9cdd56f5b4 Implement the Float32 to UInt8 converters. 
The loopback test now passes cleanly for the first time on my PreSonus FireStudio.
Added tests for clip and dither flag combinations to loopback.

4939e41248 Fixed directsound PaDeviceInfo default latency and PaStreamInfo latency fields. Fixed host buffer size calculations based on suggestedLatency parameters. Switched to using 48kHz as default sample rate when other info isn't available. Fixed edge case in TimeSlice() where a full duplex stream could read data even though either input or output reported zero bytes available. Renamed some variables for clarity. Fixes ticket #160 (PaStreamInfo latency). Addresses #122 (although we're still using old default latency values from V18 codebase). Addresses #99 (correct interpretation of suggestedLatency down to zero). 2011-08-25 15:59:32 +00:00

16f40db4c8 wmme limit host buffer size to 32k. try to make host buffer size a factor of over-limit user buffer size. closes #189 2011-08-25 07:15:31 +00:00

fa8a45c845 Fix removal of device property change listeners. 
This may fix some occasional memory corruption isses we were seeing in the loopback test.
I think the listeners may have gotten called after the stream was freed.

28397f5c4a Replaced MM timer with a high priority thread for audio compute, based on a patch by Dmitry Kostjuchenko. Reason: there is one global MM timer thread per process and doing audio compute in it was interfering with timer accuracy and also with running multiple DSound streams. The old MM timer based implementation is still available if you define PA_WIN_DS_USE_WMME_TIMER -- this may be removed in future. 2011-05-11 10:00:52 +00:00

9c4c92fef6 alsa: 
- implemented dynamic ALSA loading, you shall define PA_ALSA_DYNAMIC when compiling PortAudio library, by default PortAudio will use compile time linkage;
- added PA_ALSA_PATHNAME define to redefine ALSA library path and filename to some other name and location, has effect only together with PA_ALSA_DYNAMIC;
- added extension function (PaAlsa_SetLibraryPathName) which allows to set ALSA library path and filename during application run-time overwriting default set by PA_ALSA_PATHNAME during compilation;
- added API compatibility with Android OS (although ALSA may not be available on your device and usually requires 'root' access rights to open an audio device), some missing ALSA functions are replaced with stubs (needs more input from interested parties), to compile on Android you need to add ALSA headers (get it from Android GIT source-code tree) to compiler's searchable path.

4318a7556b alsa: 
- fixed callback thread to exit normally if error condition was satisfied during stream processing (OnExit wasn't called), it was possible cause of crash if error happened inside the thread
- modified processing thread to timeout during poll() within around 2 seconds instead of 64 milliseconds, this will help to fix problems on systems with low processing power and possible CPU overloading, like portable ARM devices
- timeout of poll() will not cause stream to stop but will cause Alsa stream restart, poll timeout will now set 'xrun' event to 1
