Cannot Play 44100Hz, 16-bit, Stereo wav files ni a VOIP based program.

Hi,
I have a VOIP program that makes the user at one end who calls the running java program to listen to the .wav file once the program picks up the incoming call from a sipphone. I have used SIP libraries in this project.
CASE 1:
When I provide a .wav file whose AudioFormat=PCM, Audio Sample Rate = 8000Hz, Audio Sample Size = 8-bit, Channel = 1(Mono), BitRate=128Kbps it plays well and i can hear the audio over the internet at the other end. In the code at one place I provide the following formats to the AudioFormat() function as mentioned below:
format = new AudioFormat(8000, 8, 2, true, true);where -
1st param = float sampleRate - the number of samples per second
2nd param = int sampleSizeInBits - the number of bits in each sample
3rd param = int channels - the number of channels (1 for mono, 2 for stereo, and so on)
4th param = boolean signed. - indicates whether the data is signed or unsigned
5th param = boolean biEndian - indicates whether the data for a single
sample is stored in big-endian byte order (false means little-endian)
Then I pass this format variable to transmit the audio format just formed. "format" is of the following type:-
//set of import statements in the file.
import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.TargetDataLine;
import javax.sound.sampled.Mixer.Info;
private AudioFormat format;

  • UCCX single play prompt step for multiple wav files

    Hi there!
    Is possible to use single 'Play Prompt' step to play a chain of .wav files on UCCX?
    For example, have variable chain_audio that can contain different content length
    ex:
    chain_audio = "P[1.wav] P[2.wav] P[3.wav]"
    chain_audio = "P[1.wav] P[2.wav] P[3.wav] P[4.wav] P[5.wav]" etc.
    Play Promtp (-Triggering Contact-, chain_audio)
    Is it supported?
    Thanks

    I'm not sure it is possible to call and fill Create Container within Java code. It is possible to setup variables by hand in Create Container Prompt step, like in Play Prompt step.
    Parse a String to Array and fill up Create Container Prompt with Array elements manually. In my example i have only 4 elements, but in real world i could have more than 15 elements.
    I wish Play Prompt/Create Container was filled automatically with chain of audio files, because it is impossible to know the array size beforehand.

  • How to play a wave file through the DAQ board?

    Hi there,
    we want to play a wave file that is saved on the harddrive via the DAQ board. Means we want to connect a amp to the analog output of the DAQ to amplify the sound and play it through a speaker.
    We couldn't find any VI that does that. Can anybody tell us how to play a wave file, or perhaps even send us a VI that can do that?
    Thanks a lot for your help
    Martin - Physical Optics Corporation

    Hi Martin,
    The only example that I could find on how to do this was using our
    older Traditional DAQ drivers version 6.9.3.  If you're using Traditional
    DAQ drivers, the vi can be found here. 
    The example reads a 8-bit mono .wav file (an example .wav file is included in the .zip file) and writes it to the analog out of your DAQ card.  I've updated the
    example to work with our newer DAQmx drivers and attached it here.  
    I hope this helps,

    The new 5.1 rentals supposedly have 2 audio tracks - stereo for devices that can't handle 5.1 via HDMI and presmably to give stereo audio out via the RCA sockets, and the 5.1 passthrough.
    It may be that with time more fucntionality will be added to movie playback, but I'm not holding my breath.

  • Importing wav files with dead space?

    I'm curious if anyone else has experienced slow loading times/overview calculations when importing wav files with lots of dead space into Logic?
    Working on vocal comps from a Pro Tools session. Logic has no problem importing full takes (24-bit, 44kHz wav files that basically start at the beginning of the song). But alternate takes that might have complete silence until the 3rd chorus, for example, take forever to load. 10+ minutes in some cases.
    If anyone can shed some light on this or share a similar experience, I'd appreciate it.
    Tech details, if it helps:  Macbook Pro 2.53 GHz Intel Core Duo, 4GB RAM, Lion 10.7.2, Logic Pro 9.1.6

    Well, iTunes has no ability to undo edits, so the problem may lie elsewhere. Please try the following extra-extra-careful procedure:
    - Edit the file and save it.
    - Exit the editor.
    - Make sure you know filename/location of the edited file, and that you are not confusing it with some unedited copy of the same song.

  • How to send wav file to NI audio out

    How do I send a wav file to the D/A Audio Out
    of a 6071E.
    A futher requirement is to send it out differentially
    using channel 0 and 1
    - Make Software User Friendly -

    I've attached an example to this posting. This example generates an analog output waveform on the board and channel specified. The waveform generated will be based on the WAV file selected. It is an example of the using a multifunction data acquisition board to play a WAV file on speakers.
    Instructions:
    1. Select the desired device and channel #.
    2. Enter the path to your 8 bit mono WAV file. ( a sample WAV file is included in attachment below)
    3. Enter the update rate for your Analog Output(AO) channel. This should equal the rate of your WAV file.
    4. Wire your speakers to the Analog Output channel
    5. Run it.
    6. The program will continue to loop the WAV file waveform on the AO channel until you clickthe stop button.
    How it works:
    An 8 bit mono WA
    V file is read from disk. After the data and header of the WAV file are extracted, the data is scaled from 0 to 1 V and then the entire waveform is written to the Analog Output channel specified. The example is set form continuous generation (or playback) and will continue looping the WAV files waveform until the stop button is pressed.
    I hope this helps.

  • P2 Audio render & replace yields mono .wav file

    I import some P2 footage (shot with an HVX200) and use the source channel mappings
    to map audio channels 1 and 2 to stereo and disable channels 3 and 4.  My sequence
    uses the DVCPROHD P2 720p preset with the frame rate set to 29.92 fps.  I
    then place a clip into the sequence.  Because of the source channel mapping a
    new stereo audio track is automatically created (Audio 5) and the audio from the
    clip goes into Audio 5, not Audio 1 through 4 (because they are mono).
    All is good so far and I can edit and export to my hearts content.
    However, I recently wanted to use Soundbooth to make some adjustments to the
    audio.  When I right click and select Edit in Soundbooth, Render and Replace I
    end up with a mono clip in Soundbooth.  Also the rendered clip that Premiere
    adds to the project has only a left channel.  However, the sequence itself
    seems to still have a stereo clip as evidenced by viewing the clip in the
    source monitor.  I cannot figure out how to get Premiere to render a stereo .wav
    file with both left and right source channels and pump it out to Soundbooth.

    Welcome to the forum.
    Since this is PrPro CS4.1, it should have been posted to the Premiere Pro sub-forum, as this one is for Premiere, prior to Pro. This is a new change in the forum structure, and all of us are still working through it.
    Now, let's see if we can get you to editing.
    Does the Audio Track, AT 5, have the stereo speaker icons, or just a single speaker icon? From your description, it should be the stereo speaker icon. You can also go into Audio Mixer and check out the signal, or Dbl-click on the Audio Clip to view it in the Source Monitor.
    Since Edit in SB is not doing what you and I think it should do, I'd bypass that, and just do an Export>Audio Only through AME (Adobe Media Encoder), as a PCM/WAV file. Open that in SB and edit, as is required. Do a Save_As (keeping your original Export file for safety) and then Import that edited Audio file into PrPro. Place it as is required on the proper type of Audio Track. Go to Audio Mixer and just Mute the old Audio Track. That should handle it fine.
    If you do have a mono file, you can create a dual-mono (not exactly the same as a stereo file, but similar), with Fill-Left, or Fill-Right. Still, from your description, you should have a stereo file and why SB is not seeing it as such is puzzling. Still, if you can get to editing, you can probably sort that part out, when you have time.
    Good luck,

  • Recognizing Markers in .WAV files

    ok so I have a .WAV file where I have placed markers (
    literally named Marker 1, 2, etc ) at different locations in the
    file. I imported my .WAV into director 10. I have next buttons
    where I want them, onDown to skip to the next marker in the .WAV.
    What code do I use to do this?

    You could start by grabbing the cuePointTimes list from the
    WAVE file,
    executing a findPosNear based on the currentTime of the sound
    playing,
    and set the currentTime to the next one found.
    Something like the following might get you started (watch for
    unintended
    line breaks):
    on mouseUp me
    -- assume the sound file is playing in channel 1 (alter the
    channelIndex to suit):
    tSound = sound(1)
    -- check whether the channel is currently playing a sound
    if tSound.isBusy() then
    -- get the currently playing #sound member into a local
    variable
    for faster re-use later
    tMember = tSound.member
    -- ditto its list of cue point (marker) times
    cpTimes = tMember.cuePointTimes
    -- how many cue points are defined
    nTimesListed = count(cpTimes)
    -- if there are *any*
    if nTimesListed then
    -- what's the current time of the sound playing
    curTime = tSound.currentTime
    -- what's the next listed cue point
    tPos = cpTimes.findPosNear(curTime) + 1
    -- if there is such an index in the cue point list...
    if tPos <= nTimesListed then
    -- ... then get its time
    tTime = cpTimes[tPos]
    -- and start the sound playing from here
    tSound.play([#member: tMember, #startTime: tTime])
    end if
    end if
    end if
    end

  • IPhone email WAV file attachment

    Hello. My company uses a system for voicemail, that will send an email to me with an attached WAV file with the voicemail in it.
    When I check the email and then select the WAV file attachment to play, it pops up with an error that says "this movie could not be played".
    I have researched this and noticed that the WAV file that is sent as an attachment is ecoded with "ACM Waveform". The only WAV file encoding that I found works on the iPhone is "PCM Windows".
    Is there any way to be able to listen to the ACM WAV file? Anyone know of a fix?
    WAV files encoded with ACM, ADPCM and PCM all play fine in iTunes. WAV files encoded with DVI do not however. Yet only the PCM encoded file will play on the iPhone.
    Any suggestions?

    Sure you can. I can send myself emails with WAV files and they open fine using the media player on the iPhone, provided they are encoded with Windows PCM. Anything else does not work.
    That is my issue. The WAV files that my system sends me are encoded with ACM. I need them to be PCM.

  • 5.1 WAV files

    Hi all!
    I´ve to edit a videoclip and sync it to a stereo wav file and a 5.1 wav file(s) - 1st time i do it, ans 1st time i do it in FCP.
    I don´t know if i´ll have multi files (total of 8 - stereo and 5.1) or if it´s possible to have a single wav that contains all stuff and then use 5.1 audio setting in FCP.
    With the sync video and audio (and some post, of course!) i have to export a wav file and a quicktime move to the final mastering session... so my questions: (at last :))
    - how should i ask PTools guy to send me the wav files (?) individual (?) is there a 5.1 specific file that i should use with fcp?
    - how can i export a .wav with the correct TC (?) it´s a simple export (?) or multi-export - 8 tracks?
    - to export a correct quicktime reference, matching the digibeta timecode should i use a visual TC (using a plugin) or if i export a normal quicktime it will have the project timecode?
    Thank you all!
    Regards

    5.1 surround sound requires Dolby or DTS encoding. You create a 5.1 from multiple audio tracks (be they .aiff, .wav, etc. Always use highest quality audio sources before encoding. Hope this is useful.

  • How to bounce or render a mono wav file?

    Hello all....this seems like a basic question, but I'm stumped. How do you bounce a stereo project to a mono (sum of both L and R) file? I switched the little "interlocking circles" symbol on the master output to a single circle, but that seems to move the summed audio to the L channel only, and then looking at the bounced file, it creates a stereo L + R channel, with the audio showing up on the L and a blank R channel. What I want is a single waveform containing both L + R audio, resulting in a balanced sound in L and R speakers. This should also result in half the file size of a stereo wav file the same length.
    Thanks in advance.

    Set the Stereo Outst to mono, then use the little bounce button underneath the fader to bounce. Using a bounce keycommand will always result in a stereo bounce. Using that little button will create a true mono file. If you have already inserted stereo Plugs on the Master Out this will not work, the Outs will remain stereo. So remove those plugs first.
