That is the + absolute value of the difference. + + In the case of positions in 2D, 3D, etc., use the L2-Norm which is + a generalized Pythagoras' Theorem: dist^2 = x^2 + y^2 + z^2 + ... + A norm is a distance between something and zero. + + Sometimes you have several practical results for one expected value + and must extract a single absolute error out of that. Then you should pick + the largest of the individual absolute errors. + + Sometimes you don't have an expected value, you just have several + practical results that you expect to be quite the same. In that case, + the absolute error is the "diameter" of those results. The meaning + of diameter here is: the largest distance between any two results. + + If in a single test you must compare 2D errors with 3D errors and 1D + errors, etc., you may have to adjust them by dividing the error by + the square root of N (N is the number of dimensions). In that case, + the resulting value is called a RMS (Root-Mean-Square). + + The maximum error introduced by just representing a number as a float + (instead of an exact value) is at most proportional to the magnitude + of the number (e.g. usually 16 million times smaller: about 6 decimals). + Also, often we are only interested in relative error, which is absolute + error divided by the norm of the expected result, because small absolute + errors don't matter much with large results. This is the reason floats + exist in the first place. By default, use relative error as the $accuracy + in Pd tests. + + If you don't have an expected result, then compute the relative error as + being the absolute error divided by the norm of the average of practical + results. + + In the RMS case of relative error, the norms of expected results should also + be adjusted, but both adjustments cancel because they get divided by each + other. That means: don't divide by the sqrt(N) at all and you'll get an + appropriate result. + + +-+-+--+---+-----+--------+-------------+---------------------+ ETC *************** *** 120,121 **** --- 179,195 ---- if there are any, restart the tests in verbose mode and see where the error happens exactly. + + [...] + + Floating-point is the scientific notation for numbers that we all + learned on paper in school. Rounding and inaccuracy are two sides + of the same coin. They are required when it is stupid to have perfect + results, that is, when it would mean too many computations for little + gain. + + However sometimes we want to make sure that our math is accurate enough. + Many algorithms are data-recursive: each computation uses previous + results. Many of those algorithms have chaotic and/or unstable + behaviours, which means that the inaccuracies may skyrocket instead of + fading out. +

It should be considered an alpha release with zero guarantee not to crash on any particular system. So far it has only been tested in the author's development environment, which means a Win2k/SP2 PIII laptop with integrated SoundMAX driver and USB Tascam US-428 compiled with both MinGW (GCC 3.3) and MSVC++6 using the MS DirectX 9 SDK. It has been most widely tested with the MinGW build, with most of the test programs (particularly paqa_devs and paqa_errs) passing. There are some notable failures: patest_out_underflow and both of the blocking I/O tests (as blocking I/O is not implemented). At this point the code needs to be tested with a much wider variety of configurations and feedback provided from testers regarding both working and failing cases. What is the WDM-KS host API? ---------------------------- PortAudio for Windows currently has 3 functional host implementations. MME uses the oldest Windows audio API which does not offer good play/record latency. DirectX improves this, but still imposes a penalty of 10s of milliseconds due to the system mixing of streams from multiple applications. ASIO offers very good latency, but requires special drivers which are not always available for cheaper audio hardware. Also, when ASIO drivers are available, they are not always so robust because they bypass all of the standardised Windows device driver architecture and hit the hardware their own way. Alternatively there are a couple of free (but closed source) ASIO implementations which connect to the lower level Windows "Kernel Streaming" API, but again these require special installation by the user, and can be limited in functionality or difficult to use. This is where the PortAudio "WDM-KS" host implementation comes in. It directly connects PortAudio to the same Kernel Streaming API which those ASIO bridges use. This avoids the mixing penatly of DirectX, giving at least as good latency as any ASIO driver, but it has the advantage of working with ANY Windows audio hardware which is available through the normal MME/DirectX routes without the user requiring any additional device drivers to be installed, and allowing all device selection to be done through the normal PortAudio API. Note that in general you should only be using this host API if your application has a real requirement for very low latency audio (<20ms), either because you are generating sounds in real-time based upon user input, or you a processing recorded audio in real time. The only thing to be aware of is that using the KS interface will block that device from being used by the rest of system through the higher level APIs, or conversely, if the system is using a device, the KS API will not be able to use it. MS recommend that you should keep the device open only when your application has focus. In PortAudio terms, this means having a stream Open on a WDMKS device. Usage ----- To add the WDMKS backend to your program which is already using PortAudio, you must undefine PA_NO_WDMKS from your build file, and include the pa_win_wdmks\pa_win_wdmks.c into your build. The file should compile in both C and C++. You will need a DirectX SDK installed on your system for the ks.h and ksmedia.h header files. You will need to link to the system "setupapi" library. Note that if you use MinGW, you will get more warnings from the DX header files when using GCC(C), and still a few warnings with G++(CPP).
