     Their idea of "support" is quite interesting. A list of the Microsoft
Basic functions they DONT support takes over a full page just to list. The
approach to any sort of DSP calculation is interesting too. The ONLY numeric
format they support is double precision floating point. Can you say "slow as
molasses"? Oh, you can do a single precision FFT if you like. Just be ready to
write it low-level yourself!!

       Be forewarned. Their idea of support is quite loose. Be prepared to
essentially learn a whole new language, regardless of the initial model.

Summary: How do you read small chunks from the Sun audio device?
Organization: University of Minnesota
Date: Thu, 19 Nov 1992 19:16:15 GMT

Sorry to waste bandwidth, but I don't know the proper place to post
this question.

We are using the Sun audio device by opening it (sometimes blocking,
sometimes nonblocking-- it's irrelevant for the question).  We use a
read call:

count = read(record_fd, sound_bytes_ptr, sound_bytes_left);

where record_fd is the file descriptor of the sound device opened
for recording, sound_bytes_ptr is a pointer to the 0th element of
an array of chars, and sound_bytes_left is usually 800.

The very first call seems to return a small number of bytes (5 or 6).
After that, it always returns data in multiples of 1K.  I read the
audio man pages, looked in Sun documentation, tried fstat(), and I
just cannot seem to find why the device returns chunks in multiples of
1K.  It is important to us to be able to get smaller chunks.  Does
anyone know how to do this?

Thanks for your time.

  Perhaps the simplest way is to provide two bandpass filters,
one for the low frequency tone group and the other for the
high frequency group, and count zero crossings to determine
the frequency of the tone in each passband.  The tone frequencies
are (if I remember right) 697, 770, 852, 941 for the low group
and 1209, 1336, 1477, 1634 for the high group.
  A much better way is to supply a +/- 1.5% bandpass filter
for each tone frequency.  The filter outputs (of the two tones
or of the high and low band) should be within 8 or 10 db of
each other, else it is a reject.  Also it is a good idea to
compare with the band from 350 to 620 Hz to differentiate
from progress tones and speech.  An amplitude threshold at
about -35 dbm will reject false alarms from background noises.

Consider the McClellan-Parks algorithm for optimal FIR design. You can find
implementations in a lot of packages, including the original from (I think)
1973 in the IEEE transactions. Else, Matlab's Signal Processing Toolbox has
one, albeit with less information concerning the filter returned than in the
original.

Recently we got some results on the computation of continuous wavelet

Shensa algorithm which generalizes
the Mallat algorithm by applying DWT to a prefiltered sampled signal
instead of sampled signal directly. We formulated the optimal
prefilter in terms of a signal or a class of signals
such that the error between the computed and the desired ones is

The namespace for System V message queues is disjoint from the file  
descriptor namespace. They do not work with select and hence do not fit into  
ATK interaction model. In short the SysV message and shared memory  
interfaces are evil crud which never should have been implemented in a UNIX  
kernel. Use the BSD send and recv calls instead. Or if you have SysVr4, you  
might try putmsg and getmsg on streams but I'm not sure how that stuff  
interacts with select. (And it undoubtedly depends on the particular version  
of UNIX you are running.)

Unfortunately zip is not really designed for what most people want it
for...  It's primarily a hierarchical drawing editor/viewer.  (Basically
meaning that it lets you make/look at a drawing at various levels of
detail.)

To avoid the whitespace there are two things you must do.  First , make
the drawing occupy the entire visible space of the zip while the
composition tools are in place.  Second, resize the inset in browse mode
until you are satisfied.  (The month object apparently wants to be

On what *kind* of streams?  (I.e., STREAMS is a general framework; to do
IPC on top of it, you need some particular thing that plugs into that
framework.  There's probably something in SVR4 that'll do....)

>but I'm not sure how that stuff interacts with select.

"select()", in SVR4, is implemented atop "poll()", so anything that
supports "poll()" - which should include anything implemented atop
STREAMS - should work with "select()", modulo bugs in the "select()"
implementation.

I would like to use message queues with ATK and ADEW.

- is it possible to use the usual msgrcv and msgsnd in an
infinite loop ? I have tried to put an infinite loop in the
"controller_go" of an Adew view-controller, but it disturbs the
usual functionnning of the controller.

- does an object-oriented function (a sort of "im_AddMessageQueue")
exist to set an input handler when something arrives on a
message queue, just as it does for sockets in im_AddFileHandler ?

In short, is there a way I can use message queues, or can I use 
only sockets to communicate with other processes ?
