Stereo Tool is available in a free and a registered version. The registered version is intended for commercial users of Stereo Tool, especially aimed at FM radio stations.
New in v5.00
Completely redesigned the processing Pipeline to reduce the maximum latency from over 1.5 seconds to at most 0.1 second, with a better sound quality.
# Made latency configurable in 4 Steps: 512 (ca. 13 ms), 1024 (25 ms), 2048 (47 ms) or 4096 (93 ms, best quality) samples.
# Reduced CPU usage by more than 50%.
# Replaced 3 quality modes (LO, MID, HI) by a continuous slider.
# Reduced memory usage by 17 MB.
# Replaced Pre Limiter by an RMS-based 1 or 2-band AGC, which controls the volume much better.
# Added a Bass Boost filter.
# Added Phase Rotation filter that greatly improves the sound quality of many difficult sounds (trumpets, female voices) when loud output levels are required.
# Added a filter that removes any pre-ringing (weird sounds before a sound burst) which was present in older Stereo Tool versions.
# Improved the Multiband clippers audio quality: Multiband clipping sound much cleaner now.
# Removed "Trumpet sound filter" from earlier versions that was intended to improve the quality of certain sounds, but also caused a lot of side effects (no longer needed due to the new phase rotation filter).
# Removed Multiband HQ mode (no longer needed).
# Made main window resizable and maximizable.
# Bug: No 2 Stereo Tool instances can be loaded in a VST engine based using the same Stereo Tool DLL file. A popup now displays this message and gives a workaround.
# Presets updated (now using Bass Boost and Phase Rotation where appropriate) or added.
# RDS without stereo no longer generates a 19 kHz pilot tone.
# In case of FM output, "normal output" is closer to the FM sound, and the FM sound is clipped better before 'FM Overdrive' - using FM Overdrive now leads to a 3% louder output signal than before with better quality.
# And more
