    Abstract: A system and method for converting a note-based audio object to a Pulse Code Modulated (PCM) audio format is disclosed. An electronic computer device includes a memory containing a note-based audio object and a lookup table, the note-based audio object containing note frequency information. A processor is configured for converting the note-based audio object to a Pulse Code Modulated (PCM) stream having a plurality of sample points, the converting including: generating a PCM value for each sample point based upon the note frequency and the trigonometric function evaluations, selecting an entry from the look-up table based upon the note frequency information, a sampling frequency, and a sample point number, and determining a step size within the look-up table based upon a ratio between the note frequency information and the sampling frequency.

    Abstract: A method of ensuring that data sent to a handheld wireless communications device is written to non-volatile memory is disclosed. In a device, where data is initially written to a first volatile memory and then written to a second volatile memory before being written from the second volatile memory to a non-volatile memory, software code is implemented that causes the writing of the data to non-volatile memory concurrently with the writing of the data to the second volatile memory. The software code may incorporate operating system commands (such as Windows OS).

    Abstract: A system and method for converting a polyphonic note-based audio object to a Pulse Code Modulated (PCM) audio format is disclosed. An electronic communication device includes a memory containing a polyphonic note-based audio object containing at least two notes which overlap in at least some time interval and a lookup table containing trigonometric function evaluations. The polyphonic note-based audio object contains note frequency information. The polyphonic note-based audio object is converted to a PCM stream by generating PCM code words for each sample point in the PCM stream based upon the polyphonic note frequency information. The PCM code words are determined based upon selection of one or more of the trigonometric function evaluations within the look-up table. A speaker outputs audio based upon the PCM formatted stream.
