![]() VBR mode with this encoder at -v0 (maximum variable bitrate) is good, about as good as Apple's AAC encoder for iTunes Plus/Apple Music at ABR 256. Of course, some material is always going to be difficult to encode and lossless is the only compression that will be transparent This means plenty of fine tuning went into its psychoacoustic masking filters, updated year upon year, with tweaks any time someone finds challenging material that fails the transparency test. This will require repeated blind-testing in a mindfully structured study environment, or at the very least a very keen perception of one's own response levels.įor anyone who doesn't know, LAME 3.99 is a specific iteration of an open-source MP3 encoder anyone can work on the software that goes into it, and it has had a long development. But I would encourage each one to explore their own experience to get a fuller comprehension and self-awareness, rather than just write off the missing sound as negligible before one understands the complexities of their own brain's reaction to what is being experienced. ![]() ![]() What many fail to realise unless keenly tuned in to the nuances of one's own emotional response to music is that even if we are not consciously aware that something is missing our brain is still sub-consciously aware that not all of the stimulus is present.īut as I have said, it comes down to what you yourself find satisfying ~ if your own emotional response is no different listening to Mp3 than it is listening to full-frequency spectrum audio, then it is irrelevant. I am not talking about psychological factors that enter in to considerations when analysing music critically, but the natural way our brains react to even sound that is not discernable from a characteristic analysis, through neuro-processing in the brain. The way humans process sound information happens on an emotional-response level. I can pick it out in blind testing by comparison 100% of the time. My ears find Mp3 to be noticeably "hollow"-sounding, thin, less-rich. In reality an Mp3 can sacrifice roughly 38% of the sound that is present in the full spectrum, through data-compression. ![]() Click to expand.It is up to your ears and these only. ![]()
