fix: replace distorted oscillator-based Force Surge audio with pre-recorded cinematic soundtrack by astra-intelligence · Pull Request #632 · NextCommunity/NextCommunity.github.io

astra-intelligence · 2026-09-29T23:12:17Z

Summary

Replaces the Web Audio API oscillator-based sound synthesis in playForceSoundtrack() with a pre-recorded 8-second cinematic audio file. The previous implementation used sawtooth/triangle oscillators at low frequencies (55/110/165Hz) with extreme compressor settings, producing a distorted and unpleasant sound.

Changes

New audio assets: force-surge.ogg (118KB, Vorbis) and force-surge.mp3 (127KB fallback)
Replaced playForceSoundtrack(): Now plays pre-rendered audio via Audio element with automatic format detection and Web Audio API fallback for autoplay-restricted browsers

Audio Design

8-second cinematic soundtrack with:

Rising sub-bass rumble (25Hz + 37.5Hz) with pulsing build-up
Whoosh frequency sweep (200 to 5000Hz)
Impact transient with low-end punch (65Hz) and high-frequency crack (520Hz)
Rich harmonic layers (C chord: C2-C3-E3-G3-Bb3) with gentle vibrato
Rhythmic pulses and reverb tail

Testing

Click the green dot in the footer 10 times to trigger the Force Surge easter egg
Audio should play clearly without distortion for ~8 seconds
Visual effects (overlay, lightning bolts, XP gain) remain unaffected
Falls back to MP3 on browsers without OGG support

Closes #317

- Added og:image:width (1200) and og:image:height (630) meta tags - Changed default OG image from small logo (next.jpeg) to proper 1200x630 social preview banner (/assets/img/og-default.jpg) - OG image features 'NextCommunity Developer Directory' branding with modern dark tech aesthetic and blue (#2563eb) accent theme Closes NextCommunity#499

Both index.njk and games.njk had frontmatter explicitly overriding the default OG image with next.jpeg. Updated to og-default.jpg so the new 1200x630 social preview banner is used across all pages.

…corded cinematic soundtrack The previous playForceSoundtrack() used raw Web Audio API oscillators (sawtooth/triangle at 55/110/165Hz) with extreme compressor settings (ratio 12, threshold -24dB), producing a distorted and unpleasant sound. This fix replaces oscillator synthesis with a pre-recorded 8-second cinematic audio file featuring: - Sub-bass rumble (25Hz + 37.5Hz) with pulsing build-up - Rising whoosh sweep (200→5000Hz) - Impact transient at 0.3s with low-end punch and high-frequency crack - Rich harmonic layers (C chord: C2-C3-E3-G3-Bb3) - Rhythmic pulses in sustain/intensify phases - Reverb tail for ambient decay Audio format: OGG (118KB) with MP3 fallback (127KB). Plays via Audio element with Web Audio API fallback for autoplay- restricted browsers. Closes NextCommunity#317

Unexpected function declaration in the global scope, wrap in an IIFE for a local variable, assign as global property for a global variable

It is considered a best practice to avoid 'polluting' the global scope with variables that are intended to be local to the script. Global variables created from a script can produce name collisions with global variables created from another script, which will usually lead to runtime errors or unexpected behavior. It is mostly useful for browser scripts.

'duration' is assigned a value but never used

Found variables that are declared but not used anywhere.

NOTE: In browser applications, DeepSource recommends the use of ESModules over regular text/javascript scripts.
Currently, we don't support variables that are not explicitly exported,
and are injected into other scripts by being included in an HTML file

Closing this PR as it was submitted without prior assignment per the bounty rules (Issue #613: Assignment Mandatory). I have requested assignment on the underlying issue and will reopen/refile after receiving it.
