SIR 2.4.009 Update (Macintosh only)

  • improved performance when merging two big files into a true stereo file

SIR 2.4.005 Update (Mac and Windows)

  • improved compatibility with fxpansion vst-rtas adapter (mac + windows)

SIR 2.4.002 Update (Windows only)

  • Setup in Windows Vista now automatically requires administrator rights, if UAC (User Account Control) is activated. This can prevent installation issues (dll can't be written in "Program Files" directory)

SIR 2.4.001 Update (Macintosh only)

  • compatibility issue fixed

SIR 2.4.000 Update

  • initial windows 64-bit release
  • triangle envelope functionality
  • finer Predelay adjustment
  • search functionality, if impulse file not found
  • ability to store EQ-presets (right mouse-click into EQ-Envelope)
  • improved project-portability between different workstations. (relative filename will be stored too, so if the default impulse-response location is different, the IR will be found) Please note: to use this function, the project has once to be saved with this new version.
  • support for "ctrl+mouse click", for one-button mouse macs

SIR 2.3.004 Update

  • minor fix (improves compatibility with wavelab)

SIR 2.3.003 Update (Macintosh only hotfix)

  • improves compatibility with fxpansion vst-rtas adapter (Mac)

SIR 2.3.001 Update

  • minor fix

SIR 2.3.0 Update

  • initial mac release
  • If you have two mono files, one with "L" and one with "R" at the end of the file name, you can click with right mouse button on one of these files to create a stereo file.
  • GUI now remembers that the time-line is in "Beat-Scale"-mode
  • When ever you convert a wav-file (or aif) to a sir-file, you will asked if you want to store it into the default impulse file directory or at the current location
  • fixed a cpu-glitch when play a loop in ableton live arrangement-view
  • internal convolution engine redesigned

SIR 2.2.0 Update

  • improved host compatibility
  • more routing capabilities ( mono->mono, mono->stereo etc.)
  • better support for mono-channels
  • auto true stereo file creation:

    If you have two stereo files, one with "L" and one with "R" at the end of the file name, you can click with right mouse button on one of the files to create a true stereo file. This is useful for special impulse response libraries.

    stereo/true stereo tree: If you have three stereo files, with L/R/C at the end of the file name, you can click with right mouse button on one of the files to create a stereo/true stereo tree, like the with SIR2 provided impulses. This is useful for special impulse response libraries.

SIR 2.1.0 Update

  • new impulse-file browser (with folders)
  • reset all parameters functionality in "Tools" menu
  • default impulse-file path can be changed in preferences
  • fixed some host compatibility issues (with wavelab & samplitude)
    Note: Due to several internal changes which were necessary to improve the host compatibility, the older release (2.0.0) isn't able to be used in projects, which already have been saved with the newer version (2.1.0)!
  • host sample rate change - volume compensation
    Due to the nature of convolution different sample-rates will produce different output levels. This function compensate this.
  • more detailed message when the impulse-file can't be located
  • new improved re-sampling algorithm (much better quality even in "low" mode)
    Note: If you want to use the old algorithm instead - select in preferences: Resampling Quality "compatibility (old) mode"
  • some minor fixes
