  • receiving notes parameters;

    receiving an indication of a variable amount to alter a pitch of audio data and a frequency to alter the pitch of audio data, the frequency indicating a period of time over which the pitch of audio data is to be altered by the variable amount;

    receiving a data packet including audio data and audio data notes corresponding to the audio data;

    comparing the notes parameters to the audio data notes corresponding to the audio data to determine if there is a match; and

    responsive to determining that there is a match, modifying a pitch value of the audio data by the variable amount over the period of time associated with the frequency.
