+# Transcript
+
+Hello, my name is Grant Shangreaux. This is my talk titled Bard
+Bivou(m)acs: Publishing Music with Emacs. I'm a software developer
+with Unabridged Software in Lincoln, Nebraska. Long time Emacs user,
+relatively new Emacs hacker. Hopefully, I'll be able to show you my
+workflow, with how I publish music with Emacs. All right. 
+
+(00:30) So as a musician, I would like to publish my music online. I could
+publish with popular online music services, but I'm more of a
+DIY-type, so I chose to go ahead and publish with Emacs. What's the
+motivation behind this? A lot of it comes down to some fundamental
+freedoms that Emacs and GNU software represent to me, as well as my
+ideas on culture and my background. I don't believe that music is a
+consumer good. It's a form of knowledge, like an algorithm. And it's
+just such a part of culture, like in tribal cultures, music was seen
+as a gift from the cosmos or the gods. It was a gift maybe through an
+individual vessel, but was shared with the people and shared with
+everyone, kept alive by the culture itself. So to me, music is
+something that should be shared and should be freely enjoyed by
+everyone. Of course, artists should be compensated as well, but that's
+a whole different topic. 
+
+(01:39) So when I want to share my music, I want to do it without
+impacting anyone's freedom. Using GNU software like Emacs is a good
+way that I can ensure that I won't be requiring people to sign away
+their freedoms for anything. There's a lot more I could say about this
+but I don't have time. Feel free to reach out to me by email or IRC.
+Part of the motivation for me, personally, is that Emacs is super
+magical. It's an all-in-one solution. Like I said, the GNU software
+aligns with Creative Commons' ideas. I can do file management. I can
+author HTML, all the web stuff I need even, literate-style. I can
+handle media and metadata. I've got version control, remote server
+access... All the tools I need are right under my fingertips with this
+tool that I use every day for a long time. I don't need to look
+elsewhere. 
+
+(02:31) It was a challenge. I wanted to see if I could do this all
+within Emacs itself. So, how do you use Emacs to publish music? Well,
+for me, I needed a couple of things. I needed to be able to audition
+and label unlabeled audio tracks. I have a lot of files that I don't
+know where they came from. I don't know what they are. I need to be
+able to listen to them, and I need to be able to add metadata to
+whatever audio format it is and rename the files based on that
+metadata, potentially. And in the end, I wanted to take those files
+and programmatically produce a web page for people to consume. 
+
+(03:08) I found out that Emacs scores a hundred percent on all of
+these requirements that I had for this, and a lot of that came from
+EMMS, the Emacs multimedia system. EMMS is great. If you haven't
+checked it out, please do. It's a little bit unintuitive, but once you
+get into it, you know it works. Basically, what EMMS gave me was the
+ability to listen to the tracks, organize playlists. On top of that,
+it gave me super-powered metadata authoring. 
+
+(03:42) I'm going to demonstrate that to you. So in order to do this,
+you have to require markable playlists, so (require 'emms-mark). I'm
+going to go through, and I'm going to open the red... I've got this.
+These files here. So you can see these files are mp3s. They're
+recorded on a digital recorder. If I had the choice, I would have a
+recorder that used a different format, but so be it. I can mark all
+these files and I can do EMMS add to .., and now they've been loaded
+into a playlist. So you can see the playlist here. There's some
+leftover files. 
+
+(04:30) So I've got these three files in my playlist, and as
+you can see, it's just the file name, the path. I don't have any
+metadata associated with them. In this playlist, I can hit E, and
+it'll bring up a buffer showing the tag information that I have. I
+could edit these here. I could edit them one at a time, but that's not
+really great. I want superpower metadata authoring. So, by marking
+them, I can then hit E, and I have all three of the tracks loaded up
+in this tags buffer. On top of that, I can do EMMS tag editor, set
+all, C-c C-r, and I want to set the artist. so these are some
+recordings of my family. So, Shangreaux, set all three of them. I want
+to set the album: Spring Walk with Lap Harp. I want to set the year.
+And then I'm going to go ahead and put these in manually, but with the
+power of Emacs keyboard macros and registers and so on. I could do
+this programmatically as well, which would make it a lot easier if I
+had much more than three files to do this with. Submit the changes
+with C-c C-c, and now we've got the playlist. You can see the artist
+and track number have been updated here. 
+
+(6:15) And then the final piece of this is that if you look at this,
+you can see that the file name is still the same. So if I were looking
+at the directory, I would still have this file name. When packaging
+these up for a release, for people to download, it's nice to be able
+to have that filename reflect the track number and the artist and so
+on. So there's another command, EMMS rename tag editor, rename, so it
+could be just capital R. I think I need to mark all of these, hit
+capital R, and then it's going to ask me to confirm and say yes to all
+of them. And now, if you look in the-- whoops I have to update
+it--you'll see it's been updated with the artist, track number and
+track name. This format is a format string, so it's customizable of
+course. I just decided to go with the default. 
+
+(7:21) So that's pretty great, this workflow just with EMMS. I didn't
+have to do anything. This is all there. It's all built in. It gave me
+exactly what I was looking for in terms of being able to process a lot
+of raw audio files add metadata to them and get them ready for
+publishing. And this is for publishing for playback in any media
+player. It'll be useful. Not just for the web page that I'm building.
+
+(7:48) So the final part, of course, is to build the web page. Emacs
+makes authoring HTML trivial. As I was going through this, I wanted to
+challenge myself and just be, like, can I do this just all with Emacs?
+Can I just make this? I don't need a... I don't need Ruby. I don't
+need Rails. I don't need Node. I don't need any of this other stuff. I
+have my tool right here. It's a fully... It's a whole operating
+system, basically, plus programming languages. So the first thing I
+started with was buffer scripting for manipulating text. That's kind
+of the easiest way to do it. Basically, anything you can do in a
+buffer, you can do programmatically with Elisp. So this might be a
+good example for beginners. If you haven't done any Elisp yet, a
+simple example is to create this this div output here. You can use
+this with-temp-buffer, so basically creating an imaginary buffer.
+insert is just like typing, so you put strings in, you put new lines
+in, you can build some strings together. Here you can see I'm doing a
+random number, so every time I execute this, my content change. I
+can generate dynamic content in HTML blocks with Elisp. 
+
+(9:04) For my web page builder, It's a little more complex. I'm
+pulling data out using EMMS data structures, so it's pulling that out
+from the track data. And then I'm using some program to generate list
+elements, so each track is going to have the title and track number,
+and then a button for playing it, plus the source of the audio file,
+which will get added here. Right now, this is hard coded for Opus, so
+it won't work for my MP3s. I'm going to skip over snippets. Turns out
+format strings were good enough for me. Snippets could be useful, but
+format is super powerful, and I didn't really even need all that much
+power, basically, just doing string interpolation. So if you haven't
+seen format before, you basically put these control strings or control
+characters inside of a string, and you can generate an output string
+that you want. So in my generator code, basically, it's down here, I'm
+calling format with this Bard Bivou(m)acs template, and that's
+basically a big a big string of HTML. It's just my whole page of HTML
+with those control characters in just four places. One of them
+populates the track list. That's really the meat of the program.
+Again, this is a combination of using buffer scripting, using HTML
+mode, inserting text format strings, and then I can indent-region so
+the HTML actually looks pretty when it comes out of it as well. I will
+show that, just really quick actually. So you can see, this is the
+HTML that got generated. I've got my template. I inserted the title
+here, the style, the font was all inserted, and then this whole list
+of of tracks here. It's kind of messy to look at, but this track list,
+this whole div here, is all generated by my generator code, and it
+works. It's great. Okay, moving on. 
+
+(11:27) So the other thing was that as I was developing this, I
+decided to use Org Babel and some of his its features for
+multi-language things because I needed to style it with CSS and and
+put actions in Javascript, and also I used SVG for authoring stuff. It
+was a little bit complicated. It probably would have been simpler had
+I not used Org Babel, but it's also really fun. I think it's a cool,
+cool idea to use literate programming. My idea was to create HTML
+components. I could name it like this, put a format string inside it,
+and build a function in Elisp to format it and spit out the HTML that
+I want. By doing this, then, I can just change things in my Org file
+which, not getting a whole lot of time to work on it, I can come back
+to it and I have a lot of notes. I can kind of generate things as I'm
+going and keep notes for myself, and keep the... I don't know. It's
+cool. Literate programming is fun. So I don't need to go into that too
+much, but you can see if I execute this here, I get the the div that I
+want. It's a little bit funny. You'll see I have the string like this,
+the way that noweb expands, I can't do this on a single line. It looks
+funny when you do that, so that might be something to work out later.
+CSS blocks can either be tangled out and referenced in the HTML source
+or inlined. Here's an example I have of inlining it. So I've got my
+little CSS block named style, Javascript named script, and then I've
+got this HTML source block with noweb expansion. These double angle
+brackets here are where I'm going to expand the block named style. I'm
+actually calling a function, so I want the result of the function
+here, and then the script will just get expanded here. So
+org-babel-expand-src-block, you can see what it looks like. I've got
+my style here. I've got my title. I've got that main content class I
+showed before, and the script as well. So that's kind of cool. I could
+just run org-babel-tangle and get my thing out and just edit one file
+instead of multiple files. Not for everyone, but I thought it was kind
+of fun. All right. 
+
+(13:45) Oh, and the final thing is that in Emacs, you can author and
+view SVG. So this is just an Org. This SVG, I used to make the play
+and pause buttons. I didn't know this, but if you edit an SVG file,
+you can toggle back and forth between the code and the image. It's
+pretty sweet. So I can iteratively work through this because of how
+Emacs is. 
+
+(14:20) Final considerations here, like when doing this, I want it to
+be all free, so I want to use fonts that use a free license. I found
+GNU Unifont. It's kind of cool. The content license... I chose
+Creative Commons Attribution ShareAlike, which is kind of like the
+GPL. Ideally, I could serve it with Emacs. I'd like to remove
+idiosyncrasy so other people can use it. It's pretty much just my tool
+right now. Not requiring the web browser... I can ship playlists so
+that you can just click or link to a playlist on your favorite player,
+even EMMS if you want, and then packing up those albums in like a ZIP
+or .tar file. 
+
+(15:04) So you can go to churls.world . It just has a link to this
+album. I'll display it here in just a second. You can contact me. I'm
+shoshin on #emacs in IRC and on sourcehut. You can email me
+grant@churls.world, personal, or grant@unabridgedsoftware.com. All
+right, now. Let's see about this... This is up online, so if you want
+to listen to my college band's album from 20 years ago, here it is:
+Cassiopeia Basement Days. Whoops. I made this art in Krita. You can
+press play. You can skip around. I do have the playlist up here too.
+So yeah, thanks for listening. I hope you enjoyed it, and enjoy the
+rest of EmacsConf. Goodbye!

+# Transcript: Q&A
+
+So first question, what does Bard Bivou(m)acs mean? Good question. In
+one version of my talk, I spent too long explaining it, and decided to
+cut it out. It's basically a bad pun on band camp. A bivouac--I don't
+even know if I'm pronouncing that correctly--it's like a tent or a
+camp that you put up hastily, and a bard is a musician, of course.
+Yeah, I don't know. I like puns. I'm a dad. That's the best I could
+come up with. I'll probably find a different name for it but I liked
+that "bivoaucs," if you stick an m in there, it becomes Bivou(m)acs.
+It's kind of like editor macros for generating some HTML. Yes, it is
+confusing, chatting on IRC at the same time. Great question. (Amin:
+Grant, so right now, you're sharing your screen. Are you planning on
+showing something with it, or for example, should I maximize you?) I
+don't know. I can turn it off for now. Okay. (Amin: You can turn on
+the webcam.) Yeah, okay. (Amin: I'll maximize your webcam.) Okay,
+thanks. I'll get to the answer for my color theme here in a bit in
+IRC. 
+
+(1:31) Next question on the Etherpad, does this metadata workflow also
+support unsynchronized lyrics within ID3 tags, multi-line metadata? I
+don't know, actually. It's funny because I was trying out different
+things with metadata, and really the biggest thing was to figure out
+how to do mass tag editing. And that was like... It wasn't very
+intuitive, like I said, with EMMS. I think EMMS is really great, but
+its interface is huge. like if you do M-x and type emms, you get I
+don't know, 270-some candidates. There's a lot of functions going on.
+I basically found the features that I needed to get this workflow
+working. I would guess that you probably can do it, and if you don't,
+if you can't do it out of the box, I think you could script EMMS to do
+that. I'd like to know more, and I'm certainly going to be
+investigating it. I will try and post my findings somewhere online. 
+
+(2:39) Is it possible to import batch metadata? I'm not sure. I would
+guess yes is the answer. EMMS can connect to metadata services. I
+haven't done that because I was just using audio files that I created
+myself. I know that on the back end, it calls out to shell programs
+for tagging things. there's a lot of different options that can shell
+out too. I was using the the vorbis tools to tag the particular files
+I was working with. You can also use tiny tag, and there's some
+other... That might be the python library. I can't remember. There's
+two other libraries that I can shell out to for doing metadata. 
+
+(3:24) My current workflow for tagging music is to first apply replay
+gain in fubar 2000, fix egregious mistakes, use beats to apply
+metadata from music brains, or discogs, go over remaining albums with
+fubar 2000 again. Is there a chance textual tagging could allow doing
+it all in one program? Have I experimented with mass tag update
+queries? I have not. Again, I was just doing this workflow, taking raw
+files with no tags and doing that. I believe because it calls out to
+the programs in the back end, I'm sure you could work that out. I
+think EMMS would benefit from having something like that because we
+work with text, and being able to use Emacs as a front end for those
+updates would be really fantastic. So really, it's just a matter of
+writing the interface to the external tool. 
+
+(4:22) Is there a link to some info expanding philosophy of how to
+compensate musicians? No, I don't really have a lot of philosophy
+around that. I guess the first thing I could say would be something
+like a universal income. I feel like that would solve a lot of
+problems, if musicians could just be musicians and not have to worry
+about their pay. I will think about it more. This is one of my first
+forays into getting public with some of these ideas, so I will try to
+do more and let the community know. 
+
+(4:54) What Emacs theme am I using? Can't remember. It's one of the
+Kaolin themes. I think it was Aurora or or Bubble Gum, maybe, but the
+Kaolin themes are nice. I recommend them. Not using Doom Emacs, Doom
+mode line though. It's very pretty.
+
+(5:17) SVG support built into Emacs? I'm using Emacs 27.1, and yes,
+SVG support is built in. I may have had to compile it with some Cairo
+support. I don't remember for sure. But yes, you can even take
+screenshots of your Emacs from within Emacs in SVG. It's pretty great.
+I don't know how much more time we have left for questions. That's
+most of the things on the etherpad. (Amin: I think we have like 10
+more minutes to catch up with the schedule. If there are more
+questions, feel free to answer them.) I'll start looking through IRC.
+(Amin: And keep an eye on the pad too.) Thank you all for listening
+and for enjoying the talk. I'm glad it turned out well. Awesome. Yeah,
+it's been fun so far. How did I manage? I can post a snippet of that,
+or actually I can share my screen, can't I... Okay. I actually have it
+up right here. 
+
+(6:49) So I think I got this from alphapapa, to be honest. I define
+screenshot-svg. It's an interactive command. Oh yeah, there's
+alphae.papa Okay, there we go. I would like to change this so that I
+can get it into the copy-paste buffer so I don't have to copy the file
+in, but I haven't really hacked on it yet. 
+
+(7:20) Okay, org heading colors. That might be a good question. I know, the
+presentation... Sorry, it's hard to think and type at the same time.
+Think and talk and type. 
+
+(7:41) So the presentation is just a normal org file, right, so I have my
+headers, and the author--you can even stick your email and other
+headers in there. But there's a package called org-tree-slide. Whoops,
+why is it not... I must have not required it. Good question. (Amin:
+Grant, can you try sharing your screen maybe?) Oh, is it not shared?
+I'm sorry. (Amin: Thank you.) There we go, should be coming up. (Amin:
+It's coming up. Yep, we see it.) Awesome. All right. Okay. I don't
+know why this isn't working. It was working. Okay, you want to see the
+screenshot. Whoops. Okay, I just took a screenshot. So, org-tree-slide.
+I don't know why it's not launching. I thought that I had required it,
+but I must not have. Maybe I'll try. Okay. So there we go. So
+org-tree-slide is a way that basically uses narrowing and some kind of
+font tricks to... it changes your titles or your metadata into this
+banner for the title here, and it automatically sets the faces for
+you. You can customize that, of course. And then, as you go through
+the Org file, you get these kind of nice animations and-- what's it
+called--breadcrumbs up at the top. So org-tree-slide. I highly
+recommend it. It's really nice because you can give your presentation
+and practice it, and while you're practicing it, you can edit things
+as well, because it's still just an Org document using narrowing, you
+know. It doesn't actually change anything. Definitely recommend
+org-tree-slide mode. Okay, let's see, what else... 
+
+(10:29) Share my screen to demo. Oh, that's the SVG. Let's see. Okay, so I
+don't know if you can see this now, but I'm actually viewing the SVG
+screenshot that I took with Emacs. See here's the source of it. So
+Emacs made that. And here's the image. It's cool because you can even
+do it again and again, and open more screenshots of screenshots. Yeah,
+definitely Emacsception. Fun stuff. Anything else in chat? Heading
+colors? Oh, yeah. I talked about the themes. This is another Kaolin
+theme. I think the one in the talk was maybe this one, Aurora. Oh,
+here, there's something funny when you start org-tree-slide with a
+different theme. This top header bar gets the faces from that previous
+theme. I have not figured out how to fix that yet. Did I have to
+compile to get the screenshot? I think maybe I did. Yes, if I'm
+remembering correctly. I got Emacs 27. I'm not on a Mac. I saw
+alphapapa's comment on reddit, and then I recompiled it with Cairo
+support. Yes. 
+
+(12:18) Okay, lots of good conversation on here. Yep, I have like one or two
+more minutes. Okay I guess while I'm here, I might as well say thank
+you to the organizers. I really appreciate everybody's work on this.
+It's fun to be a part of this community. I'm enjoying the other talks
+I've seen so far today, and I'm looking forward to to the rest. It's
+really interesting, just from being on Emacs in IRC for a few months,
+I've already connected with a lot of interesting people and have a lot
+of cool connections already. (Amin: Thank you for being a part of the
+community, Grant.) That's good to be here. I have another talk
+tomorrow as well. Oh, thanks for everyone in the Etherpad for putting
+more comments on these questions here and taking the notes. (Amin: I
+think that's about all the time that we have for the Q&A. Okay. Thank
+you again so much, Grant, for your awesome talk and for popping in for
+questions.) Yeah, thanks again for hosting. See you later. Cheers!
