What is High-Resolution Audio?
To understand what high-resolution audio is, let’s first define audio resolution. In audio, resolution refers to the number of bits used to represent a sound wave digitally. The higher the resolution, the more accurately the sound wave can be captured and reproduced.
High-resolution audio furthers this concept by offering a higher sample rate and bit depth than standard CD-quality audio. Sample rate refers to the number of times a sound wave is measured and recorded digitally per second. CD-quality audio has a sample rate of 44.1kHz, meaning the sound wave is estimated and recorded 44,100 times per second.
In comparison, high-resolution audio can have sample rates of up to 384kHz or more, which means that the sound wave is measured and recorded at a much higher frequency.
Bit depth refers to the number of bits used to represent each sample of the sound wave. CD-quality audio has a bit depth of 16 bits, which allows for 65,536 levels of amplitude. High-resolution audio can have bit depths of up to 24 bits, allowing for over 16 million amplitude levels.
That means that high-resolution audio can capture more detail and nuance in the sound, resulting in a more accurate and lifelike representation of the original performance.
High-resolution audio offers a more detailed and accurate representation of a recording than standard CD-quality audio. That can significantly affect the listening experience, especially for music with intricate instrumentation and dynamics.
When comparing high-resolution audio to standard audio, the difference is most noticeable in detail and clarity. With high-resolution audio, you may hear instruments and vocals previously buried in the mix. You may also notice a wider and more spacious soundstage, giving the music a more immersive and lifelike feel.
