Compress audio file to mp3 or aiff of 5 MB?

Hello,
Does anyone know if I cam compress an audio file on GarageBand for the iPad 2? I'd like to take a file 30 minutes in length and be able to email it, so I need to compress it to 5 MB or less.

only thing I can think of is "share with iTunes" and then once the file is in iTunes, compress it again there, by going to iTunes -> preferences and on the general tab, about 3/4 of the way down, click Import Settings and then set your settings to MP3 and then choose custom from the settings drop down and then choose a really low kbps bit rate. You may have to experiment, I haven't had coffee and can't do the math right now to suggest a bit rate for a 30 minute file becoming a 5MB MP3. Good luck!

It's 2013 and I want to convert AIFF audio files to MP3s

It’s 2013 and I want to convert .AIFF audio files to .MP3 files on my Mac.
I created some sound files as .MOVs for a band’s website but that format doesn’t work for some Windows OS users who refuse to fetch a QuickTime plugin for their Explorer or Firefox internet browser…("don’t make them think; it either works or it doesn’t.")
I have been told that MP3 audio files are still the most common audio files on the web and I want the band’s music to be in the most-accessible format.
Thanks,
Ron
Also, this is my first Apple Support question and I would appreciate being pointed to the most appropriate forum(s).

Thanks, Joe, that was very useful!
For other people with my problem I should add some of the missing puzzle pieces —
1) A while ago I loaded the songs from the band’s CD onto a previous, now dead, Mac laptop (with a previous Mac OS) and used QuickTime 7 to create down-sampled (and smaller) .mov files. Then I deleted the original .aif files from that computer.
2) Now (back to the present) I wanted the .aif audio files on my new computer to convert them, but the computer doesn’t have a CD/DVD drive. My solution was to use my partner’s iMac.
3) I inserted the CD into the iMac’s drive, clicked "no" to iTunes’ dialog asking if I wanted to import them, created a folder on the desktop, then opened the CD folder on the desktop and copied the songs into the newly-created folder.
4) I copied the new .aif files to a thumbdrive then deleted the .aifs from the iMac.
5) I put the copied thumbdrive .aif songs onto my MacBook Pro Retina (where I had changed iTunes Preferences to MP3) then I 'dropped' the sound file icons onto the iTunes icon in the dock.
5) In iTunes I right-clicked on the songs and chose "Create MP3 Version".
6) Next, I right-clicked on the MP3s in iTunes and chose "Show in Finder". This opened another folder (~/Music/iTunes/iTunes Media/Music/Unknown Artist/Unknown Album/), revealing the MP3s.
7) I created duplicates of the MP3s and moved them to my band's media folder (and will put them on the website after renaming them and editing their webpage for the new audio filenames).
8) Finally, I will delete the .aif and .mp3 songs from my iTunes, using iTunes' interface to ensure it doesn’t get confused.
Sheesh. but I’m still happy to not have a CD/DVD drive on my MacBook Pro. I very rarely use CDs and a drive on the laptop would add bulk and weight while being mostly useless.

Compressing Audio Files-Help please.

Will compressing the audio files held on my hard drive in itunes meen that they can still be played as normal and will it have an effect on the synchronization with my ipod.

By compressing, I assume you mean putting them in one of the standard formats, namely mp3 or AAC, but at a lower bit rate?
If that is what you mean, then the answer is yes, you can still play them as normal. You will lose some audio quality due to the sonic information lost in the compression, so don't go do it wholesale until you have tried and assured that you are happy with the results.
(If by compressing you mean something else, e.g. zipping them, then don't bother, since they will not compress much and will not be playable until you unzip them.)

Compressing audio files in Macbook

I'm trying to do something new - compress audio/mp3 files to send via email or on the website. I've used the 'right click' on my mouse pad and clicked on compress file, but a 24 meg mp3 file was only taken down to 23 meg.
When I used a windows notebook I had a 3rd party software called DietMp3 which really reduced the size of the file.
Does Mac have a native program or is there a good 3rd party program to do this?
One more: Is a .wav file smaller than an .mp3?
Thanks for your help!

You could re-encode the track in iTunes at a lower bit rate.
Just change the setting in iTunes preferences to a lower fate and then select the track you want to compress. No use the Create ACC version command you will find in the Advanced Menu. The file type shown (i.e. ACC or MP3) will depend on the settings you have selected.
Basically the DietMP3 software you use was just encoding the file at a lower bit rate, that is the only compression you can do.

How do I convert .dcf audio files to mp3 so i sync...

HI
I have an 5230 and have just got a USB cable so am able to connect with Nokia PC Suite and also Nokia Ovi Suite.
I have bee able to send all my music files over to the computer but some of them won't play as they .dcf files and this computer can't open them without the appropriate software which it does not have, (FYI - it plays fine on the phone and shows in the ovi music player libarary). I have looked on google for software to convert the .dcf file to mp3 but as yet have not found one that will convert from this file type.
Has anyone else had this same problem and do you know how to fix it or where to download convertor programme that will work?
Thanks in anticipation of your help.

Emagic's "ZAP" program - archived compressed audio files unable to open.

I have a number of audio files that were compressed/packed using emagic's ZAP program that I was interested in revisiting but it seems my copy of "ZAP' has run out of authorisations over the years through computer meltdowns. Does anyone have a solution to this problem?
Thanks.

Yeah, I think I have a copy on my PC, or if not, I could probably dig it out.
There was a free unpack-only version of Zap that should enable you to get at your files - though where you could locate a copy I don't know. It might have been included on Logic master disks around V4.x.... It would probably be OS9 only I guess, for the Mac version.

Converting from Quicktime/Midi audio files to MP3 format

Before I upgraded to Tiger, I could use itunes to convert into mp3 form all the Quicktime Midi files that my chorus director emailed to me. Then I burned them on to cds so that everybody in the chorus could play their part in their car on the way to work and learn it really well.
Well, now when I go through the exact same steps that are on the website (go to preferences, go to advanced, change encoder to mp3, etc etc) and itunes says that it cannot convert the file to mp3 because of "unknown error (-50)."
Any ideas on how to get around this other than trashing my Tiger and going back to Panther?

I bought and downloaded quicktime Pro and used it to convert my MIDI files. First you have to find your MIDI file on your HD. Then drag it into QuickTime. Then "export" the file and in the export window select aiff as the format. Save it to your HD. Then drag the aiff file into iTunes and it will play in iTunes (6.0.4 is the version I'm using) It will also burn to a CD from within iTunes. If you only want to play the file from within iTunes, you can skip the QuickTime conversion, and simply drag and drop the MIDI file from your HD into iTunes - iTunes will play it but won't allow the file to be burnt to a CD.

Automating conversion of audio files to mp3

I often use itunes to convert aif files to mp3.. What I would like to do is to automate the process. Is there any way to get itunes to check a folder and convert all files in it to mp3 files?

Nope, iTunes does not "watch" folders at all.

Conversion of Mpeg4 audio files into mp3

I recently purchased some songs with the aim to include them in a movie I'm currently editing re my vacations.
The edit software I'm using (Magix video de luxe 2007) doesn't allow to include these songs. I tried to convert the items into mp3 (using iTunes features) but the answer was that the item couldn't be converted as it itìs protected. I unsuccessfully tried to find a solution to my problem in the iTunes sites. It seems impossible to contact iTunes to get an answer. It seems unfare to allow purchase of an item when this can be used only to be listened to! Is there somebody who can help me?
Thank you.

You can't do anything with downloaded apple itunes tracks apart from play them. If the music you need is that important download them as Mp3's. A much more flexible format.
The French government have tried to make Apple make it's music more flexible but Apple would rather stop selling tracks to France than give up their code.
What peeves me is here in the UK we pay 99p($1.47) for each track while in the US it is just 99c. I still prefer to buy CD's, at least I can re-sell them on ebay and recoup some of my outlay and I can do anything with the tracks. On itunes you get nothing for your money.

Compress audio file?

I need to make my podcast file much smaller. It's now 45MB, and it needs to be about 10MB.
I changed the output to Mono in the Preferences.
I haven't found anything else helpful in the Help Viewer/Help menu.
Am I missing something? Any ideas? (any 3rd party apps?)

.mp3 compressed audio stream dose not play in AIR

Hi All,
We are trying to load stream audio file with mp3 compression in the AIR app using the follwoing code using FLash CS4 -
var snd:Sound = new Sound();
snd.load(new URLRequest(""http://67.159.30.133""));
snd.play();
This works fine when we publish for flashPlayer 9/10. When we try to publish it using AIR the sound dose not play.
We have tested with another approach, where we are loading sound with .flv compression. Here we are using NetConnection and NetStream method to play the sound. With .flv compression it works well in both flash player version as well AIR versions. On the other side when we try to use NetConnection and NetStream method to play .mp3 compressed audio stream it dose not pl when we publish in AIR or flashplayer.
If anyone having any info to play .mp3 compressed format in AIR file will be very much appreciable.
Regards,
Kaushik

Published with audio files, AAC Okay, MP3 'No Go'

Hello all.
I've put a couple of music, excerpts on my iWeb website; I discovered something after I published, one audio file is AAC and it loads properly on Safari on all my 3 macs (iMac at home, Office G5 via office intranet and MacBook in office with cable modem), but the audio file with MP3 has just the 'QuickTime' logo on it, you can't even play the music.
Which is "funny" because I thought with Safari and QuickTime, should be able to play all formats of music? At least AAC and MP3? The music files are all encoded or re-encoded respectively via iTunes.
I decided to use MP3 instead is I am afraid some browsers or computers (older maybe?) will not be able to play AAC files?
Thanks and cheers

iWeb writes page code to use the QuickTime browser plug-in so it wouldn't matter what audio format was used (as long as QuickTime supports it).
The trouble is a "Fast Start" problem with your .mp3 files.
Most exports from iTunes uses the newer .m4v or .m4a file extension and they should fast start (play as the file continues to download). You should consider exporting your .mp3 files to AAC (using the same settings currently used in them).
Your page visitors would need to have QuickTime installed no matter what format you used so trying to "help" them by using .mp3 files is lost in the iWeb page coding.
You'll also realize a file size savings on most of your AAC conversions versus using MPEG-1 Layer 3 format. These smaller file sizes help speed up your download.

IWeb and MP3 or audio files

Just got a Mac and looking at the information for iWeb, it talks about text and video, but nothing about audio files, like MP3.
I assume I can upload MP3 files (my own) using iWeb, but just wanted to confirm that before I purchased it. I have my own web page now and would like to redo it with iWeb, but obviously I want to include my original MP3 files in the web page for others to hear and download.
Thanks
Rockhound

iWeb writes page code that will play your MP3 files using the QuickTime browser plug-in.
If you need to use another plug-in or player you'll need to use the special "snippet" code feature.

Cleaning up batch audio files

Hi, new on this forum here. Any help would be appreciated.
I have over 1000 audio files in mp3 format at 96 bit. The audio files are normalized at 95.7. These files are preaching sermons at about 2 hours in length a piece (by the same person). They were recorded through the 1950s to the 1960s. The earlier ones were poor in quality while the later ones became pretty good. I would like to set the bass and treble equalization on all of the files to a decent level, and then take out some of the background noise in the earlier ones.
How would I go about doing this? Is it even possible?
Thanks,
Andrew Carter

As a listener, I wouldn't expect a sermon recorded almost 60 years ago to have pristine audio characteristics. With that, like a jazz song from the 20s or 30s, I'd be more concerned with content and would ignore hums and clicks.
Since they are going to be poor audio quality anyway, you aren't going to lose much if you open them, process, and resave as an MP3. Yes you will lose quality, but since they're compromised already, how much worse are you going to make it? What you can't do - in my opinion - is process them with a batch file. What you are trying to do is far to program content (ie sound quality) dependant.
What I would do is open the files one by one. Apply Noise Reduction after capturing the appropriate noise floor. Parametric EQ, mostly the hi and lo shelf for a little brightening, then Dynamics Processing to compress the dyamic range a bit to let it be more audible on the soft passages. Save the files as mono MP3's to save space and stream easier. The sermons from my church recordings are 44.1/48kbs mono MP3 files and they sound OK for what they are ... they serve the purpose they were intended for.
The EQ and possibly the dyanamics could be done via script (dyanmics only as the source files have already been normalized). Noise reduction should not be done by script, as I think it works best by capturing individual noise floors per file.

Why are some "caf" files colored green and some blue. I need to change the blue (audio) file to a green one so that I can print the sheet music.

I've been trying for days to convert blue audio files (caf in garageband) to green files, so that I can print out the sheet music for that file. I've converted the "caf" file to mp3, wav, aiff, even midi - but nothing will load in garageband as a green file. I get them to load as blue audio files but not as green files. I know the difference between the blue and green files, but why do they both have "caf" extensions? I am trying to conver "piano ballad.caf" to something that will show up as a green caf in garageband. I can't believe there isn't someone who has been successful at doing this sort of thing.

Thank you, that was helpful, it has given me some avenues to explore. I have not used a command prompt for about a decade!
The command chflags hidden /volumes/HomeShare does not seem to have worked.
When I use it, there is no error message but I cannot see anything additional in the other computer.
When I use chflags hidden /volumes/HomeShare/rubbish I see an error message about the folder not existing (which it does not!) so the path is correct.
When I use chflags hidden /volumes/HomeShare/MBP naming a folder that does exist and was created by this computer/user, it seems to have no effect either.
Looking at one source of OS X command line commands (http://ss64.com/osx/) I see that 'setfile' might do the trick (setfile v /volumes/Homeshare/MBP) but that command returns 'command not found'. It is apparently part of 'developer tools' ... which I do not have access to (AFAIK).
In both cases, would the commands work on existing files only, or would new files be visible, or even files copied into this space? Presumably, each person saving to this area would need to then give access via terminal (or a script). Am I right in this thinking? If so, how would I modify the properties of the drive so that they are the same as, for example, a memory stick?
