feat: add Audio Gain block with live property updates#464
Merged
Conversation
Add a simple serial audio processing block for inline gain, mute, and polarity inversion. Uses GStreamer volume element for gain/mute and audioamplify for polarity inversion (amplification=-1.0). All properties are stored in user-friendly units (dB for gain, bool for invert) and converted to GStreamer's internal format (linear, amplification) both at build time and during runtime property updates. This is the first block with live-updating properties in the right-side properties panel. Properties show a green LIVE badge with hover tooltip explaining the real-time behavior. The reset button also triggers live updates to ensure the pipeline stays in sync. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Add a `live: bool` field to ExposedProperty in strom-types so any block can mark individual properties as real-time updatable. The frontend now checks `exposed_prop.live` instead of hardcoding block IDs to determine which properties show LIVE badges and send direct pipeline updates. Also replaces audioinvert with audioamplify (amplification=-1.0) for polarity inversion, and fixes the reset button to trigger live updates.

… type mismatch Fix inconsistent indentation of `live: false` across block definitions, change audiogain amplification type from f32 to f64 for consistency with PropertyValue::Float, add 80ms debounce on live property API calls to prevent flooding during slider drags, and fix misplaced doc comments.
