Audio Processing Server
Project description
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:8000/unsafe/https://raw.githubusercontent.com/jonaylor89/cyberpunk/main/testdata/celtic_pt2.mp3
http://localhost:8000/unsafe/https://raw.githubusercontent.com/jonaylor89/cyberpunk/main/testdata/celtic_pt2.mp3?reverse=true
http://localhost:8000/unsafe/https://raw.githubusercontent.com/jonaylor89/cyberpunk/main/testdata/celtic_pt2.mp3?slice=0:10000
http://localhost:8000/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, orunsafe
if unsafe mode is usedslice
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,
}
}
