Transcoding can mean two things - converting all your WMA files to FLAC in one shot or using slimserver to play them by converting the audio data on the fly. I think the two of you are talking about different things. Anyhow, that's not the issue, you're talking about volume correction. There are a few different techniques for doing this but most of them involve analysing the whole file (or sometimes whole album's worth of files) and writing the results of the analysis into tags. WMP does this itself for WMA files, ReplayGain is similar and works with a few file types including FLAC. iTunes can also do it - again using it's own tagging scheme. Slimserver will read the tags that it understands and use the data to adjust the playback volume accordingly. It certainly supports ReplayGain tags, and I think it also supports whatever scheme iTunes uses. I don't _think_ it supports the volume tags in WMA files (although I may be wrong). What this means is that if you play the WMA files as-is through slimserver you won't get any volume levelling. However, if you convert your collection to some other format (like FLAC) you can then add ReplayGain tags, and then you'll have the levelling. -- radish ------------------------------------------------------------------------ radish's Profile: http://forums.slimdevices.com/member.php?userid=77 View this thread: http://forums.slimdevices.com/showthread.php?t=27739 _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss
