DSP chips promise unprecedented audio
Texas Instruments has announced three new floating-point digital signal processors based on the TMS320C67xT DSP generation.
To ensure rich and realistic instrument sounds for MIDI music playback or MIDI sequencing, the platform includes complete and enhanced MIDI synthesiser functions, capable of managing up to 128 simultaneous voices.
The synthesiser functions are based on proven wavetable synthesis technology, used in many sound cards and music synthesisers.
Simultaneous playback of external digital audio, MIDI wavetable, WAV and MP3 files is supported by the software even if sources are based on different sampling rates.
Additionally, the highly optimised wavetable synthesiser is based on proven SoundFont technology.
This gives the developer numerous options to make tradeoffs on synthesised sound quality versus system cost.
Facilitating easy audio content creation and manipulation, the system is also capable of integrating all audio signals into a mixing matrix where they can be processed by multiple effects processes before being output to the speakers.
The mixing matrix also enables global effects, such as reverb and chorus, to be assigned to individual audio sources.
"Lyrtech's robust software solution leverages the performance of TI's C67x floating point DSP generation to provide developers with flexibility that is just not available in fixed function synthesis chipset solutions", said Louis Chouinard, CTO, Lyrtech.
"With the wavetable sound synthesis and audio streaming solution, audio developers have the complete solution to design differentiated and feature-laden end products".
The sound synthesis and audio streaming solution capitalises on the scalability of TI's C67x floating point DSPs to best meet the performance and reliability demands of developers.
All sound synthesis, audio decoding and effect processing occurs on one C67x device, saving developers valuable board space and design cost.
Additionally, the DSP allows developers to upgrade SoundFonts as application needs evolve.
The platform's software can operate on the C6727 Pro Audio Development Kit and C6713 DSP-based CPA-II development board by Lyrtech, or developers can opt to have the software customised to run on a customer-designed C67x DSP audio board.
TI's TMS320C67x devices are based on the high-performance, advanced very-long-instruction-word (VLIW) architecture developed by TI, making it an ideal processor for multichannel and multifunction audio applications.
"The sound synthesis and audio streaming solution empowers developers to design cutting edge, high-quality audio playback and synthesiser products with greater ease and at reduced cost", said Gerard Andrews, Professional Audio Marketing Manager, TI.
"The combination of Lyrtech's powerful software features and TI's C67x DSP generation processor performance provides the optimal solution for the design challenges faced by audio system developers".
The sound synthesis and audio streaming solution is supported by TI's Code Composer Studio integrated development environment.
Additionally, Lyrtech offers turnkey engineering services for hardware and software solution development.
The sound synthesis and audio streaming solution is available now directly from Lyrtech and currently optimised for TI's TMS320C6713 and TMS320C6727 DSPs.
Various licensing/royalties models are available depending on end-products volume.
