| @jd:body |
| |
| <p>The NDK package includes an Android-specific implementation of the |
| <a class="external-link" href="https://www.khronos.org/opensles/">OpenSL ES™</a> API |
| specification from the <a class="external-link" href="https://www.khronos.org">Khronos Group</a>. |
| This library allows you to use C or C++ to implement high-performance, low-latency audio, whether |
| you are writing a synthesizer, digital audio workstation, karaoke, game, |
| or other real-time app.</p> |
| |
| <p>This section begins by providing some |
| <a href="{@docRoot}ndk/guides/audio/basics.html">basic information</a> about the API, including |
| typical use cases and how to incorporate it into your app. It then explains what you need to know |
| about the <a href="{@docRoot}ndk/guides/audio/opensl-for-android.html">Android-specific |
| implementation</a> of OpenSL ES, focusing on the differences between this implementation and the |
| reference specification. Next, you'll learn how to minimze |
| <a href="{@docRoot}ndk/guides/audio/input-latency.html">input latency</a> |
| when using built-in or external microphones |
| and some actions that you can take to minimize |
| <a href="{@docRoot}ndk/guides/audio/output-latency.html">output latency</a>. |
| It describes the reasons that you should use |
| <a href="{@docRoot}ndk/guides/audio/floating-point.html">floating-point</a> |
| numbers to represent your audio data, and it provides information that will help you choose the |
| optimal <a href="{@docRoot}ndk/guides/audio/sample-rates.html">sample rate</a>. This section |
| concludes with some supplemental <a href="{@docRoot}ndk/guides/audio/opensl-prog-notes.html"> |
| programming notes</a> to ensure proper implementation of OpenSL ES. |
