What is BPM Finder Agent Skill?
The BPM Finder skill is a specialized utility designed to handle practical tempo-related tasks directly within your coding environment. As a key component of the Openclaw Skills library, it enables developers to estimate beats per minute from manual tap sequences, convert tempo into millisecond values for production, and analyze local audio files using command-line scripts. It provides a lightweight alternative to full-scale web applications for quick musical calculations.
This skill is particularly effective for users who need immediate feedback on track speed without leaving their IDE. By integrating Openclaw Skills into your development process, you gain access to powerful CLI-based logic that handles tempo normalization and audio processing via standard tools like ffmpeg.
BPM Finder Agent Skill Use Cases
- Estimating the BPM of a song using manual tap intervals or timestamps.
- Performing local audio file analysis to determine tempo and analysis confidence.
- Converting BPM to milliseconds per beat or bar for precise music production timing.
- Normalizing half-time or double-time readings into a standard 70-180 BPM range.
- Deciding when to route complex batch analysis tasks to a browser-based interface.
How BPM Finder Agent Skill Works
- The agent classifies the incoming request to determine if it requires math, CLI script execution, or external routing.
- For manual input, the agent processes tap arrays or timestamps through the bundled scripts/tap-tempo.js utility.
- For file-based requests, it utilizes the CLI to analyze local audio paths and extract metadata like beat offset and duration.
- It applies normalization logic to ensure the reported BPM fits within practical musical ranges.
- The final output is delivered with clear metrics including confidence scores and analysis windows.
BPM Finder Agent Skill Setup
To get started with this addition to your Openclaw Skills, ensure you have Node.js and ffmpeg installed in your environment. Use the following commands to interact with the local scripts:
# Run tap tempo analysis using intervals
node scripts/tap-tempo.js --intervals 500,502,498,500
# Analyze a local audio file
node scripts/tap-tempo.js --audio-file /path/to/track.mp3 --min-tempo 80 --max-tempo 160
BPM Finder Agent Skill Data Schema & Taxonomy
The skill generates structured data based on the type of analysis performed. These metrics help in maintaining high accuracy within the Openclaw Skills ecosystem.
| Property | Description | Source |
|---|---|---|
| bpm | The calculated beats per minute | All |
| averageIntervalMs | Mean time between detected beats | Taps |
| confidence | Statistical certainty of the analysis | Audio File |
| analysisWindow | The specific audio segment processed | Audio File |
| beatOffsetSeconds | The time offset of the first detected beat | Audio File |
