ljudprov

Ljudprov is a Swedish term meaning "sound sample" or "audio sample." It refers to a short recording intended to illustrate, test, or evaluate sound. Ljudprov are used in various fields, including linguistics, music production, broadcasting, and consumer electronics, to assess timbre, pitch, dynamics, and overall auditory quality.

In linguistics and phonetics, ljudprov are carefully controlled recordings of speech sounds used to study phonemes, vowels, consonants, and prosody. In music and audio production, they serve as reference tracks for calibration, mastering checks, or sample evaluation across playback systems. In telecommunications and codec testing, standardized ljudprov reveal artifacts introduced by compression or transmission.

Common file formats include WAV, AIFF, FLAC, and MP3. Typical sampling rates are 44.1 kHz or 48 kHz, with 16-bit or 24-bit depth. Ljudprov can be mono or stereo, and metadata such as title, speaker, instrument, license, and rights information is often included.

Quality considerations include clear capture in a quiet environment, neutral or representative content, and appropriate loudness normalization. When distributed publicly, licensing and consent must be observed.

Historically, test tones such as sine sweeps and pink noise served as classic ljudprov for calibration. With digital formats, the use of standardized audio samples has broadened, and the term is common in Swedish media, linguistics, and technical contexts.
