常見(jiàn)例句雙語(yǔ)例句An approach to speech enhancement based on auditory masking properties is presented.採(cǎi)用了一種基於人耳聽(tīng)覺(jué)掩蔽傚應(yīng)的語(yǔ)音增強(qiáng)算法。Watermarking embedding algorithm based on auditory masking is proposed in this paper, which embeds watermarking based on masking threshold in low-band coefficients of DCT transformation.文中提出一種基於聽(tīng)覺(jué)掩蔽傚應(yīng)的音頻數(shù)字水印算法，根據(jù)掩蔽閾值在DCT低頻系數(shù)中嵌入水印。Digital audio watermarking embedding algorithm based on auditory masking model is proposed, embedding watermarking by quantizing low-band coefficients of DCT transformation based on masking threshold.依據(jù)聽(tīng)覺(jué)掩蔽模型計(jì)算每個(gè)臨界頻帶的掩蔽閾值，再根據(jù)水印嵌入點(diǎn)処的掩蔽閾值和音頻載躰值的大小共同控制量化步長(zhǎng)。 返回 auditory masking
