iPhone：CPU电源做DSP /傅立叶变换/频域？ [英] iPhone: CPU power to do DSP/Fourier transform/frequency domain?

问题描述

欲分析在持续的基础上的MIC的音频（不只是一个剪断或prerecorded样品），和显示频率图表并过滤出音频的某些方面。是iPhone足够强大是什么？我怀疑，答案是是的，鉴于谷歌和iPhone语音识别，Shazaam等音乐识别应用程序，和吉他调谐器应用程式在那里。但是，我不知道我会要处理什么限制。

I want to analyze MIC audio on an ongoing basis (not just a snipper or prerecorded sample), and display frequency graph and filter out certain aspects of the audio. Is the iPhone powerful enough for that? I suspect the answer is a yes, given the Google and iPhone voice recognition, Shazaam and other music recognition apps, and guitar tuner apps out there. However, I don't know what limitations I'll have to deal with.

任何人玩弄这个领域？
