A lightweight module that parses AIFF information data from a AIFF file into a Javascript Object. Basically retrieves file and header meta data information from a AIFF file. Now with support for AIFC files
- Determining the validity of a .aif file
- Detecting the bit depth / bit rate / bits per sample of a .aif file
- Detecting the Sample Rate of a .aif file
- Detecting the number of channels in a .aif file
- Retrieving the file information, including file size, created date etc
npm install aiff-file-info --save
var wavFileInfo = require('aiff-file-info');
wavFileInfo.infoByFilename('./test.aif', function(err, info){
if (err) throw err;
console.log(info);
});{ header:
