Analyse a recording and find the parts of the song

The author of mager.co recorded 37 seconds of himself on piano and wanted to see if Claude Code could analyse audio. He published a skill on Loooom and pointed the agent at a local MP3. Claude Code installed ffmpeg and librosa on the fly and produced a report with tempo, key, meter and sections such as intro, verse and chorus. Tempo came out near 91 against 104 for the original, but he only needed a useful signal, not precision.

How to do it

  1. Paste the prompt into the tool, and replace the text in brackets with your own.
  2. Read the answer through. Do not send, delete or publish anything until you have seen it yourself.
  3. Check the original before you trust a figure, a name or a date.

Try it with Claude Code

Analyse the audio file [file] and find the tempo, meter, key and where each section starts and ends. Install only the tools you need, and tell me which. Mark every number as an estimate and explain how you got it. Show me the plan and the tools before you install anything. You are done when the report is in [file] with a timeline of the sections and a list of uncertain points.

Replace text in brackets with your own.

  • Set up a family home chat server by phone

    A Hacker News user has a home server running a local language model, with Open WebUI as the interface. The teenager in the house has their own account on the home network. An agent using the same model set up the server and handled the accounts, all driven from the phone through Hermes Agent. He thinks local models are fine for ordinary questions and troubleshooting. It is a comment in a discussion, not a guide.

  • Build a knowledge base from YouTube videos and research papers

    Weijian Zhang runs OpenClaw on its own Mac mini, with an agent he calls Eve. He installed a tool that summarises YouTube videos and the search tool QMD himself, then asked the agent to learn both and build its own knowledge base from the videos. Later he added a tool that trims research papers down, with the output saved as Markdown. He writes that the answers were good, but the post is short and shows few examples.

  • Rename hundreds of scanned letters so they sort by date

    A retiree with no coding experience had long ago scanned hundreds of letters and papers with file names built from initials, day, month, year and page. That gave no chronological order. She asked Codex to plan a rename to year, month and day without doing anything yet, and made a backup first. She ran the change in steps and then on more folders. Otherwise the post is mostly about a dinner app.

  • Get a restaurant menu as a link with clear headings

    A blind user writes in an AppleVis review that he asks Muse for an accessible menu every time he goes to a restaurant. The agent creates a link he can share, where each category is a heading at one level and each dish a heading at the level below. That lets him move quickly with a screen reader. The review is one person's experience, and the menu is only as accurate as the source the agent found.
