FAQ
After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.
Example:
Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories.
In this case some credentials are needed to access such packages.

- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Informations about the package bpm-finder
BPM Finder for PHP
bpmfinder/bpm-finder is a lightweight PHP library for tap tempo analysis, PCM WAV audio-file BPM estimation, BPM conversion, and practical tempo-range helpers. It is maintained by BPM Finder, the online tool for fast and accurate BPM detection.
Why this package exists
If you are building music tooling, DJ utilities, playlist workflows, or internal tempo features, you often need a few reliable primitives:
- Calculate BPM from user taps
- Estimate BPM from uncompressed WAV audio files
- Convert BPM to milliseconds per beat or bar
- Normalize half-time and double-time readings into a practical range
This package keeps those utilities small, dependency-free, and framework-agnostic.
Installation
Usage
Tap tempo from timestamps
Tap tempo from intervals
BPM and milliseconds conversion
Analyze a WAV audio file
analyzeFile() supports uncompressed PCM WAV files in v1.
Normalize into a practical range
