La idea nació porque otra app empezó a llenarse de versiones que no son las originales.","fuente":"hackernews","fuenteNombre":"Hacker News","color":"#ff6600","autor":"dsmurrell","url":"https://github.com/dsmurrell/onkey","imagen":"/hoy/portada/7502ffe393ce17ad","tema":"tecnologia","subtemas":["inteligencia artificial","aplicaciones","música","canto","programación"],"entidades":["Claude Code","Spotify","Python"],"formato":"dato","entretenimiento":false,"pubTs":"2026-10-22T14:04:44.000Z","indexTs":"2026-10-23T21:12:51.331Z","hash":"f9ee388cecac73202a40c142ecabb41dea84cfe96c23263a6a799253b840c5be","tsa":{"time":"Oct 23 21:13:15 2026 GMT","provider":"freetsa.org","sobre":"sello"},"stats":{"views":0,"likes":0,"clicks":0,"dwell":0},"tipo":"normal","registro":"hallazgo","porQueImporta":"Muestra cómo un problema cotidiano, como practicar canto sin un profesor al lado, puede resolverse con herramientas que hoy cualquiera puede usar sin saber programar.

This is because I’ve been using a singing app (won’t name it here) that scores me on my pitch and timing throughout the song so that I can improve. Lately however, the app I’ve been using has flooded their song list with songs that aren’t originals. I didn’t like this at all as for me, it’s easier to try to improve when you’re singing along to the original. So, I asked an agent (Claude Code) if it could write some code to listen to Spotify and also listen to me and see if it could detect both pitches and score me. It impressed me by writing some Python and showing me my pitch in the terminal!
