本文介绍采用现代数字技术解决音频延时的问题。在这样的系统中,把音频信号转换为数字序列,贮存在移位寄存器里,得到所需的延迟时间后,再转换为输出音频信号。本文还讨论了决定有效信噪比、带宽和存储要求的理论基础。 This article describes the use of modern digital technology to solve the problem of audio delay. In such a system, the audio signal is converted to a digital sequence, stored in a shift register, and the desired delay time is converted into an output audio signal. This article also discusses the rationale for determining the effective signal-to-noise ratio, bandwidth, and storage requirements.
