Cyberpunk

Audio Processing Server

Quick Start

docker run -p 8080:8080 -e PORT=8080 ghcr.io/jonaylor89/cyberpunk:main

Original audio:

https://raw.githubusercontent.com/jonaylor89/cyberpunk/main/testdata/celtic_pt2.mp3

Try out the following audio URLs:

http://localhost:8080/unsafe/https://raw.githubusercontent.com/jonaylor89/cyberpunk/main/testdata/celtic_pt2.mp3
http://localhost:8080/unsafe/https://raw.githubusercontent.com/jonaylor89/cyberpunk/main/testdata/celtic_pt2.mp3?reverse=true
http://localhost:8080/unsafe/https://raw.githubusercontent.com/jonaylor89/cyberpunk/main/testdata/celtic_pt2.mp3?slice=0:10000
http://localhost:8080/unsafe/https://raw.githubusercontent.com/jonaylor89/cyberpunk/main/testdata/celtic_pt2.mp3?reverse=true&repeat=1&slice=1000:5000

Cyberpunk Endpoint

Cyberpunk endpoint is a series of URL parts which defines the audio operations, followed by the audio URI:

/HASH|unsafe/AUDIO?slice&concat&fade_in&fade_out&repeat&reverse&filters=NAME(ARGS)

• HASH is the URL Signature hash, or unsafe if unsafe mode is used
• slice
• concat
• fade_in
• fade_out
• repeat
• reverse
• AUDIO is the audio URI

Cyberpunk provides utilities for previewing and generating Cyberpunk endpoint URI, including the cyberpunk_path function and the /params endpoint:

GET /params

Prepending /params to the existing endpoint returns the endpoint attributes in JSON form, useful for preview:

curl "http://localhost:8000/unsafe/celtic_p2.mp3?reverse=true&repeat=1&slice=1000:5000"

{
  "audio": "celtic_pt2.mp3",
  "hash": "unsafe",
  "reverse": true,
  "repeat": 1,
  "slice": {
      "start": 1000,
      "end": 5000,
  }
}
