Stereo Tool

Stereo Tool 3.50 is now available on the download page!

The sound quality compared to 3.40 is a lot better, especially when using Loudness or when processing for FM transmitters.

Changes:

• Loudness filter: Recalibrated to achieve a much cleaner and louder sound. Distortion that was still present in version 3.40 is now nearly gone, and values up to 3.00 sound good.
  Values up to 4.00 are now allowed.
  Loud highs now have far less effect on the loudness of the other sounds - so it sounds much more stable.
  Added a filter to improve trumpet sounds.
  Improved quality and loudness of deep bass sounds.
• Improved FM pre-emphasis to match the official specification (in older versions the pre-emphasis wasn't strong enough, so this new version sounds brighter.)
• Volume slider now show both pre-emphasized and de-emphasized output levels.
• Changed Multiband compressor to get a warmer output sound with lower peak levels.
• Improved the HARD LIMIT filter to sound cleaner, cause far less pumping, and to achieve a louder output volume.
• Hard Limit filter is now also used if Direct Sound Card Output is used.
• Improved the composite limiter filter to cause far less pumping, and to achieve a louder and cleaner output volume.
• Updated presets, added FM Extreme preset.
• Improved Lowpass filter to filter closer to the selected lowpass frequency (important for AM presets).
  Also the filtering quality is now much better - the spectrum above the filtering frequency is now really empty.
• Bug fix: Fake stereo didn't work in version 3.40 - it does work again now.
  The CPU load is about 5-10% higher than that of version 3.40 - measured using the FM Loud preset.
