Abstract :
Bird songs and calls have been studied using modern signal processing techniques in both time and frequency domains. The complex modulations of these natural sounds are interpreted by a popular bioacoustic model of avian sound production. High resolution signal processing techniques have been applied to the problem of dual-voice detection within bird sounds. Improved time and frequency analyses of these signals have been achieved
