Embodiments of the invention disclose a method and a device for forming an adaptive beam, equipment and a storage medium. The method comprises the following steps: acquiring a sound source direction and an audio stage at a current moment; determining a filter weight coefficient, a desired signal and a reference signal at the current moment; calculating according to a regularized adaptive filteringalgorithm or a traditional adaptive filtering algorithm of a cost function to obtain the filter weight coefficient of a next moment, or using the filter weight coefficient of the current moment as the filter weight coefficient of the next moment; and filtering an audio signal of the next moment based on the filter weight coefficient of the current moment. With adoption of a technical solution provided by embodiments of the invention, two adaptive algorithms with different noise suppression performances are combined according to sound source information are combined to obtain different filterweight coefficients for further filtering the audio signal, thereby solving a problem of directional voice damage while ensuring excellent nondirectional noise suppression performance, and improving robustness of the method for forming the adaptive beam.
