High-resolution audio files are digital music formats that offer better sound quality than standard audio files. They contain more detail and a wider range of frequencies, allowing listeners to experience music as it was intended by the artists. Common high-resolution formats include FLAC, ALAC, and DSD. These files typically have higher bit depths and sample rates, which means they capture more information from the original recording. For example, while a standard CD has a sample rate of 44.1 kHz, high-resolution files can go up to 192 kHz or higher, providing a richer listening experience.
