What is DOA music?
DOA is for the direction of array antenna of the radio wave. The angle between the array normal and the direction vector of the plane wave is the Direction of arrival (DOA). The estimated target of DOA gives N snapshots data: X (1)… X (N), using an algorithm to estimate the value of multiple signals’ DOA (θ).
How can I listen to Spotify without using the algorithm?
By default, anyone who follows you on Spotify can see what you’re listening to with Friend Activity. If you don’t want others to know what you’re listening to, you can start a Private Session….Private listening

Which is the best method for peak detection?
A robust method for estimating peak frequency with very high accuracy would be to fit a window transform to the sampled spectral peaks by cross-correlating the whole window transform with the entire spectrum and taking and interpolated peak location in the cross-correlation function as the frequency estimate.
What does a bin mean in peak detection?
A bin represents a frequency interval of Hz, where is the FFT size. Zero-padding increases the number of FFT bins per Hz and thus increases the accuracy of the simple peak detection.
How does peak detection work in the STFT?
Due to the sampled nature of spectra obtained using the STFT, each peak (location and height) found by finding the maximum-magnitude frequency bin is only accurate to within half a bin. A bin represents a frequency interval of Hz, where is the FFT size.
What happens when peak is found in spectrum?
Once an interpolated peak location has been found, the entire local maximum in the spectrum is removed. This allows the same algorithm to be used for the next peak. This peak detection and deletion process is continued until the maximum number of peaks specified by the user is found.
