I'm new to WV files and am a bit confused.I understand that WAVEPACK supports both lossy and lossless compression.Is there any simple way to know if a WV file that I downloaded was compressed originally as lossy or lossless??? I mean other than my trying to examine/analyze the decoded WAV myself manually or something like that. Is there a way that WAVEPACK can tell me without my having to figure it out?THANKS for any helpful hints.
If you use the hybrid command then you'll probably get lossy. You can check with Foobar whether your's are lossless or lossy, the birate and size also can tell you it's lossless or lossy.
So it sounds like you can't know for sure if what you are downloading came from a truly lossless source (?).
Yeah, you can try to look at the decoded WAV, analyze it different ways like in a waveeditor in spectral view, etc etc etc but WAVPACK doesn't appear able to tell you how the WV file was created in the first place (right?). Unless I'm still misunderstanding something? I confess to not understanding exactly what this means - "If you use the hybrid command then you'll probably get lossy." Isn't the "hybrid" command something to do with how the WV was created in the first place, rather than how you decode it to WAV later? Because I have no idea how the file was actually created (hybrid command or not), I only have the WV file itself and instructions to decode it with "wvunpack" (with no command line options).
There are 2 different questions:Was the source lossy?Is the WV lossy?
I am used to working with FLACs where I know that the encoding process produced a lossless file in comparison to its input...
I'm only asking the 2nd question. I want to know if the WV file which was created from a WAV that previously had no lossy lineage was created by WAVPACK as LOSSY or LOSSLESS

QuoteI'm only asking the 2nd question. I want to know if the WV file which was created from a WAV that previously had no lossy lineage was created by WAVPACK as LOSSY or LOSSLESS1) wvunpack -s filename.wv can tell you if WV file is lossless or hybrid (lossy)2) Winamp - View file info...2) Foobar2000 - Properties. Or you can create another column in playlist that shows %codec_profile%.

@slipkidFirst, I'm sorry for not understanding what you wanted to ask correctly.The short, correct answer to your question is "No, you can't do that. Wavpack, FLAC, APE... no lossless audio compression can tell you that."<snip>
