From e1315cf0b63b4c14a77046519e6b01f6f60d74b0 Mon Sep 17 00:00:00 2001 From: Eric Laurent Date: Tue, 17 May 2011 19:16:02 -0700 Subject: New effect library API Moved and renamed media/EffectApi.h to hardware/audio_effect.h Modified the effect library API to expose a library info structure containing an interface functions table. Also removed enums for audio channels, audio format and devices from effect API and use values from system/audio.h instead. Modified effects factory to support new library interface format and load libraries and efffects listed in audio_effects.conf file. The file audio_effects.conf is first loaded from /vendor/etc and then from /system/etc/audio_effects.conf if not found. Modified existing effect libraries to implement the new library interface.
