About Audio and Video

Whether multimedia features are central or incidental to your application, iPhone, iPod touch, and iPad users expect high quality. When presenting video content, take advantage of the device’s high-resolution screen and high frame rates. When designing the audio portion of your application, keep in mind that compelling sound adds immeasurably to a user’s overall experience.

You can take advantage of the iOS multimedia frameworks for adding features like:

• High-quality audio recording, playback, and streaming

• Immersive game sounds

• Live voice chat

• Playback of content from a user’s iPod library

• Video playback and recording on supported devices

In iOS 4.0 and later, the AV Foundation framework gives you fine-grained control over inspecting, editing, and presenting audio-visual assets.
