Yes, and it's worth planning around. Both formats are lossy, so the AC3 encoder is working from audio that has already been through one psychoacoustic pass, and its own decisions compound the first set. At 192 kbps or above the result is still transparent for most listening. If you have a lossless master anywhere, encoding the AC3 from that instead avoids the double pass entirely. M4A ali AAC m'malamulo ambiri, kapena Apple Lossless (ALAC) pamene anachokera ku lossless rip.
