Oki Semiconductor Audio Devices are targeted for portable applications, where size is a priority, but where sound quality and loudness are also very important.

These devices provide high-quality audio functions integrated in very small packages and with very low power consumption. Portable devices have constrains in the size of speakers they can embed. Usually, these small speakers can not reproduce sounds with good quality nor enough volume. Oki Semiconductor audio technologies make it possible to output very loud high-quality sound, even when using very small speakers.

Some of the enabler technologies are Oki Semiconductor’s proprietary LoudSound technology, Automatic Level Controllers, Parametric Equalizers, Audio Quality CODECs, embedded power regulators, noise filters, Filterless Class-D Speaker Amplifiers, among others.

LoudSound technology is a digital audio signal processing that makes it possible to improve the sound quality and volume reproduced by very small speakers typical of portable applications.
