Abstract
A proxy server transcodes audio data on behalf of a client computer prior to transmitting the audio data to the client computer. In response to a request from the client computer, the proxy server obtains the audio data from a remote server. If the proxy server determines that transcoding is appropriate, the proxy server transcodes the audio data and transmits the transcoded audio data to the client computer. Transcoding can include changing the type of the audio file, compressing the audio data, reducing the number of audio channels, or reducing the data sampling rate. The proxy server determines the extent and type of transcoding based on file formats that the client computer can process, the size of the requested audio file, the memory capacity of the client computer, the bandwidth of the connection between the proxy server and the client computer, and the desired level of audio quality.
