pcm-format

Format PCM data stream

Installing

npm install pcm-format

Example usage

var PcmFormatTransform = require('pcm-format');
 
process.stdin
.pipe(new PcmFormatTransform(
    { float: true }, // in format
    { float: false, signed: true, bitDepth: 16, byteOrder: 'BE' } // out format
))
.pipe(process.stdout);
 
// In and out format objects support all the same parameters
// (float, signed, bitDepth, byteOrder),
// and all other properties are ignored.
 
// 'byteOrder' is either 'LE' or 'BE', a la os.endianness(),
// and defaults to the OS's endianness. It can be ignored if bitDepth is 8.
// If 'float' is true, 'signed' is always true and 'bitDepth' is always 32.
 
// The format objects are modeled after 'TooTallNate/node-speaker' and similar modules.
