• Dialog/center extraction: Use mid-channel emphasis and vocal-enhancement filters; suppress side content in center to avoid echoing. Combine spectral gating and source-separation for best results.
• Surround content generation: Use side-channel extraction, reverb tails, and decorrelation. Avoid simply copying stereo sides to surrounds—apply EQ and spatialization to reduce localization conflict.
• LFE creation: Apply low-frequency extraction (below ~120 Hz) from the sum signal, but keep level conservative (typically –10 dB to –6 dB relative to mains, tuned by content).
• Equalization: Match spectral balance across channels; reduce low-mids in surrounds to keep the soundstage clean.
• Delay and phase: Apply subtle delays (5–35 ms) and phase decorrelation on surrounds to simulate distance while avoiding comb filtering in the mains/center.
• Dynamics: Use multiband compression on LFE and overall bus to maintain impact without clipping; maintain headroom for transients.
• Loudness and channel mapping: Ensure compliance with delivery specs (e.g., ±3 dB L/R/LFE balance, target LUFS for broadcast) and correct channel order (ITU/EBU vs. consumer conventions).
