Patent AT-E400868-T1: [Translated] CONVERSION FROM NOTE BASED SOUND FORMAT TO PCM BASED SOUND FORMAT
A system and method for converting a note-based audio object to a Pulse Code Modulated (PCM) audio format is disclosed. An electronic communication device (10) includes a memory containing a note-based audio object (60) and lookup table (62) containing trigonometric function evaluations. The note-based audio object (60) contains note frequency information. The note-based audio object (60) is converted to a PCM stream by generating PCM code words for each sample point in the PCM stream based upon the 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 (62). A speaker (34) outputs audio based upon the PCM formatted stream.
