Usage

Import

AudioMetadata and AudioFormat are the only classes you need to import.

import {AudioMetadata, AudioFormat} from 'audio-metadata';

Get metadata description

This will return an object with the metadata description.

AudioMetadata.getMetadataDescription(AudioFormat.MP3)

Get metadata by file path

If the file is stored locally, the metadata can be read by passing the file path and the format.

Format detection by file extension is not supported.

AudioMetadata.getByPath('test.mp3', AudioFormat.MP3);

Get metadata by file buffer

If the file is stored in memory, the metadata can be read by passing the file buffer and the format.

AudioMetadata.getByBuffer(buffer, AudioFormat.WAV);

Notice

This library is still in development. It is not recommended to use it in production. Issues and pull requests are welcome.
