The Record Industry Can See Itself in the A.I. Mirror

The record industry (RIAA) officially opposes the use of copyrighted music for artificial intelligence, but industry practices are now firmly in the same business of reinvention.

You may have tried a quiz offered by several different social media sites inviting you to choose if a particular song is the work of A.I. or the real deal:  a recording with real musicians. So far my few attempts to sort out fake from authentic pop songs has been no better than chance. Do I really have a tin ear? Why was I so easily fooled? It’s not impossible. But something else is at work. For years, almost all pop music has been run through so many “tools” and alterations that it’s unrecognizable from its original forms. Overproduced tracks that have been around for years are nearly indistinguishable from A.I.-generated tracks.

One cue is to listen to the bass-heavy beat that drones along unaltered.  For a long time even “real” music has been using drum machines or “loop tracks” that lock onto a song and never change. Musicians don’t usually play that way. But synthesizers do, faking other instruments from digital samples that automatically repeat. And then another set of black boxes go to work on a singer who has a natural range that requires skillful adjustments at the top or bottom end of their musical range. No worries now about natural variations in a voice. Any less than perfect vocalizing can be tuned with pitch correction software. And we haven’t even talked about the extensive A.I.-like sampling used in hip-hop and other genres.

My point is that modern music has been so overproduced with studio effects that a singer’s natural performance has been obscured by endless “intelligent” circuits that have altered it. Modern producers and audio engineers can’t help themselves in their desire to make someone’s or some group’s natural sound even “better.” But that also makes them part of the problem. Pop music today is not simply a record of a single performance, but the result of labored audio construction that takes place in different places and at different times.

The twist  here is that while the record industry (RIAA) officially opposes the use of copyrighted music for artificial intelligence, it’s practices are firmly in the same business of electronic reinvention.

Where We Came From

All of this more or less started with Les Paul. His tape-delay overdubbing and “looping” were early applications applied to a particular pop standard, “How High the Moon” (1951). This novel recording gave his partner, the singer Mary Ford, a performance twin heard just a fraction of a second behind Mary’s first pass of the song. New and novel Ampex tape recorders adding tape-delay pleasantly thickened Ford’s voice and did the same for the new pick-ups that Les used on his guitars. To reproduce the track on television a few years later Paul proudly revealed these new recording tricks of multi-tracking and tape delay that would change the course of modern music. I can still recall being among the millions of Americans being mesmerized by the sound when I first heard it, in my case, coming from a jukebox in a café in Leadville Colorado.

Paul and Ford were an amazing and creative performers. But I’m afraid Paul paved the way for music to begin its long downward decline to being radically reshaped by circuits in a box: a harbinger of what A.I. does. No longer did recording engineers try to faithfully capture what was captured by a microphone. They soon became participants in augmenting the sounds of a performer with all kinds of electronic add-ons. This continued with Elvis Presley using various an effect called slap-back delay. And nearly every record producer started using the kind of added ambiance, especially reverberation, pioneered by Motown  and other labels. Today most pop singers also use Auto-Tune or pitch correction: producing real alterations of the natural variations common to even great singers. For some reminders of how straight “dry” recordings of performers sound like, listen to Frank Sinatra from the Capitol years in the 1960s, or, more recently, the pop-jazz singer, Laufey, who shuns most production add-ons. In the 1970s singer Karen Carpenter had an amazing voice and a broad range that was sometimes uselessly altered by unnecessary add-ons.

There are obviously many kinds of synthesizers that can add effects and sampled instruments on tracks: some “musical,” others uselessly intrusive. But the use of all mean that most pop recordings have been “enhanced” by layers of electronic devices that apply their own logics to a recording. The robotic line seems to be crossed when an engineer can preset an effect and simply allow it to alter the original acoustic sound.

In addition, all of the software and hardware needs to be duplicated on prerecorded tracks to be used when a group goes on the road. Audiences usually want to hear the studio experience rather than what the logistics of live performance would normally allow. For this reason concerts are often a mix of live and prerecorded segments, a sore point for some fans who notice the contributions of musicians who are not even on stage.

We can marvel at the electronics that can be patched in to alter recordings. Few engineers seem to be able to resist. My point is that those temptations make the complaints of the popular music industry about A.I. uncomfortably close to their standard operating practice.

A final example. There is something a bit sad about accounts of how the classic Paul Simon album Graceland was put together. There are some wonderful tracks on it that replicate the experience of a live performance. But as Ashley Kahn recounts in Days of Miracle and Wonder (2026), individual songs were not assembled in a studio in South Africa or on a stage in Zimbabwe in 1987, but a few years earlier in studios and mastering suites in New York, London, and Johannesburg.

Midcentury Musical Innovators

It would have been fun to have been in the room when this natural garage tinkerer stumbled on to what has since become the standard of multi-track recording. 

One of the pleasures of a writing project on how sound has been used and misused has been the discovery of some unlikely heroes who promoted key audio innovations.  Here’s five.

Bing, a Mic, and a Tape Recorder.  In his day, Bing Crosby was a mega-star with hugely popular recordings and radio shows.  In the 1930s his relaxed approach to singing in front of a microphone redefined what a public performance can be. In the older form of vaudeville, the energy of the performer did most of the ‘selling.’  In radio, the microphone made those over-the-top performances unnecessary.

Crosby eventually grew tired of the time constraints of live radio. So it was natural to seek a way to make recordings of shows and re-edit some others. The problem was that, in this period, powerful radio executives thought it was unacceptable for their networks to foist recordings on an unsuspecting public.  They expected their stars to show up in their living rooms in real time. Bing eventually broke the “no recorded programs” taboo, gaining more time to do other things in life, like playing golf.  The solution came in the form of the Ampex Corporation’s development of tape recorders modeled on pioneering work done by the Germans during World War II. Tape was a far superior medium for recording than “cutting” records directly to heavy shellac masters. In addition, it was possible to easily edit the quarter-inch PVC tape to delete mistakes or add additional material. He liked tape so much he bought shares in the company and gave away recorders to friends. The networks eventually succumbed.

Les Paul and Mary Ford ‘invent’ Modern Recording

Guitarist Les Paul received one of Bing’s tape machines.  At the time Paul was beginning to use a recently improved Gibson electric guitar: one of a new breed of solid-bodied instruments with two “pickups” that amplified the sound of the strings electronically rather than through the acoustic body. Because of a technical mistake he made while learning to use the recorder, Paul discovered that he could record sound over an existing track. It was then just a small additional step to record parts of one song on different tracks that played back together, often with a slight delay.  It would have been fun to have been in the room at the time when this natural garage tinkerer stumbled on to what has since become standard in the industry: multi-track recording.  We may no longer use tape for all recordings; computer audio files do more or less the same thing. But we still count on the ability to “build up” a recording in a studio from many separate tracks.

Adding rhythm and bass tracks in a multitrack recording of his own previously recorded melody line turned Les Paul into a one-man band, with no set of innovations coming together so clearly than in “How High the Moon,” released in 1951. Mary Ford’s slightly delayed voice melded with the multi-tracked guitar to produce a groundbreaking hit that wore out jukeboxes across the nation.

A Surprising Audio Pioneer.  Anyone visiting the Sony Studios in Culver City will find what is perhaps the most honored room for recording music in the United States, the Barbra Streisand Scoring Stage.  It is surely an honor to have her name associated with the space, which was the location where most of the spare-no-expense MGM scores of the 50s were recorded, not to mention music for more recent films as well. The largest session ever done on the historic stage used an 80-piece orchestra with a 100-person choir (Empire of the Sun).

The official reason for the honor was to give credit to the singer who regularly used the space to record sound tracks for Funny Girl and many of her 49 Gold Albums. There’s also a less official backstory as well. When Streisand was finishing her version of A Star is Born in 1976, she wanted to use the still-new Dolby surround format for the film.  But that meant pushing for better playback equipment in theaters scheduled to show the release. Many of them were still barely able to reproduce stereo sound. Using her considerable clout, Streisand demanded that bigger theaters improve their audio systems.

Please don’t cut me in two with that flashlight.  One classic piece of Hollywood lore is how the fabled sound designer Ben Burtt created the iconic effects of “lightsabers” slashing through the air. The distinctly electronic noise from the Star Wars series is now burned into our cinematic memories. The sabers were the preferred weapons of the future, but also a throwback to the swashbuckler films of the 1930s and 40s. Every action film needed a master dualist who could slice his way to dominance against villains who were as unlikable as Lord Vader.

Burtt came up with a blend that included sounds of an old movie projector motor he remembered from his days at USC, in addition to a nasty interference hum discovered when his microphone got too close to an old television set. Back then, a household filled with radios and televisions was an endless source of spurious electric interference that could rival Victor Frankenstein’s laboratory. That intrusive hum picked up by the microphone gave off a noise of bleeding electrons not so different from what someone might hear standing near a high-voltage substation. But a lightsaber was not fixed in place. Its sound needed to change when it sliced through the air. Burtt found that if he took what he recorded from his two sources and played them back, he could then wave another mic around and near the speaker, creating a Doppler effect where the pitch slightly raises and lowers as the mic moved by.  It’s indeed movie magic when a given sound turns a flashlight into an iconic movie weapon that has taken on a life of its own.
