Video Review: 索尼创意软件 SpectraLayers Pro

索尼创意软件 recently announced a new product called SpectraLayers. 这到底是什么意思? A more descriptive name might "Photoshop for Audio." Or maybe, "The Fake Forensic Audio Manipulation You See on CSI 比你想象的更真实."

spectralayer是一种不同的音频工具. I thought it interesting that this is being distributed by SCS under a partnership with a company called Divide Frame. SpectraLayers has been used in sound design for several major motion pictures and popular video game soundtracks. It can now find a home in your arsenal of tools as well. spectralayer可用于Mac和PC.

现实世界的 CSI 音频取证?

我提到了电视节目 CSI 在这一页的顶部. It always bugs me when those shows take liberties with media content such as security camera footage and audio recordings. "Zoom in on the perp" and the bad guy pops up in full resolution after a 400% zoom. In our world, that just doesn't happen with your typical security camera.

录音也是同样的道理.“隔离电话里的男性声音!“你不能。 真的 除了在电视上，都是这样，对吧? 好吧, with the tools in SpectraLayers and some time spent on the details, you can achieve results that you might have thought impossible before.

什么是频率，光谱?

Essentially, SpectraLayers works on audio frequencies. 在主屏幕上, you won't see a typical waveform like you might in your NLE, 穴鸟, 或者其他音频编辑器. Those waveforms show volume or amplitude over time. In the SpectraLayers main timeline, you see frequencies over time. What we're going to attempt to do in the video review/tutorial below is remove the siren without adversely affecting the rest of the file. We'll be working with a basic WAV file that's already mixed down—nothing fancy. 从某种意义上说，我们会 un混合它，并尝试删除其中一个声音.

在接下来的视频中, I show how to isolate specific frequencies and their related harmonics, 以及如何, 通过相位反转, you can dial out very specific layers that were originally part of the mixed file.

现在, before you go trying to re-mix a Katy Perry tune, understand that it's not this simple and fool-proof for every audio track. Where SpectraLayers is more likely to be used is to provide very surgical, 精确控制音频清理. 例如,if you've got recorded dialog that contains an airplane flying overhead, you can get very precise with the frequencies of the airplane or other recorded noise. In other Noise Reduction tools you typically will take a small sample of pure noise from the file and the program will use phase inversion, 均衡, 以及其他减少噪音的技术. 使用SpectraLayers，您可以选择精确的, specific frequencies and harmonics to remove even if they exist only in combination with audio that you want to keep.

SpectraLayers is a fantastic fun tool to work with. I hope you have enjoyed this overview, and we will see you next time at 流媒体 Producer.
