Does anyone know if there exists an mp3 to pcm audio data implementation written in pascal?

A few days ago the mp3 format became patent free. A such a few OSS people are writing native mp3 decoders, for example Red Hat. Now I am wondering if anyone has written an mp3 decoder (to pcm data) for free pascal.

For reference, here is a C# mp3 decoder that can convert mp3 data to pcm data in blocks, which is a preferred method.

Hello.

With uos ( https://github.com/fredvs/uos) you may save the mp3 into wav (integer 16/32 bit) or pcm (integer 16/32 + float32 bit).

Hello Anthony,
IIRC a Pascal mpeg decoder is implemented within IAP:

Best regards.

Wow.

I see the code is for Delphi.
Did you try it with fpc ?

There are no demo for mpeg decoder.
Do you know how to use it ?

Thanks.

Hello Fred,
I compiled it a few years ago, but I don't remember which compiler I used, sorry.

IAP is demo itself, but I remember that during my testing it was quite unstable.

Maybe you can contact the author (C.W. Budde) directly for more info, good luck.
