go-media chromaprint bindings

This package provides bindings for chromaprint audio fingerprinting.

This package is part of a wider project, github.com/mutablelogic/go-media. Please see the module documentation for more information.

Building

In order to use this package, you will need to install the chromaprint libraries. On Darwin (Mac) with Homebrew installed:

[zsh] brew install chromaprint
[zsh] go get git@github.com:djthorpe/go-media.git
[zsh] cd go-media/sys/chromaprint

For Linux Debian,

[bash] sudo apt install libchromaprint-dev
[zsh] go get git@github.com:djthorpe/go-media.git
[zsh] cd go-media/sys/chromaprint

For more information:

• API Documentation Sources: https://github.com/acoustid/chromaprint
• Web Service: https://acoustid.org/webservice

This package provides low-level library bindings. There is also a client library for the web service.
