Writing for the Ear

CODECs and compression

  • ‘coder-decoder’
  • Definition (wikipedia)
  • The difference between lossless & lossy?
  • File Types:
    • MP3 (MPEG-1, audio layer 3 – MPEG = Moving Picture Experts Group)
    • AAC (advanced audio coding – MPEG-2, part 7 and MPEG-4, part 3)
  • Trade off between file size and quality
    • Average bit rate (data/sec)
    • MP3 – 128 kbit/s transfers or 128,000 bits/second (lower bit rate, lower quality)

Practicing With Audacity

Download and install Audacity on your laptop or use a lab machine

  • Why Audacity?
    • Open-Source, X-Platform, Free, Multi-Language Support
    • Record audio to single tracks
    • Multi-track editing/mixing
    • Output to .wav (native) or .mp3 (with add-on)
  • Not going over audio input tonight, just editing!

Audio Samples
With Windows, you can use Sound Recorder to capture any audio playing on your computer. Ditto Garage Band for the Mac.There are many web sites that offer audio with creative commons licenses (restricted use) as well as royalty-free compilation CDs and free royalty-free music. Some of these web sites require a small fee for use.

Sound Effects

Recording Audio
There are many tools for creating and recording samples for your podcast. Hardware, such as computers, digital audio recorders, turntables, CD, DVD and Mp3 players, and microphones can be borrowed from the Communication Department, but your mobile phones, PDAs or laptops may have all the recording capacity you need.
