This is a Heroku buildpack for using audiowaveform.
Originally based on Mattchewone/heroku-buildpack-audiowaveform.
Tested on the Heroku-20 stack.
We build and ship our own version of audiowaveform.
Heroku must have the dependencies required installed. We do this using heroku-buildpack-apt. The required dependencies are:
libmad0-dev
libid3tag0-dev
libsndfile1-dev
libgd-dev
Add them to Aptfile in the root of your application.
Build the binary inside the Docker image
docker build . -f Dockerfile -t audiowaveform-builder
Copy the built binary to /dist/
docker run -it -v (pwd)/dist/:/dist --rm audiowaveform-builder cp /build/audiowaveform-1.5.1/audiowaveform /dist/audiowaveform/bin/
Create an archive
cd build/
tar -zcvf audiowaveform.tar.gz audiowaveform
