I think that maybe wcnt does both, all the modules process one sample at a
time, and the filters
add one sample to the array every time after processing x samples in filter
array to get average for the one output sampleM

likewise; I had a look at harmony central (fairly helpful) which concreted
realisation that I definately had not got any graspA of resonance in my
filters. I looked in eq cookbook, there were bits and pieces which I had no
more than vague notions of.

I've not had much chance to uDse ladspa. I've compiled glame to use it's
filter network, but there seems to be inputs and outputs Olacking, many are
mono, I can't read a stereo file, through a reverb and out to another stereo
Tfile, or from a stereo input on soundcard, through fx, to file, so I've
given up on glame (again), plus I don't like how it wont delete the deleted
things.
Another one I keep trying is SND. I quite like it, but have only got the
basics working, no effects etc. And I've got zero knowledge oNn scheme,
guile whatever. I need to get motif again as I deleted it along with
lesstif, and seemE to have lost cdrom....snd was not loading xm.
no idea what this means: above fs/4 IIRC -- not too worried about it
either.
Well, I guess I'll try and learn from otheTrs code at long last, and nip on
over to musicdsp.org.
I remember last year I somehow had a strange notion there was not much more
I could do to wcnt, and this year after a long break, everything's coming
out of the woodwork, and there's all sorts needing lifts and tucks.

New features in 2.2 since 2.0
*****************************
* Setting `raggedlast = ##t' in the `\paper' block causes the last
line to be set flush-left instead of justified.
* The `Timing_engraver' now sets the `Timing' alias on its
containing context automatically.
* The code for font selection has been rewritten. In addition to
existing font selection properties, the property `font-encoding'
has been added, which makes the switch between normal `text' and
other encodings like `braces', `music' and `math'.
* The pmx2ly script has been removed from the distribution.
* Pedal brackets will now run to the last bar of a piece if they are
not explicitly ended.
* Context definitions now use the word `\context' instead of
`\translator'.
* Property functions may be used as an argument to `set!', for
example
(set! (ly:grob-property grob 'beam) ... )
* In anticipation of Emacs 21.4 or 22.1, the info documentation
contains images.
* Cue notes can be quoted directly from the parts that contain them.
This will take into account transposition of source and target
instrument. For example,
\addquote clarinet \notes\relative c' {
\transposition bes
fis4 fis fis fis
}
\score {
\notes \relative c'' {
c8 d8 \quote 2 oboe es8 gis
}
}
* The transposition of an instrument can be specified using the
`\transposition' command. An E-flat alto saxophone is specified as
\transposition es'
* The naming of exported Scheme functions now follows Scheme
conventions. Changes be applied to Scheme files with
convert-ly -e -n --from=2.1.24 --to=2.1.26 *.scm
* Notes can be excluded from auto-beaming, by marking them with
`\noBeam'
c8 c \noBeam c c
will print two separate eighth notes, and two beamed notes.
* Translators and contexts have been split. The result of this
internal cleanup is that `Score' no longer is the top context;
`Score' is contained in the `Global' context. Consequently, it is
possible to tweak `Score' as follows:
\context Score \with {
...
}
* The number of staff lines in Tablature notation is now
automatically deduced from the `stringTunings' property.
* The program reference has been cleaned up and revised.
* The syntax for setting properties has been simplified: the
following table lists the differences:
(old) (new)
\property A.B = #C \set A.B = #C
\property A.B \unset \unset A.B
\property A.B \set #C = #D \override A.B #C = #D
\property A.B \override #C = #D (removed)
\property A.B \revert #C \revert A.B #C
Furthermore, if `A' is left out, the bottommost context is used by
default. In other words, it is no longer necessary to explicitly
mention `Voice', `Lyrics' or `ChordNames'.
Old:
\property Voice.autoBeaming = ##f
\property Staff.TimeSignature \set #'style = #'C
New:
\set autoBeaming = ##f
\override Staff.TimeSignature #'style = #'C
* Tweaks made with `\override' and `\revert' no longer hide tweaks
at higher context levels.
* Melismata in lyrics are also properly handled in the MIDI output.
* The lilypond-book script has been rewritten. It is shorter,
cleaner and faster. The special construct `mbinclude' has been
removed, plain `@include' or `\input' can be used now.
It now supports running convert-ly on the lilypond snippets,
lilypond-book --filter='convert-ly --from=2.0.0' my-book.tely
* The `LyricsVoice' context has been removed. Lyrics should only be
constructed in `Lyrics'.
* The `Thread' context has been removed. Note heads and rests are
now constructed at `Voice' level.
* Harmonic notes can now be entered as
<c' g''\harmonic>
* Drum notation is now supported as a regular feature: percussion
may be entered in `\drums' mode, and printed or performed in a
`DrumStaff' context:
\score {
\drums \new DrumStaff { hihat4 cowbell8 }
}
* The automatic staff changer was internally rewritten. As a result,
the syntax has been simplified as well:
\autochange THE-MUSIC
* The ergonomic syntax of `\markup' now has an equivalent in Scheme.
The `markup*' macro creates such objects; the following two markup
commands are equivalent:
f4^#(markup* #:raise 0.2 #:bold "hi")
f4^\markup { \raise #0.2 \bold hi }
* Voice names, for vocal lines, have been added. They are similar to
instrument names. They can be set by defining `vocalName' and
`vocNam'.
* Safe mode has been reinstated for lilypond. When lilypond is
invoked with `--safe-mode', TeX and PostScript file output is
disallowed, and lilypond-bin is invoked with `--safe-mode', the
user's Guile expressions are evaluated in a safe environment and
file inclusion is not allowed.
Warning: this does not protect against denial-of-service attacks
using Guile, TeX or PostScript.
(This feature is still experimental.)
* There is now a Scheme macro for defining markup commands. Special
mark-up commands can be defined in user-files too.
* Many fixes for dimension scaling have been made, resulting in
correct results for scores that mix staves in different sizes.
* Improved robustness when layout properties are accidentally
removed.
* A more cleanly constructed part combiner has been installed. It
is more robust and less buggy. The part-combiner can be used with
\partcombine MUS1 MUS2
See `input/regression/new-part-combine.ly' for an example.
* Formatting of rehearsal marks has been improved. The `\mark'
command now only does automatic incrementing for marks specified as
integer. For example, `\mark #1' will print an A in the default
style. See `input/regression/rehearsal-mark-letter.ly',
`input/regression/rehearsal-mark-number.ly'.
* Formatting of ottava brackets has been much improved.
* Objects in the output can now be documented: the following fragment
boxes the note head, and adds the text "heads or tails?" three
spaces below the box.
\context Voice \applyoutput #(add-balloon-text
'NoteHead "heads, or tails?"
'(0 . -3))
c8
* Default staff sizes are now scalable. There are two new mechanisms
for setting staff sizes. Both are demonstrated in this fragment:
#(set-global-staff-size 15)
\paper {
#(paper-set-staff-size (* 15 pt))
}
Both have the same effect on the global layout of a piece.
Similarly, the paper size may be changed as follows
#(set-default-paper-size "a4")
\paper {
#(set-paper-size "a4")
}
* Warnings for bar check errors are more cleverly printed. This
makes `barCheckSynchronize' superfluous, so it is now switched off
by default.
Warning: this will cause problems in scores that use bar checks to
shorten measures.
* The black note head was made a little rounder, which causes a less
frantic graphic impression.
* A more concise syntax for checking octaves was introduced. A note
may be followed by `='QUOTES which indicates what its absolute
octave should be. In the following example,
\relative c'' { c='' b=' d,='' }
the d will generate a warning, because a d" is expected, but a d'
is found.
* There is a new mechanism for putting lyrics to melodies. With
this mechanism, `Lyrics' lines can be put melodies individually,
allowing for different melismatic sections in every `Lyrics'. See
`input/regression/lyric-combine-new.ly'.
* Bar lines may now be dotted.
* The documentation now has links to a wiki, where everyone can add
personal comments to the manual.
* Contexts may now be changed locally for an isolated music
expression. For example,
\new Voice \with {
\consists "Pitch_squash_engraver"
} {
c'4
}
* The syntax for changing staffs has changed. The keyword `\change'
should now be used, e.g.
\change Staff = up
* Features of spanner contexts, like `Staff', can now be changed
using `\set', eg.
\new Staff {
\override Staff.StaffSymbol #'line-count = #4
c'4
}
puts a quarter note C on a staff with 4 lines.
* Multi measure rests are now truly centered between the
clefs/barlines of the staff, their position is independent of
symbols on the other staffs.
* Collision resolution for dots in chords has been improved greatly.
* Spacing following barlines was improved for widely stretched lines.
* Lyric hyphens and extenders now conform to standard typesetting
practice.
* Lyrics are now aligned under note heads conforming to engraving
standards. The responsible code has been rewritten, and is
drastically simpler from the previous version. To aid this
rewrite, the syntactic function of the extender line ( __ ) has
been changed: it is now attached to the lyric syllable.
* When redefining a context, the associated identifier is also
updated. For example, after reading the following snippet,
\translator {
\ScoreContext
autoBeaming = ##f
}
the definition of `ScoreContext' is updated to include the changed
setting.
* The weight of the stafflines is now heavier at smaller staff sizes.
The font has been modified to match this look: at smaller sizes,
the font is heavier and the note heads are more rounded.
* Processing scores is now done while parsing the file. New Scheme
functions give more flexibility: for example, it is now possible
interpret a score, collecting synchronized musical events in a
list, and manipulate that information using inline Scheme. For an
example, see `input/no-notation/recording.ly'.
* Font sizes can now truly be scaled continuously: the `font-size'
is similar to the old `font-relative-size', but may be set to
fractional values; the closest design size will be scaled to
achieve the desired size. As a side-effect, there are now no longer
limitations in using smaller fonts (eg. grace notes) at small staff
sizes.
* Stem tips are now also engraved with rounded corners.
* The placement of accidentals on chords and ledgered notes is
improved.

Hi,
Because I subscribed to linux-kernel recently, so I didn't get the patch after the cmpci.c posted (A user posted it). The driver after 6.0 has added kernel patch so I posted patches based on my CVS from them.
To me it is easier to keep one version for kernel 2.4 and 2.6, with a few patches, that keeps driver functions consistent.
I can post changes since my 5.64 (current version for kernel 2.6) and to 6.16 (kernel version for kernel 2.4) and the diff file of 5.64 of mine and the kernel.
Sincerely,
ChenLi Tien

To what kernel do these patches apply? Certainly not current 2.6.
If you intend to raise 2.6 patches, please ensure that they are against the
latest kernel.org kernel. And please ensure that the patches are in `patch
-p1' form. The headers should look like:
--- a/sound/oss/cmpci.c 22 Mar 2004 17:07:02 -0000 6.64

Also, a single patch per email is preferred.
Thanks.

Hi
Could anyone explain how I should go about killing a potensially
unresponsive thread? Of course there's pthread_cancel, but I don't wish to
wait for the other thread to reach a cancel point. Basically I'm trying to
implement a watchdog for a realtime audio thread. Any suggestions are
welcome, thanks.

ah, thanks for drawing the curtains. may i suggest a solution?
(background: i'm working on a similar project, which revolves
around C++ for RT audio, but also allows 'soft-RT' python audio.)
i've decided not to mess with either python locking or its memory
allocator. instead, an asynchronous scheme is employed: C++ RT audio
callbacks write to a lock-free FIFO and signal there is sample data to
process (this is done by writing a trigger to a UNIX pipe on which the
python audio thread sleeps). a second FIFO holds the results of python
audio processing. the callback code doesn't wait for the python DSP
code to complete, instead it fetches processed data from the second
FIFO right away and returns to Jack/PA/the LADSPA host/your native
audio code. all this is possible without acquiring any locks.
of course, this introduces latency in the signal path (at least one
cycle worth). otoh, the scheme runs free of dropouts, especially if
latency is allowed to span multiple audio cycles, and is compatible
across python versions.

SuperCollider sure is a nice design. unfortunately it's not using
python. :)
yet, making python RT-friendly really is too daunting a task for a
feeble mind like mine.

2.1.35 is out. It contains a great number of bugfixes, and a small
feature addition:
Setting `raggedlast = ##t' in the `\paper' block causes the last
line to be set flush-left instead of justified.
This release should be considered as the first LilyPond 2.2 release
candidate! Please test this release to check if your scores come out
OK.
I would like to request proofreaders to take a look at the chapter
"Changing defaults." Parts of this chapter have been rewritten
recently, and haven't been scrutinized closely yet.

Hi,
I update the 46.diff, which is used to patch cmpci.c to support kernel 2.6.
The synchronize_irq() has one parameter in kernel 2.6 and none in kernel 2.4, however, it still compile well on a i386 kernel 2.6, I discover it on an IA64 system.

Subject: ANN: cmpci 6.64 released
Hi,
I made many changes for cmpci.c since last release. Changes are made as follows:
1. Fix the S/PDIF out programming bug appeared in 6.16.
2. Support 8338 4-channel playback.
3. S/PDIF loop can be used after AC3 playback.
4. Legacy devices (FM, MPU401 and gameport) are served by other modules.
Now the code is thinner.
5. Remove parameters setting from kernel configure menu, they can be
set easily when loading the module.
6. Add spdif_out to output 44.1K/48K 16-bit stereo to S/PDIF out.
7. Add hw_copy to duplicate audio of front speakers to surround speakers.
8. Change code to minimum patch for kernel 2.6.
The attached cmpci.c in cmpci-6.64.tar.bz2 is the updated driver, and 46.diff is the patch file that needed for kernel 2.6.
The cmpci-patch-2.4.25.tar.bz2 and cmpci-patch-2.6.4.tar.bz2 are patches for kernel 2.4.25/2.6.4 tree patch, they are needed to support legacy devices, otherwise you may ignore them.
The cmi8738.tar.bz2 contains CMI8738, which is modified from CMI8338. It describe the parameters cmi8738 can support.
Please feedback if you have any question, I will post to kernel maintaner if no serious problem with it.
Sincerely,
