At the heart of our audio experiences lie audio codecs—algorithms designed to compress and decompress audio data, making it easier to store and transmit. These codecs balance reducing file size with maintaining sound quality, a crucial task in an era where digital audio pervades every corner of our lives.

Traditional codecs, though effective, have limitations. They often rely on lossy compression, which discards certain audio information to shrink file sizes. This process, while efficient, can degrade sound quality, resulting in a noticeable loss of fidelity, particularly for high-resolution audio.

AI-powered audio codecs are redefining this landscape. Leveraging Generative AI, these advanced codecs can reconstruct high-fidelity audio from compressed files. They analyse patterns in the audio data, intelligently filling in gaps left by traditional compression methods. This not only preserves the integrity of the sound but often enhances it, producing audio that closely matches or even exceeds the original quality despite reduced file sizes.

Use Cases:

Streaming Revolution

By delivering high-quality audio with significantly lower bandwidth requirements, AI-enabled audio codecs can enhance the user experience, allowing platforms to stream crisp, clear music and soundtracks even under bandwidth constraints.

For example, an AI codec can dynamically adjust the quality to ensure seamless playback without buffering, making high-fidelity streaming accessible to a wider audience.

Preserving Audio History

AI is also pivotal in restoring and enhancing older audio recordings. Historical speeches, classical music, and vintage radio shows often suffer from poor quality due to age and deterioration.

AI codecs can analyse and repair these recordings, removing noise and artefacts, and breathing new life into audio treasures from the past, ensuring that future generations can enjoy them with remarkable clarity.

GPU Acceleration

The integration of GPU acceleration is crucial in AI audio processing. GPUs boost the performance of AI algorithms, enabling real-time audio encoding and decoding.
