-This archive contains a quick & dirty implementation of the IEEE Standard
-1180-1990 accuracy test for inverse DCT. It is not guaranteed to be
-correct ... but if you find any bugs, please let me know (by email to
-tgl@cs.cmu.edu).
-
-The test harness consists of the C program ieeetest.c and shell script
-doieee. For comparison purposes I have also supplied a copy of jrevdct.c,
-the inverse DCT routine from release 4 of the Independent JPEG Group's
-free JPEG software. (jrevdct.c is slightly modified from the IJG release
-so that it will compile without the IJG include files.) jrevdct.c passes
-the 1180 test --- or at least, this program thinks so. jrevdct.out is
-the output from a test run.
-
-Note that numerical results may vary somewhat across machines. This appears
-to be mostly due to differing results from the cosine function.
-
-
-INSTALLATION:
- Check the Makefile, change CC and CFLAGS if needed. Then say "make".
-If your C compiler is non-ANSI, you may need to change includes and/or
-function headers.
-
- To test a different IDCT routine, link with that routine instead of
-jrevdct.o. You will need to modify dct.h and/or ieeetest.c if your
-routine's calling convention is not in-place modification of an array
-of 64 "short"s.
-
-
-USAGE:
- The standard test procedure is
- doieee ieeetest >outputfile
-Expect it to take a while (almost 80 minutes on my old 68030 box).
-Each of the six passes will emit a row of 100 dots as it runs.
-
-You can grep the output for the word FAILS if you just want to know
-yea or nay.
-
-
-LEGAL MUMBO-JUMBO:
- I hereby release the test harness to the public domain.
- Thomas G. Lane, 22 Nov 1993
-
-IMPORTANT: jrevdct.c is NOT public domain, but is copyrighted free software
-(not the same thing at all). It is subject to IJG's distribution terms, which
-primarily state that if you incorporate it into a program you must acknowledge
-IJG's contribution in your program documentation. For more details and the
-complete IJG software, see the IJG FTP archive at ftp.uu.net, in directory
-/graphics/jpeg.

- * A 2-D IDCT can be done by 1-D IDCT on each row followed by 1-D IDCT
- * on each column. Direct algorithms are also available, but they are
- * much more complex and seem not to be any faster when reduced to code.
- *
- * The poop on this scaling stuff is as follows:
- *
- * Each 1-D IDCT step produces outputs which are a factor of sqrt(N)
- * larger than the true IDCT outputs. The final outputs are therefore
- * a factor of N larger than desired; since N=8 this can be cured by
- * a simple right shift at the end of the algorithm. The advantage of
- * this arrangement is that we save two multiplications per 1-D IDCT,
- * because the y0 and y4 inputs need not be divided by sqrt(N).
- *
- * We have to do addition and subtraction of the integer inputs, which
- * is no problem, and multiplication by fractional constants, which is
- * a problem to do in integer arithmetic. We multiply all the constants
- * by CONST_SCALE and convert them to integer constants (thus retaining
- * CONST_BITS bits of precision in the constants). After doing a
- * multiplication we have to divide the product by CONST_SCALE, with proper
- * rounding, to produce the correct output. This division can be done
- * cheaply as a right shift of CONST_BITS bits. We postpone shifting
- * as long as possible so that partial sums can be added together with
- * full fractional precision.
- *
- * The outputs of the first pass are scaled up by PASS1_BITS bits so that
- * they are represented to better-than-integral precision. These outputs
- * require BITS_IN_JSAMPLE + PASS1_BITS + 3 bits; this fits in a 16-bit word
- * with the recommended scaling. (To scale up 12-bit sample data further, an
- * intermediate INT32 array would be needed.)
- *
- * To avoid overflow of the 32-bit intermediate results in pass 2, we must
- * have BITS_IN_JSAMPLE + CONST_BITS + PASS1_BITS <= 26. Error analysis

- - instance_init sets up the media info reader, its elements, and connects
- the deep_notify callback
- - read_with_idler resets the media info reader object,
- and sets location and flags
-
- - read_idler runs through a state machine:
- NULL - TYPEFIND - STREAM - METADATA - STREAMINFO - FORMAT
-
- - NULL: just returns find_type_pre, which moves state to TYPEFIND
- - TYPEFIND:
- - iterates as long as it can until it has priv->type

-This is a snapshot of my current work developing an audio
-resampling library. While working on this library, I started
-writing lots of general purpose functions that should really
-be part of a larger library. Rather than have a constantly
-changing library, and since the current code is capable, I
-decided to freeze this codebase for use with gstreamer, and
-move active development of the code elsewhere.
-
-The algorithm used is based on Shannon's theorem, which says
-that you can recreate an input signal from equidistant samples
-using a sin(x)/x filter; thus, you can create new samples from
-the regenerated input signal. Since sin(x)/x is expensive to
-evaluate, an interpolated lookup table is used. Also, a
-windowing function (1-x^2)^2 is used, which aids the convergence
-of sin(x)/x for lower frequencies at the expense of higher.
-
-There is one tunable parameter, which is the filter length.
-Longer filter lengths are obviously slower, but more accurate.
-There's not much reason to use a filter length longer than 64,
-since other approximations start to dominate. Filter lengths
-as short as 8 are audially acceptable, but should not be
-considered for serious work.
-
-Performance: A PowerPC G4 at 400 Mhz can resample 2 audio
-channels at almost 10x speed with a filter length of 64, without
-using Altivec extensions. (My goal was 10x speed, which I almost
-reached. Maybe later.)
-
-Limitations: Currently only supports streams in the form of
-interleaved signed 16-bit samples.
-
-The test.c program is a simple regression test. It creates a
-test input pattern (1 sec at 48 khz) that is a frequency ramp
-from 0 to 24000 hz, and then converts it to 44100 hz using a
-filter length of 64. It then compares the result to the same
-pattern generated at 44100 hz, and outputs the result to the
-file "out".
-
-A graph of the correct output should have field 2 and field 4
-almost equal (plus/minus 1) up to about sample 40000 (which
-corresponds to 20 khz), and then field 2 should be close to 0
-above that. Running the test program will print to stdout
-something like the following:
-
- time 0.112526
- average error 10k=0.4105 22k=639.34
-
-The average error is RMS error over the range [0-10khz] and
-[0-22khz], and is expressed in sample values, for an input
-amplitude of 16000. Note that RMS errors below 1.0 can't
-really be compared, but basically this shows that below
-10 khz, the resampler is nearly perfect. Most of the error
-is concentrated above 20 khz.
-
-If the average error is significantly larger after modifying
-the code, it's probably not good.

- * Resampling audio is best done using a sinc() filter.

- *
- * The immediate problem with this algorithm is that it involves a
- * sum over an infinite number of input samples, both in the past
- * and future. Note that even though sinc(x) is bounded by 1/x,
- * and thus decays to 0 for large x, since sum(x,{x=0,1..,n}) diverges
- * as log(n), we need to be careful about convergence. This is
- * typically done by using a windowing function, which also makes
- * the sum over a finite number of input samples.
- *
- * The next problem is computational: sinc(), and especially
- * sinc() multiplied by a non-trivial windowing function is expensive
- * to calculate, and also difficult to find SIMD optimizations. Since
- * the time increment on input and output is different, it is not
- * possible to use a FIR filter, because the taps would have to be
- * recalculated for every t.
- *
- * To get around the expense of calculating sinc() for every point,
- * we pre-calculate sinc() at a number of points, and then interpolate
- * for the values we want in calculations. The interpolation method
- * chosen is bi-cubic, which requires both the evalated function and
- * its derivative at every pre-sampled point. Also, if the sampled
- * points are spaced commensurate with the input delta_t, we notice
- * that the interpolating weights are the same for every input point.
- * This decreases the number of operations to 4 multiplies and 4 adds
- * for each tap, regardless of the complexity of the filtering function.
- *
- * At this point, it is possible to rearrange the problem as the sum
- * of 4 properly weghted FIR filters. Typical SIMD computation units
- * are highly optimized for FIR filters, making long filter lengths
- * reasonable.
