Why my 30 second audio file size changed from 500K to 150K?

Car stereos can be pretty picky on what format(s) and bit rate(s) they will handle. Computers are much less so as they have multiple codecs to handle many different file types. And just because a file has a .MP3 extension (or anything else audio related for that matter), it is no guarantee that the song is actually IN that format. Again, computers look at the file, not the filename extension, to determine what type of file they are playing. Stereos are not computers, and as such have limited range to handle these files. Check your music for file type and bit rate and compare to the stereo specs. If they don't match, there are some free programs (Audacity is one), that can do some format and bit rate changing to make some types of files compatible.

Apple's iPod Touch does not support Windows Media Files. You will have to convert the files to a compatible format.
Support Media Formats (located at http://www.apple.com/ipodtouch/specs.html)

• Audio: AAC (8 to 320 Kbps), Protected AAC (from iTunes Store), HE-AAC, MP3 (8 to 320 Kbps), MP3 VBR, Audible (formats 2, 3, 4, Audible Enhanced Audio, AAX, and AAX+), Apple Lossless, AIFF, and WAV
• Video: H.264 video up to 720p, 30 frames per second, Main Profile level 3.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file format; Support for 1024 by 768 pixels with Dock Connector to VGA Adapter; 576p and 480p with Apple Component AV Cable; 576i and 480i with Apple Composite AV Cable (cables sold separately)

Are you certain that you're recording in MP3 format?That large file size seems much like .wav files than .mp3 thing.


But if that's really .mp3 file,you may need to adjust the bit rate&sampling rate.Typically, 12 kbps and 44.1 KHz would be a good starting point.


And about shrinking files you've already done,try file convert software(s) around the web(try Google it).Too many of them to recommend here.But I personally use Wavepad Sound Editor for record,edit and save files in various format.

Thw bit rate is way too high!...
The other wav files you g=have are probably around 128kbps.... that files has 1441kbps.
You also reached the 2GB file size limit...
The other files are probably less than 4MB.


See if you can change the bit rate to 256kbps or so...

Hope this helps!

below link have file for ur help..

Youtube imposes a maximum limit of 10 minutes duration for each video and 100 MB max file size. Since your vids are under the 10 min limit, you should look at the file size as the offending party. If it is over 100 MB, thats the problem. To reduce the file size you need to understand what a CODEC(COder-DECoder) is and how CODECs can be used to make video files smaller for uploading to Youtube. The file you want to up-load has two parts, audio and video, Each part uses a different type of codec to encode and save the "movie" you created with your video editing program. The most common and efficient video/audio codecs used on Youtube are MPEG-4 and MP3. If your video app is not set to encode audio to MP3, you are probably encoding the audio into a raw uncompressed WAV format (pronounced wave). Uncompressed WAV files are very large compared to the MP3 format. Setting the audio bitrate can be confusing. To keep it as simple as possible, I suggest setting the Bitrate to 128 kb/s STEREO if the video has music or 96 kb/s MONO if it is just people talking. Set the Sampling rate to 44100 Hz (or 44.1Khz) AAC is another Audio format. The same sampling and bitrates apply. The next thing you want to look at is the Video resolution and type of file you are saving/recording to. Since you are recording from a webcam, you may be using a propriatary codec that came with the camera. If this is the case, then you need to let me know what brand camera and software you are using. Most video cameras, including web-cams, use non-proprietary formats that can generate very large (but high resolution) files. For example: .avi & .mpg. You want to record at the highests resolution you can, BUT, you will save it later to a lower resolution compressed file. Many webcams can record at 800x600 and 640x480, but the file you will save for Youtube may be 320x240, 480x360 or 640x480. The higher the numbers the higher the resolution, but also the larger the file size. Also, the more motion there is in a video, the larger the file will be. So, if you have a lot of action and need to "squeeze" it in (compress) the video, use a lower output resolution (320x240). If it is an interview type video, where the background stays the same, you may get away with a higher resolution (640x480) if you want a sharper image. When recordings from the camera are saved as .avi, .mov or .mpg, you will have to change the output format in your video editing program to mp4 (H.264) format. You may also be able to set your webcam to record directly to the mp4 format, which would be ideal, if you do not plan on editing your video. Then you can simply record and upload. The bottom line. ------------------ When you are done editing your movie and are ready to save it. Find where you can set or change output options in the editing app. Set the audio and video bitrates and resolution to those best suited to your needs. Change the output type to MP4, aka H.264 (for video) and MP3 or AAC (for audio). Click save, wait a bit, upload your video to YT for the world to see and revel in the glory of being a producer.

WHat up? Ok to get the ringtones to your phone (which I have searched for two days to find a solution) do the following

1.) get your desired .mp3, or .mid ringtone file and have it on your pc.
2.) log into your email (yahoo, hotmail, etc), create an email and attach the .mp3 file. Make sure the .mp3 file in under 500k in size.
3.) in to TO: box enter the following ,<yourphonenumber>@mymetropcs.com and send it.
4.) check your message box when your phone chimes.
5.) press the Get button to download the file to your phone. If your file is over 500k it may not download.
6.)Now go to your inbox
7.) press the Browse button to stop the file from playing.
8.) make sure the file is selected, press the Up button (Top outter ring of the middle menu button)
9.) press the options button, select "use higlighted object" and save it to your phone.
10.) the file will now be in the MyTUnes folder and you can now set it as your main ringtone or a contact ring tone. (I'm typing this from memory so my menu selection names may be off a little but this shold get yall going. I was HYPE when I found this solution. I'm now searching on how to get the games on it.

Hope this helps!

You can't actually do that.
If you have the original version Katana, the 6600, it's only plays polyphonic ringtones, in the qualcom format of QCB.
Freeringers.net has a good help section if you sign up with them, here's a cut and paste version.

You basically need a program to convert an mp3 to a wav file format. (like dbpower amp but there are many others, alot of them freeware).
Sound recorder on your computer applications, to pick a segment and crop the audio. Usually about 30 to 60 seconds is good enough. There's a file limit size on the Katana for downloads of about 100kb.
And a converter program that will convert wav to qcb. You can download an application from Qualcom Communications for free, or this little program called purevoice.
http://www.freeringers.net/apps/pvconv.exe
All you do is little drag the wav file over this application and it automatically compiles in about 3 seconds, a qcb file into the same folder.
http://www.qctconnect.com/products/purevoice_downloads.html
Provides the full version of purevoice convertor so you can listen to the quality of the qcb file.

You'll need an application to convert the MP3 or CD to a WAV file. We suggest this free tool:
dBpowerAmp Converter 10.1 (Download and install it)

You'll also need PureVoice for QCP conversion:
PureVoice Converter (No installation. Right click "Save Target As...")

If you're running Windows Vista you'll need the Windows XP version of Sound Recorder:
Sound Recorder (Right click link, "Save Target As...", save to "C:\Windows\System32\")


Conversion Steps:

Note: If you want to rip a song from a CD, replace step 1 with these instructions.

1. We'll assume you're converting a file named "test.mp3" for this guide. Insert your own file name instead. Run dBpowerAmp and select the "test.mp3" file and click "Open".
2. Change the drop downs to "Wave", "16 Bit (CD)", "8000 Hz", "1 'Mono'", Output To: "Folder", and "Browse" to select your "Desktop".
3. Click "Convert >>" and once it's completed click "Finished" and you'll have a file named "test.wav" on your Desktop.
4. Run Sound Recorder (included with Windows) and from the "File" menu "Open..." the "test.wav" file created in step 3. (if you can't find Sound Recorder, see Needed Applications above)
5. Shorten the ringtone to 30 seconds or less. You can also crop it so it starts at the beginning of the choirs. To crop the audio clip, use the "Edit" menu to "Delete Before Current Position" or "Delete After Current Position". [?]
6. Click the "File" menu and select "Save" which will overwrite the "test.wav" file.
7. Grab and drag the icon for "test.wav" and drop it on top of the PureVoice icon "pvconv". It will convert and create a new file named "test.qcp", almost like magic.

if your mobile supports OGG format. then you can convert MP3-OGG format. OGG format can hold 200 songs on 1GB memory card. use Mp3-OGG convertor.Similiarly you can also AAC format. But compared to OGG AAC files requires bit more space
