You can attach files to this thread, apparently.
Are there any rules about the samples or could it be any sample that we like? Also, can I attach wma lossless files?
If I cut it more some important parts (where the encoders have problems) are missing. Can I upload it anyway?
1. If the sample contains loud passages at (or close to) full range should the volume be changed before encoding to flac and uploading (to prevent clipping)? If yes - how should it be done? (E.g. fb2k replaygain + diskwriter + (what) dither)
2. I guess many people here who want to upload something use vorbis for ~64kbps bitrates (e.g. I do for ogg previews), so samples that are specifically problematic for vorbis might be overrepresented - leading to a test biased against vorbis. The only solution I see is choosing random samples from random songs but then many will be too easy for encoders...
I think I shouldn't post any Pink Floyd samples?
