MoreThe control for sample rate reduction (a.k.a. "downsampling" or "averaging") is sometimes shown in Hz for a new sample rate, or as a reduction factor. Sample rate reduction is sometimes shown instead as the number of consecutive samples to average together to create a new sample. A value of 20 reduces the sample rate to 1/20 of its original rate.

MoreA crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
