What do lossy and lossless mean and which is better?
How are audio files encrypted?
Initially, audio was recorded on a computer in WAV or AIFF format and these took up too much space.
They took up so much space that few audio files could fit on the first hard drives, because they had only a few megabytes of available space.
This still happens today in portable devices in general.
Nobody would think that a service like spotify could transmit and store wavs or files without compression.
It could not have the transmission speed, it would spend too much bandwidth and occupy the disk or storage space right away.
If we talk about videos, the same would happen with Youtube or Ntflix.
So, initially almost desperately, they looked for ways to save space, even if this had some impact on quality.
Over time, the Internet’s transmission capacity improved and different compression methods made significant progress.
Lossy
Initially, the hearing capacity of the human being was used to, in addition to compressing the files, also discard non-audible information.
Many people wonder why 44100 was chosen as the samplerate for CD discs and the first more or less obvious answer is that if the human ear is capable of hearing sounds between 20hz and 20khz then more or less twice as much was needed to be able to manage and store audio with good quality.
