How to process overly compressed high volume audio files

I used a process in scientific filters in audition 3 to process overly compressed high volume audio files normalized to 0 db. It was like magic.
How would you process this sort of file in Audition 6.

Below was the process used in Adobe Audition 3. The sound was much improved. Try the steps on a file you have to hear the difference.
Effects- Amplitude - Normalize - uncheck the decibles format box - normalize to and normalize L/R boxes checked, enter 48 into percentage box.
After normalization was complete
Effects - Filters - Scientific filters - select Chebychev 1 tab - band pass button and select the following parameters.
Cutoff =4, high cutoff = 22050, order = 18 all other settings at defaults values (0). Delay radio button sellected, check the extended range box, press OK.
Increase to appropriate volume after processing if necessary.

CCM 2.0 - Files Storage for high volume of files

Hi all,
I have seen in one message the following information:
<i>1. Files storage.
My point is that I think you've created a virtual folder on the SRM Server in SICF, which means that all your files are stored internally in the database, and not physically on the server.
The most simple way is to create a physical folder on the server OS, and then create analias in SICF to this folder. You then will be abble to load in mass the pictures on the server using FTP, or network Share.</i>
I want to upload images in the Catalog (CCM 2.0) and in my case I have high volume of files. Where is the best place to stored this data, in the database or in the server?
And if it is in the server, how I can create an alias?
Many thanks!!
Regards

Hi ,
What we had done for image upload for CCM 2.0 was like this:
1. in SE80 go to MIME repository -> drill down to services -> bc /sap/bsp - >Create a personal folder
2. Import your image .jpeg in this folder.
3. Derive an URL with the structue : server name/domain name/services/file name
4. test this URL in IE browser ,it should open the picture in IE for you.
5. then paste this URL in the characteristic 'image' of an item in master catalog in CAT
with this in EBP we could see the photos of the items.

HT201066 How can I split a long recording audio file into multiple audio files?

Hi,
How can I split a long recording audio file into multiple audio files?
With Windows I was using Nero software, which is not available for Mac. Is there any similar app for free for Mac?
Thanks!

Hello ingiorgio
You can import the track into GarageBand and then split the tracks there. Once that it is done you can highlight the ruler section and then share the song to iTunes to get them separated out.

How to Convert iTunes Songs (Apple lossless audio file) to a MP3 for E-mail

How to Convert iTunes Songs (Apple lossless audio file) to a MP3 for E-mail?
My computer is Windows 7 and my Itunes software version is 1.0.2
Many thanks in advance...

iTunes 1.0.2 is +at least+ eight years old.
The current version is 9.2, and it's free.
If that was a typo, and you're using something more current:
In the iTunes preferences, change the import settings to mp3.
Then select the songs you wish to convert.
From the "Advanced" menu, choose "Create mp3 version".
When done, change the import settings back to Apple Lossless.
That's it.
BTW, this is the Logic Pro forum, which has absolutely nothing to do with iTunes.

How do I play a video and audio file at the same time on Apple Tv?

I need to play a video loop (with no audio) on my apple tv and also play some music in the background. Its a video loop with no audio and then I need music to play in the background. The loop needs to repeat all day because its only 5 min long and the audio is an entire play list that's several hours. This is for a lobby flat screen setup.

QuickTimeKirk wrote:
Very difficult request because the Apple TV can only play one file at a time. It doesn't have a "loop" feature.
You could use QuickTime Player Pro to "join" the audio files into one file. The hard part would be adding the five minute video chunks via copy/paste as each would be added as a new "video" track. QuickTime .mov files can have up to 99 "tracks" and the .mov container is supported by Apple TV.
So this new file would have a new video track (actually just a copy of the original) that played up to 98 times. A five minute source video would end up being a bit over 8 hours in duration.
The 98 track video could be "flattened" into one video track via export. The same for the audio track movie.
Other options:
Set the Quicktime Loop flag in the movie inspector properties.
Make a video playlist, adding the file to the playlist lots of times - make sure playlists are enabled in Settings for video not just music.

How to get the length of a audio file without play it ?

Now I know a method to get the length of a audio file by play it:
1 Create a Player, and add a ControllerListener
2.Start the Player
3.In the ControllerListener's controllerUpdate method, use getMediaTime() by receiving a EndOfMediaEvent
However I think this method is not convenience, if I don't want to play it how I can get the length of the audio file?
Is anyone can help me?Really thanks a lot !

I got the answer here:
http://forum.java.sun.com/thread.jspa?threadID=5149132&tstart=15
I tried getDuration() before, but it always return a same time, I think maybe I didn't realize the player.

How can determine the duration of an audio file

Hi,
i'm making speech recognition project using java. i can capture sound by michrophone and playback it. the type of the sound is .wav.
my question is how to determine the recording duration (for example: determine the duration for 0.25 second) because i must recorded syllable,the assumtion is needed less than 0.5 second to say a word. and then.. can this wav file be changed into... binary or integer ?
thanks for your help

FYI I'm newbie in Java,
Yes, I want to limit the audio file lengths to a certain value. What should I do?
I have read wav file using an AudioInputStream, for audio format I'm using sampleRate = 8000.0F and sampleSizeInBits = 8. My friend said if I used 8 bit for sampleSizeInBit (resolution in amplitude) the binary file should be -128 till 127 in range according to the bit. I try this code and the result is binary file which is zero, positive, and negative.
the code
try{
audioInputStream.read(audioBytes);
for (int i=0; i<audioBytes.length;i++){
System.out.println(audioBytes);
catch(IOException ioe){
System.out.println("Error"+ioe);
I'm not sure that the code is right, but it works. Should I change the audioBytes into integer before? I try this code but it doesn't work.
int a = new int[audioBytes.length];
for (int i=0;i<audioBytes.length;i++){
a[i] = new Byte(audioBytes[i]).intValue();
this binary file has been printed in console (Im using texpad). So, how I can write that to file.txt? I'm using FileoutputStream but it doesn't work correctly. Here is the code
FileOutputStream fos = new FileOutputStream(strFilePath);
{audioInputStream.read(audioBytes);
fos.write(audioBytes);
catch (IOException ioe){
System.out.println("Error"+ioe);
When I open file .txt is read as character like this üüüüüüüüüüüüûüüüûüûûû ||||||| ||||||| ||||||||||||||||||||||||||||| ےےےےےےےےےےےے (like using alt plus number)

How can I get a low resolution audio file?

Hello to all. I have recently upgraded my iTunes to 11.0.03. I remember being able to create a new audio file of specifications offered by the menu in iTunes. My present requirement is to make a low quality MP3 file of an existing higher quality file and find that I am unable to do it with this new version of iTunes which only creates a new version of like quality and does not offer me options of selecting the quality of the file I need to make. Any help in this matter will be deeply appreciated.

Thanks Jim for the leads. I did go into preferences>import settings and set it to the lowest offered quality. When I then selected the file and clicked, I have not been given the option of converting the file but only create:
When I had earlier clicked this option, it only resulted in a same sized file being replicated.
Anyway, I proceeded and clicked create MP3 version and, 'lo and behold' it created one according to the import settings that had been made!
Thanks Jim, you have solved my problem.

How to make a movie from an audio file and 1 static image?

Hi,
I want to make a movie that it is basically an 8 minutes audio file and I want to have a background picture that is static and stays there during the whole 8 minutes of my audio.
How can I do that?
I'm able to add the audio and the picture, however I can't stretch the picture to 8 minutes.
My iMovie version is 5.0.2
Thanks,
Martin

Hi mcanovas - Simply duplicate the picture as many times as needed. In the Photos pane you can extend the pic to 30 seconds, so duplicate that 16 times and there you go!
I hope the audience will stay focused

How to remove noise from a recorded audio file.

I'm a relatively new user. I recorded certain audio files which are noisy(humm or hiss). Can anyone suggest ways to remove noise from that clip? I tried Denoiser but it added further noise artifacts which were unpleasant to hear Need help. And pls dont ask me to rerecord it in a noise free environment!

If you have some cash you go after 'Sonnox Restoreor' or 'iZotope RX'. Otherwise this might be of some help:

How do I move the visual voicemail audio files to my computer (OSX10.4.11)?

I have an excellent voicemail that I'd like to download to my computer. Obviously, these are stored as audio files on the iPhone, but I don't know how to move, retrieve, download them to my machine. Does anyone know how to do this? If so, I'll post the greatest voicemail ever received by accident. Thank you!

No offense to Jose, but he is wrong (for iPhones; old school voicemail is indeed stored on AT&T's system). You can verify this by putting your phone in Airplane Mode, which will prevent it from accessing any server, AT&T or otherwise, and listening to all the Visual Voicemail messages stored on your phone.
So it is theoretically possible to find them and copy them, but unfortunately I have not seen anyone figure this out ... yet.

How do I repair a broken M4A audio file?

I used the program Audio hijack Pro to capture some audio of a Skype conversation. But in the middle of the conversation AHP crashed, and I'm left with an incomplete and corrupt m4a audio file. It is 6,7MB big, which indicates to me that the audio is still there, but not accessible. No program I tried can open the file or repair it.
I tried vlc, quicktime, soundtrack pro, windows media player, fission, audacity and some smaller tools like BeSliced...
Please help, I don't want to loose 30 minutes of speech recording!

If your presentation is such that you want to recover it rather than reconstruct it, you could consult the Apple documentation on the Keynote document structure. That said, I have never had much luck directly editing the XML file, and I have grave doubts about the efficiency of such an endeavour. If you do go about it, I would first try deleting all but one slide from the XML file, and see if you can get the presentation to open at all, then build up the file from there. (Obviously you should first make a copy of the presentation and keep that separate before editing the XML files.)
