... point was detected as tonal. Since the bird database contains bird sounds of various character, and there is no label information indicating which part of the signal is of a tonal character, we adopted ... evaluation of the detection of bird tonal regions at the spectral-level as a function of the local SNR. The local SNR for a given frequency point was calcula...
