How we create the soundtrack for Paramount's Chopper Cops

Behind the Scenes: Mixing the Action-Packed Audio for Chopper Cops

By Nicole Pfledderer, Audio Mixer at Dallas Audio Post


The Challenge: A Lot of Audio, A Lot of Action

One of the first things that struck me about Chopper Cops was how diverse the audio sources were. We had everything from body cam footage and police radio transmissions to helicopter headsets and sit-down interviews. Each of these came with its own set of challenges. The body cam audio was often rough, the police radios were full of static, and the helicopter headsets? Wind noise and distortion were a constant issue. Meanwhile, the sit-down interviews were recorded in a variety of different spaces with all kinds of room noise and reverb.

The key was finding a way to make all of this work together. How do you make a scene with helicopters flying overhead and cars screeching down the street sound exciting, but also ensure you can understand important radio communications? And how do you clean up those interviews that were recorded in less-than-ideal spaces so they blend seamlessly with the rest of the show?


My Approach: Balancing Excitement with Clarity

Taming the Radios & Body Cam Audio

One of the biggest challenges was dealing with the police radios and body cam audio. These were often full of static or distortion, which can be tough to clean up without losing the natural feeling of the recordings. For this, I used a trick that’s become one of my go-tos: a de-esser. Normally, we use de-essers to tame harsh “S” sounds in vocals, but here, I set it to target the specific frequencies where the harsh radio noise was most prevalent. This helped smooth things out without adding extra processing or plugins to the chain. It’s like using the de-esser as a dynamic EQ to reduce those problematic frequencies, making the radio chatter clearer while still keeping that real-world grit.

Mixing the Interviews

The sit-down interviews were another big part of the mix. They were recorded in a variety of spaces with different acoustics, so one of the first things I did was work on making them sound consistent. I applied custom EQ and reverb treatments to minimize the differences in room tone and make each interview feel like it came from a similar environment. It’s a balancing act—getting rid of distracting room noise while still making sure the dialogue feels natural and not overly processed.

Creating an Immersive Action Experience

The action scenes are where things really got exciting, but it was important not to let the excitement drown out the critical moments. I focused on creating a dynamic range that allowed for big, loud moments when needed (like during a helicopter chase), but also made sure there were quieter, more intimate moments that could breathe. This gave the mix room to build up tension in the quieter scenes, then explode into action when it was time.

I also paid a lot of attention to the sound design for the action sequences. The key to making those chases and helicopter scenes feel real is making sure the sound placement feels immersive. I wanted the audience to feel like they were in the action—whether they were in the helicopter, on the ground, or racing through the streets. The sound effects needed to be layered carefully to enhance that experience while still allowing the dialogue and radio communication to cut through.

Keeping It Broadcast-Ready

A big part of my role was ensuring that all of this excitement stayed within broadcast standards. Chopper Cops is a high-energy show, but it still had to meet the technical loudness requirements for broadcast. This meant constantly keeping an eye on dynamic processing and making sure we weren’t hitting any peaks that would push the mix out of spec. At the same time, I wanted the mix to feel cinematic and big—so finding that balance was key.

The Result: A Thrilling, Clear, and Cohesive Sound

In the end, I think we really nailed the sound of Chopper Cops. The final mix is immersive and exciting, with a dynamic range that keeps the audience on the edge of their seats while still allowing the dialogue and radio chatter to come through loud and clear. The action is intense, but it doesn’t overwhelm the story, and the interviews sound polished and cohesive even though they were recorded in so many different environments.

It’s a good example of how complex, action-driven sound can be handled in a way that meets both the emotional needs of the show and the technical demands of broadcast.


Closing Thoughts: What Makes This Work So Fun

What I love about working on shows like Chopper Cops is the challenge of balancing technical audio work with the sound design. It’s about making sure everything sounds real and exciting, while also ensuring the viewer can follow the story and understand the dialogue. It’s a delicate dance, but when it all comes together, it’s incredibly rewarding.

I’m proud of the work we did on this show, and I’m already looking forward to the next project that challenges me in a new way.
