Hello list, i need to read mp3 files in Pd... i use object mp3play~ from iem_lib_mp3 but it doesn't support Layer II...
Can you help me ?
Thank you

Isn't that a contradiction of terms? AFAIK,
.mp2 = mpeg audio layer 2 .mp3 = mpeg audio layer 3 .mpg = mpeg video layer or combined audio/video layers.
(is that wrong?)

Yes mp3 is for MPEG-1 Audio Layer 3 but some audio files with the extension "mp3" may be Layer I or II...
So, when i try to open a .mp3 with mp3play~, it returns "Layer II not supported" Actually, i think the layer is relative to the ratio : ...something like that -Layer I : 384 kbit/s -Layer II : 160..256 kbit/s -Layer III : 112..128 kbit/s

Not at all. You should read the following paragraph in the article. Those are suggested bitrates. Those bitrates are suggested because using just Layer I is less efficient than using Layer II (which uses Layer I plus its own techniques) which is less efficient than using layer III (which uses Layer II plus its own techniques). When using more techniques you can use lower bitrates to achieve the same fidelity.
