MP3 MIXER implementation

[Nikson_]

Hello, Gents!

There are any ways to play several mp3 files at the same time? My project required mp3 mixer implementation.

How it sould be:

==========first_mp3 file=============================================
.......====second_mp3 file===..........................................................
...................=====third_mp3_file============.................................

<-------------------------------------time representation------------------------------->
legend:
= means Playing in the Loop
. means not Playing

mp3 files will be stored on the external SDcard
Will be used external DAC module with I2S interface

I saw downmix feature, but it's seems that it can handle only 2 pipelines (i.e. sound files)

Please give me some idea how I can do it.
