What is the implication of ticking "Use AccurateRipResult from ID tag" in the settings? For example, when I transfer a batch of files from one HDD to another, I run PerfectTunes AccurateRip on the transferred files (as an extra check on the files not being corrupted by transfer, etc.). But with the "use AR result from tag" checked, does PerfectTunes no longer actually check the file and instead just read the tag AR value and *assume* the underlying audio is OK and matches the AR data?

Correct, in your instance you would want it unchecked.

Hi

I found this thread in my attempt to understand better what PerfectTunes R2 Beta 5 does. And as soon as I unticked the box and rescanned, I suddenly had 49 CDs with ripping errors, eventhough these were files that had been ripped Accurately with DBPowerAmp 15.x. I checked the files with Foobar2000, and it says the files are ok. See the below files

So, I guess my question is how good files suddenly became bad files?

OK. Got them now. Spoon will have to comment on why an AR match initially, but not with PerfectTunes.

p.s. your foobar2000 picture just shows that the file is not corrupted. PerfectTunes didn't say it was corrupted, just not a match (different things). You can use the File Integrity checker in foobar2000 to also run an AR match (but you have to select ALL the album files, right click > utilities > then choose the AR check option).

When I do that with this album I get:

"No such disc found in the AccurateRip database.
Please make sure you have selected a complete disc rip with correct track order.
If the disc contains hidden tracks, you can only verify it through a matching cuesheet with hidden track information intact."

The album plays fine btw.

I release an update to R2 PerfectTUNES beta in the next 2 weeks, it will show the AccurateRip disc ID for the export, it is interesting to see if it matches the one on the file.

Hi Spoon

First of all, I have to complement you and Gary on the fact that you always respond and take the reported item seriously. It as an Asset to your software (pun intended!). That said, I ran a little experiment. My reported reported case concerns a file that is by now at least 6 months old so it is not beyond comprehension that somehow it did get corrupted. As an aside, it would highly puzzle me as to how that happened as my files are fairly secure on read-only drives.

Anyway, I did the following test.
1) Re-rip the CD to a separate location using DBPowerAmp 15.3 (original rip was with DBP 15.1)
2) Verify it with Foobar2000 1.3.8
3) Verify it with PerfectTunes R2 Beta 5

The results are:
1) Perfect! AccurateRip at level 200! No problemo :-)
2) Oops. Same message as previously in Foobar2000
3) PerfectTunes reports only 11 out of 13 tracks as Accurate. Now not only track 13, but also track 1 is not Accurate. Both files play fine in Foobar2000

So, I'm beginning to suspect this is a problem in both Foobar2000 and PerfectTunes. That's sort of a relief to me as it means my files don't mysteriously get corrupted. But we do now need to understand why PerfectTunes cannot confirm the DBPowerAmp result.

I hope this helps you somewhat.

Here the PerfectTunes output.

I'm not using the PerfectTunes beta. But I too can report that I've seen some examples where PerfectTunes doesn't give me a match after the fact even though the CD was ripped with AR and initially had a match. But I can't provide any examples of this at the moment (in the past, I followed up with additional checking and the files were fine, so I didn't really pursue any questions).

Hi

I just reran my tests with Beta 7. I get four types of error messages that I cannot explain. In all cases, the album was originally ripped acurately.

1) "Cannot check: incomplete album". This despite the fact that all the tracks of the album are present. See the screenshot of the Skunk Anansie album.
655

2) "Cannot Check: Track Different Length Than CD Original". Again, the album was ripped accurately. The only thing I can think of is that the DSP for cutting off silent parts of the album plays a roll. But on this AC/DC album there is nothing like that. Can the error message be improved to at least highlight the tracks that display the symptom?

AC/DC - High Voltage [AccurateRip DiscIDs: 009-000fc139-00729e5e-650a6609] Cannot Check: Track Different Length Than CD Original

Track 9: D:\Public\Music\AC-DC\High Voltage\09 - High Voltage, AC-DC.flac

3) Ripping errors when there are none. I already gave an example earlier where a perfect rip with DBPoweramp was on a subsequent check with AccurateRip immediately flagged as not being accurate. The accurate rip DiscID on all tracks is identical to the one in the log.

4) I find that on occassion I get random corrupt file messages. I have two identical libraries. One being the back up of the other. I get these messages more frequently with files on the NAS than on the hdd. So, perhaps a bandwith issue. When I rescan, the file will be fine. Also, Foobar2000 does not flag the file as corrupt.

2) Audio CDS always have a minimum track interval, that is based on sectors of 2352 bytes each. That means if your tracks are not this exact length, then they have been altered in some way, perhaps silence was removed from the track. Either way the track is no longer matching a track off a CD.

3) Do you have the log entries for both perfecttunes and dBpoweramp?

4) This might also relate to *1, the tracks are read in a simple fashion, there is no way for PerfectTUNES this wrong (it matters not if the files are on a local HDD or network share, they are still read the same way), however it is known that certain NAS do not deliver the files correctly if under high load. You are best to copy the tracks to your local system then try a full rescan.

So, when DPA rips should I assume that it compares that rip to the database prior to applying any DSP thingies like "Silence Track" removal etc?

Spoon

Yes it is the data as it is straight off the CD, for example if you applied a volume normalize to 50% of the volume, you would still get an accuraterip verification when ripping.

But I can rerun with Beta7 if you want.

The conversation about DSP and at what point in the process DBPowerAmp compares to AccurateRip got me thinking. As DBPowerAmp compares to AccurateRip before DSP is applied, perhaps the DSP was causing something to be changed to the file. So, I re-ripped without any DSP enabled other than ReplayGain. And then the problem disappeared. Specifically, the DSPs for removing silence on hidden tracks and silent track removal caused the issue. The lesson therefore is that if you want to use PerfectTunes for verifying your files, you need to have ripped them with only non-destructive DSP options enabled.
