What is upsampling method?

Upsampling or Oversampling refers to the technique to create artificial or duplicate data points or of the minority class sample to balance the class label. There are various oversampling techniques that can be used to create artificial data points.

What is the purpose of upsampling?

The purpose of Upsampling is to manipulate a signal in order to artificially increase the sampling rate.

Does upsampling improve sound quality?

When we upsample a 44.1kHz 16-bit file to a higher rate and depth, like 96kHz 24 bits, we typically get better sound quality.

Is upsampling the same as oversampling?

Basics of Sampling - Oversampling and Upsampling

When practically implemented though, oversampling refers to using a higher sampling rate than needed to run the A/D or D/A converter thus increasing the rate of the signal. Upsampling is on the other hand a rate conversion from one rate to another arbitrary rate.
