A new resampler DSP for foobar2000

Good & fast resampler based on SoX resampling routines. (several times faster than PPHS Ultra).

0.8.3:
normal version: [attachment=7330:foo_dsp_...er_0.8.3.zip]modified: [attachment=7331:foo_dsp_...od_0.8.3.zip]and [attachment=7332:foo_dsp_...d2_0.8.3.zip]

Version 0.6.9:
  • Bugfix: error in initialization when CPU doesn't have SSE3.
Version 0.6.8:
  • Bugfix for new quality modes & multithreading
Version 0.6.6 have new quality modes:
  • Best -- the same as old 'Very high' mode
  • Good -- old 'Very high' mode but with single precision (instead of double precision in 'Best' mode)
  • Normal -- old 'High' mode with single precision
Version 0.6.0:
  • Uses SSE3 optimizations but also works on CPUs without SSE3 support (0.5.6 and 0.5.4.4 merged).
Version 0.5.6 (for CPU with SSE3 support):
  • Bugfix
  • Switched to MSVS 2010 + Intel compiler 12.0
Version 0.5.5:
  • SSE3 optimizations
Version 0.5.4.4 (for CPU without SSE3 support):
  • Bugfix: SSE2 instructions were enabled in 0.5.4.3, and plugin crashes on AthlonXP.
  • Optimized versions removed (use 0.5.5)
Version 0.5.4.3:
  • Minor UI changes.
  • Default settings are configurable in Advanced Preferences (reasmpling service now uses them).
  • Atom/Core 2/K8 optimized versions (compiled with MinGW32 4.5.0).
Version 0.5.4.2:
  • Recompiled with newer SDKs (foobar2000 1.0+ now required).
Version 0.5.4.1:
  • Added: Fast 4x upsampling.
Version 0.5.3:
  • Changed: Code cleanup.
Version 0.5.2:
  • Changed: Minor fixes and improvements.
Version 0.5.0:
  • Improved: New UI. Now it offers more control of passband and phase response.
  • Improved: New modes: "Upsample x2", "Downsample x2".
  • Improved: Now it uses resampler_entry class and WTL.
Version 0.4.0: was alpha only.

Version 0.3.2:
  • Fixed: memory leak was REALLY fixed.
Version 0.3.1:
  • Fixed: memory leak.
  • Added: "Low" quality setting.
Version 0.3.0a: plugin is just renamed to a shorter name. Nothing more, even plugin version number is still 0.3.0.

Version 0.3.0:
  • Fixed: resampling routines are changed to allow multiple instances of the plugin to work.
  • Fixed: incorrect flushing of audio stream when seeking
Version 0.2.1:
  • Fixed: bug in latency reporting
Version 0.2.0:
  • Initial public release

Modified version allows you to set a list of input frequencies that will pass through the plugin, unmodified. Or it can choose proper output frequency from the list.

*_mod: It doesn't resample the frequencies that you enter in the text field.

*_mod2: It resamples only the frequencies that you enter in the field.

Normal quality is enough for 16-bit precision output and is noticeably faster than Best.
Use Best mode if higher precision (24-bit, 32-bit float) is needed.

TWIMC: Speex SRC for foobar2000. I just took SoX resampler component and replaced SoX routines with Speex routines. Sources included.
(another implementation: http://www.hydrogenaudio.org/forums/index....howtopic=90322)

Update: Speex SRC with a few improvements from opus-tools project:
