How do I convert AC3 to M4A audio?

Is AC3 to M4A a lossy or lossless conversion?
+
If both AC3 and M4A are lossless (WAV, FLAC, AIFF), no quality is lost. If M4A is lossy (MP3, AAC, OGG, Opus), audio is re-encoded; we default to a high bitrate (192-320 kbps) for near-transparent quality.
What bitrate does the M4A output use?
+
192 kbps by default for M4A where applicable. Use the options panel to pick 96, 128, 192, 256, or 320 kbps depending on whether you want smaller files or higher fidelity.
