A Study of the Accuracy and Precision of Quadratic Frequency Interpolation for ENF Estimation

Document Thumbnail

Estimation of ENF (Electric Network Frequency) from digital audio recording is required in order to use the ENF as a criterion for audio authentication. Typically, to obtain an accurate frequency estimate ENF is first coarsely calculated using the Discret
