Package Exports
- mp3-duration
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (mp3-duration) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme

Calculate duration of an MP3
Install
$ npm install --save mp3-durationUsage
var mp3Duration = require('mp3-duration');

});API
mp3Duration(filePathOrBuffer [, cbrEstimate] [, callback])
filePathOrBuffer
Type: string | Buffer
Path to the file or a buffer with the file's contents
cbrEstimate
Defaults to false. When set to true, will estimate the length of a
constant-bitrate mp3. This speeds up the calculation a lot but isn't
guaranteed to be accurate.
callback(error, duration)
Type: function
Callback to be called once duration is calculated. It's also possible to
instead use the returned Promise. duration is the duration of the
mp3 in ms.
Return value
mp3Duration returns a Promise that resolves to the duration of the mp3 in ms or rejects with some error.
