UnverifiedSilence detection is typically based on the RMS (Root Mean Square) energy value of an audio signal; when the RMS of an audio segment is below a preset threshold and its duration exceeds the minimum silence length, that segment is marked as a silence candidate.74% similarUnverifiedMel频谱图是模拟人耳听觉感知非线性特性的时频表示，通过STFT后经Mel刻度上均匀分布的三角滤波器组（通常80或128个）并取对数得到，相比原始波形将数据维度压缩约一到两个数量级67% similarUnverified信噪比概念原本来自电信工程，用于衡量有效信号相对于背景噪声的强度66% similarUnverified人类听觉系统对音高的感知包含两个正交分量：音调高度（tone height）和音调色彩（tone chroma），这一特性被称为「音高螺旋」模型66% similar
