The folks at OCTiV clearly have a thing about noise. Witness the $50.00 Terk VR1 which apparently overcomes the ‘too loud-too soft’ syndrome with television viewing (although this review doesn’t seem too encouraging).
Take a look also at the company’s Winamp plug-in which promises the same level of automatic volume level control for playlists.
‘Low levels are intelligently raised and loud signals are kept under control, all in real-time, all with the smoothness of butter. Your music will sound dramatically enhanced and you will enjoy consistent volume levels for any playlist you create.’
