Change log:

• 2011-08-11- Version 0.9.2:
  
  • Fixed conversion crashes in SoundTouch based DSPs.
  • Increased frequency range of IIR DSP.
• 2011-06-21- Version 0.9.1:
  
  • Fixed crashes in rate/tempo DSPs.
• 2011-06-20- Version 0.9:
  
  • Added a rate modification DSP. Added finer grained control to the Pitch DSP.

  • Added tempo and pitch modification DSPs.
• 2011-02-10 - Version 0.7.1:
  • Fixed the realtime de-emphasis post processor to be on par with SoX. Made clear distinctions between the phono and CD de-emphasis filters in the IIR filter dialog. Many thanks to Sandrine for his testing.

  • Added allpass filters.
  • Added a new bandpass filter mode.
  • Added new IIR filter DSP to house the various IIR-related filter effects.
• 2010-12-14 - Version 0.4:
  • Added notch and high/low shelf filters
  • Increased range of parametric EQ
• 2010-12-13 - Version 0.3:
  • Added bandpass/resonant highpass/lowpass filters
  • Added a parametric EQ
• 2010-11-03 - Version 0.2:
  • Increased parameter ranges for Phaser and WahWah effects.
  • Truncated display values for Phaser and WahWah effects to 1 decimal place.
• Version 0.1:

Thank you very much for this useful plugin! I'm especially intrigued about the de-emphasis filter and that leads me to a question/request which may or may not be beyond the scope of your project:

A CD recorded with pre-emphasis (damn you, 80s!) has a special flag set to indicate this option. The CD flag can be seen in EAC and, if ripped correctly, is also indicated in the cuesheet (or could be added thusly). Now, I'm wondering if it would be possible to incorporate this flag detection mechanism either into your DSP plugin or make a dedicated plugin, much like the HDCD and DTS plugins, that would detect and pass the flag to foobar's title formatting functions and activate de-emphasis automatically accordingly.

And lastly (although I'm pretty sure you already know all this, but maybe it'll help others who jump aboard this train of thought) a link for further reading: http://wiki.hydrogenaudio.org/index.php?title=Pre-emphasis
