Opus / Re: Can you ABX this song?
Last post by Deathcrow -
First off: There's a significant misconception in that threat, which is that the codec with less differences to the original is the one with the better quality. If a lossy codec throws away more - to the human ear - inaudible stuff in order to preserve audible segments at higher bitrate it is the better lossy codec, not worse. Arguing from such a position basically ignores the entirety of psychoacoustics.

I've tried my hand at ABXing the tracks from that thread. For a second I imagined to be able to hear a difference, but ABX trials quickly proved me wrong. IMHO if there's an audible difference it's so minute that the smallest lack in concentration makes it go away. But admittedly I'm not super good at ABXing. It's also possible that the guy from the reddit thread has some kind of hearing anomaly that allows him to pick up things that we'd miss, because the psychoaccustics are not tuned for his weird ear.

This kind of "spot the difference" game isn't that interesting to me anyway, particularly when it all comes down to listening to the same 2 seconds of a track 50 or more times until you can make out a tiny difference. At that point it's already way, way, beyond what I'd want out of a lossless codec in terms of quality and I'm more than satisified. I'm not going to care about that when I'm just listening to the music.

Opus / Re: Opus 1.3 is out!
Last post by sveakul -
On the decoder side, only two things have changed since 1.2:
  • The minor spec changes in RFC 8251 are now enabled by default (they were there but disabled by default in 1.2), which slightly improves voice quality around 16 kb/s and makes mono decodes default to disabling phase inversions.
  • There's been security hardening improvements, which makes it even harder for someone to cause problems with malicious files. No change in quality.

Thanks very much for the information jmvalin and all your hard work on this terrific codec.

Yes, you need to run File/iPod/Load library which should cause the iPod contents to appear in the playlist view. Then, select the relevant (or all) tracks in the playlist, right-click on them and select iPod/Update metadata.

If you can't see the iPod contents after running Load library, post a screenshot or a video of what happens.
One more point of confusion for me.  I referenced this, https://wiki.yuo.be/dop:config:database. When do you need to both "Update Metadata on iPod" and "Rewrite Database"? Or, is it one or the other?
EDIT": I just mapped the database COMPILATION to %compilation% (w/o the brackets []) as you mentioned above. After doing "Load library", I did both a "Update metadata" and "Rewrite database". Now, Music>Compilations on the iPod is empty again. So, something worked, but not as I expected?
EDIT2: I just removed the mapping. Now, Music>Compilations has the two albums that I tagged with IPOD_COMPILATION as before. What's wrong with the mapping? It seems as if I am getting the database update working?

OT: still 10 is better than any <10. It's not personal here, I don't care about MS, Apple, Linux, BSD or any other, I just use what's usable for my life and work. I use all of them in different areas.

Opus / Can you ABX this song?
Last post by anita22 -
HI! This is my first post, so let me introduce myself first: I'm Ana and I'm a huge enthusiast of audio technology, and state-of-the-art audio and video. Opus... well, what can I say. I'm just in love with this codec. It's a just magical, there's nothing quite like this. At least, that's what I thought before reaching this reddit comment. This guy, apparently (he has actually posted some ABX test), is able to discern Opus @320kbps vs. FLAC, and even vs. AAC, which he believes is superior for this particular tune. He claimed later (in a MP) the difference is easy to spot during 2.08 - 2.15. I just can't. 96kbps is transparent to me. He even says later on that Opus @140kbps sounds like trash. My question is, what do you guys think? Is this a killer sample? Is there some king of bug in the encoder? Does he have those alleged golden ears of which there are no proof of existance AFAIK?

Here is the link to the files, so that you can hear it by yourselves. Tell me what do you think.

The iPod does not look at any tags in the files (other than lyrics) – it looks in its database which this component maintains.

No, the component does not read from a field named COMPILATION in the component's default configuration. If you want to use that field, you need to set the compilation mapping to [%compilation%] .
So, if I change Compilation == %compilation% in the Database tab in iPod Manager and an MP3 has the compilation tag, it will be mapped? I just need to reflect this change in the iPod database? That's what I was trying to do, but need to do more cleanly.

If you have removed the compilation mapping (left it empty), then the component will look at whether the IPOD_COMPILATION field exists for those tracks. So you would need to set IPOD_COMPILATION to 1 or similar for those tracks, and then resync.

As for not being able to see the iPod contents after running Load library, if you post a screenshot of what you can see that might make things a bit clearer.
First things first. I do have the COMPILATION tag set to 1 on all of those MP3s in my media library on my hard drive. Are you saying that the iPod does not look at this, but IPOD_COMPILATION instead? I definitely do NOT have this on any of those tracks.
EDIT: Yep. I added IPOD_COMPILATION tag to both of those albums setting it to 1 on each MP3. They now appear in the iPod under Music>Compilations. If I knew this, I could have saved myself a lot of trouble. So, going forward, I can always add this tag to any album I consider to be a compilation. As far as making changes to mappings and then trying to migrate those changes to the iPod, Whatever I did worked. When I deleted the mapping you quoted, it was reflected on the iPod. I listed everything I did in post 7102. Maybe the "New playlist" command is not needed. Maybe I just need some tweaking? I'll need to tweak some mapping to see if I can repeat what worked before.

Audio Hardware / Re: Buying vintage receivers
Last post by 4season -
Electrolytic capacitors are the bane of vintage electronics, but much depends on how the units were stored over the years. Some of the stuff I encounter looks like it was kept under iffy conditions like unheated garages or storage units, and those may need more restoration work.

Before hooking up speakers I might want to ensure that the receiver is not passing any significant amounts of DC or running abnormally warm, both of which could indicate leaky coupling capacitors. Ditto if controls seem particularly noisy.

In my limited experience, 1970s/80s Technics tend to be neatly done with a minimum of point to point wiring.
