WebbWhen dealing with high sample rates, you’re going to end up with large files. To get a rough idea of how big a file is going to be, you can use these calculations: Sample rate (in hertz not kilohertz) x Bit rate x Number of channels x Number of seconds = total bits; Total bits / 8 = bytes; Bytes / 1,000,000 = megabytes or MBs; For example: Webb6 juli 2024 · 易采站长站为你提供关于视频已逐渐超过文字和图片，可以说成为了现在使用最广的媒体形式，同时也占据了用户更多的浏览时间，这就使得视频理解变得尤为重要。各大互联网公司与顶尖高校纷纷绞尽脑汁，竞相研究SOTA的视频理解模型与算法。在谷歌，脸书，Open-MM Lab等分别祭出各家杀器之后，脸 ...

WebbSo a sample rate that is 40 kHz should technically do the trick, right? This is true, but you need a pretty powerful—and at one time, expensive—low-pass filter to prevent audible aliasing. The sample rate of 44.1 kHz technically allows for audio at frequencies up to 22.05 kHz to be recorded. http://easck.com/news/2024/0706/672954.shtml
