Hi-Res Audio refers to audio files that have a higher resolution than standard CD quality. This means they contain more detail and a wider frequency range, allowing listeners to experience music as it was intended by the artists. Hi-Res Audio files typically have a sample rate of 96 kHz or higher and a bit depth of 24 bits, compared to the 44.1 kHz and 16 bits of CDs. To enjoy Hi-Res Audio, listeners need compatible devices, such as digital audio players or headphones that support high-resolution formats. Popular file formats for Hi-Res Audio include FLAC, ALAC, and DSD, which help preserve the quality of the original recordings.
