4b7c5a1241 Experiment with moving example code into its own folder.
Note that this revision needs to have autoreconf run.
I tried to do that on Mac but it failed. So I will try on Linux.

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.

91d6a84b55 added stream callback documentation describing real-time constraints including not calling non-real-time code, and that it should be safe to consume 70% or more of available CPU time in the callback. resolves #96 2011-08-25 17:44:01 +00:00

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

f22cec3d45 moved memory barriers as per this thread: http://music.columbia.edu/pipermail/portaudio/2011-August/012803.html . use volatile because MSVC Read/WriteBarrier() intrinsics are just compiler barriers, but MSVC will insert memory barriers if you use volatile. see: http://msdn.microsoft.com/en-us/library/ms686355(VS.85).aspx 2011-08-18 11:19:36 +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.
