The mappings you added are obviously useful, especially for milliseconds (x^3)
mappings, but these are *not logscale*. A true logscale mapping plots as line

**Short answer:**
I spent some time debugging it, -mfma is causing this - removing
Relax expected accuracy for 24-bit subsampling from 126 to 124.5 dB, to fix

I cleaned up the resampling code:
* the C API was removed
* the implementation no longer relies on blockutils, but does its own SSE/FPU
handling
* Resampler2::create() got an additional argument: true means SSE should be
used if available; false means the FPU version should always be used

Inserting T=float casts makes the function perform better (at least here). It

First of all, this adds a function that was missing in bsemathsignal: a

approximating the rest of the value using a polynomial. I found a tool that

This is a fix for #119 - and finally should make beast work out of the box for

Currently, if you want to return a Resampler2 object to its initial state (all
