Helifailideks

Helifailideks is a term used in Estonian-language discourse to describe a category of digital file formats and metadata conventions designed for audio data. In this usage, helifailideks covers both audio containers and the metadata schemas that accompany recordings, including information such as title, author, license, language, and technical parameters. The word combines heli-, meaning “sound” or “audio,” with failideks, a suffix meaning “for files.”

Characteristics include support for various codecs (lossless and lossy), as well as structured metadata blocks that facilitate search, discovery, and preservation. Formats within the concept typically aim for interoperability and long-term accessibility, preserving essential details like sample rate, bit depth, channel configuration, duration, and copyright.

Origins and usage: Helifailideks is not a formal, internationally ratified standard. It appears mainly in academic, archival, and library contexts as a shorthand to discuss audio-file formats and their accompanying metadata in Estonian-language texts. It is used when comparing different archiving strategies for radio programs, podcasts, field recordings, and sound archives.

Relation to existing formats: In practical terms, common formats such as WAV, FLAC, MP3, and AAC are cited as examples within the helifailideks framework, because they exemplify the kinds of container, codec, and metadata considerations central to the concept.
