Live audio that sounds like the room
PulseCast is live audio - rooms, shows and podcasts - that stays crisp and in sync for thousands of listeners at once. We built the real-time pipeline so hosts sound like they're in the room, wherever the audience is.

From source to screen
Four stages, each independently observable, so the real bottleneck surfaces in seconds - not during a live event.
Capture
Speaker audio is captured and cleaned at the edge, close to where it's spoken.
Mix
Voices are mixed in real time into a single, balanced live stream.
Encode
An adaptive ladder prepares quality tiers for every connection.
Distribute
An elastic edge fans the stream out to the whole audience, in sync.
Latency you can hear
Conversation falls apart when audio lags or drifts out of sync, and quality that's fine for one listener buckles when thousands arrive at once. PulseCast needed real-time audio that stayed low-latency and crisp as a room scaled from a few people to a stadium.
We split the problem: a low-latency real-time path for the people talking, and an elastic distribution path for everyone listening. Adaptive quality keeps audio smooth on any connection, and the whole pipeline is instrumented so we tune what listeners actually hear.
PulseCast now hosts live rooms that stay conversational for speakers and crisp for tens of thousands of listeners, across web, iOS and Android. Hosts sound present, listeners stay in sync, and the platform holds up when a show goes big.
What keeps it smooth
Real-time speaker path
The people talking get a low-latency route tuned for natural, back-and-forth conversation.
Elastic listener scale
Distribution scales with the crowd, so a room can grow from ten to fifty thousand without breaking.
Adaptive audio quality
Each listener gets the best quality their connection can carry, staying smooth instead of stuttering.
Recording & replay
Live shows are captured cleanly for on-demand replay the moment they end.
Crisp on mobile
Native iOS and Android apps keep audio clear on flaky networks and in the background.
Live audio metrics
Sync, dropouts and join time are measured as listeners feel them, not just at the server.

“Our biggest live show used to be our scariest day. With PulseCast's pipeline, it's just another room.”
