    Hey HN, we've been working with OpenAI for the past few months on the new Realtime API. The goal is to give everyone access to the same stack that underpins Advanced Voice in the ChatGPT app. Under the hood it works like this: - A user's speech is captured by a LiveKit client SDK in the ChatGPT app - Their speech is streamed using WebRTC to OpenAI’s voice agent - The agent relays the speech prompt over websocket to GPT-4o - GPT-4o runs inference and streams speech packets (over websocket) back to the agent - The agent relays generated speech using WebRTC back to the user’s device The…

    Hi All ,I been working on my idea , A Voice CRM solution for 2 years.When I started brainstorming the idea the only option I have to receive phone calls thru browser was a flash widget or use 3rd party providers like Twilio or Phono . Thanks to WebRTC we now integrated our VoIP services to receive and make calls directly thru browser .Please have a look and give us your feedback .Thanks Voz.io Team .

    Hi HN, I’ve been working on a browser-based tool for exploring and debugging Web Audio API graphs. Web Audio Studio lets you write real Web Audio API code, run it, and see the runtime graph it produces as an interactive visual representation. Instead of mentally tracking connect() calls, you can inspect the actual structure of the graph, follow signal flow, and tweak parameters while the audio is playing. It includes built-in visualizations for common node types — waveforms, filter responses, analyser time and frequency views, compressor transfer curves, waveshaper distortion, spatial…

    Hey HN! I’ve written a bunch of WebSocket servers over the years to do simple things like state synchronization, WebRTC signaling, and notifying a client when a backend job was run. I realized that if I had a simple way to create a private, temporary, mini-redis that the client could talk to directly, it would save a lot of time. So we created DriftDB. In addition to the open source server that you can run yourself, we also provide https://jamsocket.live where you can use an instance we host on Cloudflare’s edge (~13ms round trip latency from my home in NY). You may have seen my…

    Hi HN! Last year the project I launched here got a lot of good feedback on creating speech to speech AI on the ESP32. Recently I revamped the whole stack, iterated on that feedback and made our project fully open-source—all of the client, hardware, firmware code. This Github repo turns an ESP32-S3 into a realtime AI speech companion using the OpenAI Realtime API, Arduino WebSockets, Deno Edge Functions, and a full-stack web interface. You can talk to your own custom AI character, and it responds instantly. I couldn't find a resource that helped set up a reliable, secure websocket (WSS) AI…

    AOO is a lightweight and flexible peer-to-peer audio streaming and messaging solution. It allows to send audio and messages in real-time and on demand between network endpoints - not only in local networks, but also over the public internet! The C/C++ library can be easily embedded in host applications or plugins. It even runs on embedded devices, such as the ESP32. In addition, the project contains a Pure Data external and a SuperCollider extension. The following article provides a high level introduction and demonstrates some use cases:…

    VoiceLine has built a chrome extension that allows you to record, share, and play voice notes within any browser-based application. We’re using an STT model to transcribe your notes into what we call a VoiceLine, a hybrid audio-text snippet, to address the problems of conventional voice messaging. Since we’ve been in closed beta as a seed-stage startup, here’s a direct link to get access: https://app.getvoiceline.com/6b29fbc80d Our vision is to introduce a new category of professional voice communication by building our service as a layer, not yet another instant messenger…

    I built a Chrome extension that acts as a WebSocket proxy, allowing real-time monitoring, message simulation, and traffic interception. Think "Proxyman for WebSockets" but integrated into Chrome DevTools. Key features: Real-time WebSocket monitoring and message capture Send custom messages in both directions (client ↔ server) Block incoming/outgoing messages for testing Background monitoring (captures connections even when DevTools is closed) Why: I was debugging a WebSocket chat app and needed better tools than browser DevTools. Existing solutions required external proxies or were too…
