What is audio oversampling?

What is oversampling? Simply put, oversampling is processing audio at a higher multiple of the sample rate than you are working at. The sample rate we work at must be at least twice the highest frequency we wish to record or process.

Is oversampling good music?

Simply put, oversampling increases the maximum frequency your processors can handle and increases the accuracy with which the signal is encoded and processed. This makes it a great option for reducing distortion and subtly increasing the clarity of your signal. Get a FREE Mastered Sample of Your Song!

What is the purpose of oversampling?

Oversampling is capable of improving resolution and signal-to-noise ratio, and can be helpful in avoiding aliasing and phase distortion by relaxing anti-aliasing filter performance requirements. A signal is said to be oversampled by a factor of N if it is sampled at N times the Nyquist rate.

How much should you oversample?

Choosing an oversampling rate 2x or more instructs the algorithm to upsample the incoming signal thereby temporarily raising the Nyquist frequency so there are fewer artifacts and reduced aliasing. Higher levels of oversampling results in less aliasing occurring in the audible range.
