So 10 years ago I decided on ripping to WMA Lossless and haven't stopped. The collection is around 400.
I'm a big audiophile but I also don't want to re-rip if I don't have too. I'm going to go ahead and future-proof with Apple Lossless (not up for debate). Would I experience a loss in quality (and how much) if I allow iTunes (or dBpoweramp, etc) to do the conversion? I tried researching it but could find any info that had been written within the last 4-years (not surprisingly as most wouldn't have waited this long) Thanks ahead for everyones input. |

Lossless encoding means, by definition, that the exact bits from the input file (or CD, etc.) can be reconstructed. This means that no matter how many times you transcode lossless -> lossless, provided there are no bugs in the codecs, you'll still be able to recover the original bits. This means there will be zero quality loss.

Notwithstanding the obvious clue in the adjective lossless…

Lossless is lossless - neat, huh?
 Lossless was lossless four years ago, it was lossless 10 years ago, it'll be lossless 10 years from now. Either iTunes or dBPowerAmp will do a perfect job of converting your WMA Lossless files to Apple Lossless - preserving all tags and album artwork *may* be another matter. I don't know as I've only used the WMA->AAC function of iTunes a few times, but I would recommend converting a couple CDs as a test before you queue up all 400. The only way lossless "can't" be lossless is if the program doing the encoding/conversion f*cks something up before it does the encoding, i.e. EQ, normalization, etc. By default, neither iTunes nor dBPowerAmp will do anything during the conversion, and iTunes can't, no matter what. dBPowerAmp has the option to apply DSP filters during the conversion if you so desire. Edit: dv1989, we have to stop meeting like this!
