* LoudnessEnhancer compatible with stereo imagingJean-Michel Trivi2013-09-263-1/+39
| | | | | | | | | Use a single compressor for both channels. Envelope of signal is determined by looking at both channels. Bug 8413913 Change-Id: Ia9b6f34923d2977c60a3352500b858dfa1fab33c
* LoudnessEnhancer audio effect implementationJean-Michel Trivi2013-09-179-0/+760
Implementation based on DRC effect, controlled by a target gain. The target gain is used to amplify the signal at the input of the DRC, and to compute the knee of the DRC. Bug 8413913 Change-Id: I386d64793a9fa3f7218e053d6f0a99f6836c02bd
