Quantization And Transmission Of Audio in MULTIMEDIA ...

Using uniform quantization without companding, the minimum sample size we could get away with would likely be about 12 bits. Hence, for mono speech transmission the bitrate would be 240 kbps. With companding, we can safely reduce the sample size to 8 bits with the same perceived level of quality and thus reduce the bitrate to 160 kbps.

Audio CD bitrate is always 1,411 kilobits per second (Kbps). The MP3 format can range from around 96 to 320Kbps, and streaming services like Spotify range from around 96 to 160Kbps. High bitrates appeal to audiophiles, but they are not always better. Keep in mind how your digital audio is going to have to contend with bottlenecks.
Understanding Audio Quality: Bit Rate, Sample Rate ...

Bit Rate refers to the audio quality of the stream. It is measured in Kilobitspersec (kbps or k). Bit rate is no of bits (data) encoded per second or the no. of bits transmitted or received per second. Higher the bit rate with more sampling rate, requires high bandwidth and produces good audio quality.

The most common audio bit depths are 16-bit, 24-bit, and 32-bit. Each is a binary term, representing a number of possible values. Systems of higher audio bit depths are able to express more possible values: 16-bit: 65,536 values. 24-bit: 16,777,216 values. 32-bit: 4,294,967,296 values.

We can convert the 16-bit audio down to other quantization levels to see and hear how quantization affects quality. In [4]: # Convert to float audio_data_float = audio_data_16bit / 2 ** 16 # 16 bit audio # With 8-bit audio, ...

A bit depth of 16-bit for a sample rate of 44.1kHz is enough to reproduce the audible frequency and dynamic range for the average person, which is why it became the standard CD format. Should You Always Record in 192kHz/24-bit? Although there are no limits to sample rate and bit depth, 192kHz/24-bit is the gold standard for hi-res audio.
