Frequency weighting filters — time-domain SOS implementations with
.coefs(fs)for analysis.
| Package | What |
|---|---|
@audio/weighting-a |
IEC 61672 A-weighting |
@audio/weighting-b |
IEC 61672 / ANSI S1.42 B-weighting |
@audio/weighting-c |
IEC 61672 C-weighting |
@audio/weighting-d |
IEC 537 D-weighting (aircraft noise, resonant hump near 3.3 kHz) |
@audio/weighting-k |
ITU-R BS.1770-4 K-weighting (exact at any sample rate) |
@audio/weighting-itu468 |
ITU-R BS.468-4 noise weighting |
@audio/weighting-riaa |
RIAA playback equalization |
Each atom carries .response(f, fs) — the magnitude of its own SOS cascade, absorbed from the standalone a-weighting response functions. Extracted from filter.
