a digital signal processing (DSP) technique for identifying frequency components of a signal, published by Dr. Gerald Goertzel in 1958. While the general Fast Fourier transform (FFT) algorithm computes evenly across the bandwidth of the incoming signal, the Goertzel algorithm looks at specific, predetermined frequency.
an application for viewing and analysing the contents of music audio files, containing advanced waveform and spectrogram viewers as well as editors for many sorts of audio annotations.
