| Nested Object | An object that lies within another object - see also Child Object. |
| Noise Gate | An effect created in the Expander effect plug-in that removes sounds from the output signal almost completely. A noise gate is created by setting a high expander ratio (over 10:1) that closes the gate for sounds whose gain has been reduced to this extent. |
| Nyquist Frequency | The highest audio frequency that can be accurately sampled, equivalent to one-half of the sampling rate. The Nyquist sampling theorem showed that the sampling rate must be at least twice the highest frequency present in the sample in order to accurately reconstruct the original signal. |
