Most digital audio has a sampling rate of 44.1kHz, which is also the sampling rate for audio CDs. This means that the audio is sampled 44,100 times per second during recording. When the audio is played, the hardware then reconstructs the sound 44,100 times per second. Those individual samples vary in the amount of information they have.

The most common audio sample rate you’ll see is 44.1 kHz, or 44,100 samples per second. This is the standard for most consumer audio, used for formats like CDs. This is not an arbitrary number. Humans can hear frequencies between 20 Hz and 20 kHz.

Audio Data Rate = Bit Depth x Sampling Frequency. In the example below the data rate of a single 16-bit/48 kHz audio stream is computed in mebibytes per minute. Division by 1048576 converts from bits to mebibits. Division by 8 converts from mebibits to mebibytes; multiply by 60 converts seconds to minutes.

MP3 Audio Bitrate The highest quality MP3 bitrate is 320 kbps at 16 bit. You can encode MP3s as low as 96 kbps. MP3s use a compression codec that removes frequencies while trying to preserve as much of the original recording as possible. This does result in a reduction in sound quality but also a big reduction in file size.

The higher the bitrate, the more data per second of music. As you’d expect, a higher bitrate creates better quality audio, along with a larger file. Generally speaking, 128 kbps (kilobits per second) is considered the bitrate at which an MP3 begins to exhibit artifacts of data compression.
Sound Quality vs. Data Rate

An 8 kHz sampling rate, with an ADC precision of 8 bits per sample, results in a data rate of 64k bits/sec. This is the brute force data rate for natural sounding speech. Notice that speech requires less than 10% of the data rate of high fidelity music.

sampling_rate = 16k says that this audio was recorded (sampled) with a sampling frequency of 16k. In other words, while recording this file we were capturing 16000 amplitudes every second. Thus, If we want to know the duration of the audio, we can simply divide the number of samples (amplitudes) by the sampling-rate as shown below —

As human hearing range is around 20K Hz, sampling rate of audio files in many libraries are by default set at 22050 per sec. We do have an option of increasing/decreasing it as per the need. Wait —...

For example, PCM audio stored on a compact disk (CD) is sampled at 44,100 samples/second, or 44.1 kHz, and saved as 16-bit signed samples. Other common sample rates are 8 kHz or 16 kHz for telephony-quality voice, 48 kHz for DVD audio, and 96 kHz for high-definition audio.
