Audio streaming with a microphone

Hi,
I want to realize audio streaming on the net using Java Sound API :
- I get a computer, server on witch I connected a microphone, and I want to capture sound and transmit it in real time on the network to any browser that request to play sound from my server.
- I want to use JMF API and I need also a code sample that solve my problem and I will adapt it to my project when mastering JMF
Thank you.

Hii Frends ..
Here is lick http://www.dickbaldwin.com/tocadv.htm. Go to the bottom of webpage and u will find a list of articles with live code for caputring and playing sound. hope ti would help

  • HP Wireless Audio streamer with Windows 8.1 (64 bit) on pc

    I am running windows 8.1 (64 bit) on my laptop and recently purchased the HP Wireless Audio streamer. I was unable to install the software off the disc  as it is not compatible with Windows 8.1.  Any solutions? Please keep it simple as I am a rather lowtech person. Thanks.

  • Does my new XBR65X900C support 5.1 audio streaming with Netflix?

    Hello, Does the XBR65X900C support 5.1 audio streaming via the optical output or ARC via Netflix or Amazon in 4K? I've tried connections to my receiver via ARC and also via optical, and the TV: - In Netflix never shows "5.1" as an option- Only outputs two channel in Amazon On the receiver I've tried two of the three audio options:- "Auto 1" setting, which outputs compressed audio with no changes- "PCM" setting I didn't select "Auto 2" at first which seems to be the same, but sends compressed, multi-channel audio with no changes but I'm assuming it would have no effect given the wording implies it simply sends two channel audio compressed without encoding. I did subsequently try the "Auto 2" setting, but it had no impact on the issue. I did try the same receiver (Onkyo TX-NR1030) with an LG TV and it receives a 5.1 source from the same Amazon account. The manual suggests the TV does in fact support streaming audio in 5.1, but I cannot seem to activate this on the TV. Please advise,Matt

    I have just bought the KD55X8500C on Saturday, only to find that the TV doesn't have 5.1 for Netflix.  I am yet to try google play movies, but from what I am seeing, I'm not holding my breath. It's 2015 SONY!! How can a $3k TV be sold that can't do 5.1 sound on streaming services, and no where on your site or in merchandising material to you highlight that this is a limitation of the TV. I want a Sony rep to tell IF this going to be fixed, WHEN it is going to fixed, or if not, where do I get approval to return my TV for a full refund so I can go buy a SAMSUNG that I know can do this. Again wont hold my breath - in Australia the tech support phone line is only available from 8am to 6pm on weekdays!! So only unemployed people can get support!

  • Audio capture with mono microphone

    I have an old JVC GR-DVM5 and I just bought an audio-technica ATR35s lapel microphone. It is a mono microphone. I would like to use this setup to record simple interviews.
    I can set the Log and Capture Device control to 'non-controllable device' and get a recording of both audio and video, but the audio is very 'left' dominant - even if I connect (toggle) the stero/mono seettings in the 'clip settings' pane.
    Is there a better way to do this, given the equipment I have? I would like the audio levels to be equal (balanced) between both left and right channels.
    thanks!

    How do I get it to just capture to a single channel?
    You can't. FCP likes to work in channel pairs and likes to assume stereo (in a world in which I believe extremely little acquisition is done in usable stereo).
    You deal with which audio goes where after capture.
    Just capture it as mono and either:
    - delete the unwanted audio clip after moving to the timeline, which is exceedingly annoying, or
    - turn the unwanted source audio down in the bins, which is kind of annoying, or
    - use your track targets and channel patches to allow a place for only the wanted audio when you put it on timeline, which is still annoying but a lot less so.
    Then either:
    - Pan each and every audio clip to center on the timeline, which would be mind-numbing, or
    - Push the "Downmix" button in the Audio Mixer window, which is easy but then makes it very difficult to designate any stereo in your sequence (e.g. music and effects).
    I hope my frustration with FCP's handling of mono audio doesn't show.
    Better yet for you I would say: record the same mic to both channels, with one being at a safer lower level than the other. This way you have a backup channel if things get out of control loud.

  • Audio streaming with iWeb without advancing a page?

    I set up my website with five menu buttons on the Welcome page which are linked to five different mp3 audio files. I published the public_html folder to a non .mac host. If you go to my website and click on an audio menu button on the Welcome page the site changes to a different page with a QT audio feed and you can hear the audio streaming. All well and good.
    But I don't want my site to change to another page to hear that audio. Because when the visitors want to hear the next audio sample they have to click their backpage button and go back to the welcome page to start the process again. Each time they want to hear the next piece of audio they have to backpage return to the Welcome page.
    Instead, while still staying on the Welcome page, I want the ability to stream the audio when a button is clicked, without being taken to another page. I want the visitor to be able to hear the audio without leaving the Welcome page.
    Is there a way to do this?
    Thanks, Panther

    I'm sorry. I don't understand your instruction: target="myself"
    When I'm using iWeb and I want to link the menu button to something my choices are:
    One of my pages (which is a page within my iweb pages)
    An External page (which is a URL off my site)
    A File (which, in my case, is the audio mp3)
    An email message (which directs the link to start up an email message with a predetermined email address)
    So, what exactly is: target=myself?
    Thank you for your reply

  • 4 video and 2 audio streams with AWS

    Good time 4all!  I've try to solve next task.
    There are 4 IP-cameras in my local network, for example 192.168.1.40-192.168.1.44. So, task is to make broadcast streaming video from all of this cameras and sound from couple of those. The main question is next: HOW_TO_DO_THIS? )))   How redirect streams from local IP-s to FMS in Amazon Web Service, for getting four unique URL-s for each camera?

    I would use a combination of client side and server side scripts. you could kinda do this like dns assign each ip address to a stream namd and then direct FMS to use that name as a stream name. or you cold just make sure you sanatize the ip address to a string datatype and use the resulting string as the FMS stream id.

  • Recording audio voice with single microphone but getting stereo output

    I am trying to record a voice recording to a video using a Scarlett microphone.  I can only record in Mono.  How do I get the voice out of both speakers when playing back and/or record on both sides using one microphone?

    After you add the sound to your timeline search the help file for the "fill left" or "fill right" command

  • AS3 Audio Stream

    I'm trying to find a way to capture an audio stream from the
    microphone instead of having to send it to FMS. Anyone have any
    idea how this can be done? I don't care what format the audio gets
    stored in as long as I can play it back. I might store it in memory
    and I might save it to the hard drive using AIR. Some folks have
    figured out how to do this for video with the AS3 PNG encoder so
    I'm sure there's a way to do it.
    Could this be done by hacking the NetStream class somehow?
    To any Adobe folks listening in, Flash could really use video
    and audio encoding classes! I argh every day that it doesn't.
    Thanks.

  • USB audio problems with 2013 iMac

    I'm having a strange audio problem with USB microphones and headsets. The issue with my Logitech H650e is shown in this screencast I recorded. In the first part of the screencast, I am not speaking into the mic—yet you can see the levels fluctuating as if there is static playing (not in a natural pattern that you'd see when someone is speaking). In the next part of the video I demonstrate that selecting the built-in iMac mic for input, and then re-selecting the Logitech headset temporarily solves the problem. You can see the input start to fluctuate normally as it should when I am speaking. But at 0:31 in the screencast, you can see the input levels freeze and stop registering anything. I continued to speak until the end of the screencast, but no input was detected. For this screencast, I was on a Go To Webinar call, but the problem occurs regardless of whether I'm using Skype, Go To Webinar, GarageBand or any other software.
    The problem with my Blue Yeti USB microphone is also different. In that case, the input does not freeze as it does with the Logitech headset. The levels appear as you would expect, and it seems to work. However, the person on the other end can hear static in the background, even though I don't hear it in my own headphones. I learned this because I just tried to do a Skype interview with the Blue Yeti, and the interviewer told me they could hear static. We closed Skype and called each other back twice, but the problem persisted. Then, suspecting the problem was related to what I described above with the Logitech, I unplugged the Yeti and then plugged it into my Macbook Air 2013 (also running Mavericks). Lo and behold the static completely disappeared.
    My Griffin iMic and Audio Technica lavalier mic (attached to the iMic) behaves similarly to the Yeti, except in this case I can hear the static when I speak with my monitoring headphones. The input works but I get a lot of cracking and static in the background. This was confirmed by calling the Skype Test Call number and recording a message, which is then played back.
    Here are the facts:
    All 3 of my USB audio microphones/headsets do not work with my 2013 iMac running Mavericks
    All 3 of these microphones/headsets worked fine with my 2008 Mac Pro running Mountain Lion
    All 3 of these microphones/headsets work fine with my 2013 Macbook Air running Mavericks
    In this other thread, several people are reporting similar issues with the iMac 2013 and Mavericks. At least two people did not have the issue when the iMac 2013 was running Mountain Lion. This of course suggests the issue is the combination of the iMac 2013 and Mavericks.

  • Transmitting audio stream by RTP

    Hello:
    I am trying to transmit audio stream with this code, but i dont get it work well.
    The output is:

    Track 0 is set to transmit as:

    Created RTP session: 1.1.9.147 45200
    Start transmission for 60 seconds...
    Code to AVTransmit2.java:
    * Use the RTPManager API to create sessions for each media track of the processor.
    private String createTransmitter() {
         // Cheated. Should have checked the type.
         PushBufferDataSource pbds = (PushBufferDataSource)dataOutput;

    // The local session address will be created on the
    // same port as the the target port. This is necessary
    // if you use AVTransmit2 in conjunction with JMStudio.
    // JMStudio assumes - in a unicast session - that the
    // transmitter transmits from the same port it is receiving
    // on and sends RTCP Receiver Reports back to this port of
    // the transmitting host.
              port = portBase + 2*i;
              ipAddr = InetAddress.getByName(ipAddress);
              localAddr = new SessionAddress();
    //*          InetAddress.getLocalHost(),

              rtpMgrs.initialize( localAddr);
              rtpMgrs[i].addTarget( destAddr);
              System.err.println( "Created RTP session: " + ipAddress + " " + port);

              sendStream.start();
         } catch (Exception e) {
              return e.getMessage();
         return null;
    The code receptor is working well, because I tried it with JMStudio.
    Why it doesnt transmit ?
    I need your greatly help.
    Thanks.

    What is different from your previous question ?

  • Recording 2 audio streams separately with iChat?

    Is there a possibilty to record the iChat video chat with the 2 audio streams in separate files? (so one for the video, one for the microphone and one for the speaker)

    Hi,
    No, the Audio is Full Duplex meaning that both ends can speak at once and be heard by the other.
    The iChat Recording option records the Audio as Mono and combined from both ends.  (At least in versions prior to Lion - I have one Lion/iChat recording and it is listed as being in Stereo but again the Audio is from both ends).
    SoundFlower may possibly be able to grab either the Local Audio (mic Input) or the Output (which is Buddy).
    I have never used it and don't know if it can record two things at once.  (It seems to stop at the Leopard version)
    Audio Highjack Pro (there is no NON Pro version any more) might provide another answer (but it will cost)

    Hi Brian,
    Thanks restoring and restarting didn't fix my problem - i have started it fresh and still it doesn't work. Basically I press ONCE on the remote, after the machine has not had any commands for 10 minutes, and the cursor skips from one end of the menu to the other - so I can't choose network or update software etc - I sometimes manage to stop it randomly in the middle of the menu if I press on a command in the middle of the cursor skipping all the menu steps...not sure what the problem is but I have basically not used my brand new apple tv since I bought it for that reason! I should call Apple support I suppose! grrrr hate wasting time with stuff like this!
    Thanks for your help though!

  • I want to be able to use airplay to stream audio to another iOS device, and then use that audio stream to be used when recording video instead of the built in microphone / microphone input. Is this possible?

    I want to be able to use airplay to stream audio to another iOS device, and then use that audio stream to be used when recording video instead of the built in microphone / microphone input. Is this possible?

    A third-party app probably cannot obtain a stream from another app. To the best of my knowledge, such a capability is not provided in the software development kit, apps being "sandboxed" from each other and so allowed to communicate only in very specific and limited ways.
    I'm not completely sure what you mean by "limitations on video capture". An iPhone, to the best of my knowledge, can natively record video only through it's built-in camera, and audio while doing video recording only through the built-in microphone or mic/headphone jack. There might be a video recording app that would allow audio input from an external device connected to the dock connector, but I'm not sure.
    Regards.

  • No audio streaming movies with iTunes 10.2.1 and iOS 4.3

    I upgrade to iTunes 10.2.1 and to iOS 4.3 and now I can´t listen audio on my movies with 6 channels audio. With two channels (stereo) there is no problem. With multichannel I just can see the video, but can´t listen. The problem is with my iPad and my Apple TV. On my iMac it works fine, I can see and listen.
    Anybody Help ??

    I have the similar problem with video. I can not stream movies to apple tv after ios 4.3 update that i used to stream before. The problem seems to be for some (but a lot) specific movies though. After going through all my videos i found a couple of videos that was able yo be streamed. Even with movies that can't be streamed the video loads (and even plays on fast forward but very slow without audio) but just pauses. It just loads opens and everything but just doesn't play.I don't have any problem with streaming audio from ipod or etc. I can still stream video from youtube as well but just can't do it from my itunes.
    Just to be specific, i have the issue with my ipad as well. The movies that i can stream to atv can be streamed to ipad as well (from my pc windows) but for other movies neither my atv nor ipad can play. A clear **** up by the developers. Just can't understand how they can release without even checking possible flaws.
