Korkearesoluutioäänellä

Korkearesoluutioäänellä, often translated as high-resolution audio or high-res audio, refers to audio formats that offer a higher fidelity than standard compact disc (CD) quality. This typically means that the audio is recorded, encoded, and played back using a higher sampling rate and/or bit depth than the CD standard of 44.1 kHz sampling rate and 16-bit depth.

Higher sampling rates capture more sound information per second, while a greater bit depth allows for a wider dynamic range and a more nuanced representation of the music's quietest and loudest passages. For example, common high-resolution formats include 96 kHz/24-bit or 192 kHz/24-bit audio.

The primary benefit attributed to high-resolution audio is a perceived improvement in sound quality, offering greater detail, clarity, and a more immersive listening experience. However, the audibility of these differences can be subjective and may depend on factors such as the listener's hearing acuity, the quality of their audio equipment (headphones, speakers, digital-to-analog converters), and the original recording itself.

While high-resolution audio files are larger than standard MP3 or CD-quality files, making them more demanding on storage space and bandwidth, their availability has increased with the growth of digital music distribution platforms. Various audio codecs, such as FLAC (Free Lossless Audio Codec) and ALAC (Apple Lossless Audio Codec), are commonly used for lossless compression of high-resolution audio, preserving all the original audio data.
