I am not an mp3 lilstener; you can hear a difference there. These 512 mp4 files are way better than you think
I already listened several times and tried to make out a difference and could not;
OK, Mr. Audio guy, you think the rest of us here aren't????? Besides answering you, I'm removing an organ sound from a single stem (track) of a 24-track multichannel recording using spectral editing. The multichannel recording was done at 96kHz, 24-bits with PCM encoding.
So, is that enough of an "Audio guy" for you?
AAC (Not mp4 - it's called AAC and if you want to differentiate between the older AAC versions you can say AAC/mp4) is still lossy. It is much better lossy than the older AAC and certainly much better than MP3. But, it is still lossy and I can still hear a difference (yes, I have an iPod). The high end (high frequencies) are a bit too bright. The mid-bass is a bit too muddy compared to the original wave files, but I have to listen closely to hear that difference. But, it is still a lossy file.
Even CD encoding can be insufficient which is why 96/24 is often used for higher quality recordings. It is also why I asked you about DVD-Audio discs earlier.
Anyway, we are well off subject, so I'm going to stop. I'm glad you found a format that you don't notice a difference.
