AAC ENCODER

Advanced Audio Coding Encoder C55x

The Adaptive Digital Technologies MPEG4-AAC (LC/LTP) Encoder compresses audio to low bit rates while maintaining near CD quality.

AAC DECODER

Advanced Audio Decoder C55x

The Adaptive Digital Technologies MPEG4-AAC (LC/LTP) Decoder decodes MPEG4 AAC bit streams. The AAC decoder supports MPEG4 audio decoding for ADIF (audio data interchange format) and ADTS (audio data transport stream) encoded data.

AAC LC ENCODE / DECODE

Advanced Audio Encode/Decode LC C64x

The AAC-LC (Advanced Audio Coding) encoder/decoder is an implementation of the MPEG-2 (ISO/IEC 13818-3) and MPEG-4 (ISO/IEC 14496-3) standard. MPEG-2/4 AAC is a standard for compressing/decompressing audio sampled at 8-96 Khz to bit-rates of 16-576 kbit/s. AAC provides higher quality than MP3 at the same bit rate. It supports the coding of multi-channel audio, with up to 48 main channels and 16 low-frequency channels. AAC offers multiple profiles/object types to meet the requirements of a wide range of applications.

AAC LD ENCODE / DECODE

Advanced Audio Low Delay (LD) Encoder/Decoder C64x

The AAC-LD (Advanced Audio Coding) MPEG-4 Low Delay Audio Coder is designed to combine the advantages of perceptual audio coding with the low delay necessary for two-way communication. It has achieved wide acceptance in high end video conference terminals and is used in professional broadcasting applications.

WMA DECODER

Windows Media Audio Decoder C55x - C54x

The Adaptive Digital Technologies WMA Decoder is Class 4 implementation of WMA decoder, fully support all versions of WMA namely V2, V7, V8, V9, V9beta, V9NC and VBR(Variable Bit Rate) . The WMA decoder converts audio data in compressed format to uncompressed format(16bit raw PCM). It supports sampling frequencies from 8 kHz to 48 kHz and all bit-rates specified by the standard.

MPEG3 DECODER

MPEG1 Layer lll C55x

The Adaptive Digital Technologies MP3 Decoder is fully compliant with ISO/IEC 11172-3 (MPEG1 layer 3), ISO/IEC 13818-3.2 (MPEG2 audio) and MPEG2.5 standards as specified by ISO/IEC-11172-4 standard. The MP3 decoder converts audio data in compressed format to uncompressed format. It supports sampling frequencies from 8 kHz to 48 kHz and all bit-rates specified by the standard.

ADAPTIVE FEEDBACK CONTROL

AFC feedback control C55x - C54x

Adaptive Digital's Adaptive Feedback Control algorithm analyzes an input signal, determines whether or not there is a resonance, and eliminates the resonance while minimizing the effect on the desired signal.
