You can still hear how the HRTF model is sampled only at 15° intervals. Perhaps I could interpolate.

Are complex or Real valued the bigger and small filters? Are you going to implement in FPGAs, GPUs or vía software? This sounds very complex and expensive in terms of resoucers and troughput.
-
Everything is real-valued for now and done in software. It's very CPU-intensive but it doesn't matter throughput-wise as it's an offline calculation (not real-time).

If their phase responses are perfectly aligned you should be able to linearly interpolate between the impulse responses without any problem. For example: Both IRs are symmetrical and of the same length. What do you mean by filtering the filter?
-
That would indeed be possible. I'm "filtering the filter" in the sense that I have a single-pole IIR low-pass filter for each coefficient, essentially a scalar multiplication and element-wise add of two float arrays.

how I solved that back in my http://M.Sc .-thesis days: FFT-based overlap-add / overlap-save filter with plenty overlap; you can even linearly interpolate between the different (freq-domain) filter realisations.
-
Thanks, that sounds clever. It would be faster anyway.
