Intrasonics SDK

Intrasonics SDK is a Nodejs wrapper sdk to assist you with command line encoding software of intrasonics

• The Intrasonics AV encoder allows users to insert codewords into media (audio/video) files. The user can specify which codewords they wish to insert and at what point in time within the media file they should be inserted.
• The encoder is available on Windows, Mac, or Linux. It uses a command/terminal window and the user may specify codewords and timings using either a configuration file or by typing commands at a prompt.
• Magic

Installation

npm install intrasonics-sdk

Tech

Intrasonics SDK uses a number of open source projects to work properly:

• npm - Essential JavaScript development tools that help you go to market faster and build powerful applications using modern open source code.
• node.js - evented I/O for the backend
• intrasonics - Intrasonics' audio watermarking technology uses sound to help you harness consumer interest when it matters most.

Requirements

Intrasonics SDK uses resources provided by intrasonics:

• encoding software - A Folder contains files AVFileDecoder ffmpeg ffprobe files provided by intrasonic for encoding
• encoder token - Encoder token (with .ist suffix) used to get access provided by intrasonics

Encoder Sofware Versions used

• Linux - LinuxAVEncoder_4.2.0
• Mac - OSXAVEncoder_4.2.0
• Windows - WindowsAVEncoder_1.0.7

Example

const IntrasonicsSDK = require('intrasonics-sdk');

let intrasonicsSDK;
try {
  intrasonicsSDK = new IntrasonicsSDK({ softwareFolder: 'intrasonics', tokenPath: 'intrasonics/intrasonics-token.ist' });
  intrasonicsSDK.encode({
    filePath: 'input-files/audio.mp3',
    codeword: '10001',
    outputPath: 'encoded-files/audio_encoded.mp3',
    eventEngine: true
  })
    .then((stdout) => {
      console.log(stdout);
    }, (err) => {
      console.error(err);
    })
} catch (err) {
  console.error(err);
}

await intrasonicsSDK.encode({filePath, codeword, [outputPath], [eventEngine], [time]})

filePath (string) [file path or file name]

• file name or file path of a audio/video file to be encoded

codeword (string)

• watermarkId/trackId that will be encoded in audio/video file

outputPath (string) [optional]
