The Symphony of AI: How It’s Rewriting the Rules of Audio Post-Production

The Analog Days: A Reverence for Reels

Tape recorders, those titans of tech nostalgia, have long been cherished for their tangible nature—each reel a physical embodiment of sound. Yet, despite their charm, they carried the burden of cumbersome editing processes. The task of cutting tape and transferring sound for edits and mixes, especially for spoken content, was a meticulous and daunting challenge.

The Digital Leap: DAWs in the Spotlight

Then came Digital Audio Workstations (DAWs), revolutionizing audio post-production with their powerful, non-linear editing systems. The digital realm allowed for an editing ease that analog could never match, where a mile of splicing tape became a few clicks of a mouse. DAWs empowered audio professionals with Digital Signal Processing (DSP), facilitating a myriad of effects and perfect copies, all while significantly reducing the manual labor of editing.

AI: The Composer of Clarity

Yet, even with DAWs’ prowess, certain audio alchemies remained just out of reach—until AI entered the studio. AI’s ability to ‘imagine’ and reconstruct the missing pieces of audio puzzles has begun to transform the post-production landscape.

Take, for instance, the new Beatles’ song Now and Then, the Technology developed for this song allowed dialogue editor Emile de la Rey to resurrect John Lennon’s voice from a low-quality cassette, laying the groundwork for a track that McCartney refers to as the last Beatles record. AI didn’t just clean up Lennon’s voice; it purified it, enabling McCartney to blend it seamlessly with new recordings.

McCartney’s use of AI didn’t stop there. During his tour, he was able to perform a virtual duet with Lennon, a feat made possible by AI’s sophisticated audio separation techniques. And while AI has powered the creation of some «deepfake» vocals in the industry, McCartney assures that Lennon’s posthumous duets are purely the result of AI’s extraordinary capacity to clean and separate existing audio tracks.

The AI Ensemble: A New Member of the Band

AI is rapidly becoming an invaluable member of the audio post-production team. It’s not about replacing the human element but augmenting it, removing the tedium to pave the way for the true artistry of sound. In McCartney’s experience, AI has proven to be a respectful collaborator, honoring Lennon’s legacy and bringing his voice into the present in a way that was once unimaginable.

As AI continues to refine its capabilities, the possibilities for post-production are expanding. From the restoration of vintage recordings to the crafting of live virtual performances, AI is not just an editor; it’s a restorer of legacies, an enhancer of experiences, and a bridge between the analog warmth of the past and the boundless potential of the future.

In this era of AI-enhanced audio, we stand at the precipice of a new frontier, one where every sound, every voice, and every memory can be brought to life with clarity previously thought unattainable.
