Beginning Audio Series for HPR and OSMP Release

From OSMwiki

ken_fallon and integroll from #oggcastplanet suggested that a lot of OSM content was over the heads of people and there would be value in doing a beginning audio series - a series less focused on how to do X in a program and more to do with the basics of audio and audio recording. This is the planning area for the proposed series.

Ep01 What is sound?:

• A sine wave
• Analog to digital conversion
  • Chopping it up. (Bit rate)
  • How big is each slice. (Bit depth)
  • What is a WAV and what is a broadcast WAV.
  • What is a codec
  • Lossless audio codecs
  • Lossy audio codecs

Ep02 How do you capture sound?

• Errata:
  • Sample rate issues with previous shows.
  • It's called sample rate not bit rate. Bit rate has to do with compression formats.
  • Links for more information on mumble.
    • Info on the new recording feature in mumble.
    • Info on compiling Mumble from source
    • A not very good walk-through on recording mumble output using pulse audio
• How does a microphone work?
  • Condenser
    • Phantom Power
  • Dynamic
  • Ribbon

• What does a microphone pre-amplifier do?

• What types of capture devices you can use?
  • USB
    • v1.0 vs. v2.0
  • PCI
  • FireWire

Ep03 What can we do with captured sound?

Ep04 How do people get my show?
