Mixing AI-Generated Stems with Live Session Recordings: A Practical Guide
AI stems and live recordings come from different signal chains. Getting them to sit together cleanly requires understanding where the differences actually are — reverb, dynamics, spectral space, and groove.
AI Music Copyright in the UK and EU: What Changed in Early 2026
The UK IPO clarified its computer-generated works position. The EU AI Act's transparency requirements produced their first enforcement actions. Here's what it means for production teams using generative audio commercially.
Adaptive Audio for a 40-Hour RPG: What We Learned Delivering Stems at Scale
1,400 stem files across 80 zones, 4 combat tiers, and 12 ambient states. Here's what broke, what we fixed, and what we'd do differently on the next project of this scope.
Latency Benchmarks for Real-Time Stem Generation: Where We Are Now
We instrumented every stage of our generation pipeline and benchmarked across four output duration tiers. P50 numbers, where the time actually goes, and what real-time threshold means in practice for production workflows.
What Production Professionals Actually Want from AI Music in 2026
Not a library. Not a DJ. Professionals want: stems, sync clearance, revision granularity, and API access. Here's what we heard from agencies, game studios and editorial teams over the past year.
Podcast Background Music: How Stem Separation Solves the Ducking Problem
Ducking background music under a voice track works perfectly when you have the isolated rhythm and melody stems. With a mixed master, you're fighting the full frequency stack. Here's the difference in practice.
How We Isolate the Harmony Stem: A Technical Walk-Through
Harmony stem isolation is the hard part. Melody and rhythm separate cleanly from frequency analysis. Harmony — chords, pads, tension — bleeds into both. Here's how our model approaches the problem.
The Music Revision Cycle: Why It Kills Ad Campaign Schedules and What to Do About It
The first draft is never what the client wanted. The third draft is what they agreed to. That revision gap eats 4–6 days from a campaign schedule — here's how production teams are starting to close it.
Game Audio Budget Breakdown: Where Indie Studios Actually Spend Their Audio Money
Based on conversations with 12 indie and AA game studios: what goes in the audio budget, what gets cut first, and how adaptive music ambitions collapse against composer availability.
WAV vs MP3 in Post-Production: Why Lossy Audio Is a Problem Your Editor Will Find
MP3 artefacts survive the first export. They do not survive three generations of conform and recompress. Here's why 24-bit WAV stems are the non-negotiable baseline for professional delivery.
Composer vs AI Music Generation: The Real Cost Comparison Nobody Publishes
A mid-tier composer revision cycle costs £1,800–£4,500 for a 60-second spot. Here's what the actual cost structure looks like, and where AI generation changes the economics.
How to Write a Music Brief That AI Can Actually Use
Tempo, mood, reference track, instrumentation cues. The difference between a brief that produces generic output and one that produces something usable comes down to three specific inputs.
The Content ID Problem: Why Stock Music Creates Claims Even When You Paid for It
You licensed the track. YouTube still claimed it. Here's why Content ID hits licensed stock music and what original generation actually protects you from.
Adaptive Music in Wwise and FMOD: Why Stem Separation Is the Starting Point
Most adaptive music middleware assumes you have separated layers — melody, harmony, rhythm. But most composers deliver mixed masters. Here's the workflow gap and how to close it.
Sync Licensing 101 for Advertising Producers: What You're Actually Paying For
Master use, sync rights, blanket licenses — the language of music clearance is designed to confuse buyers. This is what actually matters when you're clearing a track for a broadcast campaign.
What Are Stems? Why Production Teams Need Separated Tracks, Not Mixed Masters
A stem is an isolated audio layer — melody alone, harmony alone, rhythm alone. Here's why the difference between a stem set and a mixed master changes everything about your post-production workflow.
