Sonic Grading, Part 1: Why Your Perfect Sample Library Sounds Wrong

“It feels too modern. It sounds like a music hall.”

That was the director's feedback on an orchestral cue I'd written for a pivotal, violent scene in an independent psychological drama. The balance was clean, the harmony worked, and the sample libraries sounded gorgeous. But the orchestra didn't seem to belong in the film.

The temp track was a recording of “Veris leta facies” from Carl Orff's Carmina Burana. A temp track is music used as a reference while a film is being edited, and this one had a heavy, oppressive quality that my cue was missing. I heard what sounded like sustained pipe-organ tones, a choir, and a weight I associated with church music.

The scene called for a 1960s Italian liturgical atmosphere. I was giving it a pristine symphony concert.

Finding the right place

The mismatch became clearer while I was choosing an organ. I was considering a huge symphonic sound, something in the neighborhood of Interstellar, alongside Spitfire Audio's Union Chapel organ.

The symphonic organ was impressive, but it was wrong for the picture. The scene didn't need a massive concert hall; it needed a dusty chapel.

That image gave me something useful to work toward. My first instinct had been to reach for the faders, tweak the EQ, or change the notes. Those were still useful tools, but I needed a clearer idea of what I was asking them to do.

I started thinking about color grading. The same footage can suggest a sun-bleached 1970s film or a cold modern thriller, depending on the choices made in post. Could I think about the sound of the orchestra in a similar way?

I've started calling this sonic grading: shaping the sound of a recording to fit the world of the film. I'm using familiar production tools, but choosing them for what they say about the scene.

The notes, harmony, and instrumentation matter, of course. So does whether the ensemble seems close, distant, polished, weathered, or out of place.

For this cue, those decisions felt like part of writing the music. I couldn't separate the sound I wanted from what I wanted the scene to feel like.

Listening beyond the notes

To understand the temp, it helped me separate three things I might be responding to:

• The composition: The melody, harmony, orchestration, and style. These are the things I'm most used to studying as a composer.
• The performance and the room: The ensemble, the conductor's choices, the space, and the character of that particular performance.
• The recording: The microphones, their placement, the recording medium, and the choices made in production.

Those three layers gave me a starting point for listening. I could ask more than “What instruments are playing?”

When the director said they wanted the cue to feel like the temp, which part did they mean? I had been concentrating on the composition, while some of what drew us to the reference seemed to be in the performance and recording.

Sometimes the sound we want to reproduce may not have been a deliberate choice at all. It might come from a room, a limitation of the equipment, or something that happened during that session. We inherit those accidents as if they were choices.

That possibility changed how I approached the cue. Before deciding what to write or which library to load, I needed to listen more carefully to what the reference was doing against the picture.

Next: In Part 2, I get into the room, the choir blend, and the tonal choices.
