Hi. I these questions are copied from a forum and perhaps you can help me to answer them. I) For some codecs (I think MP3 for example) there was that issue that you have different sample/frame/whatever lenghts than in raw/wav encoding, thus if you encode a file to mp3 the lenght is not exact and some digital silence is added. Is the same thing the case with flac (thus the original file would be modified)? II) As im using index-based ripping (and want to store my files in like this) I have some wave files that are very small (e.g. 34 frames only or even less). Is it possible at all to have such small flac files? III) I've read about the CUEsheet feature of flac where you can store the data of cuesheets (at least indices and so) as searchpoints in flac. But the format seems to be in milliseconds while in CDDA frames are exact. Is it (because one would have rounding errors) not adivsable to use this feature, and store one big flac file with those cue information transformed into searchpoints in flac?

And afterwards I'd be able to restore/decode it to the single files, right?! btw: This is not the right place to ask,.. but is it planned to add a standard to ogg (and thus flac) like ogg comments,.. but for additional stuff like lyrics,.. or CD-cover art and so on? Thanks for your help so far :-) Best wishes, Chris. -------------- next part -------------- A non-text attachment was scrubbed...
