Abstract: A method is provided for automatic digital audio mixing of at least two digital audio files. The method comprises reading samples from the digital audio files, processing the samples to determine a scale factor for each of the files, applying the scale factors to the samples of each of their corresponding files, and summing the scaled samples to create a single digital audio output file.

Abstract: A method is provided for synchronizing an audio capture program with a streamed audio file. The method comprises receiving at least one selection request from a user connected to a server device, the transmission of a program from the server device to the user client device, the streaming of digital audio data from the server device to the client device, and the detection of state changes associated with an audio stream player disposed within the client device. The transmitted program prepares an audio capture program on the client device in response to state changes associated with the audio stream player and initiates audio capture at a fixed time interval from when the playback state change is detected.
