Converting recorded WAV files in Advanced

Hi
When I record my vinyl onto my laptop I record them as WAV files. When I want to convert them I simply go to 'Advanced' & convert them to MP3's...Very easy.
How ever, when I use my brothers laptop to do exactly the same process it only gives the option to convert them to AAC versions! They take much much longer & it simply does not give me the option the covert to MP3!
We both have exactly the same operating system (10.4.11) & iTunes (8.0.2)
Any ideas?

When you convert a song in iTunes it will be converted to the format that you have set to import your CDs in. If you are using iTunes 8 go to Edit>Preferences>General and click on Import Settings, change your option to MP3. Go back to your library and highlight the songs you want to convert and go to the Advanced menu at the top of your iTunes window and choose "Create MP3 version:

Sorry you are having problems. Can you give an example preferably of some small publicly available file and the site you are trying to download it from ?
As a simple example of a download (ok it is a .png image file not not a .exe file) but can you try to download a copy of your avtar/icon, as used on these forums. In Windows one method is that you right click & should get an option save. <br/> Mine alongside uses the link
* https://support.mozilla.com/media/uploads/avatars/avatar-257447.png
Are you able to download such an image, then see it in your download manager, and find it on your computer.
Once you have got Firefox to save your binary file you can use it. In the case of the .exe file you are trying to download that should be usable as intended with your Windows Operating System, the avatar also should be easily opened and viewed.
P.S.
You could try installing the add-on https://addons.mozilla.org/en-US/firefox/addon/opendownload-10902/ if you wished to adapt Firefox to run .exe files instead of just save them.

Converting a WAV file to a Raw Audio File

Is there an easy way to convert a WAV file to a raw audio file? Maybe some way to just strip the file header?
Would if work if I just loaded a WAV file into an AudioInputStream and read all the bytes out and dumped them directly back onto disk via a DataOutputStream? Even if so, there must be a quicker solution, right?
Thanks!

And I'm not entirely sure what you mean by a "quicker solution". That's literally about 10 lines of code...
JavaSound wasn't really meant to do audio processing, it was designed to give you access to sound data so you can do audio processing if you want it. It's not particularly useful, but it is extremly powerful...

Recording wav file

HI is there any way to record wav file using Code composer studio to TI 5510 DSK and play them back. I am having problem writing a code to record in wav format. Plz help if there is any simple code to understand. Thank you

akki20,
I think you are looking for Texas Instruments. That is, unless you are somehow interfacing the 5510 DSK with LabVIEW or are using Measurement Studio for display / control. Let us know if that is the case.

Can i convert a wav file to a digital signal without using DAQ?

i tried the coversion of a sine wave to digital signal, ofcourse it doesnt work on converting wav file to a digital signal. i am also new in labview. i tried to explore it but there are many functions that i can't use.
so my these are my questions.
1) is a .wav file is an analog signal?
2) can i convert it without using any DAQ device?
tnx guys! i'll post the programs that uses quantization of a simple sine wave. i tried it to .wav file but it didnt work.

.WAV is a digital "signal". It uses Pulse Code Modulation to encode analog signal. You don't need a DAQ device to "convert" it to analog. Any computer with a sound card, and media player can "convert" a .wav file to the analog audio signal it represents

How can I convert a wave file to a jpeg file (picture) is it possible???

Hello:
How can I convert a wave file to a jpeg file (picture) is it possible???

zuckini;
I am pretty sure you know, but just to be completely sure: a wave is (usually) sound signal and a jpeg file is an image.
If you mean how to display the wave signal in a graph and then save the graph as a jpeg file, then just drop a graph indicator in the control panel, wire the signal. Check any of the example shipped with LabVIEW on how to do this. To get the image, drop a graph indicator's invoke node in the block and select "Get Image". Check this page for detailed information.
If you have something else in mind, please reply to this message with additional information about the wave signal, the image, etc.

Cisco AQM 8.5 not recording : wav files are deleted from client side

Daer Networkers,
We do have Cisco AQM 8.5 SR2 ES1 installed with UCCX 8.5
The issue is that when accessing the Web interface of AQM and try to look for calls, I can't find any one.
When checking the client side, I can see that the call are being recorded : The FROM and TO files are there. But once the call is terminated, the wav file appear for some seconds and then it dissappears asi fi it's deleted.
The wav files are not in the server too;
I don't know what is the issue. Can you please help ?
Thanks in advance.

Hi,
This issue was resolved by doing a repair to the QM Base services, then run postinstall as if it was run for the first once.
The Proxy Gateway program was missing for some reason. After doing the repair the issue was resovled and calls are uploaded to the server.
Now I am facing another issue ! : I can hear the client voice only. Agent's voice couln't be heard in the recorded files. As if the agent's voice is not recorded. Can you please advise ?

How do I convert a wave file of 50-60 meg into an MP3 to send to a client?

This is ridiculous...I'm reading the help page and it's been absolutely no help whatsoever.

From the iTunes help page searching for "Convert".
" Saving a copy of a song in a new file format
You can convert a song to a different file format (and keep a copy of the original). For example, you can save a copy of a compressed song file such as MP3 or AAC in an uncompressed song format (AIFF or WAV).
When converting from a compressed to uncompressed file format (for example, from MP3 to AIFF), you shouldn't notice any reduction in sound quality. However, when converting between compressed formats (for example, MP3 and AAC), you may notice a reduction in the sound quality. For the best results, if you want your music encoded in a different file format, import the music again from the original source using the new encoding format.
IMPORTANT: Except for iTunes Plus songs, you can't convert iTunes Store purchases.
To convert a song's file format:
Choose iTunes > Preferences, click Advanced, and then click Importing.
In the Import Using pop-up menu, choose the format you want to convert songs to, and then click OK to save the settings.
Select one or more songs in your library (Command-click to choose multiple songs), and then choose Advanced > "Convert Selection to...."
To convert all the songs in a folder or on a disk, hold down the Option key and choose Advanced > "Convert Selection to," and then choose the folder or disk containing the songs you want to convert.
The song in its original format and the newly converted song appear in your library."

Recording audio files in PCM_FLOAT format

Hello!
I'm trying to record voice sample and I've got a problem with my .wav format. With:
AudioFormat format = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED, 44100.0F, 16, 1, 2, 44100.0F, false);everything works fine. But what I need (because of further analysis of this audio file in Matlab) is PCM_FLOAT format:
AudioFormat format = new AudioFormat(AudioFormat.Encoding.PCM_FLOAT, 8000.0F, 32, 1, 4, 8000.0F, true);which unfortunately returns an error:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException:
No line matching interface TargetDataLine supporting format PCM_FLOAT 8000.0 Hz, 32 bit, mono, 4 bytes/frame, is supported.I've tried a lot of different combinations with PCM_FLOAT but every one of them returns same exception. I'm probably missing something but the question is: what? How can I find what audio formats could work with my sound card? If I can only use PCM_SIGNED or UNSIGNED how can I convert recorded .wav file to PCMFLOAT?

I've finally been able to try what you suggested. As server received from the client an array of bytes I tried to convert it to an array of floats:
IntBuffer sbuf = ByteBuffer.wrap(myAudioBytes).order(ByteOrder.LITTLE_ENDIAN).asIntBuffer();
int[] audioInts = new int[sbuf.capacity()];
sbuf.get(audioInts);
float[][] audioFloats = new float[audioInts.length][1];
for (int k = 0; k < audioInts.length; k++)
    audioFloats[k][0] = ((float)audioInts[k])/0x8000; // Two dimensions in audioFloats because Utils.floatsToWav needs to know whether it's mono or not.
}and then save it to file using http://code.google.com/p/j-simple-wav-io/ :
Utils.floatsToWAV(audioFloats,new File("output.wav"),8000);Unfortunately it didn't work. I checked the .wav files with AudioFileInfo from jsresources.org and it recognizes the format of output.wav as:
Type: WAVE
AudioFormat: PCM_SIGNED, 8000.0 Hz, 16 bit, mono, 2 bits/frame, little-endian
Lenght of audio data: 22050 frames, 44100 bytes, 2,75625 seconds
Total lenght of file (including headers): 44144 byteswhile valid audio file (I mean the one that actually works with my Matlab script) is:
Type: WAVE
AudioFormat: PCM_FLOAT, 8000.0 Hz, 32 bit, mono, 4 bits/frame
Lenght of audio data: unknown
Total lenght of file (including headers): unknownBefore that I tried to do it another way:
- getTargetEncodings(originalFormat) --> returned PCM_FLOAT (amongst others);
- isConversionSupported(targetFormat, originalFormat) --> returned true;
(where originalFormat is "PCM_SIGNED, 8000.0F, 16, 1, 2, 8000.0F, false" and targetFormat is "PCM_FLOAT, 8000.0F, 32, 1, 4, 8000.0F, false" - as you can see above I don't really know if Matlab wants little or big endian).
so I thought sth like this will do the trick:
ByteArrayInputStream bais = new ByteArrayInputStream(myAudioBytes);
AudioInputStream AIS = new AudioInputStream(bais, originalFormat, myAudioBytes.length / originalFormat.getFrameSize());
if(AudioSystem.isConversionSupported(targetFormat, originalFormat))
    AIS = AudioSystem.getAudioInputStream(targetFormat, AIS);
File file = new File(fileName);
int nWrittenBytes = 0;
try
    nWrittenBytes = AudioSystem.write(AIS, AudioFileFormat.Type.WAVE, file);
}It didn't work either (but it seems that this bit can help switching from 16 to 32 bits and from 2 to 4 bits/frame).
So - clearly I've done something wrong but again have no idea what. I'm sort of new to Java and an absolute novice to processing audio files so thanks for all the advices :-).

Problem in playing back mp3 which was recorded as wav file

Hi all,
I have recorded sound using my program. It uses classes like AudioSystem. And it's
able to record and play also. but in my site I have an mp3 player. So i thought of converting the recorded wav file into mp3. For this i used LAME utility in Linux. And it was converted. Also it is being played in normal players like Winamp. But when i try to play this converted mp3 file using my player in my site it's having problem. Why is it like that?
Should i do something while capturing the sound from microphone so that it can be converted into mp3 format??
Or
Can I directly capture voice to an mp3 file??
In my program,
targetDataLine.open(audioFormat) where audioFormat is like
float sampleRate = 8000.0F;
int sampleSizeInBits = 16;
int channels = 1;
boolean signed = true;
boolean bigEndian = false;
Should I do something more or change something??
Please help me...
Thanx and Regards,
sand...

Thanks Walter.
Unfortunately, the same issue happens... In whichever window I select "Bounce" from -- Environment, Audio Mixer, or even FILE > BOUNCE -- a window titled "Bounce 'Output 1-2' " pops up. I'm guessing this is what you mean by the "Bounce Output Window." But, there I'm only able to name the file in the "Save As" field, choose where to bounce the file to on my harddrive, and then click on "Bounce" in the bottom-right of the window. I have no tabs or anything else to choose from. So I'm still a little stumped. Any additional thoughts?
I really appreciate the help.

Converting WAV files to MP3 files

I have a USB turntable for converting my vinyl records to digital. When the files are imported to itunes they are large WAV files. I there a way to set up itunes to automatically convert the WAV files to MP3 files?

Old thread, but still very useful. I too looked for a converter for Mac
for ages and stumbled across your forum. Now you can use an app called audio converter for mac, It costs a bit, but u can try it out free first to see if it works for what ,you need it for. Plz click the link below to get more info: http://www.mp3converter-mac.com/wav-to-mp3-converter-for-mac/

Converting .wav files to mp3 format.

Format[] FORMATS = new Format[] { new AudioFormat(
AudioFormat.LINEAR) };
String srcFilePath = "C:" + File.separator + "Users"
+ File.separator + "vkiran" + File.separator + "Desktop"
+ File.separator + "test" + File.separator + "4a714ea2.wav";
String mp3FilePath = "C:" + File.separator + "Users"
+ File.separator + "vkiran" + File.separator + "Desktop"
+ File.separator + "test" + File.separator + "4a714ea2.mp3";
File srcFile = new File(srcFilePath);
File destFile = new File(mp3FilePath);
MediaLocator source = new MediaLocator(srcFile.toURL());
DataSource d = Manager.createDataSource(source);
ContentDescriptor cd = new ContentDescriptor(
FileTypeDescriptor.MPEG_AUDIO);
Processor p = Manager.createRealizedProcessor(new ProcessorModel(d,

p.configure();
System.out.println((p.getDuration()).getSeconds());
MediaLocator destination = new MediaLocator(destFile.toURL());
DataSource ds = p.getDataOutput();
DataSink sink = Manager.createDataSink(p.getDataOutput(),

sink.open();
sink.start();
sink.stop();
sink.close();
p.stop();
p.close();

You are converting the WAV files to mp3 format before transferring them to the iPod?
You're using iTunes to do this?
Just for the record, the iPod will not play mp3 files below a bit rate of 32kbps nor will it play compressed WAV files.

Converting WAV files to MP3

When trying to convert my wav files to mp3 in itunes, I get an error pop-up that says "The disk could not be read from or written to." These files worked fine before I updated to the new itunes.

PaulSimpson wrote:
The files are on my hard drive Steve. They were audio files that I downloaded from my personal camera. I didn't even think these kinds of files had permissions.
OK just wanted to make sure. Sometimes, read/write errors occur when write protection is enabled on, say, an SD card. (that little tab on the top)
All files actually have permissions under Mac OS X, one of the aspects of the underlying UNIX file system. Every file is capable of being readable, writable, and/or executable by either the owner, the group to which he/she belongs to, and/or everybody. Sometimes accessing files becomes erratic when the file's permissions unknowingly change, thus the good idea to "repair permissions" from time to time with Disk Utility.
However, you mentioned that the original WAV files came from your digital camera. What happens if you try to open these WAVs with the QuickTime Player? Do they play as per usual?
PaulSimpson wrote:
If you still think repairing my permissions with my install disc is the way to go, I'm game, but I'm going to need a bit more step by step.
We'll save that for a little later. Originally, I was leaning toward the feeling that the hard disk may have needed verifying/repairing (through Disk Utility) - because of the read/write errors. But it is possible that it may be an issue with the WAV files themselves.

How do I convert soundbooth .wav to .cda files?

I have tried to convert soundbooths .wav file to .cda file format using Nero software, but it says I am missing a required plugin to do this.
Does anyone know what plugin this may be?
I am using soundbooth 1.0 and Nero 8.
Does soundbooth add something to there .wav format?

.wav must be 44.1K sample rate 16 bit stereo in order to burn to CD.
