You are right, but don't forget that by "512kbps mp3" you probably mean
stereo file, while ac3 has 5 separate channels + small lfe channel...
That makes real difference.

640k ac3 is used for dolby cinemas. Maybe its quality won't be ideal,
but at least it would be closer to 768k dts than 384k ac3 one...
