    <p>I would like to do this very simple thing: playing PCM audio data from memory.</p> <p>The audio samples will come from sound-synthesis algorithms, pre-loaded sample files or whatever. My question is really about how to play the buffers, not how to fill them with data.</p> <p>So I'm looking for the best way to re-implement my old, deprecated <em>AudioWrapper</em> (which was based on AudioUnits V1), but I could not find in the <a href="https://developer.apple.com/library/ios/#documentation/MusicAudio/Conceptual/CoreAudioOverview/CoreAudioEssentials/CoreAudioEssentials.html" rel="nofollow noreferrer">Apple Documentation</a> an API that would fulfill the following:</p> <ul> <li>Compatible with 10.5 through 10.7.</li> <li>Available in ios.</li> <li>Does not rely on a third-party library.</li> <li>Be future proof (for example: not based on Carbon, 64 bits...).</li> </ul> <p>I'm considering using OpenAL, but is it really the best option ? I've seen <a href="https://stackoverflow.com/questions/4014614/ios-audio-units-vs-openal-vs-core-audio">negative opinions</a> about it, it might be too complex and overkill, and might add performance overhead ?</p> <p>At worse, I could have two different implementations of that <em>AudioWrapper</em>, but if possible, I'd really like to avoid having one version for each system (ios, 10.5, 10.6, 10.7...). Also, it will be in C++.</p> <p><strong>EDIT:</strong> I need a good latency, the system must respond to user interactions in under 20 ms (the buffers must be between 128 and 512 samples at 44KHz)</p>

    1. COOpenAL adds a bit more overhead, and setup takes longer than using the native audio APIs, so on iOS I would suggest using either AudioQueues or AVFoundation.

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.
