Hello at all

I have create a program for manage my numerous records, with image of the jacket.
But like KCC don't have enough memory, he forgot the melody of several records

So KCC have the idea, to cut a little piece of song, and link it with the title and the jacket
I have modify a code found on the german forum, who cut file in several piece.
That's works perfectly
I'm surprising, because apparently a MP3, can it be cut everywhere and it continue to works with winamp

And VENOM give me, a great code for cut a MP3 with FFMPEG, and that's works perfectly too.
But i want to be sure it's the most little file, that i can obtain :roll:
Now for 20 second in 32kbps, 42Khz the file is 80 Ko
But i believe it is again in stereo :roll:

My problem now, it's to reduce the file at his maximum, because i have 6000 titles, and want again more.
And for buy my records y use a EEEPC, and not have a big hard disk, even no hard disk because it's just memory

So what is the better way to convert a mp3, in the most tiny file.
I don't need the stereo, and not need a best quality for a EEEPC...just recognize the song, like if she is in a phone

My friends VENOM, TAZNORMAND, CEDERAVIC, in french forum, give to me a way
FFMPEG apparently it's a good result
LAME, i don't know how can i use this DLL
FMOD, i don't know how can i use this too

I don't know anything at the sound.
If someone have see a code, not too complex, for do this little file, i'm happy to be help

Good sunday at all

I have some old code at home somewhere I think KCC, but unfortunately I am not there at the moment. If you are not in any hurry I will see if I can dig it up for you when I get home in a couple of days?? ( I may not even be able to find it then though. )
Otherwise, try doing a search for something along the lines of ACM decode as from memory, the code I have is based on some stuff from this forum from about 4 years or more back.

Thanks BALDRICK for your answer.

If you have a code, i'm interesting.
I continue to search and perhaps i can compare the better compression with another method :roll:

For me, the most important, it's the size of the file, for 30/60 seconds.
Like on the WEB SITE, when we can hear a little part of a song, that you listen before you buy

It's really an unknow domain for me
I know just run winamp...and click on play

Apparently, convert music it's not easy thing, i'm not at the end of the way
Again thanks for your answer

Again a freeware for convert audio file with command line :
http://sox.sourceforge.net/

So now..i have four method
FFMPEG
LAME
FMOD
SOX

But which choose for someone like me ??? :roll:

I have try SOX, but it's really not simple.
It ask the LibMAD

I have download LibMAD, and she is not compiled

There is not a better simple way for create this short pîece of music ???

Hi KCC,

try XMPlay. It comes with a Disk-Writer-Plugin, which uses Lame or something similar. You have to put the lame.exe inside the same directory as XMPlay.exe.
Then you may set the output-quality to 8bit, mono, 11025hz, and export your file with the disk-writer...
I use this tool for ages now. It's free, and great; based on BASS... btw. BASS for PB should be able to do the trick, also?!

http://support.xmplay.com

KCC, I am back at home now & have had a quick look without success to find my old code. I will keep looking for you as I know it is in some old archive I have here somewhere... )
Anyway, I am pretty sure the stuff I had is based around some code originally ported by Rescator, Here:
http://www.purebasic.fr/english/viewtop ... 1&p=103998
It will need quite a bit of work for you to get it working though I think, but if you can do it, it will allow you to rework your mp3's down to about 6Kb/sec if I remember rightly & the file size can be reduced by upwards of around 70 to 80%. ( I used it to make up some music on an old 512MB Mp3 player & it effectively allowed me to do a trip of around 1,200Km in my car without repeating a song... )

Please remember than if you need to publish your application with mp3 support, you will need to pay a license for it.

@JAMIROKWAI
Ok i try it, it's already a solution if i not found a PB code

@BALDRICK
Never mind, thanks already to have search for me
I go to see your link...perhaps i can do something with this :roll:

@FRED
Yes you are right, it's always a good idea to call of this "little item"
Numerous persons believe that MP3 is FREEWARE, but not

But do not get worried, KCC is not enough good to sell anything
Or perhaps at his mother, sister, father ....

The MP3 is not FREEWARE.....not to be confused with the GIF....it is FREEWARE the GIF now, eh FRED i'm right eh !!!!

@ALL
Thanks at you all for your help

I'm not fixed to a format, where is the better format for compression
OGG, MP3...etc ???? :roll:

I'd said OGG. It sounds better than MP3 at low bitrates, and is absolutely free

And is handled natively by PB !

I don't understand. If we open an MP3 for playback with LoadMovie, then we don't need a license, do we? Because LoadMovie just uses the installed codecs to handle the file; it's not PureBasic decoding them. Isn't that right?

Yes, that's right. But if you include your own decoder, it's not the same.

It's difficult to know all the slenderness of the law :roll:


Someone in the NET, talk about MPC, Monkey's audio for better compression.... :roll:

1/ So like it's to make little piece, for just recognize a song in MY program, then i not need MP3
2/ Like the OGG is better that MP3
3/ OGG is FREE like GIF
4/ OGG is recognize by PB

There is 4 reasons to choose OGG

If someone, found a code or a tips to create this little piece of song in mono OGG, the more tiny possible......
Remember the adresse of KCC

Because KCC, is lost in this jungle of audio, like if he is.... in the middle of the sea

Psst... XMPlay can
You can us OGGEnc, provided on the same page (or via a link) to batch-convert your .wav, .mp3s, .what to .ogg
