Hey HN! Braden here, creator of Whispering, an open-source speech-to-text app. I really like dictation. For years, I relied on transcription tools that were almost good, but they were all closed-source. Even a lot of them that claimed to be “local” or “on-device” were still black boxes that left me wondering where my audio really went. So I built Whispering. It’s open-source, local-first, and most importantly, transparent with your data. Your data is stored locally on your device, and your audio goes directly from your machine to a local provider (Whisper C++, Speaches, etc.) or your chosen…

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…

Greetings HN! I built Voice Isolate to be the simplest way to enhance any speech recording. After hearing so many videos/podcasts with great content but poor audio I realized not everyone can or wants to invest in a pro mic / studio / editing software but figured something simple should be possible now using AI. There are products that do this like Descript or ElevenLabs but I find they’re overcomplicated for many use cases (full blown app designed for professional podcasters, use a convoluted credit system, etc.). As a solo dev I wasn’t sure this was possible to do well but I…
