采样率表示音频信号每秒的数字快照数。该速率决定了音频文件的频率范围。采样率越高,数字波形的形状越接近原始模拟波形。低采样率会限制可录制的频率范围,这可导致录音表现原始声音的效果不佳。 根据 奈奎斯特采样定理,为了重现给定频率,采样率必须至少是该频率的两倍。例如,CD 的采样率为每秒 44,100 个采样,因此可重...
本章主要讲述如何通过AndroidOpenSL 实现录制 PCM 音频数据。开发流程回顾可以看下笔者前面发布过的文章。 开发准备 1.在Android studo下面建立工程,在使用OpenSL ES的API之前,首先需要引入CMakeLists.txt里面添加依赖库和链接库,代码如下: 代码语言:txt AI代码解释 find_library( # Sets the name of the path varia...

Stanford researchers have been using superlattice materials and flexible substrate to lower PCM (phase-change memory) switch power.
Tascam Hi Res Editor在高频部分有噪声,原因未知,不过用于频谱分析已经足够(不会有人听DSD还要先转PCM吧) 鉴于笔者水平有限,文中用词、表述、内容可能存在错误,仅作记录,欢迎交流讨论 参考: https://docs.google.com/spreadsheets/d/1rHcXP7PExksxZfkif3Rv2CT1Y_ESpNSv2b0nkKlBySk/edit?pli=1#gid=1396547041...
