Max error is the 44.1 kHz bank against the 48 kHz bank.
How it was checked#
src/dsp/refit44.py compares each 44.1 kHz bank's computed response with the same file's 48 kHz bank on a 600-point grid from 20 Hz to 20 kHz.
What changed#
- Only the 44.1 kHz line of four VDCs changes.
- The 48 kHz bank, the section counts and the file format are untouched.
- The refit files were promoted into
src/profiles/in 6.1.0 after a listening check reported by the author.
