Audio Rate Conversion
• Converting the sample rate for audio applies only to AES/EBU digital audio. It is not relevant to
analog audio, or Embedded audio. Select OPTIONS->CONFIGURE from the Channel 1
Transport Window. The dialog box in Figure 5 appears.
• Check a box under Audio Rate Conversion only if the corresponding AES/EBU audio source is
not a video-referenced 48K sample rate (as with wild audio or 44.1K audio).
• Click APPLY or OK.
Bit-for-Bit ® Recording & Playback
Dolby®-E, Dolby Digital (AC-3) or other forms of compressed audio require that on playout, the data
stream be identical to the original. Do not use the audio sample rate converters when working with
these encoded audio formats. Further, the Dolby® encoder must be supplied with the same video
reference as the HDSDI input to the server.
Audio Output Sync Reference
The audio sample rate is derived from the selected video sync reference. Audio is recorded at a 48K
sample rate, so the 0.1% pull-down for 59.94 Hz video is taken into account when generating the
sample rate.
