Designing Custom Plug-in For Your Own Online Radio

Designing a custom plugin for your own online radio depends on where the plugin will live (website, mobile app, DAW, streaming software) and what problem it solves.

Below is a no-fluff, practical blueprint you can actually build from—even solo and low budget.

1️⃣ First: Define the Plugin’s Role (Critical)

Before coding, lock this in:

What is your plugin supposed to do?

Common online radio plugin goals:
🎧 Live stream player (Play / Pause / Metadata)
🎙 Auto DJ / playlist scheduler
📡 Stream relay (Icecast / Shoutcast)
🎚 Audio processing (compressor, limiter, EQ)
📊 Listener analytics + ads triggers
🔔 Song request / live chat / donations
👉 Pick ONE core function first.

2️⃣ Choose Plugin Type (Most People Get This Wrong)

A) Website Plugin (FASTEST & CHEAPEST) ✅
Best if your radio lives on a website.
Tech stack
Frontend: HTML + CSS + JS
Audio: <audio> API or Howler.js
Backend (optional): Node.js / PHP
Stream: Icecast / Shoutcast

Use case
Embed player
Display “Now Playing”
Request song button

Ads trigger
✔ Easiest to launch
✔ No app store approval
✔ Works on desktop & mobile browser

B) Mobile App Plugin (Android / iOS)

RADIO GPT

If you want a radio app.
Options
Flutter plugin
React Native module
Native SDK (Java/Kotlin / Swift)
Use case
Background play
Push notifications

Lock screen controls
❌ More work
❌ App store rules

C) DAW Plugin (VST/AU) – Advanced 🚀

Only if you want broadcast audio processing.
Since you use REAPER, this might interest you.
Use JUCE Framework
Language: C++
Build VST3 / AU

Add limiter, EQ, loudness control
Output to streaming encoder
Use case:
Mastering chain for radio
Auto loudness normalization
Anti-clipping live broadcast

3️⃣ Core Architecture (Universal)
Copy code

[ Audio Source ]
     ↓
[ Encoder (MP3/AAC) ]
     ↓
[ Icecast/Shoutcast Server ]
     ↓
[ Plugin / Player ]
     ↓
[ Listener Device ]

Your plugin never hosts audio

👉 It controls, processes, or displays the stream.

4️⃣ Example: Build a Custom Web Radio Plugin (Practical)

Step 1: Streaming Server
Set up:
Icecast (free, open-source)
Encode via:
BUTT
OBS
Liquidsoap
REAPER → encoder

Step 2: Basic Player Plugin (HTML + JS)

Copy code
Html
<audio id="radio" src="https://yourstreamurl/stream" preload="none"></audio>

<button onclick="playRadio()">▶ Play</button>

<script>
function playRadio() {
  const radio = document.getElementById("radio");
  radio.play();
}
</script>
This is already a working plugin.

Step 3: Add “Now Playing” Metadata
Icecast exposes metadata:

Copy code

https://yourserver/status-json.xsl

Fetch it:
Copy code
Js
fetch("https://yourserver/status-json.xsl")
.then(res => res.json())
.then(data => {
  document.getElementById("nowplaying").innerText =
  data.icestats.source.title;
});

Step 4: Package as Plugin

Options:
WordPress Plugin
Embed JS widget
NPM package
Chrome extension

5️⃣ Monetization-Ready Features (Important)

Add logic, not just play button:
⏱ Ad trigger every X minutes
🎯 Geo-based ads
💸 “Donate” overlay
📈 Listener session tracking
🎵 Song request API

These features increase CPC & retention.

6️⃣ Tools You SHOULD Use (No Reinventing)
Purpose
Tool
Streaming
Icecast
Encoding
BUTT / Liquidsoap / REAPER
Audio FX
JUCE / ReaPlugs
Web Audio
Howler.js
Backend
Node.js / Firebase
Analytics
GA4 / Mixpanel

7️⃣ If You Want an AI-Driven Radio Plugin 🤖
Advanced but powerful:
Auto DJ using AI playlists
Auto loudness leveling
Voice cloning DJ
AI ad insertion based on listener behavior
This is high CPC territory.

8️⃣ Recommended Path (Based on Your Profile)
You are:
Music expert
REAPER user
Content monetizer
🔥 Best path:
Build Web Radio Plugin
Add AI Auto-DJ
Add Ad Trigger Logic
Later → Convert to mobile app

9️⃣ Next Step (I Can Build This With You)

If you want, tell me:

Website or app?
Icecast or Shoutcast?
Live DJ or Auto DJ?
Monetization goal (ads / donations / affiliate)

---------------

Below is a complete, end-to-end execution plan to build your own custom online radio plugin ecosystem (web + AI auto-DJ + monetization), optimized for solo builder, low budget, scalable to 100K+ listeners.

This is written as a build manual, not theory.

MASTER PLAN: CUSTOM ONLINE RADIO PLUGIN SYSTEM

PHASE 0 — FINAL GOAL (So We Don’t Drift)

You will own:

✅ A custom web radio player plugin

✅ AI Auto-DJ system

VIRTUAL DJ PRO

✅ Ad + monetization engine

✅ REAPER-based broadcast chain

✅ Expandable → mobile app later

PHASE 1 — INFRASTRUCTURE (FOUNDATION)

1️⃣ Streaming Server (Core)

Choose: Icecast (free, stable, scalable)

Server requirements

VPS (DigitalOcean / Vultr / Hetzner)

2GB RAM minimum

Ubuntu 22.04

Install Icecast

Copy code

Bash

sudo apt update

sudo apt install icecast2

Set:

Source password

Admin password

Mount point: /radio.mp3

2️⃣ Encoder Setup (REAPER → Icecast)

Since you already use REAPER, this is ideal.

REAPER Broadcast Chain

Copy code

[ Music / Mic ]

 → EQ

 → Compressor

 → Limiter (-1 dBTP)

 → Loudness target: -14 LUFS

 → Encoder (MP3 / AAC)

 → Icecast

Options

REAPER → BUTT

REAPER → ffmpeg

REAPER → ReaStream + Liquidsoap

🔥 Best: REAPER → BUTT (simplest, rock solid)

PHASE 2 — CUSTOM WEB RADIO PLUGIN (YOUR PRODUCT)

3️⃣ Plugin Architecture

Your plugin is a JS widget that can be embedded anywhere.

Copy code

radio-plugin/

 ├─ player.js

 ├─ ui.css

 ├─ config.json

 └─ index.html

4️⃣ Core Player Code (Minimal, Works Everywhere)

Copy code

Html

<audio id="radioPlayer" preload="none"></audio>

<button id="playBtn">▶ Play</button>

<div id="nowPlaying">Loading...</div>

Copy code

Js

const streamUrl = "https://yourserver:8000/radio.mp3";

const player = document.getElementById("radioPlayer");

const btn = document.getElementById("playBtn");

btn.onclick = () => {

  player.src = streamUrl;

  player.play();

};

5️⃣ Metadata (“Now Playing”)

Icecast endpoint:

Copy code

/status-json.xsl

Copy code

Js

setInterval(() => {

 fetch("https://yourserver/status-json.xsl")

  .then(res => res.json())

  .then(data => {

    document.getElementById("nowPlaying").innerText =

      data.icestats.source.title || "Live Radio";

  });

}, 5000);

6️⃣ Package as REAL Plugin

You now package this as:

✅ WordPress plugin

✅ Embed widget

✅ NPM package

This makes it sellable later.

PHASE 3 — AI AUTO-DJ SYSTEM (AUTOPILOT)

7️⃣ Auto-DJ Logic (Liquidsoap)

Liquidsoap handles:

Playlist rotation

Fallback music

Jingles

AI voice DJ

Install

Copy code

Bash

sudo apt install liquidsoap

Basic Script

Copy code

Liquidsoap

radio = playlist("/music")

output.icecast(%mp3, host="localhost", port=8000,

  password="hackme", mount="/radio.mp3", radio)

8️⃣ AI DJ Voice (Optional but Powerful)

Pipeline:

Copy code

Text Script

 → TTS (ElevenLabs / Coqui)

 → MP3

 → Liquidsoap inserts

AI DJ says:

Song intros

Time announcements

Sponsored messages

🔥 This boosts retention + ad CPM

PHASE 4 — MONETIZATION ENGINE 💰

9️⃣ Ad Trigger Logic

Inside plugin JS:

Copy code

Js

let playTime = 0;

setInterval(() => {

 playTime += 1;

 if (playTime === 900) showAd(); // every 15 min

}, 1000);

Ads can be:

Audio pre-roll

Banner

Affiliate CTA

Sponsored AI DJ message

🔟 High CPC Niches for Radio Ads

Target these formats:

AI tools

Crypto education (non-scam)

Finance apps

Online courses

Telegram bot

This creates viral loops.

PHASE 6 — FUTURE EXPANSION (OPTIONAL)

1️⃣4️⃣ Mobile App Conversion

Reuse same stream + logic:

React Native

Flutter

Add:

Background play
