摘要	Quantization Watermarking or Quantization Index Modulation is usually used for uniform scalar quantizarion. In this article, the Quantizaion Watermarking extendedly refers to all the watermarking schemes that achieve watermark embedding during quantization process, ignoring the concrete method: scalar or vector quantization. After a brief review of audio watermarking, this paper mainly introduces the watermarking techniques, whose aim is to embed watermark in the quantized MDCT coefficients of AAC or the index value of TwinVQ. Some experimental results show that it works well, for the distortion coming from quantization watermarking is limited within the HAS thresholds, and the embedded watermark is difficult to be removed without significantly audio quality degrading and the key only known by the owner.
