Elmo Weber's work on Wim Wenders' acclaimed 1999 documentary Buena Vista Social Club represents a historic, pioneering milestone in cinema audio post-production. Weber served as the supervising sound editor and re-recording editor for the film.

He achieved a cinematic first by mixing a major, theatrically released feature film completely "in the box" (ITB) utilizing Digidesign's (now Avid) Pro Tools.

At the turn of the millennium, this approach challenged the entire infrastructure of Hollywood's traditional re-recording stages.

The Technological Landscape of the Late 1990’s

In the late 1990s, Pro Tools was universally accepted as a tool for editing dialogue, sound effects, and music. However, actually mixing a feature film still relied strictly on massive, million-dollar analog or early digital physical mixing consoles (such as SSL, Neve, or Harrison).

"In the box" mixing—processing all volume automation, panning, EQ, and dynamics entirely within the computer's CPU and DSP cards—was widely dismissed by high-end film mixers.

Skeptics believed the digital summing engines of the era lacked the headroom and sonic warmth required for a theatrical release, especially for a music-centric film.
