* opus_pvq: remove unneeded assertRostislav Pehlivanov2017-02-241-1/+0
| | | | | | | | | | Since the PVQ search has been well fuzzed and is guaranteed to never break SUM(abs(y[])) == K, the assert is no longer needed. Also the assert only prevented coding the wrong vector index but didn't prevent crashes during searching for it, which made the assert rather informational than practical. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
* opus_pvq: improve PVQ search for low KsRostislav Pehlivanov2017-02-241-2/+5
| | | | | | | | | Since the probelm mentioned only happened when the phase was negative (e.g. the sum had to be decreased), only discarding dimensions with a zero pulse in that case restored the search's previously low distortion at low Ks when the phase is never negative.
