GPD Pocket 4 Speaker DSP: Configuring PipeWire so laptop speakers sound better
Configuring PipeWire to make laptop speakers sound better (Bankstown, Convolution/FIR, etc.)
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. Using Room EQ Wizard the frequency/impulse response of the built-in speakers was measured.Even with very suboptimal measurement equipment (cheap microphone, questionable audio interface), we can clearly see the sloped bass response (expected with speakers of this size) and then also a very noticeable peak/resonance at ~4kHz.This peak is very audible and leads to a harsh, distorted sound when listening to music. was stripped-down to just a single stereo pair and the parameters were changed a bit.The impulse response .wav was (of course) replaced with our newly generated REW output.
