uint64 -> double conversion
Anybody knows the reason for the following code (you can see it in flac/decode.c, flac/encode.c, libFLAC/fixed.c and libFLAC/stream_decoder.c) ? #if defined _MSC_VER || defined __MINGW32__ /* with MSVC you have to spoon feed it the casting */ residual_bits_per_sample[0] = (FLAC__float)((total_error_0 > 0) ? log(M_LN2 * (FLAC__double)(FLAC__int64)total_error_0 /

better seeking
Ok, the patch from 2003 about improving seeking still didn't make it to CVS, so here is another try. I made some benchmarking with the test_seeking utility from flac sources to show how bad the current seeking is, especially without seektable. Track used for the experiment had about 50 minutes. In the following table is average number of seeks and number of decoded frames required for one

better seeking
When I was trying to find yesterday's xmms-plugin bug, i have noticed that seeking in stream without seek-table isn't very good. With attached patch it is much better. -- Miroslav Lichvar -------------- next part -------------- --- src/libFLAC/seekable_stream_decoder.c.orig 2003-02-26 19:41:51.000000000 +0100 +++ src/libFLAC/seekable_stream_decoder.c 2003-07-09 23:49:35.000000000 +0200

One block in the file triggered a very rare bug in the LPC coefficient quantizer caused by insufficient floating point precision. There is a snippet to compute the log(base 2) of a number:

Single Precision (4 byte) floats with readBin
I would like to use readBin to read a binary data file. Most of the data is 4-byte floating point but, for some reason, only double precision appears to be offered. I tried fVariable=readBin(iFile,what=single()); and got 35.87879 which looks believable except that the correct value is 3.030303. I then tried fVariable=readBin(iFile,what=single(),4); and got [1] 3.831111e+10 6.657199e+10

Scanning data lines with blanks in character vars
Hello, I'm trying to read data in from a file using scan(). The last field is a character string that contains blanks. I had read it in in S-Plus using this code: ifile <- list(entry=0,measure=0,st=0,count=0,score=0, error=0,inmsq=0,instd=0,outms=0,outstd=0,displc=0,ptbis=0,a=0, r="",name="") if.widths <- c(1, 5, 8, 3, 6, 7, 7, 7, 7, 7, 7, 7, 7, 2,

[PATCH] test_compression.sh
* Use `mktemp` instead of playing with date(1). * Use -f instead of removing the file every time. * "echo ERROR; exit 1" is what die() is for. * Some cosmetic renamings ('k' to 'comp' for compression etc). * Remove the MacOSX comment. It's not MacOSX specific, and it's not a problem anyway. The number behaves just right. * Remove the $((${size}+10)). It's

Sorry, most of the testmaterial isn't copylefted, and I don't think it is possible to get a nice copylefted test library. That's because most copylefted material is indie, and sadly the mastering techniques

sqldf for Very Large Tab Delimited Files
Hi All, I have a very (very) large tab-delimited text file without headers. There are only 8 columns and millions of rows. I want to make numerous pieces of this file by sub-setting it for individual stations. Station is given as in the first column. I am trying to learn and use sqldf package for this but am stuck in a couple of places. To simulate my requirement, I have taken iris dataset as an
