iZotope 推出 Photon：AI 分轨与降噪应用

Ever needed just the vocal from a finished song? Or tried to rescue an interview buried under traffic noise? A finished file is supposed to be locked in, but with iZotope Photon, you’ve got the key.

Photon is a standalone app and ARA plugin for AI stem separation and audio cleanup. It’s powered by 12 custom-trained machine learning models that run right on your GPU. That means there’s nothing to upload, no usage cutoffs and no waiting in a queue. Split stems, clear out noise, even out levels, and pull apart conversations with up to six people talking.

When you need to get in, get it done, and get out, Photon’s got you.

Split any finished file into stems

Drop in any audio or video file and break it into the pieces you need: music, voice, sound effects, individual instruments, even individual speakers. There’s no session to set up. Pick a model, keep what you want, mute what you don’t, and export the rest.

Music 4 Stems: Got a finished song but no session files? Split it into vocals, drums, bass, and everything else. Use Music 4 Stems for quick tweaks, or grab Music 4 Stems Ultra for sharper separation when a stem needs to hold up on its own. It’s perfect for remixes and rebalances.
Voice Separator: People talking over each other? Voice Separator splits up to six voices into their own stems, plus room tone and background, so you can finally untangle the conversation in an exported stereo file.
Cinema 4 Stems: Split any video or audio file into voice, music, sound effects, and other elements. It’s handy for replacing music when a license runs out, pulling out quotes, and localizing video for foreign language versions.
Drums 5 Stems: Found the perfect snare to sample? Kicks not hitting hard enough? Break the kit into kick, snare, hi-hat, toms, and cymbals, from a drum bus or a full song.
Voice 2 Stems: Split any track into voice and music, then blend them however you like. It’s great for karaoke mixes or pulling music out from under your content.

iZotope Photon Music 4 Stems

Clean up audio from anywhere you hit record

Real-world audio is rarely perfect. Echoey rooms, rush-hour traffic, wind and tinny phone calls all sneak in. Photon’s cleanup models are named after the problem you’re actually dealing with, so you don’t have to work out what to fix. Pick the model that matches, set the strength, and Photon handles the rest, evening out levels and bringing voices forward along the way.

Voice Restore: Podcast guest sitting halfway across the room? Livestream mic sounding muffled? Voice Restore cleans up noise, levels, mic tone, and echo so every word comes through clearly.
Indoor and Indoor Noisy: Indoor clears out the noise and echo. For loud spaces like factory floors or busy event halls, reach for Indoor Noisy.
Outdoor, Outdoor Traffic, and Outdoor Wind: Shooting outside? Outdoor handles general background noise. Outdoor Traffic is trained on traffic and city noise. Outdoor Wind is built for real gusts on rooftops and coastlines, not just a light breeze.

The Indoor and Outdoor models do more than remove noise. They also even out levels and enhance voices automatically, so dialogue comes out clean and clear. They’re built for fast processing too, so you can preview, tweak, and export in a flash, even on long recordings.

Hear it before you commit

Jump to any spot in your file and Photon starts processing right there, so you’ll hear results in seconds. Not quite right? Nudge the strength, listen again, or try another model. There’s no session to build and no sitting around waiting.

Integrate Photon seamlessly into your workflow

Photon fits into the way you already work, whether you live in a DAW or spend your days in a video timeline.

In your DAW: The Photon ARA plugin puts the full Photon engine right on your timeline in Pro Tools, Sequoia, Samplitude, REAPER, Cubase, and other ARA2 hosts. Since ARA gives Photon the whole clip, it can use the full context of your audio. Stack several models, flip between them to compare, and keep the session moving.

With your video files: Drop your MP4, MOV, MKV, MXF, or MPG file straight into the Photon app. Clean up the dialogue, split out the music, or fix the noise, then export a new video file with the processed audio and your original picture untouched. ProRes files are supported too. There’s no extracting audio, no round-tipping, and no re-syncing, so you can go from upload to export without leaving Photon.

Working with a video file in iZotope Photon

No uploading to the cloud required

Everything Photon does happens on your own computer, powered by your GPU. Your audio never leaves your machine, which matters a lot when you’re working on embargoed material or files that aren’t yours to upload. No queue, no cutoffs, no interruptions.

Grow your toolkit with the Model Manager

Photon keeps growing. New and upgraded models show up in the Model Manager as they’re released, and you can download them and try them on whatever you’re working on right now. No reinstall required.

Two teams, one cutting-edge tool

Photon is the first joint research project from iZotope and Boris FX. It brings the expertise of two audio teams together, sharing tech so we can go further, faster.

How Photon and RX work together

Step	Reach for	What you’re doing
Get production-ready audio	iZotope Photon	Drop in a finished file, split stems or clean up the whole recording, and hear results right away. Deliverable audio, no session required.
Fix the tricky moments by hand	iZotope RX	Zoom in on the spectrogram to fix one-off problems, like a cough under a line, a phone ring, or a squeaky chair, by selecting exactly the sound you want gone.

If you already use RX, Photon is designed to sit right alongside it. Think paint roller and paintbrushes: grab Photon when you want to cover a lot of ground quickly, and RX when you need precise detail work. Each has its own models, so use whichever fits the job in front of you, or both.
