Cinema-Grade Film Mixing
& Technical Compliance
Technical Audio Mixing Partner For Your Film
When you trust TravSonic with your project, you're not just using us to polish your audio. You'll work with someone who wants your film to succeed as much as you do. As soon as the distributor or film festival makes a special request for your audio, we are on deck to deliver.
Ensuring Your Film's Audio Translates Seamlessly to Every Platform
As you adjust the audio in your edit bay, the mix will rarely translate to a large theater or even someone's phone. By providing services between your picture lock and QC, we allow your film to meet distribution specs for all major distributors. You can focus on getting your story out there while we worry about getting your audio to spec.
What does this mean for your film's final distribution?
The last hurdle for a film is technical audio QC on its final mix. That's where we step in. Using both ears and advanced tech, we can bulletproof your final mixed audio.
- Translation Excellence: Have your audio translate from the big cinema to the comfort of the home theater or laptop.
- Sound Level and Peak Compliance: We'll make sure your film is at proper loudness levels for theatrical, broadcast, and streaming.
- Accountability: By providing you with a Master QC report, you can show your distributor the final audio spec details they need to see.
Theatrical 5.1 Surround Sound Masters
Is your movie's audio cinema quality?
When someone watches your film, they want to be engulfed in the world you're creating. We take the time to create a quality 5.1 Surround Sound master that fills the room. With clear dialogue front and center, surround sound will make the viewer feel as if they are in the movie.
- Room to Breathe: Sound effects and backgrounds are positioned throughout the mix environment to give you a sense of space.
- Dialogue is King: The dialogue will always be front and center, guaranteeing to be heard clearly at all times. Even if your movie is action-packed, you will be able to hear what they are saying.
- Solid Bass and LFE: We process low frequencies to ensure your film feels punchy. But we won't go overboard and make your film sound muddy.
Sound that works everywhere
Your mix may sound awesome on the studio monitors, but once it's in the theater, it can be a different story. The film's 5.1 print master will meet the technical specs to get your movie out to a DCP (Digital Cinema Package) for screenings and festivals. We will give you a surround environment that will translate to anywhere in the theater. Front row or back.
What you will get
When your film is mixed and mastered, we will supply you with everything below so you can hand it off to your distributor.
- Master Files: You will receive your film in all the required audio formats for theaters, streaming, broadcast, and web.
- Audio Stems: Isolated audio exports for dialogue, sound effects, Foley, and music.
- Loudness Levels: Your film will be mixed to meet loudness standards for distributors such as Netflix and Amazon.
Streaming & Web-Optimized Stereo Mixing (The "Small Speaker" Solution)
Sounding great on every screen
People will most likely be watching your film on their home theater system, laptop, tablet, cell phone, etc. They will all have smaller speakers and will not be able to produce what your theatrical mix is capable of. Using a simple auto downmix will cause your dialogue to get lost in your film. Music will not be as impactful either. That's why we offer our Streaming and Web Mix.
We want to make sure your film has the best possible translation to headphones, laptop, and cell phone speakers.
- Dialogue Forward: By enhancing the front of your dialogue, we allow your film to not get lost in the score and FX on smaller speaker systems.
- Translation Testing: Making sure your mix will translate well from our studio to the web.
- Solid Stereo Image: Allows for a nice stereo field in your film but won't give you the phase problems that come with that.
Solving the "Volume Jump" problem
You know that feeling when you're watching something and the music is too loud and you're trying to turn up your dialogue? Well, we fixed that. With our process, we allow your film to be at a constant level that fits within YouTube, Vimeo, and Instagram specs.
Reliable files for the web
Your web mix will be upload-ready! No worries about clipping or having to guess what your levels are.
- 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
No one wants their film rejected due to bad file naming conventions or improper loudness. We make sure that never happens to you. Once our projects are completed, we will provide you with everything you need in a Master Batch of files. These will be correctly named and formatted for distribution.
Every delivery will meet these requirements:
- 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're looking to distribute your film overseas, you will need more than just your final mix. We provide all required mixes and stems to get you ready for what may come.
- 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
It's how we feel about your files when it's done as well. We want your project to look professional on your hard drive. Your files will be delivered with proper file names, organization, and ready to give to your distributor with ease.

Frequently Asked Questions About Audio Mixing
What is the difference between audio mixing and audio editing?
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.
Do you offer surround sound mixing online?
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.
What technical standards do your mixing services follow?
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.
How do I prepare my files for online mixing services?
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.

"Get Started" Project Delivery Checklist

- 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.
