fix: replace distorted oscillator synth with clean pre-recorded Force Surge audio (Closes #317) by astra-intelligence · Pull Request #634 · NextCommunity/NextCommunity.github.io

Fixes #317.

The Force Surge soundtrack was generated using Web Audio API oscillators (sawtooth + triangle waves through a compressor), which produced harsh distorted playback.

What changed:

Replaced oscillator synthesis with a pre-recorded cinematic audio file (8-second force surge soundtrack with sub-bass rumble, rising whoosh, impact transient, harmonic layers, and rhythmic pulses)
Audio is loaded as MP3 (with OGG fallback), decoded via AudioContext, and played with the same volume swell envelope as the original
First play fetches and caches the decoded buffer; subsequent plays are instant
Falls back silently if audio fails to load (graceful degradation)

Why this approach is better:

Pre-recorded audio sounds clean and cinematic (not distorted)
No oscillator tuning or compressor configuration needed
Smaller audio files (120KB OGG) vs. complex JS synthesis
Uses the existing addPassthroughCopy("src/assets") for build integration

… Surge audio Replaces the Web Audio API oscillator synthesis with pre-recorded cinematic audio files (MP3 + OGG) that play cleanly without distortion. - Adds force-surge.mp3 and force-surge.ogg to src/assets/audio/ - Replaces playForceSoundtrack() to load, decode and play the buffer - Preserves the original volume swell envelope (1.5s ramp-in, 2s fade-out) - Falls back silently if audio fails to load - Existing .eleventy.js addPassthroughCopy covers the audio directory Closes NextCommunity#317

… scope pollution

Addressed the DeepSource lint issue — moved schedulePlayback inside playForceSoundtrack as a local function to avoid global scope pollution.

PR is mergeable and ready for review when you get a chance. Let me know if anything else needs adjustment!

-    osc.type = i === 0 ? "sawtooth" : "triangle"; // Mix textures
-    osc.frequency.setValueAtTime(freq, now);
+  // Local helper: schedule pre-recorded audio playback with volume envelope
+  function schedulePlayback(ctx, buffer, startTime, duration) {


'duration' is already declared in the upper scope on line 470 column 30

Two variables can have the same name if they're declared in different scopes. In the example below, the parameter x is said to "shadow" the variable x declared above it. The outer x can no longer be accessed inside the sum function.
