Our ears and minds can't separate events that close in time. It's how we've been evolutionarily primed to react. In the same fashion above, if two sound events occur within milliseconds of each other, we're only going to be able to focus on the loudest one. They don't need as much detail encoded in them during those times. What this means is that we can spend lot less data on the quiet sounds. Basically, if a loud sound is blaring out over the top of a lot of low-volume sounds, you're naturally going to focus on the loud sound. This refers to something our ears and brains do called simultaneous masking. In most cases, we don't need to have it at all or at least can encode it into the MP3 file at a lower resolution. It's just "sparkle, shine, sheen." Left: Uncompressed Audio Spectral Image. At that level there's not a lot going on in terms of intelligibility. Adults begin to lose their capacity for hearing above 16-18 kHz, whereas the top limit for humans is around 24 kHz. The first and easiest savings are to go ahead and cut out a certain frequency range if the music allows for it. Using this info, we know what we can get rid of, data-wise. The brain uses certain tricks like auditory masking to allocate resources and attention to what is the most important sound happening at any given time. Psychoacoustics refers to how our brain interprets sounds.
The people who designed these compression algorithms used our knowledge of psychoacoustics to manage the data bandwidth. How Does MP3 Compression Save So Much Space? In fact, MP3's are just the 3rd layer set apart for audio on the video files. MPEG is a video file type that did the same thing for videos as MP3's did for audio. It's also a huge space and bandwidth saver for online streaming services.

Plus there's no need for full resolution files when we're doing yard work or at the gym using tiny sports earphones. They have limited hard drive or flash drive space, so with compression we can carry around a lot more music. MP3's are maintaining their presence due to MP3 players like the iPod.

Instead of waiting days to download a song, we could do it in a couple hours (and in the present, a couple of seconds!). This was preferable when our bandwidth speeds were extremely low on dial-up modems and we might of even had bandwidth caps for the month.
But after being run through the MP3 compression algorithms that might drop down to 3 MB without any serious loss of quality. MP3 encoding represents massive savings, even more at 128 kbps bit rate.Ī typical uncompressed wave file might be as big as 30 MB for a typical 3 minute song. MP3's became a "thing" after the explosion of the internet. We had vinyl records, 8-tracks, cassette tapes, and compact discs (these are digital but didn't need compression). Nobody cared about this stuff when we were working in the analog field. It's been a good 15 years since I spent time thinking heavily on the topic.

I can answer this plainly only thanks to having spent a lot of time worrying about how to distribute my own music across the internet, and of course after refreshing myself. Can you explain how this mp3 compression works, because obviously the compression algorithm is leaving out some data to make this happen, right? What I didn't notice was any drop in quality. I only noticed because the file size itself was much smaller than the uncompressed wave files I've created myself. I bought an album online recently and it was delivered as a 160 kbps file.
How Are MP3 Files Smaller But Sound Good? Question: Sadly, it also sums up most of the explanations out there. Clarkeįor most of us, the quote above perfectly sums up the mystery of MP3 compression. "Any sufficiently advanced technology is indistinguishable from magic." - Arthur C. I actually searched around the net before sitting down to write this and noticed that everyone was writing novels about the topic but nobody could explain it in a quick, normal-person manner. How does MP3 compression work? That's a common question that deserves a fast answer.
