心理声学模型 meaning in Chinese
psychoacoustic model
Examples
- In this dissertation , psychoacoustic models filter banks quantization and bit allocation predicate coding and temporary noise shaping is analyzed
本文首先对心理声学模型、滤波器组、量化和比特分配、预测编码、时域噪声成型等技术进行研究。 - A parametric psychoacoustic model based on critical band rate , level - dependent spreading function , non - linear superposition and forward masking was proposed
摘要提出了基于临界频带率、依赖于强度的扩展函数、非线性迭加和前向掩蔽效应的参数心理声学模型。 - The experiments verify that with these new technologies , the amount of sinusoids can be greatly reduced and the tracking efficiency can be greatly improved
实验证明，将这两种方法与参数心理声学模型相结合，可以有效地减少所需的正弦波数量，大大提高正弦波跟踪的效率。 - Furthermore , on the analysis of the psychoacoustic models , some simplification can be made in the psychoacoustic models . the purpose of this simplification is to reduce the bit rate of audio stream
此外，基于对心理声学模型的分析，对心理声学模型作若干近似，简化的目的是为了用较少的比特编码音频数据。 - The newly proposed method makes good use of the psychoacoustic model . and the perceptual information contained in the synthesized signal is increased in a furthest way during the modeling procedure
感知梯度正弦建模比较好地利用了心理声学模型，在建模过程中最大限度地增加合成信号的感知信息，提高了建模效率。
