I am thinking about bulk converting my wma collection to flac using dBpowerAMP. I am a little confused about the flac compression option. The original wma file is 29.7 MB. FLAC with 0 compression converts to 33.3 MB and with the 8 compression setting the file is 30.3 MB.

Which compress option shoud I choose? I thought FLAC was supposed to compress better then wma but it appears that the wma file is a little smaller.

thanks

Hi,

According to some other threads Flac does not compress better than Windows Lossless. I have never tested the theory myself so I couldn't say. Really when you are talking about many files with such huge sizes, a few kb here or there isn't going to make much of a difference anyway.

As far as Flac compression options, do whatever you feel is best. Almost everyone that uses flac tends to use settings from 4-6 because higher settings vastly increase the encoding time and show a very poor rate-of-return in terms of file size.

Hope this helps,

ss.

Thanks, I ran a few tests and 7 or 8 are very slow. The difference in encoding time from 3 to 6 is 21x to 18x not a big deal. 4 sound like a good compression to use.
