/* For people that are looking at this source: the purpose of these defines is
* to make GstCaps a bit easier, in that you don't have to know all of the
* properties that need to be defined. you can just use these macros. currently
* (8/01) the only plugins that use these are the passthrough, speed, volume,
* adder, and [de]interleave plugins. These are for convenience only, and do not
* specify the 'limits' of GStreamer. you might also use these definitions as a
* base for making your own caps, if need be.
*
* For example, to make a source pad that can output streams of either mono
* float or any channel int:
*
* template = gst_pad_template_new
* ("sink", GST_PAD_SINK, GST_PAD_ALWAYS,
* gst_caps_append(gst_caps_new ("sink_int", "audio/x-raw-int",

View file

@ -1,48 +0,0 @@
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

* Algorithms with 11 Multiplications", Proc. Int'l. Conf. on Acoustics,
* Speech, and Signal Processing 1989 (ICASSP '89), pp. 988-991.
* The primary algorithm described there uses 11 multiplies and 29 adds.
* We use their alternate method with 12 multiplies and 32 adds.
* The advantage of this method is that no data path contains more than one
* multiplication; this allows a very simple and accurate implementation in

* 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
* shows that the values given below are the most effective.

* media-info is a library to collect metadata and streaminfo from media
files
* the current implementation is idler-based.
* you create a new media_info object
* you set the string name of a source element to use using g_object_set or
gst_media_info_set_source
* you declare you'll read a given file by using gst_media_info_read_with_idler
* you loop gst_media_info_read_idler (info, &stream) as long as it returns TRUE
and as long as stream is still NULL
* INTERNALS:
- 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
- find_type_post
- call gmi_set_mime which creates a pipeline to decode stuff
- move to STREAM
- STREAM

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.
*
*
* out[t] = Sum( in[t'] * sinc((t-t')/delta_t), all t')
*
* 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.
