How do you appreciate something you can’t see? Something that is not supposed to be noticed, but has to make something else stand out?

That is film sound. You should not be aware of it. You should be aware of the story, the film. Be one with the character. Not listen to the birds, or the dog that walks past a hundred feet away for a few seconds.

Who would know that the posh hotel in the film is a 10 x 10 set? That the punch is inches away from the face? People say sound is 20% of the impact. I don’t believe that. If not 50%, it is at least 49.9%. Why? Would a dinosaur scare you by its looks alone? And it is not only the sound. It is the silence too, and where you place it.

So, are we magicians? Maybe not. But we are definitely illusionists.

I have spent more than two decades with that paradox, with over 250 films, multiple languages and countless discussions in dark rooms. This book is a collection of the knowledge that I wish I had with me at the start of my career. There is technique in here. There is also the part we call intuition, only because we have not yet found a better word for it.

What’s Inside

We start with the room, because everything you hear passes through it. Part I is the room and the system: ratios, levels, the LFE, Dolby Atmos, panning, signal flow, clocking, and a chapter on what to do when things go wrong.

Part II is the session itself, from the first conversation to how I set up Pro Tools and the console, and what a mix day actually looks like.

Part III is delivery. The deliverables, mastering, loudness and translation, and the work that carries on after the mix is approved.

And Part IV is the craft. Dialog, effects, music, reverb, emotion, the final mix, and a few techniques of my own. It closes with a chapter for my associates.

About Me

I’m Sreejesh Nair, and most people call me Sree. I started out in 2003 as an assistant re-recording mixer at Rajkamal Studios in Mumbai, which later became FutureWorks, and grew up there into a senior re-recording mixer. Since then I’ve mixed around 250 films in Hindi, English, Marathi, Malayalam, Tamil, Gujarati, Kannada and Telugu. Among them are Gangs of Wasseypur, Agneepath, Kaminey, Paa, Bombay Velvet, Udta Punjab, Jawan, The Legend of Maula Jatt and Jigra. Early on, I also mixed the dubbed versions of Hollywood releases, from the Harry Potter films to Inception and 300.

When Dolby Atmos came to India, I was part of the team behind the country’s first Atmos mix theater, and the first Dolby Atmos Premiere mix room anywhere in the world. Most of my mixing since has been in Atmos.

Gangs of Wasseypur brought me the National Film Award for Best Re-recordist of the Final Mixed Track. The documentary A Few Sound Men brought four IRAA Awards in 2020, and in 2024 came an IRAA for immersive music mixing.

These days I split my time between Kochi and Dubai. I’m a Solutions Specialist for Pro Audio at Avid, looking after the Middle East, Africa, the Indian subcontinent, Central Europe and Turkey, and I present the Film Sound Workflow Secrets video series for them. In Kochi, I founded AuO2 Studio in 2019, the first TPN-certified studio in Kerala. I’ve been visiting faculty at FTII for more than ten years, and at SRFTI and TAG, I’ve run more than two hundred masterclasses, and I run the AudioEducationForAll initiative.

The rest of the time, I write at film-mixing.com, which is where several chapters of this book began.
