all this so I can free up space and still have good quality for archival.
If transition between source tracks is gapless, you can get audible clicks between tracks after resampling.
Interesting. I've never noticed this issue using the "Resampler (Sox)" component in foobar2000. Typically, I'm converting FLAC 24/96 or 24/192 to 16/44.
Edit: Wasn't one solution to use "Don't reset DSP between tracks" in foobar? Maybe you have set this and never had to wurry.
@lvqcl, care to test how well the LPC predictor from Vorbis would mitigate this in your SoX resampler?
The OP says these are 44.1/24, right? Then ... no resampling!
If you use guard against clipping and convert tracks separately, it can change loudness difference between tracks in album.
Theoretically, you wouldn't want to add any noise to vinyl. But, the dither is very low level compared to the existing vinyl noise so it won't do any harm.
If you have "image + cue"
BTW, I wonder what would be the reasons to use a less than stellar resampling. You do this once and for all
Does "sox INFO gain: 0.534dB not reclaimed" mean that you lose half a dB and potentially go from 16 bits resolution to 15.9 bits resolution? Not sure if I would bother ;-)
One thing I noticed though is the difference between the original 192/24 and the 44.1/16 (-0.2dB, resampled and dithered via SoX) spectogram, the resampled one looks more smudged, or smeary, don't know the right word.Is that how it's supposed to look after resampling or did I do something wrong?
