AAC becomes "transparent" at a bit rate of 64 kbps per channel, so that's why the bit rate is 512 kbps here, since there's 8 channels. Transparency means that there would be very little or no difference between 512 and 1000 kbps in audio quality for 8 channels, and only an unnecessary increase in file size. So the audio's bit rate may look insufficient, but in reality it very much is
