       | This is fantastic. I've got two samplers that I've just started
       | building a sample library for (Korg Drumlogue and Teenage
       | Engineering's KO II) This is exactly the kind of tool that will
       | help me find interesting sounds. Great job.

         | Even better, while there's plenty of music to be had, there's a
         | lot of other stuff as well. In my case, what led me to even
         | find this was just looking for public domain audio files I
         | could use for testing and debugging various bits of audio
         | processing software that I'm working with.
         | 
         | I'll be interested in maybe using some files for testing speech
         | recognition and what-not as part of that. So some of the
         | interviews and spoken word recordings will be of primary
         | interest to me.
         | 
         | That said, I'm sure there's some interesting music mixed in
         | here as well and I'm looking forward to exploring that. :-)

       | Love it that they didn't only chop everything, analyzed it and
       | offered people to download single items, but put a sequencer
       | there as well as offering bulk downloads (basically sample
       | packs). That you can filter by note + pitch is awesome too! Will
       | be fun to play around with.
       | 
       | I'd love to have a volume slider though, because it does get a
       | bit loud when dragging the mouse, so I don't have to turn down
       | everything. Or even better, if every clip was also adjusted by
       | perceived loudness (with a on/off toggle).
       | 
       | Edit: The following "end-of-residency retrospective" article was
       | excellent too: https://citizen-dj.labs.loc.gov/retro/

       | This is very, very cool. I've always wanted to use federal
       | recordings, and this makes it really easy. I wonder how developed
       | the filters are.

         | Seems the filters are automatically taken from the Library of
         | Congress items themselves, and in the case of "Jews", there is
         | only a single item that matches that filter:
         | https://www.loc.gov/item/00694076/ ("Cohen on his honeymoon")
         | 
         | There is a bunch of other filters that doesn't make much sense
         | is a musical context, like "facial expressions" or "dough" but
         | again, those come from the Library of Congress, not from
         | CitizenDJ, it seems at least.

         | Creator here. Yes, I confirm that those terms are taken
         | directly from the Library's subject headings:
         | https://en.wikipedia.org/wiki/Library_of_Congress_Subject_He...
         | . And yes, the Library's subject headings, and really the
         | broader practice of describing cultural/historical materials,
         | are sometimes problematic and constantly evolving.

       | This is a very cool tool. Remind's me of Peez's beats from Very
       | Bad Wizards.

       | Excellent!
       | 
       | Is there an explanation of how the 4 samples are chosen in remix
       | mode and is there a way to change them individually?
        
         | beefoo wrote:
         | Creator here. In general, the samples are automatically
         | selected using a mix of onset detection and audio analysis,
         | giving preference to clips that have a clear musical pitch. I
         | give a brief explanation here: https://citizen-
         | dj.labs.loc.gov/about/#how-do-you-selectcrea... . The sequencer
         | randomly selects 4 of those samples that are sequential in the
         | source audio. You can change them individually by clicking on
         | the track settings button (the mixer icon).

       | My only qualm is in "browse" mode, I wish the clips were slightly
       | longer. Or that holding down the mouse/trackpad kept playing the
       | clip. As of now, and unless I'm doing it wrong, the clips are so
       | short you only get the vaguest sense of their content.
       | 
       | That aside, really great work.

         | Their processing splits out individual sounds from longer
         | clips, so the purpose is to browse those clips, not the full
         | songs/recordings. Works quite well when you're hunting for
         | things to use as samples in music production.
         | 
         | But regardless of that, once you've selected a clip, you can
         | click "Play in context" to playback the sound together with
         | what's before and after. And for the full song/recording, you
         | can press "View on loc.gov" to play the entire thing.
