Can I get the frequency of a raw sound in real time in Android?
<p>I would like to build an app that can tell the frequency of a musical note played through a androids mic as quickly as possible.</p>

<p>Disclaimer: I am not building a another tuner app, I promise ;)</p>

<p>I am aware of the difficulty of getting the frequency, I will probably use FFT.</p>

<p>But how quickly can i realisticly get whether the sound being played is an expected note?</p>

<p>i.e. is the recorded half a second of a sound an A, or B etc.</p>

<p>Thanks in advance :)</p>

<p>Ben</p>
