Show HN: A browser-based tone generator built with the Web Audio API I built maketonesonline.com — a simple browser-based tone generator to experiment with the Web Audio API. What it does: Generates tones from 20 Hz to 20,000 Hz Supports sine, square, triangle, and sawtooth waveforms Lets you adjust frequency, volume, and left/right stereo pan Includes multi-tone, binaural beat, subwoofer/bass frequency, and sweep tone modes It’s useful for testing speakers, hearing tests, exploring sound design, or just seeing how high a pitch you can still hear. Check it out: https://ift.tt/Ucdjnvt I’d love your thoughts, bug reports, or ideas for improvement! https://ift.tt/AxVnj0U May 20, 2025 at 11:20PM

Launch HN: Stacker (YC S20) – Create Apps from Airtable or Google Sheets https://ift.tt/3i3ZJso

We spent about 2 years building a really powerful and complicated drag-and-drop no-code app builder. It was really awesome, it could create social networks, SaaS, marketplaces – the works. The only problem was: nobody could use it unless they were already a developer! It turned out that even though you weren't technically writing any code… you were still actually programming, still thinking like a developer. Just with a really inefficient set of no-code tools. We (eventually!) realised that non-devs were already building systems anyway; but ...
