Sound Synthesis and Streaming Audio Solution

High-performance audio solutions based on Texas Instruments DSPs offer developers Benefits the flexibility to design a variety of high-quality sound generation products. These • Differentiate the end product solutions include powerful DSPs that prove to be the most reliable, scalable and high- since sound synthesis quality can be determined by lever- performance offerings for a full range of audio designs. aging application-specific sound font libraries For developers of audio products needing high-quality sound synthesis, Lyrtech’s • Leverage flexible audio software solution based on a TI TMS320C6713 floating point DSP offers complete and content creation since multiple audio formats are enhanced MIDI synthesizer functions based on proven wavetable synthesis technology. supported in addition to the This technology, used by many sound cards and music synthesizers, allows rich and synthesis engine realistic sounding instrument sounds for MIDI music playback or MIDI sequencing. • Reduce overall system cost The software solution also supports playback of .wav and .mp3 files and integrates all and board space by allowing sound synthesis, audio audio signals into a mixing matrix where they can be processed by multiple effects decoding, and effects processes before being output to the speakers. This very flexible software package can processing to occur in easily replace and outperform the functionality found in a variety of fixed function one DSP processor synthesis chipset solutions. • Future proof audio designs by using the programmable DSP to upgrade sound fonts as necessary for a System Example: Audio Streaming and Wavetable Solution given application
