  • The following information is applicable to all computing platforms
  • The best quality for saving digital audio recordings is a lossless format
  • A lossless digital format retains all the data that was captured during recording

Save audio recordings in  WAV  format

For transferring audio files across the Internet, use  FLAC  format.
(FLAC = zip for audio players and editors)

Caveat For MAC GarageBand Users

– Does not easily export WAV via Share

Share exports lossy formats (i.e., OGG, MP3)

When you are capturing a deep humming noise distortion in the microphone, there are some things that you will want to look at to avoid the aforementioned issue.

  1. keep your headset away from magnets (i.e., speakers), electrical wiring, and kitchen appliances (i.e., microwaves).
  2. Use a USB headset.  (I use is a Plantronics Audio 655 DSP with built-in noise reduction)
  3. HUM can be cleaned up slightly with audio restoration plugins (i.e., Audacity noise removal).
  4. Ground looping
  5. Having the microphone volume too high will cause feedback and distortion.

Rule 1: the best output depends on the best input

This podcast includes ‘soft’ subtitle in English that can be viewed in Quicktime.

Dr. Bob Barnetson Course Introduction for Labour Relations

This video was created with:

  • Sanyo VPC-HD2000A with external stereo microphone
  • Lastolite background
  • Adobe CS 5.5 Premier and Audition
  • iMac
  • Jubler subtitler
  • iSubtitle  (merges subtitles into video file)
  • Subler, MetaX applications (for creating/modifying metadata)

Future considerations:

  • use external mono microphone
  • experiment with teleprompter

Some experiences:

  • Professor course into podcasts are longer than a human introduction
  • A script is critical to keeping the conversation on track but does not match perfectly with the recording and thus requires further transcription (merging script with actual output to obtain accurate subtitle)
