Zotope RX3 Advanced 3 How to use Resampling and Dither Modules


http://www.youtube.com/watch?v=onvnFJoAwVs RX's Resample module allows you to convert an audio file from one sample rate to another. Sample Rate Conversion (SRC) is a necessary process when converting material from one sampling rate (such as studio quality 192kHz) to another rate (such as CD quality 44.1kHz). It is common to record and edit in high sampling rates since higher rates allow higher frequencies to be represented. For example, a 192kHz audio sample can represent frequencies up to 96kHz whereas a 44.1kHz audio sample can only represent frequencies up to 22.05kHz, also known as the Nyquist frequency. When reducing the sampling rate, or downsampling, it is crucial to remove the frequencies that cannot be represented at the lower sampling rate. Leaving frequencies above this point causes aliasing. Aliasing can be heard as the frequencies in an inaudible range are shifted into an audible range causing distortion and noise. With iZotope SRC's steep low-pass filter, users can completely avoid the common aliasing artifacts while maintaining the maximum frequency content. Dither Module The Dither module applies iZotope's MBIT+ dithering technology to improve the quality of your audio files when you are converting to 24, 20, 16, 12, or 8 bits. Dithering takes control of the quantization noise that happens when converting between bit depths. MBIT+ uses psychoacoustic methods to distribute dithering noise into less audible ranges. The result is a more pleasing sound and smoother fades.
