Trouble with sndlplay

2013-05-24T19:48:13

Greetings!

I'm trying to learn clm library but the key program, sndplay returns with
an error:

"ALSA lib pcm_dmix.c:957:(snd_pcm_dmix_open) The dmix plugin supports only
playback stream
open pcm default for stream 1: Invalid argument
open pcm plughw:0 for stream 1: No such file or directory
open pcm hw:0 for stream 1: No such file or directory
open pcm hw:0 for stream 1: No such file or directory
open pcm plughw:0 for stream 1: No such file or directory
open pcm hw:0 for stream 1: No such file or directory"

Maybe the error is caused by the fact that my soundcard is present in the
system as device #1, not #0. So before debugging into sndlib I want to try
easier ways.

1. I've read in the documentation that by changing clm:*clm-player* I can
set an alternative player. Are there some players under Linux that support
that format?

OR

2. Maybe there is a way to change alsa device, sndlib uses by default.

Will be grateful for any help.

stop and sprout in one block

Antoine — 2013-05-21T07:18:40

Hello,

I would like to stop all running processes and then sprout the next ones
 on a single evaluation. 

(define (proc)
 (process repeat 100 do
          (print (pick 1 2))
          (wait .5)
  ))

(begin
(stop)
(sprout (proc))
)

This seems to even stop (proc) from being sprouted!
I can't use id's because it would be too much of a trouble naming 
and keeping track of all the 
processes I am sprouting each time... I just would like to "flush" 
and keep on.

Thank you for your time and your reply!

Antoine

gtk snd listener

Bill Schottstaedt — 2013-05-13T20:41:54

I'm unicodizing the gtk version of snd's listener, so if you
use the cvs stuff or the daily tarball, expect the unexpected.
I'll have it back to normal in no time...

optional arguments in Scheme

Antoine — 2013-05-09T07:30:49

Hello,

I am having a hard time understanding optional arguments 
in Scheme and could use a little help.
I want to pass optional arguments, without having to write 
the keywords and it seems that in that 
case "&optkey" becomes an argument!...


(define* (hiho a &optkey (b 0) (c 0))
  (+ a b c))

(hiho 1 12)

=> 1

(hiho 1 12 1 1)

=> 3

Neither s7 documentation nor Common Music's reference 
or examples give an overview of the syntax 
for optionals and rests arguments. Could you be kind enough 
to point me the right direction? :)
Thank you!

Installing snd and s7 on MacOS-X Mountain Lion

S7 scheme running on Android in NDK

Jason Ripley — 2013-05-03T22:17:04

Hi,

I have just added s7 scheme to a C++ project on Android, and I ran into a
couple of issues that I would like to post in case anyone else runs into
them.

1 - android doesn't seem to support the log2 function.  Easy fix:  fx =
log((double)ix)/log(2.0);

2 - It seems that arm based architectures have issues with aligned access.
I discovered this when calling s7_init to create a second scheme vm.  The
fix for this is to simply add __ANDROID__ to the __bfin__ check.


here is the diff of the changes for s7.c:

4021c4021
< #if (__bfin__)
---
10216a10217,10219
10217a10221


Are there any other spots in s7 where unaligned access may occur?  They are
rather difficult to debug.


Sincerely,
Jason Ripley

      make-formant-bank and formant-bank? (and changed formant-bank again)
      comb-bank, all-pass-bank, and filtered-comb-bank generators
      one-pole-all-pass generator moved to C
      envelope-interp, rxyk!cos, and rxyk!sin moved to C
      yet another version of oscil-bank

removed mus-file-prescaler and mus-prescaler  -- these no longer serve any purpose.

Grace,s7, system

James Hearon — 2013-04-05T16:30:24

Hi,
I'm wondering what "65280" means.

I'm trying to use the s7 "system" call from Grace,
ex.

(system "/home/Grace/test.sh")

It works fine on some things, such as if .sh contains:

#! /bin/sh
cd /opt/snd-13.5
./snd 808loop.wav

and returns 0, but on other items I just get "65280" returned in Grace.  I've checked file permissons, ownership, execution of .sh file etc.  Seems to have something to do with whether the program uses graphics or opens in a terminal.    The troublesome programs fire just fine if I directly run the .sh file from command line outside of Grace/s7.

Grace, cs:event

James Hearon — 2013-03-31T05:16:32

cs:event (list)
  
    
  
  → void




Sends an event list to Csound. The first element in the list must be the event's type, either i or f. Similar to "cs:i" and "cs:f" in all other respects. 


Hi,I hope I'm on the right list for this query. I have below using scheme, and so far so good...
(cs:i 1 0 1 440 1000)
(cs:f 1 0 1024 10 1)
but stuck here..(cs:event (list (cs:i 1 1 1 880 1000)))
I haven't been able to discover what the interpreter needs to stop bonking at me, although it does seem to write it to the console when using Audio>Csound>Export Score in spite of the error shown.
... Error: #<unspecified> is not a Csound statement type

If some kind soul has an example, I would appreciate seeing how it's done.

Regards,

samples to speaker?

Alan Grover — 2013-03-20T23:15:56

What if I wanted to algorithmically generate samples and play them on
the speaker? CM has me stumped.

First, the sound-generation should be run from the command line, so no
Grace.
Did I mention I'm on linux? Ubuntu 11.10 specifically.

Second, I'm using a genetic-algorithm to create the sound. This means I
run 100's to 1000's of times. I actually had this running in snd, but it
got all glitchy: I'm assuming memory leaks. Maybe I'll have the same
problems in cm, since it is s7 too?

Third, it doesn't have to be real-time playing, but that would be nice.
My hack for non-realtime is
(shell "aplay $myfile")
because the 'autoplay' option does nothing (in "send").

Fourth, if it isn't clear, I'm not talking midi.

I've built the command-line "cm", and played a bit with it. I can create
.wav files, for example.

Maybe CM isn't right at all? What could I use to generate sounds that I
can control/interact with other apps?

snd

James Hearon — 2013-03-16T01:04:52

Hi,I'm new to this...or rather returning after a long hiatus and trying it out again.
I have clm-4, snd-13.4, sndlib, and s7 on fedora18.  
When I type snd my.wav all I get is snd>
I must need something else to see those lovely graphics shown in the manual?

woodwind diagram?

Jeffrey Trevino — 2013-02-17T02:26:28

Hi there,

I'm studying various systems' abilities to automate the creation of
woodwind fingering diagrams (as is common in multiphonic notations). I
would very much appreciate if someone might post a minimal working example
of how I can do this with CM.

cheers,
Jeff

compiling snd on freebsd

\js — 2013-02-13T21:45:55

hi

i'm trying to compile snd on freebsd. it's not working.
i grabbed the latest sources from cvs off of sourceforge today, and ran 
this command:

configure --with-no-gui --with-oss

freebsd uses OSS for sound. there was a comment in the README.Snd that 
the oss was not tested in a long while [or something like that] ...

anyway, configure ran fine.

   Options selected
   -------------------------
   Snd version ...........: 13.5
   CFLAGS ................: -O2 -I. -g -O2
   LDFLAGS ...............: -Wl,-export-dynamic
   LIBS...................: -lc -lm  -lm -lm
   prefix.................: /usr/local
   extension language.....: s7
   audio system...........: OSS
   graphics toolkit.......: None
   optional libraries.....: fftw3 gsl
   random features........:
   environs...............: i386-unknown-freebsd9.1 gcc

but then when compiling i got this:
gcc -c -DSCRIPTS_DIR=\"/usr/local/share/snd\" -DHAVE_CONFIG_H   -O2 -I. 
-g -O2   -I/usr/local/include   -I/usr/local/include snd-file.c

independent transposition of pitch and timbre in snd

labyrinthus cochlearis — 2013-02-06T11:37:11

hi list,

i'd like to do independent transpostions of pitch and timbre (for
pitch-shifting recorded voices) - does snd have a function for this?

all the best,
chris

Snd 13.4

clm+s7 is finally up to speed -- I think it is as fast as
  the old run macro version.  This took about twice as long
  as I expected.

checked: gmp 5.1.0, sbcl 1.1.3|4, FC18 (gcc 4.7.2).

Snd 13.3

Bill Schottstaedt — 2012-12-25T19:43:16

Snd 13.3

Adam Sampson added DESTDIR support to the makefile.
removed rtio.scm.   
removed all the clm safety stuff (*clm-ouput-safety*, mus-safety etc).
as always, Mike Scholz and I made a bazillion improvements!

Checked: sbcl 1.1.1|2, cmucl 20d, gtk 3.7.2|4, fftw 3.3.3

LTAS with snd?

2012-12-03T11:35:46

Hi.

Has anyone some code for snd or clm doing a LTAS (average spectrum of
whole sounds)?  

I guess it shouldn't be too heavy to do, but if its out there already...

Cheers,

-anders
