    <p>I am adding a voice memo capability using AVAudioRecorder and I need to know the best settings for the recorder for recording voice. </p> <p>Unfortunately, I know nothing about audio to the extent I am not even sure what terms to google for. </p> <p>Currently, I am using the following which I copied from somewhere for testing purposes:</p> <pre><code>recorderSettingsDict=[[NSDictionary alloc] initWithObjectsAndKeys:[NSNumber numberWithInt:kAudioFormatAppleIMA4],AVFormatIDKey, [NSNumber numberWithInt:44100.0],AVSampleRateKey, [NSNumber numberWithInt: 2],AVNumberOfChannelsKey, [NSNumber numberWithInt:16],AVLinearPCMBitDepthKey, [NSNumber numberWithBool:NO],AVLinearPCMIsBigEndianKey, [NSNumber numberWithBool:NO],AVLinearPCMIsFloatKey, nil]; </code></pre> <p>or:</p> <pre><code>defaultSettings = { AVFormatIDKey = 1768775988; AVLinearPCMBitDepthKey = 16; AVLinearPCMIsBigEndianKey = 0; AVLinearPCMIsFloatKey = 0; AVNumberOfChannelsKey = 2; AVSampleRateKey = 44100; }; </code></pre> <p>This works but I don't know if it's optimal for voice in terms of quality, speed, file size etc. </p> <p>The <a href="http://developer.apple.com/iphone/library/documentation/AVFoundation/Reference/AVAudioRecorder_ClassReference/Reference/Reference.html#//apple_ref/doc/uid/TP40008238-CH1-SW9" rel="noreferrer">AVAudioRecorder Class Reference list many settings constants</a> but I have no clue which ones to use for voice.</p> <p>Baring that, if someone knows of a good "AudioFormats for Dummy's" resource I will take that as well. (Note:I've been through the Apple Docs and they assume a knowledge base in digital audio that I do not posses.)</p>

    1. COMan, I'm thinking it was a tactical error to post this on the day the iPad was announced.

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.
