Hi. When editing audio I quite often see the 'waveform' looking like the first one in this pic i.e. just a solid block: A more normal waveform should look like the second one in my opinion (both songs here are heavy rock). I understand this is something to do with making the recording as loud as possible at every point - is that right? And, if so, why is it that recordings with a 'block' waveform still sound fine (to my ears anyway...)? Many thanks.
