Unformatted text preview: o Amplitude(quantization) - distance above and below center line o Hertz - number of cycles occurring over the period of one second measured in hertz o AIFF - lossless audio file format developed by Apple o Mp3 - compressed audio format that is a lossy file o Audio frequency - sound that is within the normal range of hearing (20-20,000 cycles) o Digital compression - eliminates frequencies inaudible to the human ear CD 7. Sample rate: 44.1 kilohertz (Nyquist says sampling must be twice as high as the highest frequency sample; when frequencies above the Nyquist limit are introduced into the digital path, aliasing occurs) 8. DSP - Digital signal processing 9. 8x Oversampling - 8 times 44.1 Dithering 10. Minimizes distortion caused by quantization...
