Quantization Bit Rate 16bit.
Why does it sound reasonable even with a low quantization bit?
Quantization Bit Rate 16bit, 24bit.
Let's compare and hear the sounds with different number of quantization bits.
Quantization bit rate in A/D conversion.
G: 1 kHz sine wave(quantization bit number= 16 bits CD quality).
Quantization bit rate of input speech waveform.
Before talking about the number of quantization bits, the recording needs to be in the best condition.
Quantization bit count 16 bits fixed.
So, the lower the volume at the time of recording,the smaller the apparent number of quantization bits.
CD quantization bit number is 16 bits. .
(By the way, I can only hear the sound up to 13kHz)It is the result of compensating for the low quantization bit.
C: Mozart(quantization bit number= 8 bits). .
Because, in most cases, the noise in the roomis louder than the noise caused by low quantization bits(generally called quantization noise).
D: Mozart(quantization bit number= 10 bits). .
If this is a high-resolution sound source, even if the volume is reduced from24 bits by 200 times(46 dB), the quantization bit number for 16 bits is still secured, so the sound does not feel bad.
E: Mozart(quantization bit number= 12 bits). .
For example, if the volume difference between a scene played by an orchestra in fortissimo and a scene played in pianissimo is about 200 times(46 dB), in the case of a 16-bit CD,the pianissimo part will have an apparent quantization bit number of half, 8 It will be a bit. .
Quantization bit rate of speech waveform to be saved in a file.
Input signal quantization bit depth 24-bit or 16-bit switchable.
The quantization bit number is a value that indicates at what stage music source information is expressed.
Even if the number of quantization bits is reduced, the basic sound itself does not change.
For example, if the quantization bit number is 8 bits, it is possible to represent a number between -128 and +127 in binary, and if it is 16 bits, it is possible to represent a value between -32768 and +32767. I can do it.
Even if there is an 8-bit quantization bit rate, if the volume is set to 25%, the apparent 6-bit quantization bit rate will result.
G: Mozart(quantization bit number= 16 bits CD quality).
As the number of quantization bits decreases, a spectrum appears on the higher tone(higher frequency) side.
As the number of quantization bits increases, the jerky waveform becomes smoother and closer to the original sound.
Since the apparent number of quantization bits decreases at a very low volume, a high-resolution sound source with a large number of quantization bits is by far the most advantageous.
Bit quantization, RGB each 8 bit total 24bit output with mini camera link.
