aws-exec VS m4b-tool

cloud is so good now it’s hard to justify not doing something bespoke. ec2 spot is insanely cheaper than turnkey cicd, and better in almost every way.

i’m delighted to pay 30% over infra cost for convenience, but not 500%. and it better actually be convenient, not just have a good landing page and sales team.

this month i learned localzones have even better spot prices. losangeles-1 is half the spot price of us-west-2.

for a runner, do something like this, but react to an http call instead of a s3 put[1].

for a web ui do something like this[2].

s3, lambda, and ec2 spot are a perfect fit for cicd and a lot more.

on aws as scale to zero services. lambda, dynamo, s3, and ephemeral ec2 spot.

when egress bandwidth is needed i use cloudflare workers + r2 just like i would use s3 presigned urls.

typically i start from a full project template[1][2]. sometimes i start from scratch[3].

I’ve been using https://github.com/sandreas/m4b-tool for years to combine files into m4b, add cover and metadata. I also use iOS and prologue for listening.

MP3Merge, m4b-tool. This one is interesting for iOS users.

Look into m4btool (https://github.com/sandreas/m4b-tool). Audiobookbinder increases the m4b filesize. Followed this post for my own purposes: https://apple.stackexchange.com/questions/426094/convert-multiple-mp3-files-or-single-m4a-into-m4b-with-ffmpeg-and-afconvert

M4B-tool which wraps ffmpeg might be your best bet if you are planning on converting m4b’s.
