stereostandardi

Stereostandardi, or stereo standards, refer to the guidelines and specifications that govern the creation, processing, and reproduction of stereo media. This encompasses two-channel and multi-channel audio formats, loudness normalization, channel balance and crosstalk, encoding and decoding pipelines, and the rendering of depth in stereoscopic video. Rather than a single document, stereo standardization comprises a family of standards developed by international bodies and industry groups to ensure interoperability across devices and platforms.

Various organizations publish stereo standards and recommendations, including ISO/IEC, the ITU, SMPTE, the Audio Engineering Society (AES), and the European Broadcasting Union (EBU). In audio, standards cover PCM formats, metadata handling, and practical aspects of playback in home and professional environments. In video and imaging, standards address stereoscopic depth cues, alignment between left and right images, color consistency, and display compatibility for 3D TVs, VR headsets, and cinema systems.

Standardization of stereo media emerged during the mid-20th century with the availability of compatible hardware and broadcast systems, and has evolved with digital encoding, compression, and immersive technologies. Stereo standards facilitate interoperability, consistent quality, and accessibility, while providing a framework for testing, certification, and market licensing. Adoption and emphasis vary by region and industry segment, reflecting different technical requirements and legacy systems.
