Sound file write

Hi,
I am taking sound input from mic and writing it in a wav file (using example Sound Input to file).
but when i feed the signal from function (signal) generator greater than 1 V then the recorded wav file shows clipping in the example read sound file to chart.

Clipping will occur then you go outside the AD converter voltage range. So what did you hope to see from your test?
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

Is it right to use the "sound file write simple.vi"?

I had a problem to use the Sound File Write Simple.vi that is it can not save the data.
The links are shown in the following picture.
I wonder is it right for me to use that vi like that shown in the picture?
And why I can not save file as *.wav while I can save it as a *.txt?
Thank you!

No command lines do not work inside stored procedures.
Firstly, remember that the stored procedure is running on the database server so any files it can access have to be on the server itself.
ZIP is an operating system command, so you would have to have some java code or some other means of shelling out to the operating system to execute it, an area which I'm not to familiar with doing myself as I've never found a need to.

How do I transfer a sound file via TCP?

I have a .wav file that I'm trying transfer via TCP. Using LV 8.5, I modified the "Sound File to Output.vi" example to send the data across a TCP connection to a client vi. But, I've encountered numerous errors along the way with trying to convert the sound data which is a 1-D array of waveform double. I've attached my server and client VI, but essentially, what I tried to do is break down the array into the y and dt components, send those over the TCP connection, rebuild the waveform client-side, and then play the waveform. Is there something I'm missing? Do I need the timestamp information as well and send that over too? Please let me know how this can be accomplished. Thanks!

One thing to clarify: While the Sound Output Write does not need the dt information, the dt information wouold be required when you use the Configure VI in order to set up the rate. However, you only need to send that parameter once. Thus, it would seem to me that you want to change your client code so that it checks to see if it receives a special command or something to indicate the start of a new song that may have been sampled at a different rate. If this is the case, then you can reconfigure the sound output. Otherwise, all that you're listening for is just song data that you send along to the Sound Output Write.

How to input sound file into MS Access Database, not random folder?

Hi, I am trying to input a sound file into an MS Access 2000 database, I know it can be copied and pasted into there, but how can u input into the database with a user record, i also need the code to extract it as well as inputting it....at the moment it records the sound and stores it as test.wav on the local drive....

Hi
I Learned how to read a file text and Parse as StringTokenizer. But still i don't know how to read the Individual tokens into to database.
But now i face a new Problem, i am not able to sort it out.
i am posting my code
import java.io.FileReader;
import java.io.FileWriter;
import java.io.BufferedReader;
import java.io.PrintWriter;
import java.io.IOException;
import java.io.*;
import java.util.*;
public class CSVExample {
 public static void main(String[] args) throws IOException {
 BufferedReader inputStream = null;
 PrintWriter outputStream = null;
 try {
 inputStream = new BufferedReader(new FileReader("file.csv"));
 String text;
 while((text=inputStream.readLine())!= null)
 StringTokenizer st = new StringTokenizer(text);
 if(st.hasMoreTokens())
 System.out.println(st.nextToken());
 } finally {
 if (inputStream != null) {
 inputStream.close();
}Here the Problem is The file.csv has got two fields ID, NAME The content of this file is as follows
T12,MR.RAJ KUMAR
T13,MR.EARNEST DIES
T14,MR.MATHEW HYDEN
Now when i StringTokenize this File The Output printed as follows
T12,MR.RAJ
T13,MR.EARNEST
T14,MR.MATHEW
That means when it finds the Space it is not printing the Remaining Text.
Please Help me in this and then Tell me how to INSER The Tokens into the Database Table
Thank you for your service
Cheers

Need to play and stop sound file with 1 ms resolution

Hi,
I'm trying to open a .wav file then later play it at a time when another parallel loop activates a boolean local variable which controls playback in my "sound" loop. I need high time resolution in stopping the playing of the .wav file, ~1ms. From what I've gathered, I can't use the "sound output write.vi" because it locks the loop until it finishes outputting a set number of samples. Because of this, "sound output stop.vi" has to wait until the next iteration, which is more than ~1 ms.
In the help menu of the Sound Ouput VIs it says you can set the task ID for the "sound output start.vi" using the "sound output configure.vi." Unfortunately I've only been able to use the "sound output start.vi" following "play sound file.vi", and I don't really know why this is the case.
I can't start my sound with the "play sound file.vi" because it locks the loop its in until it finishes playing the sound. Oddly this only happens when there is a parallel loop running, if I run it by itself, with no other loops, it doesn't lock the loop. I thought it might have something to do with the local variable, but the loop doesn't lock when the loop restarts the sound using the "sound output start.vi."
After opening a .wav file, can i use the "sound output configure.vi" to create a task ID for the "sound output start.vi" to work? Or do I have to use the "sound output write.vi" after calling the "sound output configure.vi." The help menu makes it seem like the prior suggestion is possible.
Thanks a lot!

Since it sounds like the problem you're running into is getting the data loaded from the file before you're ready to play it, look at the Files sub-palette, specifically the Sound File Read Simple VI. You can use this VI to load the data into a waveform and have it ready for use later in the program.
So in your overall program, read the file with Sound File Read Simple and configure the output with Sound Output Configure and call Sound Output Write when you're ready to play the waveform.

Sound File not creating from simulate signal

I am trying to create a white noise sound file.
100 Hz to 8000 Hz 100ms long with a 10 ms ramp up and 10 ms ramp down.
I have been able to create the signal and sound in this vi.
Create sound - 8000 hz white noise
High pass filter - remove noise below 100 hz
ratio window - causes ramps
turn back into waveform - why oh why
normalize after filtering - for some reason the filtering changes the height of the whole waveform, if you have a solution to this......
play back sound
write sound to wav file.
The problem is, I can only get a file as short as 500 ms. I did this by changing the simulate signal options selecting 8000 samples at 16000 Hz.
If I select 1600 samples (the number of samples needed for 100 ms) some error occurs in the writing process, and the file thinks it's still open by labview. If I close labview, the file still does not work. How can I do what I need to do? Why can't I just reduce the number of samples to 1600 and get a 100 ms long waveform?

The Labview sound system is something that NI do not care much about. They actually neglect it. Errors reported in version 8.6 are still not fixed in Version 2010. And if they fix errors you can be sure some new errors will be introduced. What you can try to do is using the old sound system (used in 7.x) for writing your data to file. In your case it should have much to say. You will find the old sound system here ..\National Instruments\LabVIEW 20xx\vi.lib\sound\sound.llb
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

Sound File into AIFF file, 8 Bits, 8 Khz.

Write a small program that takes any sound file and converts it to: AIFF file, 8-bit, and 8-kHz, and a single channel.
Explain each step plese.

No, you should not lose any quality. File sizes are comparable, but .aiff supports a tag to which you can add artwork, .wav doesn't. If you want smaller files with no loss of quality convert to Apple Lossless. One of my test files is about 2/3 the size of the original.

Sound file and custom play.

Hello, I have an sound file and, want to play part's of this file not the whole sound file every time, in my application.
e.g i want to play from 1:23 min till 1:29 min can i do this in an iphone app and how?
Thanks in advance!

yes i know that way, but i want to have a big sound file and keep some pointers in an array with the seconds i want, depending some user actions, the whole sound file is usable, but in different user actions different parts of it will be played! Is there a way doing that? Without splitting the file into pieces?
A similar example could be found at youtube comments when someone writes a time point...example 3:25 of the video this refers to a link and when its pressed you auto transferred to the 3:25 'th second of the video....I tried to give you a related usage...I dont know if you understand what i mean...
thanks anyway!

Hi Experts,
I've a procedure where I'm using

On executing the proc, a blank file (size=0) is getting generated in the UNIX directory. But it also throws an error to the client where I'm executing the proc.
Error at line 1

Found a similar thread: Error with dbms_xslprocessor.clob2file
Any help is much appreciated.

Did you manually create that file_x.xml in the TEST_DIR directory, or has that been created by Oracle? If so, then Oracle has been able to write to the directory, so the issue may be around space on the disk?

Sound file storing in Database & accessing these files

Hi Friends
i have working on the project of Sound Recognization system
the requirement is that sound should be passed through mike input device & that sound should be stored in to database along with the user & password
for recognization & identification of user
But problem in storing the sound files in the database so how can i store the files into the database so please guide me.

brad103 wrote:
In my particular application, I process the byte array from the TargetDataLine. Then I save this to a db using new ByteArrayInputStream(soundData), soundData.length); where soundData is my byte[].
Am I correct that this will save the data in the relevant format (eg PCM_SIGNED, 8k, 16bit, etc), but the header information is not included? That's correct. Essentially, in JavaSound, that data has an associated "Format" object that was part of the line the data came from, would need to be given to any line the data was going to...and that format object is essentially a container for all of the header data...
And if so, then if I control the saving and retrieval then I can omit that step anyway as I know the format?You can omit the AudioSystem.write step and store the byte[] directly into the database...as long as you're capable of, as above, recreating the Format object that was originally associated with the data.
And my next question (digressing slightly, sorry umeshS), is that when using the tritonus gsm library and converting from above format to gsm, should I be using AudioSystem.write to write to an outputstream prior to calling AudioSystem.getAudioInputStream(targetEncoding, originalAIS) to convert encodings?AudioSystem.write adds the file header to the stream, and that's all. If you're using a "stream", you have to have the Format object in order to create an AudioInputStream, so there's no need to add the file header (and the file header will screw things up if you're not using the File or URL versions of getAudioInputStream)...
So, as a giant summary...
AudioSystem.write adds a file header, which will include format information. This should only be used if you're planning on using AudioSystem.getAudioInputStream(File f) to read the file the next time.
Otherwise, just save the data and the Format object associated with the data, so you can read it all back in later by building an AudioInputStream around your favorite IO stream.
And in retrospect, after explaining all of that...umeshS, the problem with the way you're doing it is that when you copy the file into the database, you're copying the file header. And then, because you're not using the "File" version of AudioSystem.getAudioInputStream, the system isn't handling the file header being there correctly.
You need to copy things into the database by creating an audioinputstream of your file, and then saving out the raw byte[] data. You can just call "read" on the ais a bunch of times and throw the results into your stream. Then, you can play it by pulling the data out of the database via a stream, and playing that stream by throwing it back into an AudioInputStream.

Source data lines don't play the file when you open them, you have to manually read data from the AudioInputStream and write it to the SourceDataLine...and you're not doing that.
You essentially walked into the bathroom, lifted the toilet seat and unzipped your pants...and wondered why the toilet wasn't making that "I'm peeing" sound. It's because you didn't start actually moving urine from your bladder to the toilet...

Problems with sound VIs - can't create usable new sound file

hello all!
I'm trying to create a VI that will, in real time, take a sound file and place it, on demand, as many times as you want into a longer sound file. it should place the file once each time a button is pressed. The rest of the audio I want to be just silence, but still filling time so that the output file is in real time.
(i am a sound editor for TV shows, and for my master's thesis i'm trying to create this program so that I could say, watch a video clip of someone walking and at the same time place footstep sounds in real time while watching the clip, just by pressing a button each time i see a footfall.)
i attached the VI i have so far. the only subVIs are in the Sound VI palette (no custom subVIs are used). No external hardware is used, so you should be able to see exactly what i see. i would attach the WAV file, but it's not an allowed attachment. You should be able to use any WAV, stereo 16-bit, 44.1 kHz file.
the problem i'm having so far:
the resulting WAV file is not playable by any means I can figure out. and it's always 4 KB. So obviously I'm missing something - maybe misuse of the Sound VIs? (Though the VI does recognize that I'm feeding it a stereo, 44.1kHz, 16-bit file. so that's good.)
i'm working on a Mac Powerbook G4, Labview 8.2, 1.5 GHz, Mac OS 10.4.8, 1 GB RAM. and i've tried both the
internal sound card and an external sound card (Digidesign's MBox which works with
ProTools).
thanks so much for your help!!

Is a printer connected? Is it turned ON? Is the driver up to date?
Illustrator checks this every time and also writes information on the printer into the file.

Make sound file from byte array?

Ok say I have a program that gets a byte array from a sound file and then randomly removes some of the samples from the array, so that instead of having a value the bytes are just zeroes. I then want to play my new byte array. Here is the code I try to use but when I use it nothing happens.
AudioFormat = ((AudioInputStream) AudioSystem.getAudioInputStream(**The Original Sound File**)).getFormat();
int numBytesRead = 0;
DataLine.Info dataLineInfo = new DataLine.Info(SourceDataLine.class, audioFormat);
SourceDataLine sourceDataLineTemp = (SourceDataLine)AudioSystem.getLine(dataLineInfo);
sourceDataLineTemp.write(audioArray, 0, audioArray.length);(Try..catch removed for clarity.)
Also, is it possible to convert a byte array to a .wav sound file?

Im pretty sure if you just write that byte array to disk and open it as a wav file that will do the trick, because thats all a wav file is anyways, a stream of bytes representing audio

Read sound file from disk in Java

Write a simple application that reads a sound file from disk (use a Clip). Play the sound backwards by arranging the byte arrays/frames in the reverse order.
Please I need an explanation of every step.

Hi,
When execute this code, I see this: "[Ljava.io.File;@111f71".
How I can see the name of the File, and How I can run a program with one by one from the files reader in a parameter ???
Thank's.
