GPD Pocket 4 Speaker DSP: Configuring PipeWire so laptop speakers sound better

GPD Pocket 4 Speaker DSP Configuring PipeWire to make laptop speakers sound better (Bankstown, Convolution/FIR, etc.) Result Motivation Modern speakers require a lot of DSP magic to sound as good as they do. Speakers traditionally needed to be built very carefully to achieve a very flat frequency response and as few artifacts as possible. These days, many mobile devices like phones, laptops, etc. do a lot of digital signal processing in software in order to make tiny speakers output a lot of sound. Many different tricks are used, such as psycho-acoustic bass enhancement, limiters (allowing for higher power peaks) and volume-dependent equalization (frequency response of human hearing is very volume-dependent). The Asahi Linux project (Linux on Apple Silicon MacBooks) has done a lot of work to make MacBooks sound as good as possible on Linux: AsahiLinux/asahi-audio: Userspace audio for Asahi Linux Using Room EQ Wizard the frequency/impulse response of the built-in speakers was ...
