[Audiere-users] FW: Help with Audiere Installation on Windows7

[Quaki G. <qu...@li...>]

Hi 

Generally new to python, I am in quandary trying to install Audiere on python 2.7 on Windows7 environment.

I have downloaded the zipped folder audiere-1.9.4-win32 from:
http://kaz.dl.sourceforge.net/project/audiere/audiere/1.9.4/audiere-1.9.4-win32.zip

The unzipped installation folder contains the following folders:
-bin-bindings-doc-include-lib
However there is no install file as we generally encounter for other python packages

The Bindings folder includes a file called audiere.pyd and an installation instruction which says:

Into the Windows distribution of Python 2.2: Copy audiere.dll and audiere.pyd into your Python22 directory (or perhaps Python22/DLLs, depending on your system).

I tried copying both files to:

-python 2.7/-python 2.7/DLL-python 2.7 /LIb/site-packages/ directory 
But

import audiere 

still gives an import error:

Traceback (most recent call last): File "", line 1, in import audiere ImportError: DLL load failed: The specified module could not be found.

I hope this is nothing to do with python 2.2 versus python 2.7 because people have successfully used audiere on 2.7 without any modification.

Any help on installing Audiere on Windows7 would be greatly appreciated.

regards
Quaki Gabbar

[Audiere-users] State of the Library?

[The D. J. <the...@gm...>]

Is this project still worked on?  Last I recall it had no support for ALSA
in Linux, and no Mac OS X support.  Have these changed?

[Audiere-users] Does anyone have an easy to follow guide to installing pyaudiere in linux?

[Johannes V. <neb...@ho...>]

Hi folks,

I've been using pyaudiere with great success in a hobby project of mine on windows XP. My preferred OS is ubuntu, but everytime I want to install pyaudiere on an ubuntu machine I run into trouble. The main reason for this is, that I am not a computer wizzkid and the guide to installation is unfortunately very poor/non-existant (sorry if I offend anyone with this).

I couldn't use the .deb on the website since it is for python2.5 and python2.6 is standard nowadays for ubuntu so I was stuck there also.

Could someone maybe write a brief HowTo for the installation from source for pyaudiere (and post it on even on the website)? I hate to see such a great library not being used simply because it cannot be installed :(

I thank the person for the effort. It is greatly appreciated.

Thanks again,

Johannes

Looks like you need to include string.h in some files.  Commit the fix
when you're done?  I can give you commit access to the project.

No suggestions anyone?

I noticed this same question asked but not answered back 
in May.  Is audiere still a viable project?

[Audiere-users] install problem on fedora-11

Hello,

I am trying to install audiere-1.9.4 (needed for PyAudiere)
on a Fedora-11 machine.  I ran configure (it warned about some 
missing optional (I think?) libs [*1] but was otherwise ok.

When I ran "make", I got:

Re: [Audiere-users] chad, i need really your help and a quick look at audiere

[christoph g. <kar...@ya...>]

hum....
thanks, i can list Direct Sound and winmm.
but still teh same problem, when trying to connect to direct sound, it 
doesnt initaialize the device. only winmm.

as suggested by Chad ( recompile audiere project on VC to obtain working 
dll and lib),  i don t arrive to make it compil on Visual C++ 2010 free 
edition.
there are many importations to do , and there seems to be quite a mess 
around dependencies.
as i m not at all a VC user, does anyone around has .lib and .dll from 
audiere 1.9.4 already compiled for windows? (sources from audiere site 
are not working, i have the same issue)

yours, christoph

[Audiere-users] whitecat lighting board

[christoph g. <kar...@ya...>]

whitecat lighting board is a proffessionnal application for lighting in 
dance and theatre. Its uses audiere to make sound diffusion during the show.

link: http://www.le-chat-noir-numerique.fr

Re: [Audiere-users] chad, i need really your help and a quick look at audiere

[Brian R. <va...@ho...>]

You can always do:

void ShowSupportedAudioDevices()
{
  std::vector<audiere::AudioDeviceDesc> devices;
  audiere::GetSupportedAudioDevices(devices);

  for (unsigned int i = 0; i < devices.size(); i++) {
    print("%s - %s\n", devices[i].name.c_str(), devices[i].description.c_str());
  }
}

But generally there's "directsound", "winmm" and "null"

Re: [Audiere-users] chad, i need really your help and a quick look at audiere

[Chad A. <ae...@ae...>]

I don't exactly remember.  I think maybe it's
OpenDevice("directsound"), but DirectSound may not be available if
you're compiling with mingw.  You may want to try Visual Studio.

+audiere-users: any other ideas?

Re: [Audiere-users] Output to a file

[Chad A. <ae...@ae...>]

If you can build Audiere from source, you should be able to derive
from audiere::MixerDevice and write to a wav file.  They're pretty
simple files.  That would be the approach I'd take.

[Audiere-users] streaming media

[Brian R. <va...@ho...>]

Probably a question for Chad...

I've got code to play streaming files in audiere...
But it's kind of intermingled with my own webserver project so it's not really in a state to be submitted to sourceforge...

So the question - what library should I switch the streaming code over to use?
Any preferences?

libcurl?


Also would you want streaming media support in audiere for it to be worthwhile me doing this?


 		 	   		  

Re: [Audiere-users] Output to a file

[Brian R. <va...@ho...>]

I'm not sure how you'd do this in C# - but probably make it in C++ and then DllImport it into C# (making sure you use extern "C" to avoid name mangling)...

But here's the possible C++ solution (maybe) - or at least it's an idea to try is to inherit from (or wrap) audiere::OutputStream or audiere::SampleSource

I've not tried that - but I once made my own audiere:StreamingFile by inheriting from audiere::File and implementing read()/seek() methods via http - so it's probably possible.

---------------------------------------------------------------------------------------

As a side note - I'm amazed my streaming code still compiles and still works...

[Audiere-users] troubles to read correctly speed and framerate

[christoph g. <kar...@ya...>]

hi? i m using audiere on windows and i m facing troubles to detect on a 
single wav or mp3 file the sampling rate.

has anyone a piece of code showing how to get this information ?

I noticed also that on preloaded files, little wav will have troubles to 
be read correctly if there is someome of different framerate preloaded.

yours,

[Audiere-users] Output to a file

[Tom W. <t.d...@su...>]

  Hi all,

Been using Audiere successfully in a project for several months now and 
am very happy with it.

Just wondering if it's possible to write the output to a file? Can it, 
for example, generate an MP3 or WAV file?

Alternatively, is there a way to capture the output and route it to a file?

It'd suck to have to rewrite everything just to match new requirements!

Thanks,
Tom

Re: [Audiere-users] Does Audiere also play audio streams from memory?

[Brian R. <va...@ho...>]

I can't recall whether it has built-in support to do this
But I did have it playing ogg's via http ages ago so what you want to do should be possible

(I did something like read data from a http stream - put the data into a byte array and get audiere to play the byte array.)

So basically my code implemented audiere::StreamingFile interface like so:

class CHttpStreamingFile : public audiere::RefImplementation<audiere::StreamingFile>
{
    int ADR_CALL read(void* buffer, int size)
    {
       int num_bytes_read = 0;


       // read 'size' bytes of data from your container and place it into 'buffer'

       // then return the number of bytes read, which should be size or less
       return num_bytes_read;
    }

    bool ADR_CALL seek(int position, SeekMode mode)
    {
      bool can_seek = false;
      return can_seek;
    }

    int ADR_CALL write(const void* buffer, int size)
    {
      return 0;
    }

    int ADR_CALL tell()
    {
        return 0;
    }
}

- So you might be able to do something similiar?

[Audiere-users] Does Audiere also play audio streams from memory?

[Markus L. <m.l...@av...>]

Hey,


I found some nice examples of Audiere at 
http://gpwiki.org/index.php/Audiere:Tutorials:Introduction but I don't 
know if it's also possible to play audio data from a memory position, 
ie. without giving a file pointer? I have my own audio container and 
additionally the data is G.711 encoded so I cannot give a file pointer.

I also need to play multiple audio streams *at the same time*. These are 
mono speech recordings and have a lot of silence so there should not be 
an acoustic problem playing them simultaneously. Does Audiere provide a 
possibility to play multiple streams? Or do I need to implement my own 
mixer (I've read that the streams just need to be added together...)?

[Audiere-users] Compiling libaudieresharpglue for the C# bridge

[Tom W. <T.D...@su...>]

(Apologies for cross posting - wasn't sure which was best.)

Hi all,

I'm having major problems compiling libaudieresharpglue (part of Harald 
Fielker's C# bindings).

I've opened the project up in VC++ Express 2008 and set the Include and 
Library directories to point at the appropriate directories within 
"audiere-win32" and yet I still get errors like these:

    ..\src\outputstream.cpp(8) : error C2065: 'OutputStream' :
    undeclared identifier
    ..\src\outputstream.cpp(8) : error C2065: 'stream' : undeclared
    identifier
    <snip!>
    ..\src\audiodevice.cpp(124) : error C2065: 'AudioDevice' :
    undeclared identifier
    ..\src\audiodevice.cpp(124) : error C2059: syntax error : ')'
    ..\src\audiodevice.cpp(125) : error C2065: 'device' : undeclared
    identifier
    ..\src\audiodevice.cpp(129) : error C2065: 'device' : undeclared
    identifier
    ..\src\audiodevice.cpp(129) : fatal error C1003: error count exceeds
    100; stopping compilation

Anyone out there know why this might be happening? I feel like I'm 
missing something fundamental.

Regards,
Tom Wright

Re: [Audiere-users] C# wrapper

[Tom W. <T.D...@su...>]

Hi list,

Bob Pfingsten: You can download the wrappers here - 
http://sourceforge.net/mailarchive/forum.php?thread_name=200710271451.41075.harald.fielker%40web.de&forum_name=audiere-devel

Unfortunately, I'm unable to compile libaudieresharpglue.dll. Does 
anyone have the compiled DLL that I could grab?

Thanks,

Tom

[Audiere-users] Undesired looping of streams

[Richard A. <ri...@co...>]

Hi,

I'm having a problem with Audiere. When I try to play a streamed sound 
all I get is an infinite loop of the first couple of seconds. Tried ogg 
(vbr and cbr), mp3, wav, always the same result. I'm using the 1.9.4 
binary directly from the site and followed the tutorial. The code 
(below) seems pretty straightforward... Do anyone know what the problem 
could be?

AudioDevicePtr device(OpenDevice());
if (!device) {
// failure
}

OutputStreamPtr stream(OpenSound(device, "Theme.ogg", true));
if (!stream) {
// failure
}

stream->play();
