Subject: <Sound Dev> A Java Sound Mixer Service Provider Implementation with
	PortAudio
Message-ID: <F8CBD86B-AA3E-4AD2-A1A7-A778BAAA14F2@inprinciple.org>

Good Day,

I was able to implement a basic Java Sound Mixer Service Provider  
with PortAudio.
TargetDataLine and SourceDataLine are working.

I read the posting that the OpenJDK implementation is going to be  
released soon.
But I guess it is not to mean for Mac OS X.
So I thought it may be of interest to OpenJDK community.

I was able to record and playback at sampling rates from 2 kHz to 96  
kHz on MacBook.

I call my implementation YavaSound to make it sound close to Java  
Sound and also to distinguish it from Java Sound. If this name is not  
allowed for legal issues (trade name,.. etc), please let me know, I  
can change it to something else.

The source code is under same license as PortAudio (www.portaudio.com).
YavaSound source can be downloaded from :
http://YavaSound.inPrinciple.org/YavaSoundSource.zip

The PortAudio library used is for Mac OS X.
But as PortAudio is cross platform.
Making YavaSound cross platform is easy as linking to corresponding  
PortAudio library.

Best Regards,
Yong

Hi Yong,

that's a nice thing to have!

YavaSound is very similar to the original name, in some languages
it will even sound the same as JavaSound (e.g. in German), so in
order to be on safe side, legally, I'd recommend to name it
differently though.

Also, your name is not very descriptive. Maybe a name that
includes or references somehow "PortAudio" will tell people
already from the name what it will do. Or a fantasy name...

Regards,
Florian

Hi Florian,

Thanks for the advice.
Maybe I should look for a new name, but I do not know what to call it 
otherwise yet.

I will just wait and see how it goes until either I get a better name for it 
or Sun says something.
Is this a bad attitude?

Regards,
Yong

Hi,

I am just wondering if I should go and implement Clip interface as well.
But if Sun is going to release the implementation source code soon and if it 
is written in pure Java without JNI, there is no point for me to implement 
it myself.
Any thoughts?

Regards,
Yong

Sun's Java Sound uses JNI internally. If you want to provide
Clips from your plugin, you'll need to implement it yourself.

not necessarily. But as far as I know the lawyers, they would
argue that *I* said something...

In any case, Sun doesn't have a history of suing.

And don't get me wrong, I like your name. But as far as I can
tell, you are "violating" their trademark. Maybe just make it
"YongSound" or "YoonSound"?

Florian

I've added LineListener implementation in Line and DataLine.
I guess most of interfaces except Port in sampled.* are taken care of now.

I think Port implementation will involve some more PortAudio.
I will see how it turns out. :)

	opened
Message-ID: <46EA710E.9000308@sun.com>

Hi all,

Sorry for several weeks delay with the event, but...
I'm glad to inform you that big part of JavaSound implementation source has been
opened and is available at the openjdk website
(http://download.java.net/openjdk/jdk7) and at the subversion repository
(http://openjdk.dev.java.net/source/browse/openjdk).

Open part includes the following:
- "direct audio" mixer implementation (DirectSound/ALSA/Solaris Audio Mixer);
- Ports mixer implementation (WinMM/ALSA/Solaris Audio Mixer);
- Midi i/o devices implementation (WinMM/ALSA);
- various file readers/writes, format converters.

Closed code has been moved into separate library (jsoundhs).

Base classes and interfaces for both open and closed implementation classes
(AbstractLine, AbstractMixer, AbstractMidiDevice, AutoClosingClip, etc.) are open.
There are still a few dependencies from "closed" classes in open code, all such
dependencies will be removed when we'll have replacement for closed part and
start replacement process.
To make JavaSound completely open (and drop closed part) we need alternative
implementations for:
1) Software synthesizer. There is separate openjdk project for the task - 
audio-engine-dev;
2) OSS mixer (for linux/solaris, both sampled and midi).

Regards
Alex

Message-ID: <Pine.LNX.4.64.0709241049360.11076@linux16.phonetik.uni-muenchen.de>

Hello,

I would like to record multi-channel 24-bit audio with the 
DirectSound JavaSound implementation under Windows. 

But the audio formats defined in

j2se/src/windows/native/com/sun/media/sound/PLATFORM_API_WinOS_DirectSound.cpp

are limited to 8/16bit and 1 or 2 channels. 

I would like to discuss how this limitation could be removed.
 
For testing multichannel capabilities of JavaSound I extended 
channelsArray up to 8 channels and bitsArray for 
24/32 bit recordings, then compiled dsound.dll and tested recording.
It worked fine, so it's a pity that the recording formats are restricted 
to basic formats.

The question is how to make multi-channel possible without changing 
the supported defaults formats, which can be queried by 
isFormatSupported(AudioFormat).

Regards,

Klaus

Hi Klaus,

It's CR 6477263: JavaSound doesn't support multi-channels on Windows
(http://bugs.sun.com/view_bug.do?bug_id=6477263)
Feel free to develop a fix for the CR :)

Why do you want to keep supported format unchanged?
Right way is to change the supported formats (line/mixer should report formats 
it really supports).

Regards
Alex

Yes good idea, but I fear building the JDK under Windows, because Sun uses 
old versions of SDK's and Compiler (I do not have VS.NET 2003 and I don't 
want to buy it at eBay). I have already build an older JDK version and it 
was horrible. (Tweaking make files and so on ...)
Is it possible to compile dsound.dll seperatly with VS 2005 Express ?

Yes, you are right. But I do not know if it is possible to get the 
supported formats from DirectSound.
I think the number of capture channels is available, but only when the 
line is open.

Klaus

Due the build doc (make/README-builds.html) "VS2005 compiler will not work at 
this time due to the new runtime dll and the manifest requirements". :(
I never used VS2005 so I don't know what it requires.
AFAIR there was some free toolkit with VS2003 c++ compiler. Most likely it 
should work.
(BTW you need to build jsoundds.dll - see make/javax/sound/jsoundds)

Yes, DirectSound does not provide information about HW capabilities (the 
detection was possible in WinMM, but I don't remember is it possible to 
determine relations between WinMM & DS devices and I'm not sure WinMM functions 
supports >2 channels).
Anyway I think due DirectSound can handle multi-channel audio, JavaSound should 
report it as supported formats (at least for playback, capturing requires 
additional research).

thanks for the hint, but I'm too late for download:
"The Visual C++ Toolkit 2003 has been replaced by Visual C++ 2005 Express Edition."
