* OpenSL ES: volume support for QAudioInput.Yoann Lopes2014-12-032-5/+17
| | | | | | | | | The OpenSL volume interface is not available for audio inputs on Android so we apply the volume ourselves on the PCM data. Task-number: QTBUG-42159 Change-Id: If43d8aa576bc70a925681f0db1ca8b40e71f7b29 Reviewed-by: Christian Stromme <christian.stromme@theqtcompany.com>
* OpenSL ES: improve buffer logicChristian Strømme2014-11-042-8/+27
| | | | | | | | | | | | | Don't use relaxed load and stores, we need to be stricter to avoid problems with high frequency re-fills of the buffer. If we don't enforce ordering we might end-up spending more time trying to acquire an open slot in the buffer. Updating processes bytes is also moved off the "OpenSL" thread. Added some comments for improved readability. Change-Id: Ie27965fc6bf4b8394081ae6419f4933522ada98e Reviewed-by: Yoann Lopes <yoann.lopes@theqtcompany.com>
* OpenSL ES: Don't store or return the adjusted volume level.Christian Strømme2014-11-042-4/+2
| | | | | | | | | | According to our own docs we should always return 1.0 (MAX) volume level if the device doesn't support setting the volume, which is the case for OpenSL ES on Android.

* | OpenSL ES: Be less rigid about tearing down the output device.Christian Strømme2014-09-122-26/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We where very strict about tearing down the audio device. While this is a good strategy to avoid unnecessary resource usage, it also causes excessive re-allocations, e.g., when transiting from start to stop and back again. This can increase latency, especially in case where a short clip is re-played at a high frequency. This change also decrease the chance of the player ending up in some unknown state where it drops audio clips without any warning.

* OpenSL: Fix volume scaleChristian Strømme2013-12-021-1/+3
| | | | | | | | | | | | The old code was assuming that the interface was expecting power values, while it actually uses amplitude values. In addition the difference between the min/max values where used, resulting in quite high gain values.
