what do you mean by this? do you mean the equipment used would give this lossy or lossless result?

and whats the difference between compressed and lossy?
lossy is lossy, but does compressed mean lossy because its compressed or what?

In regards to these 70's shows (which I'm guessing were/are analogue recordings:-
"Equipment used would give you this"= the recorder+mics+pre-amp(if used) that was used to tape the show. Different combinations of equipment will give you different results. Also, different combinations of the settings of the equipment used will add to the mess.

1970-12-19 + 1975-09-04 are lossless but the quality of the recording (the fullness of the audio spectrum through to @ 20 kHz and above (which are useless to us humans), compared to what you can find nowadays, is different.

Lossy= Quote:"Lossy compression is a data reduction method that reduces the amount of data during the coding process, but retains enough information to be useful. For example, an MP3 file is a lossy music file that discards some of the original data but is still acceptable for music listening. The advantage of lossy compression is that the music file takes much less storage space."

Basically lossy is the loss of information (that cannot be returned to the individual file). You can compress a file without making it lossy but too much compression will make it lossy.


Look it up on Wikipedia!
