Ahmed GelbyDirector
Ahmed Gelby is a systems-focused audio engineer and technical consultant working at the intersection of post-production workflows and large-scale media infrastructure.
His work examines how contemporary audio practice breaks down when mixes are expected to translate across heterogeneous playback contexts — from calibrated control rooms to uncontrolled consumer environments.
Drawing on fieldwork in post-production and broadcast-scale deployments, Ahmed has instrumented and validated the limits of ‘one-mix-fits-all’ assumptions, showing how translation failures emerge not from creative intent but from architectural and workflow constraints upstream.
His recent work focuses on probing these failures through measurement, controlled experimentation, and prototype systems that shift adaptation from the mix stage to playout.
Ahmed is Director at Flicktronix and previously worked as a Senior Design Consultant at Audinate, supporting large media organizations including Warner Bros. Discovery. His work is concerned with aligning audio decision-making with real listening conditions, rather than idealized ones.
Mixing for Streaming and TV: One Size Does Not Fit All
Dialogue translation routinely fails once cinematic mixes leave the controlled monitoring environment. Not because of creative error, but because post-production workflows assume a stable listener, device, and acoustic context that no longer exists.
This work examines how that assumption breaks down across domestic and mobile consumption scenarios, where mixers have no visibility of downstream playback conditions. Based on behavioural data from 500 listeners, interviews with professional mixers, and a series of controlled experiments, this study evaluates whether translation can be improved by shifting adaptation from the mix stage to the playout stage.
A prototype system was developed that dynamically adjusts the mix at playout based on known listener context, device characteristics, and environment, without altering the original creative intent. The results suggest that translation failures are better addressed through context-aware playout architectures than through additional mix variants or tighter standards, reframing where responsibility for translation should sit in modern audio delivery chains.
