• quantization
• quantization level
• linear/uniform quantization
• $SQNR(signal to quantization noise ratio) = 10log(\frac{\sigma_x^2}{\sigma_e^2}) dB$ where $\sigma_e^2 = \int_{-\infty}^{\infty}ep_e(e)de$ and $\sigma_x^2$ is the variance
• ${DR(dynamic_range)}_{uniform}$ = loudest amplitude / softest amplitude
• $DR_{sinusoid} = SQNR_{full_scale_sinusoid}$ = signal power of a full scale sinusoid / the signal power of a small sinusoidal
• CD format
• 16 bit linear quantization
• DR = 16*6 = 96(dB)
• nonlinear/logarithmic quantization(the sample is quantized linearly and then compressed according to the nonlinear compression rule)
• A-law
• Europe
• compresses a 12-bit linearly quantized speech sample to an 8-bit word
• ${\mu}-law$
• North America
• compresses a 13 to 14-bit linearly quantized speech sample to an 8-bit word
• API
