MPEG-2.5 Layer 3 to MPEG-1 Layer 3 using LAME 2019-11-20 02:08:03 I have some old recordings that were encoded as MPEG-2.5 MP3s, 32kbps, several years ago. I'd like to convert them to MPEG-1 MP3s for maximum compatibility. I recognize this will require upsampling, but what else would be necessary?I'm only willing to do this if it can be done "losslessly" (or, more accurately, without further loss of data). From what I've read and seen of LAME, it appears that the stream would have to be decoded into WAV, upsampled, and then reencoded as MPEG-1 which definitely would be lossy. Am I wrong about this?
