Oki started shipping samples of the ML26121, which the company claimed as the industry's smallest 16bit stereo audio codec LSI.

The ML26121 is intended for audio recording and playback for portable devices. The device measures 2.96mm x 2.96mm by combining Oki's analog circuit design for ultrasmall size and wafer-level chip-size packaging.

To maximize the sound quality of stereo microphones used in portable equipment, Oki implemented several advanced technologies in the LSI, such as sound effect technologies that enable natural playback of low-pitch sounds, in addition to a wind-noise-reduction and notch filters included in conventional monaural codec LSIs.

The ML26121 also includes several new technologies such as 3D surround to enable realistic stereo sound even when microphones are closely laid out, and LoudSound technology to output loud and high-quality sound even when using a very small speaker.
