No, but its isn’t free, so using less of it for no extra cost will always be cheaper than using more of it.It isn't as though data storage is expensive.

WAV is the format that the original CD has the music on it. 16 bit resolution and sampling rate of 44.1 kHz. Playing the WAV files taken from the CD means that no further changes/processing is done and that the SQ is at its best.
Correct. I thought everyone knew that? Guess not.Fretless wrote: ↑Tue Nov 07, 2017 4:09 pmWAV is the format that the original CD has the music on it. 16 bit resolution and sampling rate of 44.1 kHz.

Preferably use a secure rip program like EAC (Exact Audio Copy) that checks to see if it has accurately copied all of the data from the CD.
Actually, not true, the data on the CD is actually just 16 bit two channel PCM as a bit stream with a couple of error correcting codes and a table of contents. WAV is what you get when you look at the audio data on a computer. Its how the driver maps the continuous data stream split at the offsets in the TOC on the red book disk.WAV is the format that the original CD has the music on it.
Oh, yes, naturally.
Hmmm, you really need to blind test this. You should be comparing two absolutely identical files, FLAC is lossless, so the conversion from FLAC to WAV should be perfect, or your software is making alterations to the original files.Fretless wrote: ↑Tue Nov 07, 2017 1:13 pm In my own deluded, obsessive striving for the perfect sound - and a laziness in not wanting to be hassled unless it's absolutely necessary - I have just carried out experiment No.2.
Making a new rip of the Hyperborea CD, this time doing the normal compression process to FLAC. I then used DbPowerAmp to decompress the FLAC file back to WAV. In theory the conversion to FLAC should be bit-perfect, providing scrap-for-scrap identical playback data. So reconverting to WAV ought to be exactly the same as the direct-from-CD original.
A/B -ing the two WAV-encoded files did (for me - or am I just fooling myself?) provide differences in SQ. The original being tighter and more sharply focused in detail, the compressed/decompressed file sounding a tad 'woollier', warmer and ever-so-slightly less detailed. Yes, I'm hair-splitting here but this is my perception and I want the best I can get.
My guess is that the enfolding/unfolding processing of the FLAC engine adds a tiny bit of coloration to influence the sound in the way that jitter from a cheap coax cable would. Loss of focus and a veiling effect.
Decompressing the existing FLAC's will be OK for some albums - but not for others, so it looks like I'll be having to re-rip a large part of the CD collection (again).
