Abstract

AudioSeal introduces a novel audio watermarking technique using localized watermarking and a novel perceptual loss. The method jointly trains two components:

1. Generator: Embeds an imperceptible watermark into audio
2. Detector: Identifies watermark fragments in long or edited audio files

Key Innovations

Localized Watermarking

AudioSeal performs watermarking at the sample level (1/16,000 of a second), enabling precise detection even in heavily edited audio. This localized approach allows identification of which specific segments of audio contain watermarks, making it robust against:

• Audio splicing and editing
• Concatenation with non-watermarked audio
• Partial audio extraction

The model works well with multiple sampling rates including 16kHz, 24kHz, 44.1kHz, and 48kHz.

Perceptual Quality

AudioSeal uses a novel perceptual loss function that ensures watermarks remain imperceptible to human listeners while maintaining detectability. The watermarking process:

• Has minimal impact on audio quality
• Preserves the naturalness of speech and music
• Maintains audio fidelity across different content types

Robustness

The model demonstrates state-of-the-art robustness against various audio manipulations:

• Compression: MP3, AAC, Opus at various bitrates
• Re-encoding: Multiple encode-decode cycles
• Noise addition: Background noise, distortion
• Re-sampling: Sample rate conversions
• Speed changes: Time stretching and compression
• Filtering: Low-pass, high-pass, band-pass filters

Detection Speed

AudioSeal achieves detection speeds two orders of magnitude faster than existing models through:

• Single-pass detection architecture
• Efficient neural network design
• Optimized inference pipeline
• Real-time processing capabilities

This makes AudioSeal ideal for large-scale and real-time applications where millions of audio files need to be processed.
