One of the many endless debates in computer audio is WAV vs FLAC.
Some people report an audible difference. Most of the time in favor of WAV.
Other says this is plain make belief, placebo, etc because when FLAC is converted back to WAV the result is bit identical.
Others argue that the processing power to convert FLAC to raw PCM is higher than in case of WAV so this might affect the timing (jitter).
An obvious downside of WAV is the lack of a tagging standard resulting in poor portability of the tags between media players / playback devices.
FLAC has a well-supported tagging schema.
From R14.1 on dbPoweramp has an option: uncompressed FLAC.
Now you have your uncompressed WAV with the tagging capabilities of FLAC.
Looks like the best of both worlds.
