Äänitöötlusülesanded, or audio processing tasks, refer to a range of operations performed on digital audio signals. These tasks are fundamental to many applications, including music production, speech recognition, audio forensics, and telecommunications. The primary goal of audio processing is often to modify, enhance, analyze, or extract information from sound.

Common audio processing tasks include noise reduction, which aims to remove unwanted background sounds from a recording. Another significant task is audio equalization, which adjusts the balance of different frequencies within a signal to shape its tonal character. Audio compression techniques are used to reduce the file size of audio data, either losslessly or with some loss of quality, making storage and transmission more efficient.

Speech processing is a specialized area that includes tasks like speech synthesis, where text is converted into audible speech, and speech recognition, which converts spoken language into text. Audio segmentation involves dividing an audio stream into meaningful segments, such as separating speech from music or identifying different speakers. Feature extraction is another crucial task, where relevant characteristics of the audio signal are identified and quantified for further analysis, such as identifying the tempo of music or the emotional tone of speech. These tasks collectively enable a wide array of sophisticated audio technologies.
