Analogue Recording/Reproducing TRIZ Cases
- Frequency-Warped Audio Equalizer for Accurate Low-Cost Filtering
Frequency warping improves equalizer band isolation, delivering FIR-like accuracy with lower computing load than conventional filters.
- Segment-Based Audio Equalization for Dynamic Sound Field Expansion
Audio is split into segments and equalizer settings are adapted from extracted features to enlarge the sound field without manual tuning.
- Frequency-Warped Audio Equalizer for Precise Band Isolation
Frequency warping improves equalizer accuracy and band isolation while avoiding the high compute cost of FIR filtering.
