Every couple of seconds a fresh Solana block comes in and its transactions are played as notes: swaps pluck, launchpads chime, oracles tick, large SOL moves hit the sub. Audio stays silent until you press power.
Audio is off until you switch it on. The scope runs regardless.
Every sound is generated live in your browser with WebAudio. There are no samples, no libraries and no recording.
About every 2 seconds the server pulls the newest confirmed block from Solana's public RPC (getBlock, full transactions) and sends a compact list: program family, fee, SOL moved, success and compute.
Each non-vote transaction is routed by the programs it touches, in this order: launchpad, aggregator, DEX, NFT, lending, oracle, transfer. Every family has its own synth voice.
The fee paid sets velocity on a log scale. Pitch follows compute usage, snapped to the selected scale, so heavier transactions land lower.
Any transaction moving 5 SOL or more fires a bass note. Larger moves ring longer and louder.
Validator votes, usually more than half of each block, feed a soft background drone whose filter opens as the vote count rises.
Blocks carry hundreds of transactions. The density knob sets how many are played, taken evenly through the block, plus every large move, spread out until the next block lands.
