For podcasts/interviews, I like to download/extract the audio in m4a format. (yt-download is great for this.) If you simply rename the file extension as an m4b file, Apple (iPhone) treats the file as an audio book. This gives a few immediate benefits: - Your timestamp in the file is automatically bookmarked. If you stop in the middle of the file, the next time you open the file it starts at the same point. - You can jump forward/back 15/30 seconds. - You can control the playback speed: 2X, 1.5X, 0.5X, etc.
