Audio Improvements

Mono audio options

• stops sounds from being affected by the direction you're looking in while still becoming quieter when further away
• options for different categories: jukeboxes, note blocks, weather, blocks, hostile mobs, neutral mobs, players, ambience/environment
  (only mono jukeboxes and note blocks enabled by default)

Logarithmic volume sliders

(enabled by default)
Makes the scale of vanilla volume sliders better match the human volume perception

Inspired by Logarithmic Volume Control mod

Music clash prevention

• fades out the regular game music while a music block is playing near you
• toggleable seperately for jukeboxes and note blocks (both enabled by default)
• customizable fade in/out durations

Music repeat prevention

(enabled by default)
Prevents the same music piece from playing multiple times in a row

Custom music frequency

(disabled by default)

• replaces the vanilla music frequencies with a customizable random interval
• has a setting for whether this should also affect the main menu music

Music disc distance multiplier

50% - 300% or global (100% by default)

Speed of sound simulation

• delays sounds based on how far their source is from you
• options:
  • Thunder sounds (100 blocks/second by default)
  • Explosion sounds (100 blocks/second by default)
  • All other sounds (disabled by default)

Doppler effect

(disabled by default)

• pitches sounds up/down depending on how fast the distance between you and them changes
• doesn't work on mono sounds due to sound engine limitations

Stereo spatialization fix

(disabled by default)
Fixes resource pack and mod audio that incorrectly uses stereo files for in-world sounds by converting them to mono, so the sound engine can then correctly position it instead of always playing directly at the listener

[pre 1.21.9] Fix for vanilla bug MC-98200

(= sound category volume sliders not affecting the volume of certain sounds at higher percentages - e.g. music discs already reached 100% volume at 25% slider value)
