Audio processing in multi-OS devices having multiple audio inputs
An apparatus is provided to improve audio processing. The apparatus includes a processor configured to execute a process based on an operating system (OS), and an audio signal processing part to support inputs of a first audio signal which is associated with the OS and a second audio signal which is inputted via a second input unit that is different from the first input unit. The audio signal processing part has a first processing mode and a second processing mode in which the audio signal processing part outputs an audio signal based only on the second audio signal. The apparatus also includes a setting part configured to set the audio signal processing part to the first processing mode when the process based on the OS is executed by the processor and to the second processing mode when the process based on the OS is at least partially limited.
