Bonk check the attack against a collection of stored templates to try

+Notes on status of CoreAudio Implementation of PortAudio
+
+Document Last Updated December 9, 2005
+
+There are currently two implementations of PortAudio for Mac Core Audio.
+
+The original is in pa_mac_core_old.c, and the newer, default implementation
+is in pa_mac_core.c.
+Only pa_mac_core.c is currently developed and supported as it uses apple's
+current core audio technology. To select use the old implementation, replace
+pa_mac_core.c with pa_mac_core_old.c (eg. "cp pa_mac_core_auhal.c
+pa_mac_core.c"), then run configure and make as usual.

+
+-------------------------------------------
+
+Notes on Newer/Default AUHAL implementation:
+
+by Bjorn Roche
+
+Last Updated December 9, 2005
+
+Principle of Operation:
+
+This implementation uses AUHAL for audio I/O. To some extent, it also
+operates at the "HAL" Layer, though this behavior can be limited by
+platform specific flags (see pa_mac_core.h for details). The default
+settings should be reasonable: they don't change the SR of the device and
+don't cause interruptions if other devices are using the device.
+
+Major Software Elements Used: Apple's HAL AUs provide output SR
+conversion transparently, however, only on output, so this
+implementation uses AudioConverters to convert the sample rate on input.
+A PortAudio ring buffer is used to buffer input when sample rate
+conversion is required or when separate audio units are used for duplex
+IO. Finally, a PortAudio buffer processor is used to convert formats and
+provide additional buffers if needed. Internally, interleaved floating
+point data streams are used exclusively - the audio unit converts from
+the audio hardware's native format to interleaved float PCM and
+PortAudio's Buffer processor is used for conversion to user formats.
+
+Simplex Input: Simplex input uses a single callback. If sample rate
+conversion is required, a ring buffer and AudioConverter are used as
+well.
+
+Simplex output: Simplex output uses a single callback. No ring buffer or
+audio converter is used because AUHAL does its own output SR conversion.
+
+Duplex, one device (no SR conversion): When one device is used, a single
+callback is used. This achieves very low latency.
+
+Duplex, separate devices or SR conversion: When SR conversion is
+required, data must be buffered before it is converted and data is not
+always available at the same times on input and output, so SR conversion
+requires the same treatment as separate devices. The input callback
+reads data and puts it in the ring buffer. The output callback reads the
+data off the ring buffer, into an audio converter and finally to the
+buffer processor.
+
+Platform Specific Options:
+
+By using the flags in pa_mac_core.h, the user may specify several options.
+For example, the user can specify the sample-rate conversion quality, and
+the extent to which PA will attempt to "play nice" and to what extent it
+will interrupt other apps to improve performance. For example, if 44100 Hz
+sample rate is requested but the device is set at 48000 Hz, PA can either
+change the device for optimal playback ("Pro" mode), which may interrupt
+other programs playing back audio, or simple use a sample-rate coversion,
+which allows for friendlier sharing of the device ("Play Nice" mode).
+
+
+Known issues:
+
+- Latency: Latency settings are ignored in most cases. Exceptions are when
+doing I/O between different devices and as a hint for selecting a realtively
+low or relatively high latency in conjunction with
+paHostFramesPerBufferUnspecified. Latency settings are always automatically
+bound to "safe" values, however, so setting extreme values here should not be
+an issue.
+
+- Buffer Size: paHostFramesPerBufferUnspecified and specific host buffer sizes
+are supported. paHostFramesPerBufferUnspecified works best in "pro" mode,
+where the buffer size and sample rate of the audio device is most likely
+to match the expected values.
+
+- Timing info. It reports on stream time, but I'm probably doing something
+wrong since patest_sine_time often reports negative latency numbers.
+
+- xrun detection: The only xrun detection performed is when reading
+and writing the ring buffer. There is probably more that can be done.
+
+- abort/stop issues: stopping a stream is always a complete operation,
+but latency should be low enough to make the lack of a separate abort
+unnecessary. Apple clarifies its AudioOutputUnitStop() call here:
+http://lists.apple.com/archives/coreaudio-api/2005/Dec/msg00055.html
+
+- blocking interface: Not implemented.
+
+- multichannel: It has been tested successfully on multichannel hardware
+from MOTU: traveler and 896HD.
+
+- sample rate conversion quality: By default, SR conversion is the maximum
+available. This can be tweaked using flags pa_mac_core.h. Note that the AU
+render quyality property is used to set the sample rat conversion quality
+as "documented" here:
+http://lists.apple.com/archives/coreaudio-api/2004/Jan/msg00141.html
+
+- x86: I haven't tested it on an x86 Mac myself, but users have reported
+being able to comiple and run it.

Status history
--------------
+10th November 2005:
+Made following changes:
+ * OpenStream: Try all PaSampleFormats internally if the the chosen
+ format is not supported natively. This fixed several problems
+ with soundcards that soundcards that did not take kindly to
+ using 24-bit 3-byte formats.
+ * OpenStream: Make the minimum framesPerHostIBuffer (and framesPerHostOBuffer)
+ the default frameSize for the playback/recording pin.
+ * ProcessingThread: Added a switch to only call PaUtil_EndBufferProcessing
+ if the total input frames equals the total output frames
+
5th September 2004:
This is the first public version of the code. It should be considered
an alpha release with zero guarantee not to crash on any particular
