Loudness processing benefits
 
Production | AV | Multimedia | Editing | Game Audio
  • Prevent loudness jumps between sections
  • Match audio sources for loudess consistency
  • Rapidly achieve loudness balancing across differeing material
  • Maintain dialogue clarity
  • Check and balance music and FX
  • Rapidly prepare libraries for loudness matched
  • Easily match material with differing dynamic range
  • Edit rapidly, maintaining loudness profiles
  • Produce with increased dynamic range impact
  • Measure and targed dynamic range for playback system
  • Optimise for minimum codec and DA distortion
  • Deliver to loudness specification automatically

Post Production | Broadcast
  • Meet delivery specifications
  • Comply with legal requirements
  • Increase audio quality
  • Save time
  • Spot edit rapidly, avoiding loudenss jumps
  • Harmonise program|channel|station content
  • Optimise for differing transmission codecs
 
Typcial Applications
 
QA and compliance
  • Verify out-sourced material
  • Meet loudness delivery specifications
  • Streamline in-house editing
