hi everyone,

i had started making this before i realized there were those new mp3 opcodes
(reading from mp3 was my main objective) but there are some other features in here
that may be useful to you mac users out there (using ANY frontend or commandline)

it's a "soundin" opcode that uses the OSX native soundfile reading routines.

ar1[, ar2[, ar3[, ... a24]]] soundinmac ifilcod [,itransp] [, iskptim] [, iwrap] 

it is compiled as a universal 32/64 bit binary i think it should run with any CsoundLib version.
(also included in this library is the "filevalid" opcode but that will go away with next csoundlib release)
i think you might need MacOS 10.5 or later.

let me know how it works for you
thanks,
m@


FEATURES (benefits over existing soundin/diskins)
+ automatic sample rate and channel conversion (# of outputs can be DIFFERENT than # of soundfile channels)

+ transposition may be faster than diskin2's sinc interpolation (if apple is indeed using sinc sr conversion?) 
   however, soundinmac's transposition input parameter is i-rate only :(

+ reliable, fast file streaming (file i/o is handled in another thread - well technically, with apple's new "dispatch queue" )

+ all file formats supported by the currently running MacOS (including future ones) 
 i can't find documentation from apple as to what is supported, but it probably is the same as afconvert tool
 (scroll to bottom of this text to see list of formats)


TO DOWNLOAD
http://sonomatics.com/libMacCsoundOpcodes.zip



TO INSTALL
either 
1) use the -- --opcode-lib=path/libMacCsoundOpcodes.dylib command flag
or
2) put in the /Library/Frameworks/CsoundLib.framework/Versions/5.2/Resources/Opcodes/
directory
or
3) if you use MacCsound, replace the existing dylib in MacCsound's application bundle in Contents/Resources/
  (or just wait for the next MacCsound release, in a few days)


DOCUMENTATION
soundinmac

soundinmac — Reads audio data from an external device or stream using native Mac OS functionality.

Description

Reads audio data from an external device or stream. Up to 24 channels may be read.

Syntax

ar1[, ar2[, ar3[, ... a24]]] soundinmac ifilcod [,itransp] [, iskptim] [, iwrap] 

Initialization

ifilcod -- integer or character-string denoting the source soundfile name. An integer denotes the file soundin.filcod; a character-string (in double quotes, spaces permitted) gives the filename itself, optionally a full pathname. If not a full path, the named file is sought first in the current directory, then in that given by the environment variable SSDIR (if defined) then by SFDIR. See also GEN01.

itransp (optional, default=0) -- transposition ratio (2 is an octave higher, .5 is an octave lower, etc)

iskptim (optional, default=0) -- time in seconds of input sound to be skipped. The default value is 0. 

iwrap (optional, default=0) -- if non-zero, loops to beginning of file once end of file is reached.


Performance

soundinmac is functionally an audio generator that derives its signal from a pre-existing file. Opposed to soundin, the number of output channels do not have to match that of the input file. A soundinmac opcode opens this file whenever the host instrument is initialized, then closes it again each time the instrument is turned off.

There can be any number of soundinmac opcodes within a single instrument or orchestra. Two or more of them can read simultaneously from the same external file.


Example




nchnls = 2

instr 1
	; play a stereo mp3 file an octave higher.  
	;    for demonstration purposes, this example outputs 3 channels
	;  and uses a skiptime of 20 seconds, with looping on

	al, ar, aunused soundinmac "/Users/matt/Music/cecil.mp3", 2, 20, 1 
	outs al, ar
endin

Hello Matt.

About MacCsound, frontend that I use constantly,
I have a little curiosity to meet:

because the download page http://www.csounds.com/matt/d+d.html
it stops at version 1.3b4?
Because the page is not updated to the latest version?

Thanks,
enrico

i think i posted a couple other versions but never updated that page.
anyway i'm trying to wrap up this version and get it out asap..

but barley used it :)

so is there any precedent of including a platform-specific opcode
(into canonical cvs sources, scons, and manual)?

if so, i definitely would need some hand-holding to add it to the scons file...

thanks,

Ther are non-Windos opcodes and think slike p5glove are probably linux only
Not relly a problem

happy to assist (or do the CVS stiff if that is easier)

yes, no problems there. I'm happy to help too.

OK - here is the final release for the mac-only

 "soundinmac" opcode plugin:

ar1[, ar2[, ar3[, ... a24]]] soundinmac ifilcod [, kpitch] [, iskptim] [, iwrap] 

http://sonomatics.com/soundinmac.zip

the package includes a .html documentation.

this version includes k-rate pitch shifting 
-- btw, there is noticeably less aliasing than diskin2's (sinc mode)!!!

looping seems goes out of phase fairly quickly when running side-by-side with soundin/diskin 
could be my code or apple's -- either way i probably wouldn't mix up soundinmac and diskin
with anything that is time-critical (loops or otherwise)

thanks,
matt
