High-resolution audio (high-definition audio or HD audio) is a term for audio files with greater than 44.1 kHz sample rate or higher than 16-bit audio bit depth. It commonly refers to 96 or 192 kHz sample rates.
5 Φεβ 2024 · In its simplest terms, hi-res audio tends to refer to music files that have a higher bit depth and/or sampling frequency than CD, which is specified at 16-bit/44.1kHz. This definition of 'CD quality' is now commonly referred to as 'lossless', too.
In simple terms, high-resolution audio is digital audio with a higher sampling rate and bit depth than standard CD-quality audio. That means it captures more detail and nuance in the sound, resulting in a more accurate and lifelike representation of the original performance. So why does this matter?
20 Οκτ 2023 · The definition of hi-res audio states that any music file recorded with a sample rate and bit depth higher than 44.1kHz/16-bit is considered high definition (HD) audio. Image from Sony. In this article, we will cover the fundamentals of sample rate and bit depth along with their impact on perceived audio quality.
23 Οκτ 2024 · A 24-bit/96kHz high-res music file, for example, is about three times bigger than a CD-quality file of the same music track. 32-bit/384kHz files are dramatically larger than CD-sized files. Some wireless systems don't have the bandwidth to stream such large files and may down-convert them to a lower resolution for streaming.
3 Φεβ 2024 · The main question. The primary question is not "is there an audible difference between 44.1kHz and 96 kHz sampling rates". It is a secondary question. The real question is about the limits: "do the limits of human hearing exceed the limits of 16-bit and 44.1 kHz?".
13 Αυγ 2024 · With enhancements like dithering, 16-bit audio can “merely” resolve the aforementioned mosquito next to a 120dB jet engine takeoff. Still dramatic overkill. This is what a 24-bit music file looks like before any data is removed. Frequency is the Y-axis, time is the X axis, and intensity is color.
