ColloAI Media Processor is a JavaScript library for real-time AI-powered video and audio enhancement in web applications.

• Real-time video effects: background blur, color correction, low-light boost
• AI audio processing: noise suppression, automatic gain control, voice focus
• Live analytics and smart recording

npm install colloai-media-processor

import { MediaProcessor } from 'colloai-media-processor';

const processor = new MediaProcessor();
processor.enableVideoEffects({ blur: true, colorCorrection: true });
processor.enableAudioEffects({ noiseSuppression: true });

// Attach to a video/audio stream
processor.attachToStream(mediaStream);

• MediaProcessor: Main class for managing video/audio enhancements.
• enableVideoEffects(options): Enable/disable video effects (blur, color correction, etc.).
• enableAudioEffects(options): Enable/disable audio effects (noise suppression, AGC, etc.).
• attachToStream(mediaStream): Attach processor to a MediaStream.
• detach(): Remove all effects and detach from stream.

// Enable background blur and noise suppression
const processor = new MediaProcessor();
processor.enableVideoEffects({ blur: true });
processor.enableAudioEffects({ noiseSuppression: true });

MIT

• Noise Suppression: Filter out background noise (keyboard clicks, fan noise, room echo)
• Automatic Gain Control (AGC): Dynamic microphone volume adjustment
• Voice Focus: Prioritize human speech over background sounds

• Color Correction: Real time color adjustment and lighting compensation
• Low Light Compensation: Enhance visibility in poor lighting conditions
• Background Blurring: Professional background blur effect
• Background Replacement: Virtual background' support

new MediaProcessor(config)

• process(stream): Process a MediaStream and return enhanced stream
• updateConfig(newConfig): Update processor configuration
• destroy(): Clean up resources

processor.on('processing', (event) => {
  console.log('Processing frame:', event.timestamp);
});

processor.on('error', (error) => {
  console.error('Processing error:', error);
});
