- yorwba 9y agoAlso pedantic, but lossless mp3 compression is possible; it just requires the decompressed signal to be identical to the original.
- anamexis 9y agoMore just having fun now, but I feel lossless compression implies deterministic decompression, i.e. there is one and only one signal which compresses to a given compressed signal. Even if you had a signal which compressed to itself, it seems to me that there would likely be other possible signals which would compress to an identical compressed signal.
- yorwba 9y agoGood point, even if compressing and then decompressing does not change anything, you need to know that nothing changed, otherwise you lose information about the compression error.
