This pull request introduces several improvements to the audio backend, focusing on more accurate and higher-quality audio processing, smoother transitions, and better volume control. The main changes include enhancements to volume application and normalization, improved resampler settings for higher audio fidelity, and more user-friendly volume adjustment behavior. **Audio Processing Improvements:** * Added fast paths for unity gain and mute in `apply_volume_static`, improving performance and precision when volume is unchanged or set to zero. Also, improved floating-point comparison in `apply_volume` to avoid infinite loops and ensure accurate volume ramping.
