Thank you for all of your hard work on this nu774.  I really appreciate it.

I think proper video management would require a plugin which does not exist at this time, AFAIK

These quite accurate coefficients are calculated in Octave using MIM (Magnitude Invariance Method). I did these calculations 'bout a year ago.

Then you have this thing, now renamed Chimera:
 https://hydrogenaud.io/index.php/topic,113166.0.html

It kinda makes sense to use fb2k to play what fb2k can tag, but frankly what I miss the most, is a way to auto-tag DVDs.
I have a lot of music DVDs, and I once tried to batch convert to .mkv only to find out that e.g. Discogs is not half as useful - Discogs users enter songs in "human natural song order", and not in chaptermark order, and all for sudden there is something in between or before or be-annoying.

A CDP can not only jump to a particular track mark on a CD, but also to a particular index mark, an ability that somehow got lost during the computer/smartphone audio age.

I was about to write that the ability largely got lost way earlier, as quite a lot of manufacturers dropped the index navigation buttons altogether long before you had smartphones. But OTOH I am not so sure that the "Next" button would then jump to the next track or just the next index point. (My early portable CD player did the latter, but I always assumed that this behaviour was the need to rationalize away buttons in an age when index marks were still a priority, and when the buttons disappeared from stationary players the functionality was gone too. I could very well be/remember wrong.)

I don't know how much indices are still used on the CDs that are manufactured today.

There is some use of index 0 / index 1: that when you skip to track N, it starts on track N index 1 (not 0).  And if you skip from track N-1 to a track that is not N, then you will miss track N index 0. For some live albums (and possibly other albums with continuous sound - that is what the index marks were there for!) you will only hear the artist talk about song N if you keep on playing song N-1 through until it starts on track N index 0. Jump to track N, and it starts at the music; jump from track N-1 to somewhere else, and you will miss the introduction to the song you chose not to hear. Quite a sensible thing to do, as JunkieXL points out.

The standard 2 second silence pregap kinda works that way too: a physical CD player would need a little bit of time to jump from end of track 18 to beginning of track 2 even if preprogrammed to. But in return for that delay, it skips the two seconds of silence that we were used to.

And then there is of course the "hidden track one": music in the pregap before track 1 index 1.
And some geeks even cherish bonuses hidden in pregaps to other songs: http://www.noise11.com/news/will-the-tea-party-perform-the-hidden-transmission-tracks-on-australian-tour-20170620 (disregard the evil connotations of the band's name - just like Isis they chose the name long before the religious nutcases occupied it).

And you have some "novelty use" that is not even music. Arcturus cannot be the only metal band who has indexed track 6 up to index 66 without any other meaning than the obvious ... actually, it is not so "obvious" as using track numbers.


... by the way, hydrogenaudionauts:
How many CDs do you have with narration/music alternating so you could choose play odd / play even / play all? That did not catch much on. I have one such album, by Rick Wakeman.

Thanks so much for the "tag writing feature". I'm glad I won't have to use my "involved" method anymore.
Face it WilB, it's gonna be tricky to find new ideas to improve your script now !

Maybe a nice idea could be to include a allowed genres or (and) forbidden genres... Beyond that, I have no idea what remains to be improved.

The storage capacity and amp are the two key factors in pricing.

A crappy smartphone will have a DAC that works properly.  Even the Apple dongle has a DAC built into it.

Foobar movies manager? Yeah I did that, didn't pursue it any further as I saw no real use in it to warrant further effort.
Made a test layout with columns ui with playlists, playlist viewer, library tree, image brower and infos. Click action in the el playlist launched vlc player via foo_run. This is what it looked like.
Just put all in an mkv container. Foobar can tag the files (the audio part) and they play in vlc without any issue.

Thanks for the added information.  That's actually kind of cool and makes a lot of sense for certain music.

I'm listening to Nirvana's MTV Unplugged In New York album right now and think it would have been useful if they had used it.  There is some chatting and audience interaction after some of the songs that I wouldn't mind skipping or leaving out entirely.
