Prototyping session Spring 2020, in the context of Special Issue #12: Radio Implicancies
01
COMMAND-LINE AUDIO
Command line audio workstation
- Listen: Alvin Lucier's I am Sitting in a room
- the materiality of digital audio: samples, sampling rate, sample width, format, channels
- Why does a 8000Hz recording sound different than 44100Hz?
- phonautograph: sonifying non-sound data ...
- commandline audio editing with ffmpeg...
- extracting chunks -- start / duration
- assembling
- bash scripts with loops / variables
- Broadcast audio filtering: compression (as in Dynamic range compression different from audio data compression / "Loudness" and "Normalisation"
- liquidsoap for sound procesing
Exercise: Create an "audio probes" a combination of particular content and a filter that (metaphorically, or literally) resonate
resources:
Question relevant to the special issue: Are we streaming in stereo / mono? At what bitrate... Why does it matter?
02
VOICE
- text to speech / speech synthesis
Specifically the case of [MBROLA](https://github.com/numediart/MBROLA) and the "free" but not "libre" voices. https://github.com/numediart/MBROLA-voices
Espeak + MBrola https://github.com/espeak-ng/espeak-ng/blob/master/docs/mbrola.md
Projects spɛl ænd spik. hellocatfood (antonio roberts) https://www.hellocatfood.com/spell-and-speak/
"real" VOICES http://librivox.org
03
PLAYER
Radio webpage
- Audio player (html/js)
- guest book cgi??!! (socially determined captcha !)
- Player: display metadata (Metadata from icecast? https://stackoverflow.com/questions/6115531/is-it-possible-to-get-icecast-metadata-from-html5-audio-element ) TRY!
- Generate podcast/RSS with json + Template (template.py(python+jinja)/makefile)
- Stream access (scheduling)
(meta/way of working Publishing via git/githook TRY! )
04
BOTS
Cross system / bots (2 parts?)
- infobot
- eliza
- mud/moo
- Bot / chatroom
- Radio stream / schedule
- mediawiki API (pull + push) .. example of epicpedia?
- etherpad API (pull + push?) .. example of etherlamp (make js version?)
