2. 48,000 Hz - Wikipedia

   en.wikipedia.org/wiki/48,000_Hz

   The DVD format uses the 48 kHz sampling rate, and its doublings. In digital audio, 48,000 Hz (also represented as 48 kHz or DVD Quality) is a common sampling rate. It has become the standard for professional audio and video. 48 kHz is evenly divisible by 24, a common frame rate for media, such as film, unlike 44.1 kHz. [i]

3. High-resolution audio - Wikipedia

   en.wikipedia.org/wiki/High-resolution_audio

   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. However, 44.1 kHz/24-bit, 48 kHz/24-bit and 88.2 kHz/24-bit recordings also exist that are labeled HD audio.

5. 44,100 Hz - Wikipedia

   en.wikipedia.org/wiki/44,100_Hz

   This sample rate has become the standard rate for professional audio. [2] Until recently [ when? ] , sample rate conversion between 44,100 Hz and 48,000 Hz was complicated by the high ratio number between the rates of these as the lowest common denominator of 44,100 and 48,000 is 147:160, but with modern [ vague ] technology this conversion is ...

6. ADAT Lightpipe - Wikipedia

   en.wikipedia.org/wiki/ADAT_Lightpipe

   Lightpipe can carry eight channels of uncompressed digital audio at 24 bit resolution at 48,000 samples or four channels at 96,000 samples per second. Initially used for the transfer of digital audio between ADATs, the protocol was designed with future improvements in mind.

7. Sampling (signal processing) - Wikipedia

   Sampling rate Use 8,000 Hz Telephone and encrypted walkie-talkie, wireless intercom and wireless microphone transmission; adequate for human speech but without sibilance (ess sounds like eff (/s/, /f/)). 11,025 Hz One quarter the sampling rate of audio CDs; used for lower-quality PCM, MPEG audio and for audio analysis of subwoofer bandpasses.

8. Portable Sound Format - Wikipedia

   en.wikipedia.org/wiki/Portable_Sound_Format

   PSF's native sample rate is 44,100 Hz, while PSF2's is 48,000 Hz. Rates may vary from 8,000 Hz to 96,000 Hz. Rates may vary from 8,000 Hz to 96,000 Hz. Both PSF and PSF2 files contain a header which specifies the type of video game system the file contains data for, and an optional set of tags at the end which can give detailed information such ...

9. Sample-rate conversion - Wikipedia

   en.wikipedia.org/wiki/Sample-rate_conversion

   Audio on Compact Disc has a sampling rate of 44.1 kHz; to transfer it to a digital medium that uses 48 kHz, method 1 above can be used with L = 160, M = 147 (since 48000/44100 = 160/147). [5] For the reverse conversion, the values of L and M are swapped.
