Trama – AI Stem Separator

Ever try to flip a crazy vintage sample, but the original drums keep clashing with your modern 808s? Or maybe you found the perfect vocal run for a remix, but the muddy bassline underneath is completely ruining the vibe. We’ve all been there, spending hours tweaking EQs and phase cancellation tricks just to make a sample sit in the mix, only for it to still sound washed out.

Enter Trama. This fully offline, AI-powered stem separator is an absolute cheat code for producers, remixers, and beatmakers. Powered by Meta’s Hybrid Transformer Demucs model, it takes your fully mixed stereo files and surgically extracts the stems you need, right on your hard drive.

Why Trama is a Game-Changer for Your Mix & Workflow

Surgical Stem Isolation: Choose between vocals, drums, bass, and “other.” Want just the acapella? Easy. Need to rip a clean drum break? Done. Anything you don’t select gets automatically summed into a single “other” track to keep your session clean.
Zero Internet Required: Unlike cloud-based splitters that charge subscriptions and make you wait in queues, Trama runs fully offline. Your files stay local, and the processing happens on your rig.
Pristine Headroom: You can feed it WAV, AIFF, MP3, or FLAC, and it will always spit out 32-bit float WAVs. That means maximum audio quality and infinite headroom when you drag those stems into your DAW.
Workflow on Steroids: Got a whole crate of tracks to separate? The batch processing lets you drag and drop a whole folder. You can queue them up, pick your quality preset (Normal, High, or Ultra), and go grab a coffee while the AI does the heavy lifting.
Keeps Your Metadata Intact: This is huge for workflow. BWF data, cue points, ID3 tags, and even Reaper markers are copied perfectly from the original file to your new stems.

⚡ Pro Producer Tip: Build Custom Breakbeats

Don’t just rip acapellas! Run old 70s soul or jazz records through Trama to isolate the drums. Take that raw drum stem, chop it up, add some heavy tape saturation and parallel compression, and you’ve got a completely unique, royalty-free breakbeat that absolutely slaps. It’s the ultimate secret weapon for lo-fi and boom-bap producers.
