    <p>I have searched for this online, but am still a bit confused (as I'm sure others will be if they think of something like this). I'd like to preface by saying that this is <em>not</em> for homework and/or profit.</p> <p>I wanted to create an app that could listen to your microwave as you prepare popcorn. It would work by sounding an alarm when there's a certain time interval between pops (say 5-6 seconds). Again, this is simply a project to keep me occupied - not for a class.</p> <p>Either way, I'm having trouble trying to figure out how to analyze the audio intake in real-time. That is, I need a way to log the time when a "pop" occurs. So that you guys don't think I didn't do any research into the matter, I've checked out <a href="https://stackoverflow.com/questions/2257075/real-time-audio-processing-in-android">this</a> SO question and have extensively searched the <a href="http://developer.android.com/reference/android/media/AudioRecord.html#read%28short%5B%5D,%20int,%20int%29" rel="nofollow noreferrer">AudioRecord</a> function list.</p> <p>I'm thinking that I will probably have to do something with one of the versions of <a href="http://developer.android.com/reference/android/media/AudioRecord.html#read%28short%5B%5D,%20int,%20int%29" rel="nofollow noreferrer">read()</a> and then compare the recorded audio every 2 seconds or so to the recorded audio of a "pop" (i.e. if 70% or more of the byte[] audioData array is the same as that of a popping sound, then log the time). Can anyone with Android audio input experience let me know if I'm at least on the right track? This is not a question of me wanting you to code anything for me, but a question as to whether I'm on the correct track, and, if not, which direction I should head instead.</p>

    2. CO^ I've already referenced that question in my question. My question is more of whether I'm heading in the right direction given my specific needs for real-time audio analysis.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
