   now that i have settled into a kind of (not entirely ideal) workflow, curating a music collection has become a little like knitting: a simple repetitive activity that can fill time.

   for the moment when i pop a cd into the disk drive, the pi mounts it in a way that it looks like a normal drive filled with wav files. i drag and drop them and use strawberry to transcode them. Any linux people have an idea for making this less…. awkward?

   i’ve seen workflows using something called ABCDE but they seem ancient.

   i know flac is popular but i don’t need or want lossless; what’s the best way to do aac compression?

     @zens i’ve used abcde in a basic capacity and had good results for the most part, but i’m not familiar with specific transcoding things— would ffmpeg be able to aac?

     @tychi it definitely can, its quality for some formats isn’t always the best though and i wonder if that is the case for aac or if any aac transcoder is as good as another

     @zens the audio from my camera doesn’t play on web, so i think i need to convert the audio to aac with ffmpeg

     afail ffmpeg is industry standard now so i’m guessing only audiophiles are getting better elsewhere, but that’s flac for audio?

     @zens i used to use cdda2wav but arch wiki says that freedb.org has shut down a few years ago, making the automatic metadata function probably useless. 'asunder' looks good as a gui choice but I've no experience with it, but it lists aac as an output option

     tried asunder. while i appreciate the simplicity of its interface (though it does have some awkward language)

     there’s two problems / annoyances

     1. if a track fails to rip, it only says “1 file failed to be created” and has no options to automatically retry it; you gotta go into the directory to look at which one is missing, then uncheck all the ones that aren’t, and press ripit again

     2. aac transcoding requires a binary that i must compile from source for the raspberry pi.

     the audiophiles say itunes 96kbps is the best aac encoder; they have elaborate workarounds in which they extract the dll from the free quicktime install.exe and wrap a front end around it.

     this doesn’t seem possible on a raspberry pi

     @zens looking at ffmpeg again

     libopus

     that looks like the default is 96kbps, which might get you the quality without the hacks

     i found that on this page by looking for 96kbps to do a reverse lookup for possible transcoder? codec? what’s the technical term of the thing we’re talking about?

     @tychi quality to bitrate is not the sole consideration. the reason i am making so much effort to figure out the best way to get aac is my primary listening devices are apple devices. there’s really not that much point transcoding to opus if the navidrome software is going to quietly transcode it to mp3 or aac anyway

     @zens yeah, transcoding and ffmpeg are entirely new to me.

     for workaround, would it be possible to run an old mac as a server and make a request to it from the pi to do the transcoding or would that defeat the intention of the pi?

     @tychi ideally we have as few electricty suckers on at all times at possible. since my last reply i found the opus story a little more complicated; My old as fuck iphone does support playing opus but only inside apple’s proprietary “caf” container.

     I am not sure how to make use of this information for navidrome’s settings or base formats, i just want to avoid making it transcode stuff as much as possible

     @tychi at least this one client app, substreamer, seems to prefer transcoding and caching in mp3 format which seems… a bit outdated an approach

     @tychi also surprising to me is native support for flac. Had no idea iphones did flac

     @zens i can see that as a potential needed to be implemented to get top label producers on board with itunes— it’d be hard to take a music platform seriously that couldn’t cater to the *philes

     a decade or two ago, I ripped my entire CD collection to ogg vorbis using a program named grip, that used ffmpeg underneath
     
     now I regret not having ripped to flac or somesuch. if I had, I could reencode to other formats without quality loss.

     @lxo i think i will do flac then. my immediate issue is i am running out of space on my 32gb microsd card but this is a cheaply solvable problem. i also have a 500gb external spinning disk for backups so i can keep the flac there and the shrinky files on the card

     @zens Sorry, we only got GNU people here.
     
     The easiest way to automate that would be GNU find.
     
     Something like; find path/to/cd -iname "*.wav" -exec ffmpeg -i {} -map_metadata 0 -c:a libopus {}.opus \;
     
     Too bad that will leave the .wav extension.
     
     
     You could also use a modified version of a GNU bash script from my GNU/Bro, adjusted to include metadata from the CDs.
