+- Control delay in new AEC API.
+- NaN checks?
+- Better error reporting
+For 1.2:
+Major points:
+- Make documentation match the actual code (especially jitter buffer, AEC and preprocessor)
+- Get AGC to work in fixed-point even if not totally converted
+- Stabilise all APIs (need feedback)
+- Short-term estimate in jitter buffer
-Eventually:
+Minor issues:
+- Fix last frame of speexenc

+Post 1.2:
improve float<->int conversion

Optimisations
- Add restrict in a few places?
- enable 4x4 version of pitch_xcorr() at least on some archs?
+- use __builtin_expect() (likely()/unlikely())
Would be nice:
Implement wideband split as IIR instead of QMF?
