Spatial and binaural audio with ffmpeg: headphone (HRTF binaural from multichannel), sofalizer (custom HRTF via SOFA files), surround (mono/stereo → 5.1/7.1 upmix), extrastereo, stereotools, stereowiden, earwax, crossfeed, channelsplit, channelmap, join. Use when the user asks to create binaural headphone audio, apply HRTF, convert stereo to 5.1, upmix mono to surround, widen stereo image, split channels to separate tracks, route channels, or fix mobile-device listening fatigue.
