Features
Using a hybrid synthesizer core that comes standard in most electronic musical instruments, we have created a line-up of products to optimize peripherals for each target market.
Automotive, Home Appliance
These products create high quality operation sounds and warning sounds for use in automotive and home appliances.
With a built-in hardware sequencer, there is less load placed on the host CPU when playing high-quality sound content.
Built-in applications help skillful sound engineers create optimal sound content.

Mobile
Yamaha sound-source products for mobile phones have FM and PCM sound sources built-in to reproduce the sound effects of ring-tones and game applications.
They also have built-in DSP to perform a variety of signal processing functions, such as audio decoding and sound enhancement, for playing music.
The DSP is programmable, with program firmware downloaded from the host, enabling a range of processing such as voice quality enhancement.
