Why This Works Better Than Loose Files
Loose M4A recordings from Voice Memos pile up fast. After a few weeks, you have 20 or 30 files with names like “New Recording 14” sitting in your Files app. Finding the right lecture means opening each one and listening for context. If you accidentally tap the wrong file, you lose your place in the one you were reviewing.
A single M4B audiobook keeps everything in order. Apple Books remembers exactly where you stopped, so you can pause mid-lecture and pick up later without hunting for your spot. Chapters let you jump directly to a specific lecture by name. You see “Week 4: Supply and Demand” in the chapter list instead of guessing which recording number it was.
You can also create separate audiobooks for each course. One M4B for Organic Chemistry, another for Modern History. Your entire semester of lectures fits neatly into your audiobook library, organized and searchable.
