* Add floating point volume handling to AudioMixerAndy Hung2014-07-081-4/+8
| | | | | | | | | | | | | | | Use floating point volume in AudioMixer mixing when floating point input is used with the new mixer engine. AudioResampler is updated to take floating point volume to match. Both legacy integer and floating point mixer engines work. For now, integer volume is used when the new mixer engine runs in integer input mode, for backward compatibility with the legacy mixer. The new mixer engine will generally run in floating point input mode. When the legacy path is removed, the integer volumes will be removed. Change-Id: I79e80c292ae7c8b8bdd0aa371a1b2c3a1b618290

| * reenable the cubic resamplerMathias Agopian2012-10-261-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | cubic resampler was disabled because it hadn't been qualified, however after I did some tests, it does improve significantly the sound quality over the order-1 resampler, even if it is still quite bad. also HIGH_QUALITY resampler was partially disabled, it's now fully enabled. It's a big improvement over the cubic resampler in terms of aliasing noise (it's not as good in the pass-band). Change-Id: I70e3658c255896588642697be9eb594ff4ec0f8b

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Very high quality is enabled only for 44.1 -> 48 or 48 -> 44.1, and uses low quality for all other use cases. Track estimated CPU load and throttles the quality based on load; as currently configured it should allow up to 2 instances of very high quality. Medium quality and high quality are currently disabled unless explicitly requested. Details: Only load .so the first time it is needed. Cleanup code style: formatting, indentation, whitespace. Restore medium quality resampler, but it is not used (see next line). Fix memory leak for sinc resampler. Check sample rate in resampler constructor. Add logs for debugging. Rename DEFAULT to DEFAULT_QUALITY for consistency with other quality levels. Renumber VERY_HIGH_QUALITY from 255 to 4. Use enum src_quality consistently. Improve parsing of property af.resampler.quality. Fix reentrancy bug - allow an instance of high quality and an instance of very high quality to both be active concurrently.

* | Enable new dynamic audio resampler as defaultAndy Hung2014-01-301-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | The default may still be overridden by af.resampler.quality in the local or build properties file. For the build properties check the relevant device.mk files. In the absence of being overridden, the 44.1 to 48kHz and 48 to 44.1kHz conversion will use the DYN_MED_QUALITY resamplers and other conversion will use the DYN_LOW_QUALITY resamplers.

* | Fix issue 3479042.Eric Laurent2011-02-281-0/+6
|/ | | | | | | | | | | | | | | | The problem is that when an AudioRecord using the resampler is restarted, the resampler state is not reset (as there is no reset function in the resampler). The consequence is that the first time the record thread loop runs, it calls the resampler which consumes the remaining data in the input buffer and when this buffer is released the input index is incremented over the limit. The fix consists in implementing a reset function in the resampler. A similar problem was also present for playback but unoticed because the track buffer is always drained by the mixer when a track stops. The only problem for playback was that the initial phase fraction was wrong when restarting a track after stop (it was correct after a pause). Change-Id: Ifc2585d685f4402d29f4afc63f6efd1d69265de3
