Re: [mad-dev] .raw file size

I have noticed that that the .raw files generated by minimad and madplay differ slightly. For example, decoding a small .mp3 file the result was: 2428416 with madplay 2433024 with minimad

What is the reason for this?

I think you have these numbers reversed; normally madplay may be able to decode an additional frame over minimad.

The reason is that the API for libmad requires that whole frames be followed by at least MAD_BUFFER_GUARD (8) additional bytes in order to be decoded. To ensure this property, madplay handles the end-of-file condition specially. For simplicity, minimad does not.
