FLAC files from Acoustica not the same as WAV

[Freddyy]

Saving a file as FLAC is not perfectly lossless...

You can check this by generating a signal inside Acoustica and then saving it first as WAV then as FLAC.
For 16bit the difference is at -90dB, for 24bit the difference is at -138dB.
Very small differences, so no reason for panic. But it's still a difference.

I discovered this after I generated some test tones, a mix of WAV and FLAC files... then when using them for testing I noticed that something isn't right...
I hope this gets fixed, but in the mean time maybe it will help someone.

Sounds like a difference in dithering?

This is just a slight DC offset due to different interpretations in the PCM to float conversion and nothing to worry about, really.

No, nothing to do with dithering. You can try it yourself, it's easy.

It's not a big problem, it won't make any music sound worse.
But when I had to deal with it doing tests, it made me scratch my head and waste some time, because I never expected this to be the cause... In the end, it makes me lose confidence in saving as FLAC from Acoustica.

Yeah I think this should be fixed, even if it's a tiny difference. Lossless formats should be exactly the same.
