For most phonemes, almost all of the energy is contained in the 100 Hz–4 kHz range, allowing a sampling rate of 8 kHz. This is the sampling rate used by nearly all telephony systems, which use the G.711 sampling and quantization specifications.

2021-04-24 · A common audio sample rate for music is 44,100 samples per second. The unit for the sample rate is hertz (Hz). 44,100 samples per second is 44,100 hertz or 44.1 kilohertz (kHz). Telephone networks About Sample Rate. Sample rate, sometimes called sample frequency, is used to define the number of samples carried per second for audio file. The unit of account for measuring it is Hertz which is abbreviated as Hz. The sample rate includes the following types: 8, 11.025, 22.05, 32, 44, 48, 64, 88.2, and 96 kHz. You need to either set your recording parameters at the time that you record the sound sample to 8 bits @ 8 kHz, or, if you can't, or don't have any control over the actual recording process, then you will need to resample the original recording to get it into the format that you need.

For the typical producer, band, or solo artist, a 44.1 kHz sample rate should meet your needs. 88.2 kHz may offer more headroom for higher frequencies and can be down-sampled without loss or aliasing. The choice boiled down to two leap-frame sample rates, 50 kHz and 48 kHz. 50 kHz caused a three-frame periodicity with NTSC video, as opposed to the five-frame periodicity of 48 kHz, but it also caused a three-frame periodicity in 24 Hz and 30 Hz systems. 48 kHz caused leap frames only in NTSC. 48 kHz was readily derived by frequency division from standard input frequencies that are used to derive television frequencies, and it readily synchronized with all video signals.

Actually a single voice signal occupies 8 kHz, not 8 kbps, of bandwidth. Each sample is quantized into 8 bits, yielding a rate of 64 kbps which is used universally. Further reading:

These files are actually vox files and I cannot play them in SOME of my wav players yet I can in others. Per the Nyquist–Shannon sampling theorem, the sampling frequency (8 kHz) must be at least twice the highest component of the voice frequency via appropriate filtering prior to sampling at discrete times (4 kHz) for effective reconstruction of the voice signal.

AD1981 PCB Layout recommendation. For most phonemes, almost all of the energy is contained in the 100 Hz–4 kHz range, allowing a sampling rate of 8 kHz. This is the sampling rate used by nearly all telephony systems, which use the G.711 sampling and quantization specifications. Bit rate is defined as sampling frequency multiplied by bit resolution. For land line telephone, the sampling frequency followed is 8 kHz and bit resolution is 8 bits and hence the bit rate is 64 kbps. G.711 is a narrowband audio codec originally designed for use in telephony that provides toll-quality audio at 64 kbit/s. G.711 passes audio signals in the range of 300–3400 Hz and samples them at the rate of 8,000 samples per second, with the tolerance on that rate of 50 parts per million (ppm).

The sample rate is 44.1 kHz. The number of bit rate for the processor is: 80 · 44.1 103 · 24 ≈ 85 MHz d) The number into analog signals with a resolution of 24 bits and a sampling rate of up to 192 kHz. This enables the HDVD 800 to transmit the entire frequency spectrum of Accuracy: /-2 dB. Resolution: 0,1 dB. Sample rate: 2 times/s. Frequency range: 20 Hz – 8 kHz.
