Introduction:

The following provides a brief overview of our standard audio specifications.



Technical Information:

Default File/Output Settings

  • masters: .wav/WAVE at 24-bit/44.1khz
    • note: IASA TC-04 calls for a minimum sampling rate of 48kHz (preferably 96kHz) [1]. We will discontinue use of 44.1kHz sampling rates pending confirmation of appropriate storage space as 24/48 vs 24/44.1 should yield only an 8% increase in space requirements.- arora, 051309
    • note: Our current audio suite [Sound Forge (Sony) | Sound Forge] does not support export/save of the preferred BWF, Broadcast Wave format - arora, 051309
    • typically, 2s of silence is left or created at the beginning of each .wav, with 1s at the end.
    • RMS levels are typically set fairly low, to -25db
  • deliverables: .rm/Real Audio 8 at 16-bit/44.1kHz, 105 kbps (stereo)
    • in the near future, our workflow will allow for some enhancement of the Real Audio files (dynamic range compression, higher RMS levels) in order for delivery of pragmatic derivatives; with the preservation .wav file unaffected by such enhancements.
