The W681512WG is a highly integrated digital stereo audio CODEC (COder/DECoder) designed for digital mobile/portable audio products, such as Digital Multimedia players, digital speakers, and multimedia telephones. It combines the advanced micro-architecture of the digital signal processor (DSP) with the powerful digital encoder (codec), thereby enabling it to provide the highest quality sound, regardless of the size of the audio input. The W681512WG is capable of producing high-quality digital audio with a low power consumption and a low-noise design.

The W681512WG provides accurate decoding/encoding processes. It supports up to 16 bit/48kHz audio levels and also supports 8 bit/48KHz audio levels at a sample rate of 44.1KHz. The W681512WG uses two techniques, the “Digital Cross-over” and the “Adaptive Time-scale Control”, to reduce noise and provide a stable, low-noise sound. The Digital Cross-over eliminates frequency masking, thus enabling the direct output of speakers and eliminating harmonic distortion. Adaptive Time-scale Control is also used to reduce noise, eliminate clipping and result in an accurate high-resolution output.

The W681512WG has an on-chip, 32-bit DSP, which performs all the digital signal processing functions required for stereo audio encoding and decoding. The W681512WG supports a variety of audio codecs, including MPEG1 Layer 3, MPEG2 Layer 3, MPEG4 AAC, Dolby Digital, AC3, True Audio, WMA, AAC+, WMA Lossless, FLAC, and MP3. The W681512WG also supports both mono and stereo audio channels.

The W681512WG provides a wide range of features to enable a user to customize the audio experience. An on-chip codec, Advanced Voice Cancellation (AVC), eliminates background noise while delivering clear voice quality. An active noise cancellation feature eliminates low and mid frequency noise. A built-in equalizer enables the user to tailor the audio performance depending on their individual preferences. Furthermore, the W681512WG supports 3D audio and surround sound for an even more enhanced listening experience.

The W681512WG also supports a Digital Input/Output Audio Interface (DI/OI) that allows connection to external interfaces, such as digital receivers, digital amplifiers, digital speakers, portable devices, and other digital audio devices. This feature enables the user to connect digital audio device to their computer, thereby allowing the user to listen to their favorite audio sources, such as CDs and music files, through a high-quality digital interface. This feature also enables the connection of HDMI (High-Definition Multimedia Interface) devices, allowing the user to enjoy high-quality, high-definition audio.

In conclusion, the W681512WG is a highly integrated stereo audio codec that is suitable for a wide range of applications. It is able to provide high-quality digital audio and supports a multitude of audio codecs. It also supports Digital Input/Output Audio Interface (DI/OI) connections and provides features such as Advanced Voice Cancellation (AVC) and Active Noise Cancellation (ANC). This makes the W681512WG an ideal choice for digital audio applications, such as digital multimedia players, digital speakers, and multimedia telephones.
