[Csnd] Csound-wasm version at https://csound.github.io/wasm/

Tarmo Johannes-3
Hi,

I noticed that the Csoud-wasm version on https://csound.github.io/wasm/ is
still 6.09.
I think that it is good that there is a certain place in web where you can
link to Csound-wasm recources like
<script src="https://csound.github.io/wasm/js/libcsound.js"></script>
<script src="https://csound.github.io/wasm/js/CsoundObj.js"></script>
and get the latest version of libcsound.wasm

Or what is the best practice to use Csound-wasm on one's own sites? Should one
always download csound-wasm from download page, unzip and upload to the server
where his html file is going to be?

Thanks!
tarmo

Good question. There are several places to download it now. The Csound
repository is one. It looks to be pretty up to date with
https://github.com/gogins/csound-extended/releases/download/v0.1.0-beta2/csound-wasm-6.11.0-beta2.zip.
Have you tried this? I think it's probably good.

I have two other sources. gogins.github.io is out of date and I will fix that.

I have another version of Csound for WebAssembly at
https://github.com/gogins/csound-extended, called csound_extended.js
instead of csound.js, that is implemented slightly differently but
supports most of the same JavaScript API. Right now the main
difference is that csound_extended.js follows the semantics of the
original Csound API somewhat more closely than does csound.js. As time
goes on I will be adding features, the first will be a WebAssembly
build of CsoundAC with a JavaScript interface. I am updating this
repository fairly regularly.

Regards,
Mike

Hi,

Yes, this works nicely, thanks!

 

I think that it would be nice to have one place online where the latest Csound-wasm build can be reached, so that users don't have to always download unpack and upload the package when they want to use Csound-wasm in their page.

 

Is it now so that the libcsound.wasm file must be exmplicitly in the same folder as the user's html/javascript file? Is it perhaps possible to load it rempotely? In that case I would suggest that http://csound.com/wasm/ would be the place set link to.

Perhaps best to file an issue, either on the Csound tracker or
csound.github.io tracker. 6.11.0 should be out soon and we can publish
it to whatever URL is proposed. We could host on csound.com, but we
could also look at other CDN sites too.  (I think we might not be able
to follow CORS rules for cross-site scripting and publishing publicly
on csound.com with github pages, but I haven't looked at that kind of
thing in a long while).

The benefit of unpacking/installing as part of your project is that
you don't have to deal with CORS and can depend upon it working
always.  I think Ed's done some research into making the inclusion
automated via Webpack and Hlodver's done some research making a single
JS all-in-one file that might make things simpler. (Perhaps they could
comment on their efforts here?)

CORS is cross-origin resource sharing, which is a security risk. It is
however common, e.g. for CDNs, see https://enable-cors.org/.

Re: [Csnd] Csound-wasm version at https://csound.github.io/wasm/

Yes, I have been able to get Csound working inside of a React app using Webpack 4.

I am compiling the WASM using the following:

emcc -v -O2 -g4 -DINIT_STATIC_MODULES=1 -s SINGLE_FILE=1 -s MODULARIZE=1 -s EXPORT_NAME=\"'libcsound'\" -s DEMANGLE_SUPPORT=1  -s WASM=1 -s ASSERTIONS=1 -s "BINARYEN_METHOD='native-wasm'" -s LINKABLE=1 -s RESERVED_FUNCTION_POINTERS=1 -s TOTAL_MEMORY=268435456 -s ALLOW_MEMORY_GROWTH=1 -s NO_EXIT_RUNTIME=0 -s EXTRA_EXPORTED_RUNTIME_METHODS="['FS', 'cwrap']" CsoundObj.bc FileList.bc libcsound.a ../deps/libsndfile-1.0.25/libsndfile-wasm.a  -o libcsound.js

Notice I added the SINGLE_FILE, MODULARIZE and EXPORT_NAME option. (As an aside I don’t think it’s necessary to have the Csound_Obj exported functions anymore in the above line as someone added the Emscripten Keep Alive macro to the CsoundObj.c source).
Also using SINGLE_FILE is not necessary, and seems to be slower to load than without.

In my Webpack 4 config:

module.exports = {
    module: {
        rules: [
            {
                test: /\.js$/,
                exclude: /node_modules/,
                use: {
                    loader: "babel-loader"
                }
            },
            {
                test: /\.wasm$/,
                type: "webassembly/experimental"
            },
            {
                test: /\.csd$/,
                use: 'raw-loader'
            }
        ],
    },
    node: {
        fs:'empty',
        ws:'empty'
    },
    externals: ['ws']
}

I can then import Csound into a Javascript class like this:

import libcsound from './libcsound.js';

class MyClass {

        constructor() {

                libcsound().then((Module) => { console.log("libcsound loaded."); })
        }

}

Re: [Csnd] Csound-wasm version at https://csound.github.io/wasm/

hlolli
I made a single js, still work in progress

but this usage example shows it's simplicity

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
  </head>
  <body>
    <h5>Click Start realtime once, gotta love chrome's new autoplay ban policy</h5>
    <button id="start">Start realtime</button>
    <button onclick="csound.inputMessage('i 1 0 1')">Make beep!</h1>
    <script src="https://github.com/hlolli/csound-wasm/releases/download/6.10.0-4/csound-wasm-browser.js"></script>
  <script>
    const beeper = `
    instr 1
    asig = poscil:a(0.3, 440)
    outc asig, asig
    endin
    `
    document.getElementById('start').onclick = ()=> {
    csound.startRealtime();
    csound.compileOrc(beeper);
    };
  </script>
</body>
</html>

This will work anywhere, one can quickly try at

Re: [Csnd] Csound-wasm version at https://csound.github.io/wasm/

Tarmo Johannes-3
Great!

I think something like that would be very welcome from users point of view! If
it has no contradictions with security or else, I guess for Csound use in web
pages that would be really useful.

I saw it has a new API method csound.startRealtime(config*).
It is probably necessary to distinguish from csound.start() but I find it very
important -  if ever possible -  that all html/javascript associataed APIs
would use same or similar methods -  so the same code works in Android, Csound
For Node, Wasm, CsoundQt etc.  What do you think?

Re: [Csnd] Csound-wasm version at https://csound.github.io/wasm/

Michael Gogins-2
It's always possible to implement the existing API first and then add any new functionality that may be desired or required, with new names. 

This is what I did in csound_extended.js. I think this is the right approach. 

This does not appear to be the case with csound.js. 

Regards, 
Mike

Great!

I think something like that would be very welcome from users point of view! If
it has no contradictions with security or else, I guess for Csound use in web
pages that would be really useful.

I saw it has a new API method csound.startRealtime(config*).
It is probably necessary to distinguish from csound.start() but I find it very
important -  if ever possible -  that all html/javascript associataed APIs
would use same or similar methods -  so the same code works in Android, Csound
For Node, Wasm, CsoundQt etc.  What do you think?

Re: [Csnd] Csound-wasm version at https://csound.github.io/wasm/

Victor Lazzarini-2
No, csound.js is meant as port of the PNaCl Csound, not as an extension to CsoundObj. It is effectively a JS frontend in the same way as PNaCl Csound.

Re: [Csnd] Csound-wasm version at https://csound.github.io/wasm/

Michael Gogins-2
Tarmo: I don't think that the interface in CsoundObj.js is likely to
be changed to conform more closely to the API defined in csound.hpp,
which in turn follows csound.h very very closely.

Victor, can you confirm that?

So, if one wants such an interface that is more like csound.hpp, one
can use the interface in csound_extended.js in the csound-extended
repo, which does conform.

Victor: In case you are interested in the details they are:

Method names in CsoundObj.js are camel case, method names in
csound.hpp are initial caps. There are a few other differences.

In CsoundObj.js (and also in csound.js) calling start before compiling
the orchestra or csd does not work. Performance happens and messages
are printed, but no live audio is heard. Compiling the orchestra or
csd and then calling start works fine. I have attached a test HTML
file that demonstrates this. I believe the cause is that in
CsoundObj.js, _prepareRT is always called within the body of
compileOrc etc., when perhaps it should be called in start. Would
changing this break backwards compatibility with examples etc.?

Both sequences work in csound_extended.js.

The interfaces in csound.node and the Csound for Android app are quite
close to csound_extended.js and a lot of the same pieces run in all
these environments.

Regards,
Mike

Re: [Csnd] Csound-wasm version at https://csound.github.io/wasm/

Victor Lazzarini-2
I do not think the API will change in the case of CsoundObj, but if it does, it is Steven’s decision,
since he originated the design and wrote most of it.

It is possible, however, if anyone has the time and patience to do it, to write a JS version
of the Csound API that wraps the C or C++ functions more closely. I don’t know how
useful that would be, since all the interfacing with Web Audio etc will have to be done
outside it. But I guess it would give a lower level access to libcsound WASM.

Re: [Csnd] Csound-wasm version at https://csound.github.io/wasm/

Steven Yi
CsoundObj.js was not written by me, and at the time of its creation I
had commented it would be nice to have it be similar to the CsoundObj
API on Android and iOS.  I think it largely has been.

CsoundObj as an API was not designed to be like csound.hpp, so it
doesn't really make sense to compare them.  CsoundObj was designed to
be platform-specific and idiomatic to the particular language/platform
it is on.  For example, some languages use objects while others may
expect function pointers or blocks. Some languages like Obj-C have
function and argument naming conventions that are different than
something like Java or JS.  CsoundObj was designed to be a
higher-level wrapping than csound.hpp or libcsound and originally
designed for Android/iOS.  Something like having method names with
upper-case would be expected on some platforms (C#) but not on others
(Java, C++, etc.).

CsoundObj implementations are expected to be slightly different per
platform but overall follow similar patterns of usage.  The idea being
a person writing a CsoundObj-based app for iOS would feel comfortable
porting their app to Android and to Web, but have their code be
written in a style that is idiomatic to the target platform.

I have no problems with CsoundObj changing and evolving, but I don't
think it makes sense to make it into something it wasn't designed to
be, which is the exact same on every platform. Also, for the original
platforms for CsoundObj (iOS and Android), it was always possible to
use the full Csound API for more complex tasks than what was in
CsoundObj. On Android this was via the C++ based Csound class, on iOS
via the Csound C API.

Finally, the issues about CsoundObj are taking into account issues
only related to different Javascript-based platforms and is influenced
by implementation details (like auto-wrapping methods when making them
available from WebViews).  I don't find the conventions being pushed
to be particularly idiomatic for Javascript (like function and method
names starting with capitals).

There's nothing preventing a separate API from being written that,
like CsoundObj.js, uses cwrap to get the C functions and then be
written to do what you want. (You could also subclass or wrap
AndroidCsound on Android and add your own methods with different names
and annotations, etc.). That'd solve your particular cross-JavaScript
problem without breaking CsoundObj's design and intent.

Re: [Csnd] Csound-wasm version at https://csound.github.io/wasm/

Michael Gogins-2
Thanks for your comments. 

Being idiomatic can be necessary at times, but in this case it was not necessary. 

So now we have a situation where a programmer or musician has one API for Android, iOS, and WASM, and another API for C++, Python, Java, Lua, etc. Rather than one pattern that works on all. 

I have no problem at all with the mere existence of CsoundObj or its implementation of an idiomatic pattern. But it should be an addition not a replacement. 

I suggest that you add the interface of Csound.hpp to CsoundObj.js, and also fix the sequencing difference I mentioned inn my earlier email. 

Then people new to Csound could use the idiom of the platform they know, and people who know Csound but are new to a platform can use the idiom of the synthesizer they know. 

In addition it would be much easier to move pieces especially those using HTML5 from platform to platform. This is really the main reason for standardizing the API.

Best, 
Mike

Re: [Csnd] Csound-wasm version at https://csound.github.io/wasm/

Michael Gogins-2
In reply to this post by Victor Lazzarini-2
What you suggest is similar to what I have done in csound_extended.js.

I used Emscripten's Embind wrapper generator. A single declaration wraps any signature that contains only numbers or std::strings as parameters. 

I subclassed Csound in csound.hpp as CsoundEmbind to create methods with std::string in place of char *.

Then I wrapped a CsoundEmbind object in a CsoundWebAudio JavaScript class which just uses the Web Audio and Web MIDI code from CsoundObj.js.

I do expose more of the Csound API this way and the semantics and sequencing are the same. 

The WASM Working Group is planning features that will make this easier. At some point pthreads and then dynamic loading will be possible. Then browser and DOM objects will appear in WASM, making it possible to code the Web Audio driver in C++.

Regards, 
Mike

I do not think the API will change in the case of CsoundObj, but if it does, it is Steven’s decision,
since he originated the design and wrote most of it.

It is possible, however, if anyone has the time and patience to do it, to write a JS version
of the Csound API that wraps the C or C++ functions more closely. I don’t know how
useful that would be, since all the interfacing with Web Audio etc will have to be done
outside it. But I guess it would give a lower level access to libcsound WASM.

Re: [Csnd] Csound-wasm version at https://csound.github.io/wasm/

Steven Yi
In reply to this post by Michael Gogins-2
I'll say it again: the CsoundObj API is designed to be idiomatic and
platform-specific, but share common design as much as possible to make
things easy to port between platforms.

Your comments about CsoundObj API don't make sense as it *IS* an
addition and not a replacment.  As I said, it is a higher-level API,
and access to the lower level ones was always available (C API on iOS,
C++ API on Android, cwrap on Web Csound).  Again, the whole point of
it is is to be platform-specific.

Does using upper-case named methods in Java make it look like anything
they'd see or learn when reading a "How to Program Android
Applications" book? Or any API documentation at all for Android? No.
The API for Csound for Android was designed with beginning Android
developers in mind, same as CsoundObj on iOS, etc. (It sticks out like
a sore thumb to me too whenever I use the C++ or wrapped API in Java
and Python on the desktop. And why not snake_case on Python?)  The
reason for that is the assumption not everyone who wants to make an
Android or iOS or Web app is going to be a seasoned programmer (maybe
just a musician with a dream) and making things idiomatic and in line
with documentation and conventions found for that platform/language
should make it easier for those users.

If you're an experienced Csound APi users on a different platform and
want to use the C++ API on Android, you can via the AndroidCsound
class, which is provided in the CsoundForAndroid SDK.  CsoundObj
itself uses it.  If you want to use the C API on iOS from Obj-C or
Swift, great, it's there. If you want to make a csound.hpp compatible
API for WebCsound, great, use cwrap and create one, no one is stopping
you.

In all of these cases, CsoundObj is an addition and adds tailoring to
the target language/platform.

Anyways, I know what you want, which is to write one JS app and run it
on multiple platforms. That isn't the goal of CsoundObj and CsoundObj
being around does not prevent you from achieving your goal. (And could
a CsoundObj implementation be made for each JS platform that was
identical to each other and still in-line with the other CsoundObj
implementations? Yes.)

The sequencing difference seems like a bug that should be fixed, but
otherwise these criticisms don't make much sense to me.

Re: [Csnd] Csound-wasm version at https://csound.github.io/wasm/

In reply to this post by Victor Lazzarini-2
One of the first opcodes and associated example files from the Csound Manual that I tried to implement and run is the flooper2 example program shown below, in the same form as in my text editor, except that I am trying to play a little jam session of mine that I recorded called "ringmod.wav" and I am trying to use flooper2 and the csound command line to play it back in different times and ways/w/different parameters. When I run the following csound command in the Terminal:
csound -Q0 -+rtaudio=coreaudio -odac -iadc flooper21.csd

& the flooper21.csd file that I try to run is in this form:

<CsoundSynthesizer>

ksmps = 32

But I get the following output & error:

I don't know where this "fox.wav" file is coming from since I replaced it with my jam session file "ringmod.wav", but it seems to be struggling to open my GEN01 function table.
Do you know of any ways that I can fix this program (or maybe command line) to play my "ringmod.wav" file? Any help would be greatly appreciated.

This is what I did in csound_extended.js. I think this is the right approach. 

This does not appear to be the case with csound.js.

Great!

I think something like that would be very welcome from users point of view! If
it has no contradictions with security or else, I guess for Csound use in web
pages that would be really useful.

I saw it has a new API method csound.startRealtime(config*).
It is probably necessary to distinguish from csound.start() but I find it very
important -  if ever possible -  that all html/javascript associataed APIs
would use same or similar methods -  so the same code works in Android, Csound
For Node, Wasm, CsoundQt etc.  What do you think?

Re: [Csnd] Csound-wasm version at https://csound.github.io/wasm/

joachim-3
yes it says it has this line in your csd:
   f  1     0.00     0.00     1.00  "fox.wav" ...

can you double check you really don't have in the csd you call?
