A、Quantization bits are the number of samples taken from the acoustic analog signal in one second
B、Quantization bits are the bits of decimal data for each sampling point
C、Quantized bits are the number of bits per sampling point in hexadecimal data
D、Quantization bits are the bits of binary data at each sampling point
喵查答案：Quantization bits are the bits of binary data at each sampling point
Which is right among the following statements about the quantized bits in sound digitization?
-
Generally speaking, the higher the sound quality is required, the higher the quantization level and the lower the sampling frequency is. -
The higher the sampling frequency, the closer the discrete digitized sound wave is to its original waveform. -
Audio files in WAV format do not use compression algorithm, so they have good sound restorability, strong stereoscopic impression and relatively large file capacity. -
MPEG video compression standards include MPEG-1, MPEG-2, MPEG-4, MPEG-7 and MPEG-21.
