16kpbs Opus audio with chapters is ready for prime time. I suppose it always was perhaps even in 2020. Opus audio codec is superior at lower bitrates compared to AAC, mp3, vorbis, etc. Anyone can create opus 16kbps chaptered audiobooks with freac (GPL free) which is key for wide adoption.

I've been a fan of m4b chaptered 32kbps AAC audiobooks for awhile. Used m4b-tool to create hundreds of m4b audiobooks which is too complicated for the average user. Currently most developers of apps only support mp3 and m4b audiobooks but I believe it'll change eventually.

Make an Opus chaptered audiobook

1) It’s super easy for anyone to create a Opus chaptered audiobook using Freac freac.org which is GPL free on Windows, Mac and Linux. Drag your m4b, mp3s or opus files into freac and export to opus and set maximum bitrate to 16kpbs. Under Tag tab Artist = Author of audiobook and Album = Title of audiobook. Add a cover if you wish.

2) freac General Settings, Opus Encoder Settings, Tag Settings

3) freac main window setting Author of audiobook, chapter names, Encode to a single file, output folder

4) freac Metadata tags for Artist and Album, Cover, Encode

5) Update Cover without re-encoding with TagEditor

6) Playing Opus chaptered audiobook with VLC on Windows, Mac, Linux

7) Playing Opus chaptered audiobook with VLC on iOS, Android and Settings

8) move opus audiobooks from downloads to VLC directory in Files on iOS or share to open in VLC

9) Fix title tag to match mp3 filename for chapters with MusicBrainz Picard

10) Low volume m4b audiobook normalize the chapters using Audacity

11) Low volume m4b audiobook normalize each chapters audio using Ocenaudio

12) Automatically create chapters from a single mp3 audiobook

13) Manually create chapters from a single mp3 audiobook

14) Manually create chapters using timecodes with LosslessCut

15) Huge audiobook collections from various sources video / audio have various sample rates result in inaccurate chapter times

16) Edit chaptered opus audiobook chapter names or times with MusicBrainz Picard

17) automatically Human or Smart Title Case chapters and append : after chapter numbers

For advanced users you can convert an existing m4b chaptered audiobook with ffmpeg (5.x retains cover and 4.x doesn't)

ffmpeg -i input.m4b -vn -c:a libopus -b:a 16k output.opus

or just use videomass with this preset
-vn -c:a libopus -b:a 16k

Export WhatsApp stickers to Telegram on Android

From the Files app, scroll down to Internal storage, and tap on WhatsApp. Once you’re there, go to Media and then WhatsApp Stickers. Don’t be surprised if you find a large number of files in that folder—it holds your personal collection of stickers and every one you’ve ever received. Even the bad ones.Tap the three dots in the top right corner of your screen to Select all. If you want to trim the fat and grab only the best of the best, this is the perfect time to do so: choose the ones you want to export by long-pressing one file to activate selection mode, and then tapping on the rest. Once you’re done, hit the Share button (that “less than”-like symbol at the top of your screen). If you have a big collection—more than 500 stickers, for example—it’s possible that nothing will happen when you tap the Share button. Be patient—your phone’s just struggling with a heavy load.On the menu that pops from the bottom of the screen, choose Telegram, and then select the chat named Saved messages. This is a chat only you can see, and it will serve as your sticker bank. Unlike WhatsApp, Telegram doesn’t store your favorite stickers in a quick-access reservoir right beside the typing field, but you’ll be able to snatch them out of your Saved messages chat and forward them to any of your Telegram contacts. This also means you won’t have a quick way to save incoming stickers like you did on WhatsApp, so you’ll have to forward them from one chat to the other.
