The Multichannel Downmix Integrity Challenge: EQ, Phase Coherence, and the 7.1.4 → 2.0 Collapse

The goal of an immersive mix in a high-channel count format like Dolby Atmos (e.g., 7.1.4) is to create a captivating sonic world. However, the true test of engineering skill lies in ensuring that this dense, spatial soundfield translates seamlessly when mathematically reduced, or “folded”, to 5.1 and finally to stereo (2.0). When individual channel processingContinue reading “The Multichannel Downmix Integrity Challenge: EQ, Phase Coherence, and the 7.1.4 → 2.0 Collapse”
