EDIT: I added support for eqAPO and autoEQ.
When you use REW on a MAC, an easy way to apply the generated EQ is provided by Apple: AUNBandEQ is a plugin implementing IIR filters.
REW created an output for AUNBandEQ with frequency/gain/width for each filter.
I usually manually copy each data (3 per filters, up to 16 filters) to the plugin. This is error prone and boring.
I created a small script that takes the eq file generated by REW and generates a AUpreset (a configuration file for the plugin). You then only need to drop the AUpreset file on top of the plugin window and magic, all parameters are set.
Apple is not very transparent on how the AUpreset file is generated. After some reverse engineering, I have found a likely mapping of the data. I do not guaranty that it will always works and/or that Apple will not change the format over time.
This is an alpha version but it can convert
into
The data field is not very well documented, my guesses are:
- uuencoded block
- data is bigendian, 4 bytes for each parameters, parameters comes in pair (key, value)
- first 5 are
- 0
- 0
- number of parameters +1 (uint32)
- 0
- gain (float)
- then 80 parameters (16 eq with 5 parameters each): details
Ideally this would be implemented directly in REW (@JohnPM).
