An audio codec is a device or software algorithm designed to encode and decode digital audio signals, enabling efficient storage, transmission, and playback of sound. By compressing audio data to reduce file size while preserving quality, codecs support a wide range of applications—from music streaming and voice calls to professional audio production and embedded systems. They can be lossless, retaining every detail of the original sound, or lossy, optimizing for minimal file size with acceptable quality trade-offs. Modern audio codecs also incorporate features such as noise suppression, echo cancellation, and advanced error correction, making them essential for delivering clear and reliable audio across consumer electronics, communication devices, and multimedia platforms.
