The present invention relates to the field of audio processing technology, and more particularly, to a real-time audio processing method, system, device, and medium. The method including: receiving real-time audio data, and storing the audio data in a buffer, wherein the audio data is stored in a plurality of blocks in the buffer, and each block includes a certain number of sampling points; obtaining displacement data of a user's operation; said reading and playing one of the blocks at the corresponding position in the buffer, based on the speed and acceleration calculated from the displacement data. Achieving interaction between a user and real-time audio, including supporting a game player to perform interaction with real-time audio in a game to complete a scratching sound effect, restoring a mechanical scratching effect, and the transition of the sound effect is delicate and smooth, the hardware performance cost is small.

A method for acquiring a blood flow volume and a blood flow velocity of a coronary artery is provided. The method comprises: acquiring image information of a coronary artery to obtain geometrical feature data of the coronary artery; obtaining, according to the geometrical feature data of the coronary artery, the total volume V of a reference lumen of the coronary artery; and calculating a blood flow volume Q at coronary artery ostia according to the following formula: wherein when the unit of Q is mm/s, and when the unit of V is mm, a value range of K is 5-9.5. A blood flow volume and a blood flow velocity of a coronary artery are obtained by means of image information of the coronary artery. Compared with a method, in the prior art, for estimating a blood flow volume of a coronary artery by means of the size of a cardiac muscle, this method is simpler, and can provide a more accurate boundary condition for image-based hemodynamic calculation.
