why does normalizing a file make compression less efficient? 2020-03-11 16:23:14 Hi everyone,This might be a totally stupid question but my DSP knowledge is rather limited so I'm a bit lost...Simply put, let's say I have a file which was recorded at a quiet level, and I convert it to flac. Then if I boost the volume/normalize that file and compress again, the file size is quite a bit bigger. For large boosts the change seems to be quite dramatic. I guess this happens because any noise floor/quantization noise in particular would be stretched into the upper bits, and not rounded nicely, so in effect you're wasting precision, but that's where I kinda get lost trying to figure out if that makes sense or not haha. So I figured I'd just ask about it here. Is there some kind of processing that can raise the volume of a file without negatively affecting compression ratio on lossless codecs?BTW I've read about replaygain though haven't tried it. I'm trying to stay away from it for compatibility reasons; I use flac files for a wide variety of purposes.Thanks for your responses!
