Can't record sound using the jack in/out on macbook pro 13 os x

hi
i bought a new macbook pro 13' intel core i5 4gb with the latest os x version 10.8.2. mainly for sound and video editing
yesterday i tried to record sound using garage band and through the mini jack port. once i connected an mp3 player to the mini jack port, the sound prefrences window recognized it as headphones and not as input jack as it did on my friend's same mac with leopard os on it.
it seems like no matter what i try to do (changing instument set up on garage band, restarting the computer with the jack in or out etc...) nothing worked
i bought this mac just so i wouldn't have to deal with these kind of problems....suppose to be a very user friendly os and hardwear.
very dissapointing. please if any one has a clue what can be done?

i'm aware of my other audio interface options, but i would expact this machine to have the basic options every 20 year old pc has, a simple plug and play difault to get audio into my computer. i bought it at b and h in NY and in their specs it says that it's a 'combo kack' - meaning both in and out analog audio ports. after cheaking mac's site it says only headphones.
also tryied to connect a digidesign mini mbox2, through the usb port, and i had to unplug it, shut down the mbp, restart it again etc.. and it also doesn't always work propely and makes all kinds of digital error sounds.
although in this case i can't that the mbox is not damaged.
over all it's very dissapointing. it's my first mac and i figured it would be a much more idiot proof, user freindly work tool.
if you got any other tips i'd appreciate that
thanx alot for the focusrite link

Can you record sound using a USB 6211 and convert the data to a .wav (or other sound) file?

Hello,
I am trying to build a system that will use a USB 6211 to record sounds from multiple electret microphones and then save the data as a .wav file or other sound file. I have already built my mics and hooked the mics up to the USB 6211; the DAQ device seems to do an adequate job recording the signal - I've recorded from 3 mics at a time at 11,025 Hz, although I don't know how good the signals are since I can't save them for playback after the fact, and they aren't going through my sound card. Ultimately, I would like to save the data as a multichannel audio file which I could then open in a program such as Audacity for further editing and analysis. Since Audacity can import a variety of sound files, my file format doesn't need to be .wav if another format would work better.
Any advice would be appreciated.
Thanks, Eric

If you are sampling all three simultaneously, your highest frequency recordable will be (11,025/2)/3, so about 1800Hz and that will pretty coarse (traditionally digital sound recording is at 44Ks/s at the low end). As to converting to a .wav, there are functions on the "Graphics and Sound" palette for saving waveforms to a .wav file.

How to record sound with Java Sound?

I just want to record a clip of sound and save it to a WAV file. I exhausted the web but didn't find a tutorial. Would someone be kind enough to give me a tutorial or a sample code? The simpler the better. Thanks.

Here's the code I used to record and play sound. Hope the length do not confound you.
import javax.sound.sampled.*;
import java.io.*;
// The audio format you want to record/play
AudioFormat.Encoding encoding = AudioFormat.Encoding.PCM_SIGNED;
int sampleRate = 44100;
byte sampleSizeInBits = 16;
int channels = 2;
int frameSize = 4;
int frameRate = 44100;
boolean bigEndian = false;
int bytesPerSecond = frameSize * frameRate;
AudioFormat format = new AudioFormat(encoding, sampleRate, sampleSizeInBits, channels, frameSize, frameRate, bigEndian);
//TO RECORD:
//Get the line for recording
try {
targetLine = AudioSystem.getTargetDataLine(format);
catch (LineUnavailableException e) {
showMessage("Unable to get a recording line");
// The formula might be a bit hard :)
float timeQuantum = 0.1F;
int bufferQuantum = frameSize * (int)(frameRate * timeQuantum);
float maxTime = 10F;
int maxQuantums = (int)(maxTime / timeQuantum);
int bufferCapacity = bufferQuantum * maxQuantums;
byte[] buffer = new byte[bufferCapacity]; // the array to hold the recorded sound
int bufferLength = 0;
//The following has to repeated every time you record a new piece of sound
targetLine.open(format);
targetLine.start();
AudioInputStream in = new AudioInputStream(targetLine);
bufferLength = 0;
for (int i = 0; i < maxQuantums; i++) { //record up to bufferQuantum * maxQuantums bytes
int len = in.read(buffer, bufferQuantum * i, bufferQuantum);
if (len < bufferQuantum) break; // the recording may be interrupted
bufferLength += len;
targetLine.stop();
targetLine.close();
//Save the recorded sound into a file
AudioInputStream stream = AudioSystem.getAudioInputStream(new ByteArrayInputStream(buffer, 0, bufferLength));
AudioFileFormat.Type fileType = AudioFileFormat.Type.WAVE;
File file = new File(...); // your file name
AudioSystem.write(stream, fileType, file);
//TO PLAY:
//Get the line for playing
try {
sourceLine = AudioSystem.getSourceDataLine(format);
catch (LineUnavailableException e) {
showMessage("Unable to get a playback line");
//The following has to repeated every time you play a new piece of sound
sourceLine.open(format);
sourceLine.start();
int quantums = bufferLength / bufferQuantum;
for (int i = 0; i < quantums; i++) {
sourceLine.write(buffer, bufferQuantum * i, bufferQuantum);
sourceLine.drain(); //Drain the line to make sure all the sound you feed it is played
sourceLine.stop();
sourceLine.close();
//Or, if you want to play a file:
File audioFile = new File(...);//
AudioInputStream in = AudioSystem.getAudioInputStream(audioFile);
sourceDataLine.open(format);
sourceDataLine.start();
while(true) {
if(in.read(buffer,0,bufferQuantum) == -1) break; // read a bit of sound from the file
sourceDataLine.write(buffer,0,buffer.length); // and play it
sourceDataLine.drain();
sourceDataLine.stop();
sourceDataLine.close();You may also do this to record sound directly into a file:
targetLine.open(format);
targetLine.start();
AudioInputStream in = new AudioInputStream(targetLine);
AudioFileFormat.Type fileType = AudioFileFormat.Type.WAVE;
File file = new File(...); // your file name
new Thread() {public void run() {AudioSystem.write(stream, fileType, file);}}.start(); //Run this in a separate thread
//When you want to stop recording, run the following: (usually triggered by a button or sth)
targetLine.stop();
targetLine.close();Edited by: Maigo on Jun 26, 2008 7:44 AM

How to record sound with JMF?

How to detect sound using JMF

Hi,
I want to detect a beep sound that is played on the machine by another application. Basically, connect to the sound card and see if beep was played. This sound would effectively play on the machine speakers. if speakers are present.
I want to eventually grab a couple of sounds but first start with beep. So, over a duration of 2 minutes, I would alternate between 'beep' and 'bang'. And whenever these sounds are played, I want to be able to detect them.
I would appreciate if there is sample code that I can start with.
I am new to java audio/media and most data that I found was recording sound from microphone.
Thanks.

I tried getting the device list on my system but the following code is not returning any devices (deviicelist is empty) ? When I look at my Device Manager on Windows7 machine, I see there is 'High Definition audio device' . Does anyone have a clue why/when would this happen ?
I have jmf installed and it is in the classpath. I also have jmf.jar, sound.jar added to my project.
CaptureDCaptureDeviceInfo di = null;
Vector deviceList = CaptureDeviceManager.getDeviceList(
                    null);
          if (deviceList.isEmpty())
               System.out.println("No Devices found");
          if ( deviceList.size() > 0 )
          di = (CaptureDeviceInfo)deviceList.firstElement();
          System.out.println("di::" + di.getName());

How to record sound into array using DAQ ?

Hi to everyone
Im last year student , im using LABVIEW for the first time.
i have an myDAQ , i need to record audio go through the analog ports/AUDIO INPUT of the myDAQ, into array, for later singal proccesing.
its for my final project.

First, Learn to use LabVIEW with myDAQ is a series of videos. To quote the Introduction,
The Learn to LabVIEW with MyDAQ provides fundamental LabVIEW knowledge for a great out of the box experience with your MyDAQ. Each unit provides a set of videos to allow you to learn at your own pace and review material an unlimited number of times. As well, most videos are accompanied by minor exercises which will help drive home important topics and challenge you along the way.
View the videos, do the exercises, and I suspect many of your questions will be answered. If you write some LabVIEW code and have a problem, come back, show us your code, and explain the problem.

Can I record sound using a microphone and then upload it to server?

Hello guys I thank you in advance for reading this. What I want to know is if it is possible to record a sound clip using a microphone and then upload it to the server using a swf applet in a webpage. Im an experienced java/javascript programmer but just starting out with flash/action script. What technologies will I need to do this? Can I do this simply using simply an swf file and an apache/php or jsp page? Again, thanks alot for your help.
-BeWilled

You can Microphone class in Flash to record the sound and it will directly upload to FMS server .
Use the Microphone class to capture audio from a microphone attached to a computer . Use the Microphone class to monitor the audio locally. Use the NetConnection and NetStream classes to transmit the audio to Flash Media Server. Flash Media Server can send the audio to other servers and broadcast it to other clients running Swf files .

How to record audio using wireless phone headset on a mac (Adobe CS6)?

I have purchased a Plantronics Savvi w440 headset, with which I want to record audio. I was assured by the company that I could.
Well, Audition won't record me talking; it only "picks up" about 1 sec, then stops recording.
I have used a variety of mics before; I know how to set them up in Audio Hardware. My Default input & output are this new headset. Still, no recording.
I have Audition CS6 on a macbook pro.
I need help. Thanks.

Thanks Bob for your help. I had already downloaded and installed the software for this headset on my Mac. Still won't work. There are no updates for this headset. At least, I haven't found one.

How to record sound only

please anybody help me for giving a useful forum or some text or some example source code

Its simple dear,
just find the Audio i/p device using CaptureDeviceManager and defining audio format you wish to record
Vector<CaptureDeviceInfo> devices =new Vector<CaptureDeviceInfo>();
devices=CaptureDeviceManager.getDeviceList(new AudioFormat("LINEAR",44100, 16, 2));
then you got device
make datasource using this device location (using getLocator())
then set Datasource realize processor and tranmission is started then

How to attach sound using link to any button?

Hi,
am using this code to call sound file after click on button.
PAdha1.onRelease = function () {
mySoundC = new Sound(this);
          mySoundC.attachSound("PAdhaSound1");
         mySoundC.start(0, 99); //10 represents the number of loops
         gotoAndPlay("play2");
                      _global.myTaalLaya = "High1";
My problem is I have more than 100 buttons and their own sound files.Now ,this buttons are on separet scene so, it creates separet image for each button and separet sound for each button which is in liblary.Now,my problem is there are huge sound files and button images.So,flash is not supporting this.It does not show .swf file(Output result).
I think this is beacause of a lot of images and sound files.
Is there any other way to call sound file through link function.Now sounds files are called through "linkage".from liblary.
am using flash cs 5 with as 2.

I found some refrance it,works.But another thing is every code i found is applied on button.But,I cant use this code b.coz I have n number of buttons,it will again create problem.Can u suggest me anything more?
I want something like it will attch sound through folder path (link).And 1 button should abale to play more than 10 sounds with diffrent click.
