Digital Audio Sample Rates: The 48 kHz Question | TV Tech
https://www.tvtechnology.com/opinions/digital-audio-sample-rates-the-48-khz-question
In the U.S., Soundstream and 3M were leaders in digital audio recording, and both had hardware using the 50 kHz sample rate, which of course had generated a considerable quantity of software using that sample rate. 3M had proposed the distribution of 5005, 50 kHz digital audio samples over six video fields for NTSC television. 50 kHz may be derived by …
Will the End of NTSC Be the End of 59.94? | TV Tech
https://www.tvtechnology.com/opinions/will-the-end-of-ntsc-be-the-end-of-5994
The two earliest digital audio recorders both used a 50 kHz sample rate, but 48 kHz became the standard in large part because it bears a better mathematical relationship to NTSC frequencies. A significant advantage of the 59.94 Hz rate is that it permitted the worldwide standardization of the 13.5 MHz digital video sample rate in ITU-R Rec. 601, for both 59.94 Hz …

Explanation of 44.1 kHz CD sampling rate - Columbia University
http://www1.cs.columbia.edu/~hgs/audio/44.1.html
The sampling frequency is chosen somewhat higher than the Nyquist rate since practical filters neede to prevent aliasing have a finite slope. Digital audio tapes (DATs) use a sampling rate of 48 kHz. It has been claimed that thier sampling rate differs from that of CDs to make digital copying from one to the other more difficult. 48 kHz is, in principle, a better rate since it is a multiple of …
Digital Audio Basics: Audio Sample Rate and Bit Depth

Other audio sample rates: 48 kHz, 88.2 kHz, 96 kHz, etc. While 44.1 kHz is an acceptable audio sample rate for consumer audio, there are instances in which higher sample rates are used. Some were introduced during the early days of digital audio when powerful anti-aliasing filters were expensive. Moving the Nyquist frequency even higher allows ...

Audio for film and TV broadcast should always be recorded at 48 kHz or one of its variants, 48.048 kHz and 47.952 kHz. If you have been instructed to shoot at 48.048 kHz or 47.952 kHz, always select the ‘fake’ stamped sample rates of 48.048F or 47.952F respectively unless otherwise instructed by pre-production.

Audio . Channels: Choose whether to present the audio as multichannel surround sound or as stereo. Sample Rate: Choose the audio sample rate for your project (the number of times a signal is measured—or sampled—per second).A higher sample rate produces higher-quality audio and larger file sizes, and a lower sample rate produces lower-quality audio and smaller file sizes.
