b4a22b91ff Fix ring buffer handling in pa_mac_core.c that caused many spurious paInputOverflow flags. 
Fixed size bug when input underflow detected. Code was confused between bytes and elements.

f69a02a99a Alsa: re-write SetApproximateSampleRate() to allow small deviations from a nominal requested rate, so inexactly clocked cards do not fail (use 1% tolerance). 2012-05-18 16:04:30 +00:00

1c9b4fe4b9 WDM-KS: 
- Fixed so default sample rate prioritizes frequencies earlier in search order
- Changed WIN32 to _WIN32 (as it is always defined, both in x86 & x64 builds)

32e0080310 ASIO: 
- Certain drivers write over the available memory of PaAsioDriverInfo, now a padding area makes sure
  the stack doesn't get corrupted.
WDM-KS:

6803965617 General: 
- Change of CMake options to utilize built in header configuration support (PA_USE_*)
- Added CMakeLists.txt for examples
- Added paex_ocean_shore.c as an example how to use PA ring buffer for lock-free communication with the audio callback
WDM-KS:
- Added better default sample rate support
- Made sure that all pins now have a name, even if only "Input" or "Output"
- IsUSBDevice fixed acc. to Alex Lessard's suggestion
- IsNameUSBAudioDevice fixed similarly

d998066452 alsa: 
- support for sub-devices;
- fixed 24-bit format support for some devices which on little-endian machine operate only in big-endian format, example of such device is Audio4DJ which supports only SND_PCM_FORMAT_S24_3BE (for this patch implemented support only for 24-bit audio samples although other formats may be added in case of necessity and if such devices exist);
! special thanks to Owen Williams from Mixxx project who tested these changes/fixes on real Audio4DJ device.

9bc432b603 wasapi: 
- fixed device name incorrect in case it contains non-Latin characters (thanks to Robert Bielik for proposed solution), now it is converted to UTF-8 encoded string
- fixed damaged audio (pops & clicks) for Input exclusive event-driven mode if specified latency was below 23 ms

0a05ae27fe fixed bug in coreaudio host api: suggested latency of zero with fixed user buffer size resulted in min supported buffer size instead of requested user buffer size 2012-01-11 13:22:50 +00:00

c1390f8c18 fixed regression in r1718 (PA/coreaudio) where PA callback timestamps would be offset by massive latency (frames interpreted as seconds) if the initial query for actual device sample rate failed. This checkin reinstates the use of nominal sample rate as default for latency calculations when actual sample rate query fails. 2011-12-27 08:58:59 +00:00

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
