> based on the rise in ampltitude The apparent rise in amplitude is horribly annoying; but I understand that actually increasing the volume during ad-breaks is forbidden (at least in the UK). Instead, they tailor the audio spectrum to create psycho-acoustically the impression of increased loudness. Automated ad-filtering on broadcast TV seems to be a hard problem. Some filters look for the channel logo screen at the start and end of the ad-break; but (a) you have to set up each channel; (b) "sponsors" now book slots at the start and end of the break, before and after the channel-logo screen. The best solution I've found is to record anything I want to watch in advance; then to skip forward 5 minutes when the break starts, and FF/RW if I land in the wrong place. I'm a bit surprised that so many people seem to be buying big-screen TVs, but apparently not STBs with hard-disk recorders.
