The invention provides a symmetric audio acquisition method and device, electronic equipment and a storage medium, and relates to the field of data processing, in particular to the field of voice technologies and deep learning. The specific implementation scheme is as follows: acquiring a to-be-processed original audio; performing phase spectrum offset processing on the original audio to generate a plurality of offset audios with offset phases; and performing waveform symmetry detection on the plurality of offset audios, and obtaining a waveform-symmetric target audio from the plurality of offset audios. According to the invention, based on the phase spectrum offset processing, the original audio is processed into the target audio with the symmetrical waveform, so that the volume consistency of the audio signal is greatly improved, stable training of a deep learning network is facilitated, the error probability of speech synthesis is reduced, and the listening experience of a user is improved.
