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). 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. Projects already underway at the 24/44.1 spec will maintain that specification. - arora, 062910. Update: given remaining storage concerns, we will continue with 24/44.1. - arora, 030911.
    • 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
