  • In order to scan, analyze and tag one file (currently only FLAC, result will be in <directory>):
    
    CODE
    r128gain <file> <directory>
  • In order to scan, analyze one file (WAV, WV) and encode and tag into FLAC (result will be in <directory>):
    
    CODE
    r128gain <file> <directory> flac
• recursively process directories (the content of a directory is considered an album):
  
  • In order to just recursively scan and analyze a directory:
    
    CODE
    r128gain <directory>
  • In order to recursively scan, analyze and tag a directory:
    
    CODE
    r128gain <directory> <directory>
    r128gain <directory>/* <directory>
  • In order to recursively scan, analyze a directory and encode and tag into FLAC:
    
    CODE
    r128gain <directory> <directory> flac
    r128gain <directory>/* <directory> flac

Tagging is currently supported only for FLAC:

• REPLAYGAIN_REFERENCE_LOUDNESS: always -23 LUFS (corresponding to EBU R128)
• REPLAYGAIN_TRACK_GAIN: loudness difference to -23 LUFS in LU measured for this track
• REPLAYGAIN_TRACK_PEAK: true peak measured at 192 kHz for this track
• REPLAYGAIN_ALBUM_GAIN: loudness difference to -23 LUFS in LU measured for the whole album
• REPLAYGAIN_ALBUM_PEAK: true peak measured at 192 kHz for the whole album

These tags should be honored by each Replay Gain compliant media player.

i can't for the life of me get this app to just analyse and then tag, it always encodes the FLAC's again.

Is there any possibility of getting proper switches implemented?
e.g.

CODE

r128gain <switch> <directory> <directory>
switch:
--a --analyse
--at --analyse-tag
--ate --analyse-tag-encode
