Audio recording problem

Hi all

Can anyone suggest me the code to run the audio recording!

The implementation of audio recording!

Hello

Check this code it will work.


try{
            player = Manager.createPlayer("capture://audio?encoding=amr");
            player.realize();

            rc = (RecordControl)player.getControl("RecordControl");
            bt = new ByteArrayOutputStream();
            rc.setRecordStream(bt);
            fc = (FileConnection)Connector.open("file:///store/home/user/RecordedFiles/audio1.amr");
            if(!fc.exists()){
                fc.create();
            }
           ot = fc.openDataOutputStream();
            rc.setRecordStream(ot);
            rc.startRecord();
            player.start();   

            }catch(Exception e){
                e.printStackTrace();

On the audio recording problems

Hi all

I have a problem with regard to save audio files in Labview.

In my program, I acquire the audio signals of the soundcard of the PC constantly and save them in a queue. After that certain prerequisites are activated, these audio signals in the queue is stored in a .wav file. This program works well, except a problem, which is the time lag in this .wav file. For example, I save a sound segment for about 30 seconds, but after the backup, this .wav file is just 21 long s. It contains all of the original recorded segment, but the time axis is compressed, which sounds like played fast. I searched all day and could not find any information about it.

These sounds record and save functions are part of a comprehensive program, and I'm sorry that I can't give a single vi on it. I add the numbers below and I hope it helps. I am also willing to provide any additional information.

PS: I have reviewed the incompatibility caused by approximation of the "t0" (published in http://forums.ni.com/t5/LabVIEW/Time-mismatch-with-Sound-Input-Read-VI/td-p/1385404 ) and compensate for that during the savings phase. (see figure 2)

Thank you very much for the help!

Hi, Vans,

Thank you for your response.

For your questions.

1. I'm using Labview 2011 sp1 on Windows 7/Xp. I tested the program on desktop computers and laptops. I don't know about the types of sound card, but given that this problem occurs on several different computers, I think that this is not the problem of sound cards.

2. for the sound card sampling frequency, in fact I checked that. I read signals of waveform of the 'read.vi of sound entry' and the term 'dt' is equal to 1 on the sampling frequency. So I think that the sampling rate of the sound card is correct.

In fact I have just solved this problem by myself, but the solution is pretty weird. I think there are two reasons that caused this problem.

1. when I receive tones of "read.vi of sound input", I first save them in a queue. Once the acquisition is completed, I save all the signals in the queue to a .wav file. But I'm going to do to overcome the overlapping sound and the gap caused by the "t0" reconciliation, a waveform signal re - organize before saving it, as below. According to my knowledge, I think that this 'dt' in the resulting waveform (indicated by the arrow) must be the same as before, but in fact it is not, and it becomes 1.

2. Thus, to solve the first problem, I manually change the term "dt" once again as below. After the change, I'm sure that the "dt" is back to the correct value. But then is the strange thing is I saved the same signal waveform in two different ways, using "his write.vi file" and "file its writing simple.vi" respectively. The first method is the one I have used before and it caused the problem I posted here. The second works. In my program, I put as 16 kHz, 16 bits/sample, and 1-channel sampling rate. The file .wav from the first method has a strange flow 705 bps and the wave from the second method file has the right bitrate which is 256 bits/s.

I tested the program of hundreds of times and each time he acted like I described above. I don't know if anyone has ever faced the same problem as me, but I hope that my solution can be useful for others. And I also hope to be useful to improve your LabView products.

Thank you for your time.

Best regards

I am facing problem with playback of the audio recorded.

Original title: sound recording problem

Use built in mic, I recorded w/vocals/guitar,... and playback starts well, but after a few seconds the sound loses the basis... or low frequencies.

It is uniform everytime I try. What I am doing wrong?

Hello

What version of the Windows operating system is installed on your computer?

If I understand correctly you are facing some problem with the audio recorded. There is no way to lose the sound after a few seconds; There seems to be a problem with the registration. I suggest you to run the game audio recording Fixit then try to register once more and check if it works.

I tried to record some live audio. I downloaded Wondershare Streaming Audio Recorder I opened the program - but could not hear the audio I tried to play.

original title: sound problems

Hello!

I tried to record some live audio. I downloaded

Wondershare Streaming Audio Recorder

I opened the program - but could not hear the audio that I tried to play. I don't know if downloading this program is related to the problem.

I opened Skype - and everything worked fine. I could hear, etc. But if I run an MP3 in Windows Media Player - I hear nothing!

My sound is at the top.

In my Volume mixer, I see:

1 output device digital (SPDIF) bounce up and down. (but I don't)

2 but applications: sounds of Windows, Windows Media Player and Google Chrome will not move. (but they are at the top).

Any suggestions?

Jews

I managed to get the results of work. I don't know where come the SPDIF.

I downloaded a new driver Realtek for audio from the computer. This corrects the problem.

But I still want to know what happened.

Select the audio recording device

I have inspiron 1501 (a new replacement), with 32-bit amd anthlon, windows vista OS.

My micro phone volume was very low, the person on the voice chat could not hear it. I tried to make it work properly, by mistake, I disabled the device for registration of the properties. now I don't know how to re - activate again. It gives the message that no audio device is installed. I think by the upgrade of a link to forums to dell than the old problem will be over, but I do not know where to install the audio recording device. I tried the installation of equipment as well, but did not work.

Premiere Pro CS3-"audio recording is not possible?

I'm reinstalling Adobe Premiere Pro CS3 on a new computer, but getting the message across "his currently installed adapter driver does not support entry DirectSound.» Audio recording is not possible. I took note of comments on the problems of his fellow men elsewhere but have not seen anything which seems to solve this problem. Is the problem with the change in windows Vista environments to Windows 7 (on Dell Alienware i7) or I have to buy another sound card, or is it Premiere Pro CS3 here the rub? Thank you, eirrom.

Yes, quite probably a compatibility issue. CS3 used an older model of compatibility, which long has been surpassed by newer versions of DX. However, still does backward compatible, so the problems you might have may depend on requiriung a specific driver, installing the legacy DirectX or as a minor, full support by changing some permissions on the system to allow the loading of drivers unsigned legacy and compatibility modes. It's a problem more complex that simply flipping a switch eitrher average. Check your device manager and then work your way through...

Audio export problem

An audio clip on my time line is not exported with the rest of the video. It has synchronized audio to an audio recorder and this is the only clip that comes out of the silence. Other audio is rendered. The clip shows up on the time line and normally reads on the time line. Someone had this problem? Is there a solution?

I have "fixed" the issue by exporting to the hearing and recording an audio extract file. He seems to have recognized it. In a test report.

I got errors 'Master clip' whenever I opened the project and the same audio clip should not any audio in it. I have to copy the audio track to another project and paste in this timeline of projects and it worked for a while until her SOUL would not export the clip said. I tried to dissociate and restoring links the file without result.

I also have issues when I open the project none of the media seems to load, his perpetually showing 'media pending' to fix this I then re - enable and disable all clips that brings media partners in the time line.

At work, I have second dacking and monitor\ stations. Plug my laptop into a docking station.
Open captivate and slide deck, choose it Audio > Rrcord > zip
Opens the control of audio - I want to save. everything is fine.
Eject from the docking station, tried to use portable Captived on any computer (no dock, no attached monitor)
Select Audio > recording > zip
No recording control window, the window in captivity is there but all the disabled buttons. Press ESCAPE - caprivate window buttons to reactivate.
Togle window to see if there was a hidden window - not good
Resized screen - not good
Made sure to disconnect it from the projector (fn + f7) - not good
not rebooted - no good
not rebooted - no good
Tried the configs different montor - not good
Are gone home, I tried my monitor at home with an another docking station
does the same things as before - not good
Nothing.
Return to work - works fine.
I can't do all the rocrding at work that my office is too noisey.
Help?

Hello

I had similar problems after having cut a second monitor. Captivate seems to leave some dialog boxes on the second monitor which is no longer there. Before disconnecting (at College) of the second monitor I check if everything is once again on my main screen (laptop computer =) and then no problems. But now, I am confused, as if I forgot (which I did yesterday), I connect another second monitor, extend my desktop to this monitor and can't seem to drag everything back to the main screen. It seems to be a different configuration with your docking station.

Audio recording is no longer works in Cap5 - ideas?

I created a presentation and audio recording in several ways (Audio - recording - slide) (the Audio icon in the taskbar).
Yesterday, I opened the Captivate and these two options don't work anymore. I do not mean that I can't save. I mean I can't access the screen in the software that lets you record.
Registration generally works very well - I record in Audacity. This isn't a problem of Windows (XP) or an entry problem or a hardware problem.
Everything else works in Captivate.
Audio of the previously saved slide sets. I just can't save. After using the above option, Captivate freezes and I need to click ESC to unlock.
I know, it's weird. If you don't believe me, look here. Let me know if you see me something wrong while you're there.
http://screencast.com/t/0fsLsR5Lh
So, I did what anyone facing a weird isolated software problem would do. I reinstalled Captivate. Today, same problem.
Help? Any ideas? I do the final changes on my project, there is a delay, etc., etc.

First thing to try is empty the cache using the key in the preferences.

If this does not resolve the issue, you can try closing Captivate and delete the Preferences file itself.

On Xp, it is located at: C:\Documents andSettings\Application Data\Adobe\Captivate 5 Settings\

Captivate will re-create this folder next time it starts, but settings preference, you have done will be lost.

Additionally, make sure that you have installed all the updates and patches.
