Major update to ADPCM-XQ with many new features and performance gains:
- Added non-standard 2-bit, 3-bit, and 5-bit IMA ADPCM options
- Greatly improved encoding speed for high depth lookahead
- Increased command-line maximum search depth from 8 to 16
- Added option (-x) for old "exhaustive" searches (very slow)
- Added option (-n) to calculate encode quantization noise
- New improved dynamic noise shaping (DNS) algorithm from WavPack
- New option (-s) to enable fixed noise shaping and set slope
- Essentially backward-compatible library API
Windows and Mac binaries attached. Thanks to @gingerbeardman for the Mac build!
