Show HN: Gapless.js – gapless web audio playback
Hacker News (score: 10)Show HN: Gapless.js – gapless web audio playback Hey HN,<p>I just released v4 of my gapless playback library that I first built in 2017 for <a href="https://relisten.net" rel="nofollow">https://relisten.net</a>. We stream concert recordings, where gapless playback is paramount.<p>It's built from scratch, backed by a rigid state machine (the sole dependency is xstate) and is already running in production over at Relisten.<p>The way it works is by preloading future tracks as raw buffers and scheduling them via the web audio API. It seamlessly transitions between HTML5 and web audio. We've used this technique for the last 9 years and it works fairly well. Occasionally it will blip slightly from HTML5->web audio, but there's not much to be done to avoid that (just when to do it - lotta nuance here). Once you get on web audio, everything should be clean.<p>Unfortunately web audio support still lacks on mobile, in which case you can just disable web audio and it'll fallback to full HTML5 playback (sans gapless). But if you drive a largely desktop experience, this is fine. On mobile, most people use our native app.<p>You can view a demo of the project at <a href="https://gapless.saewitz.com" rel="nofollow">https://gapless.saewitz.com</a> - just click on "Scarlet Begonias", seek halfway in the track (as it won't preload until >15s) and wait for "decoding" on "Fire on the Mountain" to switch to "ready". Then tap "skip to -2s and hear the buttery smooth segue.
Show HN: Govbase – Follow a bill from source text to news bias to social posts
Hacker News (score: 65)Show HN: Govbase – Follow a bill from source text to news bias to social posts Govbase tracks every bill, executive order, and federal regulation from official sources (Congress.gov, Federal Register, White House). An AI pipeline breaks each one down into plain-language summaries and shows who it impacts by demographic group.<p>It also ties each policy directly to bias-rated news coverage and politician social posts on X, Bluesky, and Truth Social. You can follow a single bill from the official text to how media frames it to what your representatives are saying about it.<p>Free on web, iOS, and Android.<p><a href="https://govbase.com" rel="nofollow">https://govbase.com</a><p>I'd love feedback from the community, especially on the data pipeline or what policy areas/features you feel are missing.

Show HN: Try Archetype 360 – AI‑powered personality test, 3× deeper than MBTI
Show HN (score: 5)Show HN: Try Archetype 360 – AI‑powered personality test, 3× deeper than MBTI Hi there, are you familiar with MBTI, DiSC, Big Five? Well I'm experimenting with a new kind of personality test, Archetype 360, and I'd love for you to try it for free and tell me what you think.<p>- 24 traits across 12 opposing pairs -- that's three times more dimensions than MBTI or DiSC, so you get a much more nuanced profile. - A unique narrative report generated with AI (Claude), written in natural language instead of generic type blurbs. - Your role, goals, and current challenges are blended into the analysis, so the report feels relevant to your real‑life context, not just abstract traits.<p>It's an "ephemeral app" so your report only lives in your browser, there's no login, and we don't store your data. Make sure you save the report as a PDF before you close the page.<p>What I'm looking for is honest feedback on your archetype and report:<p>- Did it feel accurate and "wow" or just meh? - Did you learn anything unexpected about yourself? - What did it miss or not go deep enough on?<p>I'll use your feedback to refine the prompts and the underlying model. Just comment here or use the feedback form in the app.<p>If there's enough interest, the next step is to combine Archetype 360 with a variation of Holland Codes / RIASEC (vocational interest areas) to create a full‑power professional orientation report.<p>What else would you love to see? Ideas welcome!<p>Best wishes, Daniel

Show HN: Web Audio Studio – A Visual Debugger for Web Audio API Graphs
Hacker News (score: 29)Show HN: Web Audio Studio – A Visual Debugger for Web Audio API Graphs Hi HN,<p>I’ve been working on a browser-based tool for exploring and debugging Web Audio API graphs.<p>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.<p>It includes built-in visualizations for common node types — waveforms, filter responses, analyser time and frequency views, compressor transfer curves, waveshaper distortion, spatial positioning, delay timing, and more — so you can better understand what each part of the graph is doing. You can also insert an AnalyserNode between any two nodes to inspect the signal at that exact point in the chain.<p>There are around 20 templates (basic oscillator setups, FM/AM synthesis, convolution reverb, IIR filters, spatial audio, etc.), so you can start from working examples and modify them instead of building everything from scratch.<p>Everything runs fully locally in the browser — no signup, no backend.<p>The motivation came from working with non-trivial Web Audio graphs and finding it increasingly difficult to reason about structure and signal flow once things grow beyond simple examples. Most tutorials show small snippets, but real projects quickly become harder to inspect. I wanted something that stays close to the native Web Audio API while making the runtime graph visible and inspectable.<p>This is an early alpha and desktop-only for now.<p>I’d really appreciate feedback — especially from people who have used Web Audio API in production or built audio tools. You can leave comments here, or use the feedback button inside the app.<p><a href="https://webaudio.studio" rel="nofollow">https://webaudio.studio</a>

Show HN: Omni – Open-source workplace search and chat, built on Postgres
Hacker News (score: 53)Show HN: Omni – Open-source workplace search and chat, built on Postgres Hey HN!<p>Over the past few months, I've been working on building Omni - a workplace search and chat platform that connects to apps like Google Drive/Gmail, Slack, Confluence, etc. Essentially an open-source alternative to Glean, fully self-hosted.<p>I noticed that some orgs find Glean to be expensive and not very extensible. I wanted to build something that small to mid-size teams could run themselves, so I decided to build it all on Postgres (ParadeDB to be precise) and pgvector. No Elasticsearch, or dedicated vector databases. I figured Postgres is more than capable of handling the level of scale required.<p>To bring up Omni on your own infra, all it takes is a single `docker compose up`, and some basic configuration to connect your apps and LLMs.<p>What it does:<p>- Syncs data from all connected apps and builds a BM25 index (ParadeDB) and HNSW vector index (pgvector) - Hybrid search combines results from both - Chat UI where the LLM has tools to search the index - not just basic RAG - Traditional search UI - Users bring their own LLM provider (OpenAI/Anthropic/Gemini) - Connectors for Google Workspace, Slack, Confluence, Jira, HubSpot, and more - Connector SDK to build your own custom connectors<p>Omni is in beta right now, and I'd love your feedback, especially on the following:<p>- Has anyone tried self-hosting workplace search and/or AI tools, and what was your experience like? - Any concerns with the Postgres-only approach at larger scales?<p>Happy to answer any questions!<p>The code: <a href="https://github.com/getomnico/omni" rel="nofollow">https://github.com/getomnico/omni</a> (Apache 2.0 licensed)

Show HN: Logira – eBPF runtime auditing for AI agent runs
Hacker News (score: 16)Show HN: Logira – eBPF runtime auditing for AI agent runs I started using Claude Code (claude --dangerously-skip-permissions) and Codex (codex --yolo) and realized I had no reliable way to know what they actually did. The agent's own output tells you a story, but it's the agent's story.<p>logira records exec, file, and network events at the OS level via eBPF, scoped per run. Events are saved locally in JSONL and SQLite. It ships with default detection rules for credential access, persistence changes, suspicious exec patterns, and more. Observe-only – it never blocks.<p><a href="https://github.com/melonattacker/logira" rel="nofollow">https://github.com/melonattacker/logira</a>

Show HN: I built a tool that turns any API into a CLI for agents
Show HN (score: 5)Show HN: I built a tool that turns any API into a CLI for agents TLDR; I built a tool that turns any API into a CLI designed for ai agents<p>---<p>Got tired of dealing with bloated context windows from MCP servers and skills that stuff entire API docs into the agent's context<p>CLIs fix this, agents run a single command to self-discover everything an API has to offer<p>So, built a tool to generate them for any api. All CLIs are written in Go, fast and lightweight, no dependencies<p>Help text (via the --help flag) is the killer feature: all context for each command/endpoint/parameter is extracted directly from the user-facing API docs and enhanced with llms. It's bundled directly with the CLI and agents fetch only what they need at runtime. No context overhead, no fumbled API calls.<p>Most APIs don't have a CLI yet. Can have Opus one-shot simple ones, but building a great one with cross-platform binaries, install scripts, detailed help text, and auto-updates takes time and is frustrating to repeat for every API. Maintaining it the API grows is a headache<p>Give InstantCLI any API docs url and it generates a production-ready CLI in minutes. It includes binaries + install scripts for all platforms, auto-updates as your API changes, docs-enhanced help text designed for agents, and hosting
