Will take a look for R15

I would certainly not want any EQ applied that is not correct. Either you get it right, or you don't do that at all. Altering audio with the wrong EQ is worse than not offering the option.

Myself, by the way, I use the foobar2000 music player, and apply de-emphasis EQ on-the-fly. That is, I don't do anything about the audio in the files, just tag them, and the fb2k component does the rest.

(BTW, why are you using WAV?)

The beauty of having the option to apply a preset "de-emph" EQ is just that....it's optional for those who need/want to use it to de-emphasize their music files but won't affect anyone if they choose not to use it. It's a win-win for a subject that has generated multiple requests over the years.

Currently, I rip to hard drive with DBPA, then have to use a separate program (WaveEmph) to de-emphasize the files. It would be great to have a de-emph option in DBPA, even if it's only as a preset EQ.

(As far as using WAV, I made the decision before ripping any music that I wanted it stored in a totally uncompressed format. I don't use any form of compression whether it be lossless or otherwise. Storage capacity is not an issue these days and DBPA's tagging capabilities allows me to have WAV files with decent tagging.)

DBPA's tagging capabilities with WAV files is an AWESOME feature!!! It's why I made the decision to purchase DBPA.

Well that just moves the question one step: why on earth insist on that nonsensical constraint. Anyway, dBpoweramp can let you store uncompressed FLAC (by way of the verbatim blocks I guess), and then in the very least you get a checksummed format that can verify that your files are not corrupted.

As for a de-emph DSP: well by all means, but do not just implement a dirty approximation. Either do it right or not at all.

Off topic I suppose, but it always amazes me that WAV advocates completely miss the advantage of FLAC files that allows one to always easily check that the files have not been corrupted by use of the self-contained checksum data within the FLAC file. Perhaps that is correlated with their misunderstanding of how lossless works (thus their aversion to FLAC in general). I suppose it is like a religion, dunno....

The reason I asked Spoon for a limited approach to the Pre-emphasis issue is that he had already indicated in past posts that he was not interested in pursuing a full fledged fix for the pre-emphasis issue.

With that in mind, I was hopeful that by presenting an OPTIONAL solution to the issue that would require minimal work on Spoon's part, it would possiby help resolve this issue to a large degree without requiring a lot of time on Spoon's part (hence the post title of "Please Just Throw Us A Bone").

Those of us that have a lot of earlier CD's and continue to pursue purchasing more early mastering CD's to avoid today's compression and brickwall issues would be very grateful to Spoon for at least supplying this option to us so that we do not have to look to additional software outside of DPBA to deal with our pre-emphasis tracks. If some don't want to use the De-emphasis EQ, then this solution won't affect them in anyway.

(As for formatting, I never understand why compression proponents feel the need to try convert others to their formats. I have no interest in having this thread divert to that discussion. I have plenty of storage space and am very happy with DBPA's wav capabilities. I certainly have my reasons for using WAV and I have no intention of changing.)

As I said, it was off topic. And I have no interest in changing how you do things and did not suggest that you change your method. I have just found in the past that many users of WAV files had no idea that WAV files do NOT contain the ability to self-check for corruption with internal CRCs (as a FLAC can do). And when informed, many reconsidered their approach. But this has nothing to do with compression or no compression or storage space (dbpa will create an UNCOMPRESSED FLAC file). But to be clear, I'm not suggesting you change the way you do anything. I'm just providing info that other users of the forum *might* find useful. But I didn't mean to hijack the thread as this is not about file format. I apologize for that.
