Snd is made by Bill Schottstaedt.

There's also k_guile from 2004, that still compiles:
https://github.com/kmatheussen/k_guile
Don't know if it still works though.

Guess there are other alternatives as well, but they all probably
suffer a bit from gc non-rt performance. To fix this I later extended
the code from k_guile to run in a separate thread to avoid cpu spikes,
but this code was only added to the snd sound editor (when snd was
compiled as a pd external), and that code was probably removed from
snd when switching from guile to s7.

Yes, loops are usually defined as "Loop Start" and "Loop End" cues,
but they can also theoretically be placed in the "smpl" chunk:

Hmm, or maybe they are usually defined in the "smpl" chunk, I don't remember...

But here's the code to get loop data from a wav file in radium:
https://github.com/kmatheussen/radium/blob/master/audio/Sampler_plugin_wav_parse.c#L253

First it checks if there is a loop in the "smpl" chunk. If there isn't
loop data there, it checks for "Loop Start" and "Loop End" cues.

Jack is supposed to still work under 10.15, it's just the Jackpilot
program (32 bit) that won't work anymore. You can still run jack
manually from the command line. You might also try qjackctl instead of
jackpilot too.

Not only does it compile for 64 bit, the distributed binaries are 64
bit too. Only JackPilot is 32 bit.

The Ladspa version by Steve Harris doesn't look like a port. He has
just included the original code. I think the ladspa part of the gverb
ladspa plugin is autogenerated from some xml files.
You can find the same code at
https://github.com/highfidelity/gverb/tree/master/src for instance.

You could also use something else than { and }, for instance BEGIN and END,

I had the same problem when making the k_cext external.

It's shouldn't be very hard. Start Snd, load a file, select the "f"
checkbox and unselect the "w" checkbox,
open the "Transform options" window and configure it to look the way you
want.
Finally you can create an eps file by selecting "Print" in the file menu.

To do exactly the same thing as you did last time, select "Save session"
from the
options menu, and the next time you can start snd like this:
"snd saved-session.scm".

There's also ways to automate this to process several files, although I'm
not sure
what the best way would be. (I imagine using sed to replace the filename in
saved-session.scm could be one way)

Also, it's probably better to ask on the mailing list. I've cc-ed the snd
mailing list.

expr is slower since the expressions are interpreted, but in practice it
probably doesn't matter unless expr is called extremely often. Another
alternative is k_cext which compiles the expressions to C, probably making
it the fastest alternative: https://github.com/kmatheussen/k_cext

libpds uses pd-extended from 2003 though, so perhaps it's a little bit
outdated,
but it supports gui, multiple instances, almost all externals in
pd-extended,
and it has been tested a lot in Radium.

If you use libpds instead of libpd you can enable the normal pd gui, as gui.
libpds has extended libpd with show_gui and hide_gui functions.

You could use the faust version of freeverb and compile it for pd. It's

Regarding denormals, if that's the problem, shouldn't it be good enough
to compile with -fpmath=sse -msse2 and run the following code one time in
the dsp thread?

#ifdef __SSE__
#ifdef __SSE2__
#define AVOIDDENORMALS _mm_setcsr(_mm_getcsr() | 0x8040)
#else
#define AVOIDDENORMALS _mm_setcsr(_mm_getcsr() | 0x8000)

Re: [PD] freeverb~ problem

[Kjetil Matheussen]

Carl Hetherington has a good write up on denormals:
http://carlh.net/plugins/denormals.php

This is the most interesting point:

   "The P3 always has problems with denormals no matter what GCC flags or
CPU modes are used.".

So unless you want your program to function on a P3, you can safely compile
your denormal-creating program with sse math and turn on DAZ and FTZ.
You won't get any problems with denormals then.

It depends whether the OS implements priority inheritance (
https://en.wikipedia.org/wiki/Priority_inheritance).
I think Windows does something like this, not sure, and perhaps Mac OS X
too.
In Linux, you must call pthread_mutexattr_setprotocol(mutex,
PTHREAD_PRIO_INHERIT) to
get priority inheritance for your lock. Alternatively, you can just boost
the priority manually before
obtaining the lock, and unboost after releasing.

times where a realtime priority
thread has suffered, it hadn't suffered enough to cause a glitch.

 Hi,
 did anyone manage to build pd-extended for Fedora 21? I didn't (obviously,
 that's why I ask). I already installed Tcl/Tk 8.5 since Fedora 21 only
 ships Tcl/Tk 8.6. But the closest I came to a workin pd was one which
 started but in which I could not even a dac~ object could be created.


Yes, libpds is based on pd-extended and apparently runs find in fc21.
Needed this patch:
https://github.com/kmatheussen/libpd/commit/c10ff310fae8f1e7b1853b9488ce3888d491ac3d
(or simply just replace wish8.5 with wish8.6 in s_inter.c)

 Updated to the latest version but still no file called 20-intel.conf.
 Not even an xorg.conf. Closest was an xorg.conf.failsafe located in

Hi,
That sounds correct. It's not supposed to be there. Create it, and add the
content.
