“The sampling rate, sample rate, or sampling frequency defines the number of samples per second (or per other unit) taken from a continuous signal to make a discrete signal. For time-domain signals, it can be measured in hertz (Hz). The inverse of the sampling frequency is the sampling period or sampling interval, which is the time between samples.”
“In digital audio, common sampling rates are:
- 8,000 Hz – telephone, adequate for human speech
- 11,025 Hz
- 22,050 Hz – radio
- 32,000 Hz – miniDV digital video camcorder, DAT (LP mode)
- 44,100 Hz – audio CD, also most commonly used with MPEG-1 audio (VCD, SVCD, MP3)
- 47,250 Hz – world’s first commercial PCM sound recorder by Nippon Columbia (Denon)
- 48,000 Hz – digital sound used for miniDV, digital TV, DVD, DAT, films and professional audio
- 50,000 Hz – first commercial digital audio recorders from the late 70’s from 3M and Soundstream
- 50,400 Hz – sampling rate used by the Mitsubishi X-80 digital audio recorder
- 96,000 or 192,000 Hz – DVD-Audio, some LPCM DVD tracks, BD-ROM (Blu-ray Disc) audio tracks, and HD-DVD (High-Definition DVD) audio tracks
- 2.8224 MHz – SACD, 1-bit sigma-delta modulation process known as Direct Stream Digital, co-developed by Sony and Philips”
