I can’t even hear the difference between lossless music and 320k MP3 Part 2
Is it necessary to buy headphones with good sound quality?
First of all, it is worth seeing it this way. Of course, most of the current lossless formats (except WAV format) do not refer to the direct storage of the original PCM stream, and still use a series of lossless compression algorithms to reduce storage space, but no matter how lossless Compression, in general, is definitely not as powerful as “lossy” compression.
Here, we have reached the first climax of the brain, obviously, in addition to using a series of compression algorithms to reduce the storage space of audio information, we can rely on more direct and rough methods, such as switching from binaural to monophonic. In this way, the storage space can be saved basically in half, but it is obviously not worth it. After all, two channel sound is still stereoscopic, and single channel doesn’t have that feeling at all, so we can start. of the sampling precision. , For example, the sampling precision directly reduces to 15 bits, which can directly save 6% of the space.
But in any case, reducing the sample depth must mean that the audio signal is corrupted (in fact, based on the current level of technology, no matter how you store it, the original audio signal cannot be restored)
So how does this “lossy” sound different?
blind listening test
Of course, practice is the only criterion to prove the truth. It doesn’t matter if you can do it or not. We cannot feel that the songs we listen to now are not good as soon as we hear the damage. they must more convincingly identify your sense of hearing. The difference between the two depends on the ABX Blind test.
