That's more of a bit depth rather than bit rate thing. I was surprised to find that going from 16 to 8 bits by simply truncating gave really obvious artifacts on certain sounds (a sampled 808 kick for example had a distinct BZZZEEEOOOOWWWW sound, quite prominent), and even really simple triangular noise dithering made it go away. It did mean the playback was more noisy but it was less obvious. As an aside, G.711 codecs use a kind of log scale with only four bits of signal but small signal values use much smaller bits. |
