+V18 - 5/6/02

+ +

All source code and documentation now under CVS. +
Ran most of the code through AStyle +to cleanup ragged indentation caused by using different editors. Used this +command: +
astyle --style=ansi -c -o --convert-tabs --indent-preprocessor +*.c

+ +

Added "pa_common/pa_convert.c" for Mac OS X. Start of new conversion +utilities. +
ASIO +
+
+New Pa_ASIO_Adaptor_Init function to init Callback adpatation variables,
+ +
+Cleanup of Pa_ASIO_Callback_Input
+ +
+Break apart device loading to debug random failure in Pa_ASIO_QueryDeviceInfo
+ +
+Deallocate all resources in PaHost_Term for cases where Pa_CloseStream +is not called properly
+ +
+New Pa_ASIO_loadDriver that calls CoInitialize on each thread on Windows. +Allows use by multiple threads.
+ +
+Correct error code management in PaHost_Term, removed various compiler +warning
+ +
+Add Mac includes for <Devices.h> and <Timer.h>
+ +
+Pa_ASIO_QueryDeviceInfo bug correction, memory allocation checking, better +error handling
+
+Mac OS X +
+
+Major cleanup and improvements.
+ +
+Fixed device queries for numChannels and sampleRates,
+ +
+Audio input works if using same CoreAudio device (some HW devices make +separate CoreAudio devices).
+ +
+Added paInt16, paInt8, format using new "pa_common/pa_convert.c" file.
+ +
+Return error if opened in mono mode cuz not supported.
+ +
+Check for getenv("PA_MIN_LATEWNCY_MSEC") to set latency externally.
+ +
+Use getrusage() instead of gettimeofday() for CPU Load calculation.
+
+Windows MME +
+
+Fixed bug that caused TIMEOUT in Pa_StopStream(). Added check for past_StopSoon() +in Pa_TimeSlice(). Thanks Julien Maillard.
+ +
+Detect Win XP versus NT, use lower latency.
+ +
+Fix DBUG typo;
+ +
+removed init of CurrentCount which was not compiling on Borland
+ +
+general cleanup, factored streamData alloc and cpu usage initialization
+ +
+stopped counting WAVE_MAPPER when there were no audio cards plugged in
+
+Windows DirectSound +
+
+Detect Win XP and Win 2K properly when determining latency.
+
+Unix OSS +
+
+Use high real-time priority if app is running with root priveledges. Lowers +latency.
+ +
+Added watch dog thread that prevents real-time thread from hogging CPU +and hanging the computer.
+ +
+Check error return from read() and write().
+ +
+Check CPU endianness instead of assuming Little Endian.
+
+

+ +

+V17 - 10/15/01

+ +

Unix OSS +
+
+Set num channels back to two after device query for ALSA. This fixed a +bug in V16 that sometimes caused a failure when querying for the sample +rates. Thanks Stweart Greenhill.
+
+

+ +

+
+Macintosh Sound Manager
+ +
+
+Use NewSndCallBackUPP() for CARBON compatibility.
+
+

+ +

+V16 - 9/27/01

+ +

Added Alpha implementations for ASIO, SGI, and BeOS! +
+
+CPULoad is now calculated based on the time spent to generate a known number +of frames. This is more accurate than a simple percentage of real-time. +Implemented in pa_unix_oss, pa_win_wmme and pa_win_ds.
+ +
+Fix dither and shift for recording PaUInt8 format data.
+ +
+Added "patest_maxsines.c" which tests Pa_GetCPULoad().
+

+ +

+
+Windows WMME
+ +
+
+sDevicePtrs now allocated using GlobalAlloc(). This prevents a +crash in Pa_Terminate() on Win2000. Thanks Mike Berry for finding this. +Thanks Mike Berry.
+ +
+Pass process instead of thread to SetPriorityClass(). This fixes +a bug that caused the priority to not be increased. Thanks to Alberto di +Bene for spotting this.
+
+ +
+Windows DirectSound
+ +
+
+Casts for compiling with __MWERKS__ CodeWarrior.
+
+ +
+UNIX OSS
+ +
+
+Derived from Linux OSS implementation.
+ +
+Numerous patches from Heiko Purnhagen, Stephen Brandon, etc.
+ +
+Improved query mechanism which often bailed out unnecessarily.
+ +
+Removed sNumDevices and potential related bugs,
+ +
+Use getenv("PA_MIN_LATENCY_MSEC") in code to set desired latency. +User can set by entering:
+ +
export PA_MIN_LATENCY_MSEC=40
+ +
+Macintosh Sound Manager
+ +
+
+Pass unused event to WaitNextEvent instead of NULL to prevent Mac OSX crash. +Thanks Dominic Mazzoni.
+ +
+Use requested number of input channels.
+ +

+

+ +

+V15 - 5/29/01

+ +

+
+
+New Linux OSS Beta
+
+ +
+Windows WMME
+ +
+
+ sDevicePtrs now allocated based on sizeof(pointer). Was allocating +too much space.
+ +
+ Check for excessive numbers of channels. Some drivers reported bogus +numbers.
+ +
+Apply Mike Berry's changes for CodeWarrior on PC including condition including +of memory.h, and explicit typecasting on memory allocation.
+
+ +
+Macintosh Sound Manager
+ +
+
+ScanInputDevices was setting sDefaultOutputDeviceID instead of sDefaultInputDeviceID.
+ +
+Device Scan was crashing for anything other than siBadSoundInDevice, but +some Macs may return other errors! Caused failure to init on some G4s under +OS9.
+ +
+Fix TIMEOUT in record mode.
+ +
+Change CARBON_COMPATIBLE to TARGET_API_MAC_CARBON
+
+

+ +

+V14 - 2/6/01

+ +

+
+
+Added implementation for Windows MultiMedia Extensions (WMME) by Ross and +Phil
+ +
+Changed Pa_StopStream() so that it waits for the buffers to drain.
+ +
+Added Pa_AbortStream() that stops immediately without waiting.
+ +
+Added new test: patest_stop.c to test above two mods.
+ +
+Fixed Pa_StreamTime() so that it returns current play position instead +of the write position. Added "patest_sync.c" to demo audio/video sync.
+ +
+Improved stability of Macintosh implementation. Added timeouts to prevent +hangs.
+ +
+Added Pa_GetSampleSize( PaSampleFormat format );
+ +
+Changes some "int"s to "long"s so that PA works properly on Macintosh which +often compiles using 16 bit ints.
+ +
+Added Implementation Guide
+
+

+ +

+V12 - 1/9/01

+ +

+
+
+Mac now scans for and queries all devices. But it does not yet support +selecting any other than the default device.
+ +
+Blocking I/O calls renamed to separate them from the PortAudio API.
+ +
+Cleaned up indentation problems with tabs versus spaces.
+ +
+Now attempts to correct bogus sample rate info returned from DirectSound +device queries.
+
