Notes from Sudo Radio session at 1st annual State of the Room Unconference 12/8/12:

marina: some audio production
max: a quick learner!
len: interested in organizing
mark b: sf liberation radio news show, enemy combatant radio (online). news and interviews. if we have a transmitter, would be good to do live radio and record it. live radio is easier because it takes less time to produce (don't have to edit). experienced with tech.: can host streams, build transmitters, has set of modules for drupal that allows you to list schedule of shows and it records the stream during those timeslots.
august: "Camp caster" (broadcasting solution). experience with prod & tech, used to do weekly show in austria (focused on art radio), wrote multi user streaming engine, works with pure data, (userradio: reads all kinds of audio content. lets people upload things to the server in any format; no need to convert format. lets people make a live radio show together online. when you raise channel 1, everyone sees channel 1 raised.)
jae: interested in connecting spaces together (sudoroom with creative spaces) in audio and video. would be good to share time of the day with multiple spaces. also youth radio is nearby, many places that do audio are in our community. they are resources.
ajay: not much experience, interested in community.
ryanj: loves music, wants to allow a lot of ppl to contribute playlists/audio/music content, wants to have a web interface to coordinate scheduling and playlist creation. "diy kit for setting up your own radio - hardware and software"
rusty: experience with audio for film, records in studios, web work for studios, works with ccrm, open source multi track editing program, knows how to record, mix, work mics, operate equipment.
garrett: radio show in college, was a recording and studio engineer at oberlin, fundraiser where people gave away radios just tuned to their radio station. this would be fun to build!

3 components to move forward:

  • 1) infrastructure - building the space itself, ensuring that we have all the necessary equipment
  • 2) distribution - livestream or broadcast? folks are interested in setting up livestream first
  • 3) content - determining what kind of content everyone is interested in producing, how many hours per day we'd like to be online, etc.

equipment needs:

  • server (CHECK)
  • analog to digital conversion
  • pre emp mic (2)
  • 2 pc's
  • soundproofing (CHECK?)
  • reflections ($99) sm57's
  • 2 xlr cables (CHECK)
  • 2 headphones

legal issues: internet radio: to play licensed content, typically radio stations make a deal with radio content distributors. they want a lot of data on what you play. if one doesn't commercialize and has perhaps only a hundred listeners, there is a chance that practically this won't be an issue.

odds and ends:

  • sudo radio 2.0 - wants to generate digital audio. interested in one night generating audio :) supercollider. can build synthesizers. can build mics. can build speakers. build headphones.
  • transmitter on the roof, transmitter here with antenna going onto the roof? connectivity from here to the roof?
