sampling - Why is telephone audio sampled at 8 kHz ...

When that harmonic content is removed, the audio sounds less natural and pleasing. Higher (than 8Khz) resolution audio is both more intelligible and more pleasing to the ear. Third, Nyquist works within a fixed time domain. If you begin sampling at the exact moment of a peak or trough, then you only need 2x the sample rate to the frequency.

mode and provide the required sample clock on ALRCLK and use ALRCLK as the PLL input. Then they do not need to put another crystal on the board. A The AD1974 PLL will not lock to an Fs below 32 kHz; the part MUST be run in direct mode. For this application, they are correct that 2 MCLK sources are necessary.

I tried to record the sound, I managed to record the sound at a sample rate of 8 kHz. this is my code it works great. But I need more sample rate like 11kHz or 16 kHz, I do not know how I can increase my sample rate to this rate.i use STM32F103C8

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. You can do this off-line with a tool such as SoX, or you can write code that does this on …

First, Import your original sample into iTunes. Then open the preferences dialog and, on the general tab, click “Import Settings…”. From there, select “Custom” from the “Setting” drop-down. Inside the custom settings, select “Stereo Bit Rate” of 16 KHz, a “Sample Rate” of 8 KHz, and Mono “Channels”. Hit Okay in the various dialogs.

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.

The bit depth may be 16-bit, 24-bit, 32-bit, for audio CD 16-bit is preferred. The sample rate is measured in hertz(Hz). According to Nyquist Sampling theorem the sampling frequency to produce the exact original waveform should be double the original frequency of the signal. The human hearing bandwidth is 20Hz-20kHz, the audio sampled can be at ...

Tradition: CDs are in 44.1 kHz; Inertia: audio interfaces are pre-set to 44.1 kHz, and so are onboard sound cards; Cost x benefit: More processing power and disc space are needed to record in a sample rate higher than 44.1 kHz, and the changes are so discreet that a usual ear can’t realize the difference;
