Abstract
An acoustic processing apparatus and an audio adjusting method for the acoustic processing apparatus are provided. The acoustic processing apparatus is electrically connected with a microphone and a speaker. The acoustic processing apparatus includes an input unit, a storing unit, a computing unit, an adjusting unit, and an output unit. The audio adjusting method includes steps of: receiving a feedback audio from the microphone, calculating a current residue audio according to the feedback audio, a stored residue audio and an offset parameter, performing a correlation calculation to find out a relationship between the feedback audio and the stored residue audio, selectively modifying the offset parameter according to a result of the correlation calculation, and outputting the current residue audio to the speaker.
