EchoPass · x402
A real-time soundscape metering protocol for live performance. Audio engineers use an x402-enabled DAW plugin to 'check out' high-fidelity environmental presets. Each time a specific atmospheric trigger is fired during a show (100ms of grain-delay, a specific synth patch, or a spatialized reverb tail), a 0.01 USDC event is signed by the sound board's Magic Link email sign-in. This facilitates per-staged-use revenue for sound designers, replacing flat-fee licensing with live usage settlement. Audience members can pay per-stroll to 'Unlock Live Stem' via QR to listen to isolated audio layers on their devices.
The primitive.
Access to the sound design engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so directors — or the agents working for them — pay per query and get a HashScan receipt every time.
Why this primitiveTheater designers are often underpaid for 'background' assets. By moving from static NFT minting to a pay-per-trigger model, the sound designer transitions from a one-time seller to a micro-royalty participant in every night's performance. The HTS transfer flow ensures the board operator doesn't need to manually sign transactions during a live cue sequence.
