Cinema-Grade Film Mixing
& Technical Compliance
Your Technical Audio Mix Partner for Film
With TravSonic, you aren’t just running your film’s audio mix through a preset processor. You are partnering with an expert who is as invested in your project’s success as you are. We provide the peace of mind that our film audio mixing service will deliver. If a distributor has a question or a festival has a specific requirement, we are here to handle it.
Your creative vision deserves a technical finish that translates
The reality is that a great audio mix in your edit suite doesn’t always equal a great mix in a 300-seat theater or on a viewer’s smartphone.
Positioned between your locked edit and the QC lab, we ensure your film’s audio meets the rigorous delivery standards required by major global distributors. Our mission is to ensure your story isn’t just heard, but that it meets the rigorous audio delivery demands of Netflix, Amazon, and Global Broadcast standards without breaking a sweat.
Why the “Final Audio Bridge” Matters For Distribution
In the final stages of audio post-production, technical QC rejection is the ultimate bottleneck. We specialize in bulletproofing your final mixed audio by combining true critical listening with modern compliance workflows.
Translation Excellence: From the deep sub-bass of a theatrical LFE channel to the clear dialogue needed for a mobile “Web Mix.”
- Sound Level and Peak Compliance: We handle the math of LUFS, True Peak, and Leq(m) so you can stay focused on the storytelling.
- Accountability: Every master is backed by a full Master Batch Report, giving you the documentation your distributor’s QC team expects to see.
Theatrical 5.1 Surround Sound Masters
Audio Mixing | Translation You Can Trust
Does your film’s audio feel cinematic? When the audience sits down in a theater, they shouldn’t just hear your movie; they should feel like they are standing inside the scene. We focus on building a high-quality 5.1 Surround Sound master that uses the whole room. This means crisp dialogue in the center, immersive backgrounds in the back, and that deep bass that makes the floor shake during big moments.
Our goal is to give your film that “big studio” polish, no matter the size of your production. We make sure the soundstage feels wide and exciting without ever distracting from the story you’re trying to tell.
- Room to Breathe: We place sound effects and backgrounds carefully around the room so the world feels 3D.
- Dialogue is King: Your actors will never have to fight the music. We make sure every word is easy to understand, even in the middle of a loud action scene.
- Solid Bass: We add weight and impact to the low-end so your movie feels powerful but never sounds “muddy” or distorted.
Sound that works everywhere
An audio mix might sound great in a controlled studio, but it can fall apart when it hits a real theater if it isn’t handled right. We make sure your 5.1 print master is technically solid so it’s ready for a DCP (Digital Cinema Package) or a festival screening. We don’t just move sounds around for the sake of it. We build a stable environment that sounds great in every seat of the house, from the front row to the very back.
What you get in your hand
Once we finish the film mix, we give you a clean set of files that make the final hand-off to your distributor easy:
- Industry-Standard Master Files: High-quality 5.1 surround sound files ready for any theater, streaming, or broadcast system.
- Music & Effects Stems (MnE): Clean versions of your movie without the dialogue. You’ll need these if you ever want to sell your film internationally or have it dubbed into another language.
- Meeting Certified Levels: We mix specifically to meet the volume standards required by platforms like Netflix or Amazon.
Streaming & Web-Optimized Stereo Mixing (The “Small Speaker” Solution)
Sounding great on every screen
Most people today will watch your film in a home theater, on a laptop, a tablet, or a phone. While a big theatrical mix sounds incredible in a theater, those tiny speakers usually can’t handle the same range. If you just use a standard “auto-downmix,” your dialogue can get buried, and your music might lose its punch. We provide a specialized Streaming and Web Mix designed to fix this exact problem.
We carefully adjust the audio balance so that your movie sounds full and clear, whether someone is wearing headphones or listening through their phone’s built-in speakers.
- Focus on Clarity: We pull the dialogue forward so your actors are never drowned out by the score or sound effects on small speakers.
- Translation Testing: We check the mix on multiple real-world devices to make sure it “translates” perfectly from the studio to the web.
- Solid Stereo Image: We keep the sound wide and exciting without causing the “phasing” issues that make audio sound thin or hollow.
Solving the “Volume Jump” problem
Have you ever watched a video where you have to keep reaching for the volume remote because the music is too loud and the talking is too quiet? We solve that. By using our dedicated master chain, you meet the specific volume standards for platforms like YouTube, Vimeo, and Instagram. We make sure your film stays at a consistent, professional level from start to finish.
Reliable files for the web
When we deliver your Web Mix, it’s ready to be uploaded immediately. No more guessing if the levels are right or if the audio will clip when it hits the streaming servers.
- Streaming Optimized: Mixed to the exact loudness levels (-14 to -18 LUFS) that web platforms prefer.
- Peak Protected: We ensure your audio never distorts, even when web players apply their own extra processing.
- Sync Guaranteed: Your audio will stay perfectly locked to your picture, exactly how you intended.
Distribution-Ready Deliverables
Handing over a master that just works
The last thing you want after months of work is to have your film kicked back because a file was named wrong or a loudness level was off. We take that stress off your plate. When we wrap a project, we don’t just send a single audio file and call it a day. We deliver a complete Master Batch of assets that are organized, labeled, and ready for any distributor’s technical team.
We follow a strict checklist for every delivery, ensuring that your audio is as professional as your picture.
- Loudness Specs: Whether you are going to Netflix (-27 LUFS), TV (-24 LKFS), or YouTube (-14 LUFS), we calibrate your levels to meet the exact target for your platform.
- Safety First: Every mix is processed through our dedicated QC department before it is sent off.
- The Technical Specs Report: We include a TECHNICAL SPECS DOC file with every project. This is a document that lists your peak levels, average loudness, and format details—proving to your distributor that your film is technically sound.
Stems for the Future of Your Film
If you plan on selling your film internationally, you’re going to need more than just a final mix. We provide a full set of stems (separated tracks) so you are prepared for whatever comes next.
- M&E (Music & Effects): A version of your mix without the dialogue. This is a mandatory requirement for international sales and foreign language dubbing.
- D-M-E Stems: Separate tracks for Dialogue, Music, and Effects. These are essential for creating trailers, social media clips, or making small tweaks later without having to remix the whole movie.
- Frame-Accurate Muxing: We ensure your final audio is perfectly synced to your master video file, so what you see is exactly what you hear.
Organized for a Smooth Wrap
We believe that a professional project should look professional on your hard drive. We deliver your files in a clean, easy-to-navigate folder structure. No more hunting for “Final_v2_REMIX_FINAL2.” Just clear, industry-standard filenames that make your hand-off to the colorist or distributor completely seamless.

Frequently Asked Questions About Audio Mixing
Q: What is the difference between audio mixing and audio editing?
A: Audio editing is the ‘surgical’ process of removing noise, mistakes, and cleaning up dialogue. Audio mixing is the artistic and technical process of balancing those cleaned tracks, applying EQ and effects, and ensuring the final sound has depth, clarity, and meets professional loudness standards.
Q: Do you offer surround sound mixing online?
A: Yes, TravSonic specializes in immersive audio formats. We provide professional surround sound mixing and upmixing for film, trailers, and documentaries, ensuring your project is compliant with theatrical and streaming delivery specifications.
Q: What technical standards do your mixing services follow?
A: Our mixes are engineered to meet industry-standard loudness requirements, such as -24 LKFS for North American broadcast (ATSC A/85) and -23 LUFS for European standards (EBU R128), as well as specific targets for Netflix, Amazon, and Spotify.
Q: How do I prepare my files for online mixing services?
A: To get the best results, please provide “dry” consolidated WAV stems (24-bit/48kHz preferred) with all background noise and verbal flubs removed. If you need help with the cleanup phase, we recommend our specialized audio editing services before the mixing begins.

- Locked Picture Master: High-res ProRes or DNxHD file with “burned-in” timecode (BITC) for frame-accurate reference.
- OMF or AAF Handover: Your full timeline with at least 2-5 second handles. Please ensure tracks are cleanly labeled (e.g., “Boom_Scene1”, “Lav_Hero”).
- Guide Track: A reference audio track exported directly from your NLE to ensure perfect sync.
- Theatrical or Web Target: A clear understanding of your primary destination (Theater, Netflix, YouTube) so we can calibrate our monitors and limiters accordingly.
- Music Cue Sheet: For tracking rights and ensuring your “Music-Only” stems are properly archived.
