Leopard Reference Library: Audio
Core Audio's Hardware Abstraction Layer (HAL) ensures that audio realtime performance on Mac OS X is free from latency and multichannel access issues. The HAL publishes timing data so that developers know exactly where their audio is. Game developers benefit from Apple's improvements to OpenAL. Audio developers can fine-tune their applications for high performance using tools such as the Sampler code-profiling application, features such as multiprocessing, and APIs such as those for the vDSP library.
