ChoreoBuilder

This post is being updated as I work on ChoreoBuilder.

Why?

When I was living in Japan, I was given precious opportunities to perform in festivals and community events in the town I was living in.^1.. Whenever I create a choreography for a tune, I split the audio in parts and write notes on my iPad on what moves or transitions I can do. My motivation with ChoreoBuilder was to streamline this process.

Uploading a Choreography

Initially, the main idea of this app is

• Getting audio files from your Files to create separate parts with them
• Copying files to your sandbox.

Models

Simply enough, every routine has parts and every parts have moves of different movetypes.

Playing with AVAudioPlayer

AudioPlayerModel

Every part comes

//PartView
if let partURL = part.location {
        AudioPlayerView(audioFileURL: partURL, partTitle: part.title)
    }

Controls

Functions I had learn how to implement:

1. play
2. seek forwards and backwords
3. loop
4. custom loop
5. delay
6. speedRate

Custom Slider

What to build

Much of the functionality I’ve implemented was based on the VLC iOS app.

1. Custom Loop: Allowing the perfomer to practice a specific section inside the part
2. Delay: For a part, we want the performer to be able to have their own countdown

Things I learned

1. DropViewDelegate inside a Scrollview
2. Building a custom expandable AudioPlayer

Footnotes

1. For reference, I juggle and dance to tunes I learn. For example, what I like to do is learn a song on piano and then build a dance/juggling choreography with it.

2. I use choreography and routine interchangeably.
