| Features : |
|
|
ACC is a mono / stereo audio codec. |
|
ACC offers low end-to-end delay (less than 50 ms, for sampling frequencies between 32 kHz and 48 kHz) by minimizing the size of the transform, and look-ahead and bit-stream buffers. |
|
ACC uses intra-frame coding strategies only, insuring high intrinsic error robustness, facilitating error concealment, providing high time resolution in bit stream access, and facilitating special effects such as fast-rewind and fast-forward play modes. |
|
ACC allows instantaneous bitrate switching "on-the-fly" easing the operation in fast bandwidth changing environments. |
|
ACC implements efficient bandwidth extension using ATC Labs proprietary technology : ABET |
