extend a mp3 music!
« on: October 02, 2014, 10:09:56 AM »
Hello! i have a 17 sec mp3 file, that i want to insert into a slideshow presnetation , which is 3 min's long.
Is there any application, that can make a 17 sec music last till 3 min.
What i mean is repeat that same music over and over again like a loop for 3 min. Also can i remake the entire music with the volume slightly reduced.
Few programs come to my mind and one is Audacity.
Hope it is understandable.

My software does it (mostly). Send me the file and I'll get it back to you looped for 3 min exactlly.

What you're asking for can only be done in looping software or a DAW.

Some good examples of software that is well suited are:

  • Fruity Loops
  • Saw Studio
  • Samplitude
  • etc.

For the volume reduction, that's a bad question. You need to know where it will be mixed, and the best thing to do is to mix it in there with the volume reduced.

^ Looks like Ren has it covered but will post this anyway:

The first thread on the list there will offer a few options for looping:

Reducing the volume can be done by mp3gain:

(normally used to standardise volume of multiple tracks)

Thank you Renegade for extending your hand.
But i already looped the music and converted the music to wav and further converted it to mp3 by using iWisoft Free Video Converter.
The only thing remaining is to lower the volume of the music.

@tomos : Thank you for the link, i am checking on it.

Here is the music:

You're doing everything wrong.

You want to go from MP3 to WAV and do everything there, then mix it in with anything else that you need to mix with and reduce the volume then. Not before. Not after.

If you go MP3 > WAV > MP3 > mix > MP3 you will have audio degradation that you can avoid.

The fewer steps, the better, unless you are purely dealing in a lossless format like WAV or FLAC. I wouldn't recommend ALAC or RIFF.

But, then again, you probably don't need the best audio quality you can get either. Good enough is enough a lot of the time. :)

This file is reduced by 6 dB. So, it's significantly quieter. I kept it as an MP3. Not sure if it will be quiet enough, and I'd still recommend reducing volume in the mix instead.

Using the "ReplayGain" function of the .mp3 format, you can do a lossless reduction of gain, that is, if your presentation software supports the ReplayGain function.  It's just a tag in the mp3 header, so any mp3 tag editor that supports the ReplayGain field will do:

Mp3Gain can apply the same sort volume normalization via psychoacoustic analysis that the ReplayGain function does, and does a handy job of it, whether on Windows, Mac or Linux.  The only caveat is that it manipulates the file directly, so it's technically not lossless though it is reversible:

Some lossy audio formats, such as MP3, are structured in a way that they encode the volume of each compressed frame in a stream, and tools such as MP3Gain take advantage of this for directly applying the gain adjustment to MP3 files, adding undo information so that the process is reversible.

i was able to achieve both the extension of 17 sec sound to 3 min and reduction of the volume by Envelop tool and i got the desired results.
For a simple and free tool like Audacity,it does more than those expensive application. Although not underestimating them, but sometimes some
good things come for free.
I got what i wanted for free. Anyways thank you all for your reply, i got some insight in this matter and will help other when the need arises.
