I need to get audio input from users having just browsers (and not only IE). Is there any good way to get audio stream with a brouser to server.
If it possible to avoid Java, flash etc?
Thanks.
You could do it with flash.
Have a look at http://livedocs.adobe.com/flash/9.0/main/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Parts&file=00000297.html
P.S.: Html alone can't do it. You would need a plugin.
No. You need a plugin of some sort. HTML itself doesn't support microphone input.
-- EDIT
As answered a few secs before me, you can use many third party plugins, such as flash and java. But you cannot avoid not using them.

Im learning to code web stuff. ruby,javascript...
I would like to do something that makes noise like www.audiotool.com
The app is basically a DAW, digital audio workstation, is fast and sounds good... you can eveb use samples and save projects in the cloud.
But my main question is which languages or tools can make an app like this ?
but i don't know which languages make this kind of apps posible ?
is it creating the sound in the browser, or in a server and sending it back ?
any guesses?
Audiotool.com uses flash to synthesize audio. Their FAQ says that you should update your flash player if you're having trouble, so that seems like a pretty strong indication that they use flash.
However, if you want to make music apps, I would advise against using flash. Newer devices and operating systems will drop support for flash (iPhones/iPads already don't support flash, I believe).
If you want a future-proofed music-making solution, you can do that all client-side in javascript with the web-audio api.
I have authored, and actively maintain a javascript library that aims to simplify the process of building complex apps with the web audio api. If you're just getting started with making music on the web, you might want to check it out. The web audio api is not terribly beginner-friendly, in my opinion. https://github.com/rserota/wad
I'm working on a C++ application which takes microphone input, processes it, and plays back some audio. The processing will incorporate a database located on a server. For ease of creating UI and for maximum portability, I'm thinking it would be nice to have the front end be done in HTML. Essentially, I want to record audio in a browser, send that audio to the server for processing, and then receive audio from the server which will then be played back inside the browser.
Obviously, it would be nice if HTML5 supported microphone input, but it does not. So, I will need to create a plugin of some kind in order to make this happen. NPAPI scares me because of the security issues involved, so I was looking into PPAPI and Native Client. Native Client does not yet support microphone input, and I believe that the PPAPI audio input API would be limited to a dev build of Chrome. FireBreath doesn't look like it supports any microphone function either. So, I believe my options are:
Write my own NPAPI plugin to record the audio
Use Flash to get microphone input
Bail on browsers altogether and just make a native application
The target audience for this is young children and people who aren't computer-adept. I'd like to make it as portable and simple to use as possible. Any suggestions?
If you can do it all in Flash and have the relevant knowledge, that would probably be the best solution:
You can avoid writing platform-specific code, delivery/updating is easy and Flash has broad coverage so users don't need to install any custom plugins.
FireBreath doesn't look like it supports any microphone function either.
You can write your own (platform-dependent) code for audio recording with FireBreath, just like you could in a plain NPAPI plugin. FireBreath just makes it easier for you to write the plugin, the result is still a NPAPI (and ActiveX) plugin with access to native APIs etc.
You can use Capturing Audio & Video features in HTML5, see this link for more information.
I'm just wondering how, and which audio player I should use to allow my visitors to play audio files on my website.
Thanks!
I use a flash-based player cleverly called "MP3 Player". Nice looking and easy to use (and free!)
Flash is the most widely available platform capable of playing sounds in a web page. It is highly likely that flash is already installed in their browser.

I want to build a Firefox extension that will allow me to directly manipulate the audio output, applying live filters and effects, from (for example) a streaming video site. Im struggling to find any good resources to help me. I think the effects bit will be ok but I need to find a way of intercepting the audio stream output. Does anyone know if this is possible?
Thanks,
Tom
Sorry, it's not possible. I don't know of any web browsers that expose an interface that lets you manipulate audio output.
Keep in mind that a lot of audio output comes from plug-ins like Flash, and those plug-ins are sending the audio output directly to your operating system - they're not even routing it through your web browser. So it wouldn't be possible for your web browser to intercept the sound if it wanted to.
I have a large amount of audio stored on my web server in a very custom format that can't be replayed by anything other than my own application. That application is a Win32 app that can connect to my web server and stream and replay that audio.
I'd really like to be able to do the streaming and replaying from within a browser, but don't know where to start. Ideally I'd like the technology to be cross-platform (unlike my current Win32 app) and cross-browser (IE 6 and above and Firefox).
My current thoughts are to look at things like:
Flash, but doesn't that only replay mp3 audio?
Java, are VMs freely available still?
Converting the audio to a WAV file on the web server and then using someone else's plugin to replay that file. I'd rather keep the conversion off the web server for performance reasons, but is still an option.
Writing my own custom plugin to do the complete stream and replay operation.
Any guidance would be most useful.
Please note that the audio is not music and that simply converting to another audio format is not trivial. The audio that is stored also changes frequently (every minute) would need constant conversion.
Why are you using a proprietary music format? I'd probably not even bother downloading a program to listen to it.
I would suggest you convert it to mp3 and then use flash.
Building your own plugin would probably be hard, there are so many different platforms you'd have to cater for, something like flash is written for them already.
Apart from converting server-side: Implement a decoder for your format in ActionScript or Java. Then you can write a Flash movie or Java applet that plays it. Both languages/runtimes should be fast enough to decode in realtime unless your format is very complex. Flash would be the more accessible of the two, since nearly everyone has the plugin installed. (It's possible that playing a raw sound buffer isn't supported by older Flash versions than 10, I'm no expert on that.) The Java plugin is definitely free, but you'd require the users to install it.
I'd go with converting the audio to WAV (or MP3) on the server. Writing your own cross-platform browser component would be a lot of work, thanks to the different ways the major OSes handle their audio APIs.
Try taking a look at shoutcast.
Basically its a server app that will stream music to any client that connects to it through a browser (effectively your own radio station). I've never used it myself but should be straight forward.
Another idea is winamp remote. Again you install the app on the server but this time you can browse your music collection on their website and play individual songs.
