# SuperchargeAudio 1.0.3 — Smoother Channel Switching and Consistent 8D Spatial Tone

> Two small fixes that clean up the feel of using the extension live. Flipping between channel modes or toggling 8D while audio is playing used to produce a brief click or pop; the gains now ramp the same way volume and EQ already do. The 8D spatial character is also deterministic now — pages with multiple videos, or a reload mid-session, no longer shift the "room" feel between clips. Everything else carries over from 1.0.2 unchanged.

## Highlights

- Switching between Stereo, Mono, and Wide modes no longer produces an audible click — gains ramp smoothly, the same way volume already did
- The 8D spatial effect now sounds the same every time — no more drift between clips or after a page reload

## Channel switching without the click

Flipping the Channel mode — Stereo, Mono, or Wide — used to cause a brief
audible pop if audio was already playing when you made the switch. The same
happened when toggling 8D on or off mid-playback. The pop was a byproduct of
the channel-mix gains jumping to their new values all at once.

Those gains now ramp over a short window rather than snapping. The transition
is inaudible — you hear the new mode settle in cleanly, the same way a volume
drag or EQ band adjustment already did. Nothing else about how the modes work
has changed.

## Consistent 8D character across clips and reloads

The 8D spatial effect builds its "room" — the reverb characteristics that give
the effect its depth — using parameters generated when the audio engine first
attaches to a media element. Before this release those parameters were
randomized on each attachment, which meant pages with several videos could
produce subtly different 8D characters per clip. A reload had the same effect:
the spatial feel could drift between sessions.

The parameters are now derived deterministically. The same page, the same
video, the same playback session — the 8D character stays consistent
throughout. If you switch a video, the effect sounds exactly as it did before.

## What carries over

No new permissions. No listing changes. The soft limiter, smooth volume and EQ
ramps, protected-stream capture banner, audible-tabs list, and the Chrome Web
Store listing from 1.0.2 are all here exactly as they were.
