* Increase allowed number of VHQ resamplers to 3Glenn Kasten2012-10-221-1/+1

* Integrate improved coefficient sinc resampler: VHQGlenn Kasten2012-10-041-16/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* audioflinger: use resample coefficients from audio-resampler library.SathishKumar Mani2012-09-261-3/+6
| | | | | | | | | | | -Add a separate quality VERY_HIGH_QUALITY in resampler -Use resample coefficients audio-resampler library for quality VERY_HIGH_QUALITY. -This improves the quality of resampled output.

* Whitespace and indentationGlenn Kasten2012-03-131-1/+1
| | | | | | | | | | | | | | Fix indentation to be multiple of 4. Make it easier to search: sp< not sp < to "switch (...)" instead of "switch(...)" (also "if" and "while") Remove redundant blank line at start or EOF. Remove whitespace at end of line. Remove extra blank lines where they don't add value. Use git diff -b or -w to verify.

|\ | | | | | | | | | | | | resampler" * commit '4430670f48f75661293371dab8db55865f5f56e0': audioflinger: Enable ARMv5TE optimized resampler
| * audioflinger: Enable ARMv5TE optimized resamplerJim Huang2011-04-071-2/+6
| | | | | | | | | | | | | | | | | | | | Previously, the optimized asm option is only enabled when __ARM_ARCH_5E__ is defined, which is assigned in armv5te.mk rather than armv7-a series targets. This patch checks the ARM CPU feature about half-word multiply instructions to enable ARMv5TE resampler optimization routines properly. Change-Id: I4c5a5d8c932416f23bedb0b389db958349f21ea4
* | 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
