Handling of MP3 files

I would like to know what I should search/study to manipulate an MP3 file, from its reading to alteration and display;

Some punctual doubts would be:

  • Is there any language more appropriate for this type of use, if yes, which?
  • Within the languages in which it is possible to work with this, it is done more abstractly or is executed with the help of libraries?
  • For the identification of patterns in reading, which would be the most suitable tool?

Your question will surely be closed rsrs

Boy The Decoding of Files mp3 is very complex, this process gives a TCC weightless...

I do not know and do not understand the type of manipulation you want to do, but to manipulate (increase volume, apply filters, change frequency, change speed, reverse audio, move audio to play in a given second or minute, etc.) no escape, you will have to decode to have the data in format PCM

Surely you will have to use some ready lib to perform decoding, there are some LibMad, AMP, LAME, MPG123 all of them are written in C for python27 I know the pymedia example of use in this mine reply, for java has the Jlayer, the vast majority of them are some kind of Fork of libs written in C.

The lib I consider the simplest to understand is the lib AMP, as far as I know was the first lib(free) that appeared on the net able to decode mp3 files, it was from her that came Winamp, some companies used this lib inside embedded systems (mp3 players), it is not very easy to find the sources of this lib, maybe at deepweb, I should have on some 90’s huahuahua CD...

  • Thank you very much, gave me a series of necessary guidelines, in case what I will do with this file will be identification of sound wave patterns. Thank you again so much.
