Surround Calibration Audio Files

The Apollo X Surround Sound chapter within the Apollo Software Manual - Thunderbolt.pdf includes a surround monitor calibration procedure. This procedure uses calibrated digital audio source files that are played from within a surround-capable DAW while volume is measured with an external SPL meter.

The audio files referenced in the monitor calibration procedure can be downloaded by clicking the link below. The download includes two mono files at 48 kHz:

  • 500-2500 Hz pink noise @ -20 dBFS.wav
  • 40-80 Hz pink noise @ -20 dBFS.wav
