M4Baker bakes mp3 files to Audiobook format (m4b).

I am building it with my personal wishes and needs in mind as I am the developer and the main user :-) The design is with ease of use in mind.

• Mandatory fields
  • Title
  • Artist
  • Cover Art
  • MP3 files
• When at least the mandatory fields are filled the "Queue" button will become available
• When Queued processing of the project will begin, and the current project windows will be cleaned to start a new one.
• The progress of all queued projects can be seen on the Queue tab.
• In theory, you can Queue as many projects as you want, depending on the capacity of your machine.
• Processes that are stopped (x) or have failed for some reason will show in red
• Successfully completed projects will show up green.
• A stopped process can be removed from the queue by using the (x) in the entry.

Projects can be saved to files called *.m4baker and reopened through the app or recent history. I want to associate the files to the app but don't know how yet.

• Binary downloads for macOS are available here: https://m4baker.ivonet.nl/index.html
• Please read this blog about Open "Unidentified Developer" Apps On Your Mac
• The application is very much in development mode and has only been tested on my machine. Feedback is appreciated twitter @ivonet.

• If you like this software and think I deserve a nice cold beer, or a good cup of coffee you can consider buying me a coffee donation.
• Just showing your appreciation on Twitter is almost just as nice!

• Python 3.9 (brew install python)

To be placed in src/resources:

• ffmpeg & ffprobe
  • https://github.com/descriptinc/ffmpeg-ffprobe-static/releases
  • https://evermeet.cx/ffmpeg/
  • https://osxexperts.net/
• mp4chaps (brew install mp4v2)
• mp4art (brew install mp4v2)
• AtomicParsley (brew install AtomicParsley) or binary)
• mp3binder (build from source: https://github.com/crra/mp3binder)

how...

#cp -vf "$(which ffmpeg)" "./src/resources"
#cp -vf "$(which ffprobe)" "./src/resources"
cp -vf "$(which mp4chaps)" "./src/resources"
cp -vf "$(which mp4art)" "./src/resources"
cp -vf "$(which AtomicParsley)" "./src/resources"

Not yet sure if I need them all but will adjust as needed :-)

To create and activate the environment

python3.9 -m venv venv
source venv/bin/activate
pip install poetry 
# Because wxPython did not install I needed to add these two exports
export CFLAGS=-I/$(brew --prefix)/include
export CXXFLAGS=-I/$(brew --prefix)/include
poetry install

I had some trouble getting it to work on the Apple M1 chipset and for that added the two export lines.

cd PROJECT
source venv/bin/activate
python src/m4baker.py

# or

DEBUG=True python src/m4baker.py # Will show extra debug logging in the log window

This can help identify problems when normal logging is not enough.

DEBUG=True open /Applications/M4Baker.app

source venv/bin/activate
./build.sh [clean]

The clean option will first remove the build and dist folder before rendering all the images to the ivonet/image/images.py file and building the application

See also the build.sh script

./images.sh

This script will convert all the ./images/*.{bmp,png} images to a format easily understood by wxPython.

If you want to collaborate on this project to improve it or give in more functionality please drop me a PM on twitter @ivonet
