Oversampling can make it easier to realize analog anti-aliasing filters. Furthermore, while oversampling can reduce quantization error and non-linearity, it cannot eliminate these entirely. Many modern converters use oversampling and a multi-bit design. The level of pixel oversampling is highest when zoom is not used. COSMOS solves the inverse problem by oversampling from multiple orientations. Another key aspect given by oversampling is the speed/resolution tradeoff. It means that people can make trade off between spatial oversampling and temporal oversampling. The onboard Yamaha YMZ263-F also performs 2x oversampling, which would affect the OPL3 output slightly. These two types of oversampling are sometimes called "spatial" and "time" respectively. Improved resolution can be obtained by several techniques such as oversampling/averaging. If it is allowed to have temporal oversampling, i.e. In oversampling, audio samples are acquired at a multiple of the desired sample rate. Other methods include the use of a delay-locked loop and oversampling of the data stream. It gradually decreases until the maximum zoom is hit, where there is no oversampling. It is possible to reduce this error by oversampling/averaging techniques.
