Converting 24bit wav to 16bit wavpack - more noise than flac (FIXED)

[Phazma]

I have tried to convert a 24bit wav file to 16bit (with the batch converter), once as flac and once as wavpack and when trying a nulltest I noticed that the noise floor in the wavpack file is 6dB higher than in the flac file. Basically I get peaks of -96dB (makes sense) on a nulltest with the flac file and -90dB (huh?) with the wavpack file. Is that normal? Wouldn't that mean that the wavpack file has only 15bits of resolution instead of 16?

Thanks for spotting this, it looks like there's an inconsistent rounding (truncation) applied when writing in WavPack's 16-bit mode (vs .wav or .flac). Fixing.

I see.. glad I could help and thanks for fixing!
