- Modern speakers use DSP to enhance sound quality.
- Traditional speakers required careful design for flat frequency response.
- Mobile devices use DSP tricks like psycho-acoustic bass enhancement and limiters.
- Asahi Linux project improves sound on Apple Silicon MacBooks running Linux.
- Frequency/impulse response measured using Room EQ Wizard.
- Identified a harsh peak at ~4kHz in the frequency response.
- Generated and applied a filter curve to correct the response.
- Used a convolution DSP filter with the corrected impulse response.
- Simplified MacBook Pro DSP setup for GPD Pocket 4.
