Abstract

A method of operating a computer having an audio device driver (ADD) for driving a soundcard (1), and an application manager (AM) for interfacing the ADD with an audio compression manager (ACM) to facilitate the transfer of uncompressed audio data between the ADD and ACM and for interfacing the ACM with an external data transfer channel (10) to facilitate the transfer of compressed audio data between the ACM and the external data transfer channel (10). The method comprises providing a data transfer manager (DTM) in place of the ACM, the DTM facilitating the transfer of compressed audio data between an external mobile phone (11) and the external data transmission channel (10) via the AM whilst generating dummy control and uncompressed audio data for use by the AM in interfacing with the ADD.
