Post-Production

In post-production, spatialization is a precise creative tool. Spacelite can serve for monitoring, creating spatial stems, or upmixing existing content.

Usage Contexts​

Multichannel Monitoring​

Use Spacelite to listen to spatial mixes:

  • Format conversion
  • Compatibility checking
  • Listening on different configurations

Content Creation​

HSR for spatializing sources:

  • Upmixing stereo to multichannel
  • Spatial distribution of stems
  • Positioning effects

Spatial Stems​

Prepare elements for final mix:

  • Music: stereo → 5.1/7.1
  • Ambiences: immersive distribution
  • Effects: precise positioning

DAW Workflow​

Audio Configuration​

Typical routing:

DAW Outputs 1-2 ──► Spacelite In A
DAW Outputs 3-4 ──► Spacelite In B
...
Spacelite Out ──► Audio Interface ──► Monitors

OSC Automation​

From DAW, automate parameters:

# Animated position
Time 0:00  /bus/A/hsr/position -1.0
Time 0:05  /bus/A/hsr/position 0.0
Time 0:10  /bus/A/hsr/position 1.0

Recording Outputs​

Capture spatialized output:

  1. Route Spacelite to DAW inputs
  2. Create multichannel tracks (5.1, 7.1, etc.)
  3. Record in real-time

Format Integration​

Dolby Atmos Preparation​

Spacelite can prepare bed elements:

Stereo source ──► Spacelite (HSR) ──► 7.1 bed for Atmos

Then import into Dolby Atmos Renderer or creation tool.

Multi-Format Export​

Target FormatSpacelite Configuration
5.16 outputs, 80Hz crossover
7.18 outputs
5.1.28 outputs (6 + 2 height)
Stereo (downmix)2 outputs, centered HSR

Compatibility Check​

Test mix on different configurations:

# Test 5.1
/bus/A/output/1-6/active 1
/bus/A/output/7-16/active 0

# Test stereo (fold-down)
/bus/A/output/1-2/active 1
/bus/A/output/3-16/active 0
/bus/A/hsr/width 0.5

Creative Use Cases​

Music Upmixing​

Transform a stereo mix into immersive experience:

# Wide, enveloping configuration
/bus/A/hsr/position 0.0
/bus/A/hsr/width 1.5    # Beyond 1 for surround effect

# Subwoofer for impact
/bus/A/subwoofer/active 1
/bus/A/subwoofer/crossover 60.0

Stems by Family​

Separate sources for different treatment:

Bus A: Rhythm (drums, bass)
  /bus/A/hsr/width 0.6
  /bus/A/subwoofer/active 1

Bus B: Harmonic (guitars, keys)
  /bus/B/hsr/width 1.2
  /bus/B/subwoofer/active 0

Bus C: Vocals
  /bus/C/hsr/width 0.3
  /bus/C/hsr/position 0.0

Bus D: Ambiences
  /bus/D/hsr/width 2.0

Positioning Effects​

Spatial animation for video post:

# Car passing left to right
/bus/A/hsr/position -1.0  # Left
# ... animation over 3 seconds
/bus/A/hsr/position 1.0   # Right

Monitoring Calibration​

Normalized Reference​

For professional post-production:

  • 85 dB SPL (cinema)
  • 79 dB SPL (broadcast)
  • Flat or X-curve target

Procedure​

  1. Calibrate each speaker to target level
  2. Time align
  3. Check frequency response
  4. Document configuration

Project Workflow​

Preparation Phase​

  1. Define target output format
  2. Configure Spacelite accordingly
  3. Calibrate monitoring
  4. Prepare DAW templates

Creation Phase​

  1. Import sources
  2. Configure routing to Spacelite
  3. Work on spatialization
  4. Automate movements

Finalization Phase​

  1. Check on different configurations
  2. Record spatial stems
  3. Export in required formats
  4. Archive configuration

Best Practices​

Consistency​

  • Use same parameters for entire project
  • Document creative choices
  • Save regularly

Compatibility​

  • Always check stereo fold-down
  • Test on headphones (binaural)
  • Plan for reduced configurations
