Single wavpack + cue to many wv and lower quality (still lossless).

I have an album in a single wv file with its cuesheet and I want to convert it into a single file for each track.
The wv file is about 2.15GB and looking into the properties of one of the tracks in FB
I see a sample rate of 192.000 Hz, 32bits per sample and 7392 kbps as bitrate.

I would like to end up with separated tracks with a sample rate of 41.000Hz and 16bps,
still in WavPack: would you mind helping me to get to there, please?

Will it be a lossless process?

Thanks.

"Of course" it will not be lossless, but it might very well be transparent to the ear.
But it need not be, because e.g. fb2k will clip if a floating-point signal above digital full scale is converted to integer. Run a ReplayGain scan. What does the peak say?

Scanned as "album".

Album peak is 0.981031
Track peaks are from 0.704497 to 0.981031

Thanks.

Hi there,

Do you mean 44100 Hz and 16-bit? (Just double checking!) <- Bitrate would be ~950 kbps and lossless.

Firstly you might need to get the Free Encoder Pack if not already installed.

Secondly do you have a preferred Resampler DSP installed? (I like Case' SRC Resampler myself)

  • Load the CUE into a new playlist, select all tracks, right-click and Convert > select '...'
  • Click 'Output format' > select WavPack > Edit button > choose your compression options with the first two sliders (how long encoding takes verses filesize, 'normal' and '3' is probably fine) > click OK
  • Set the 'Output bit-depth' box to 16-bit > select Dithering: Always (* I think so though not sure) > click Back
  • Click 'Destination' to choose where you want the files > choose a filename pattern > click Back
  • Click 'Processing' and under DSP, on the right side, click the '+' next to your Resampler of choice > on the left side, click '...' next to Resampler > select 44100 Hz (different Resamplers have more advanced options here) > OK > click Back
  • Click 'Other' and make sure 'Transfer tags' is ticked > click Back
  • Review everything and finally click Convert.

* What is the recommendation on dithering in this scenario? Used when converting to lower bit-depth?

(Hopefully I did not miss anything?)

Then you should be fine using anamorphic's description.

Thanks to everybody.

I was already doing the right thing but I overlooked the way to choose the
fixed output bit depth so it was left on "auto" and finding a source with 32bit
it converted with the same depth.

Thanks again.
