Stereo Tool

General purpose low delay preset. It's made for 75us so it might not take full advantage of the extra HF headroom that 50us offers when used in 50us. 77% quality is intentional. 100% sounds cleaner but also duller.
-Requires MPX clipper because otherwise it won't "sparkle".
-Uses multiband burst protection as a second multiband stage

For ST 7.60 (preset v7.1): You may want to set FM transmitter lowpass to 16400Hz or disable it (preset is already lowpasased at 16400). It make a difference in clarity for me.
For ST 7.60 (preset v7.1) 75us: Please uncheck Advanced Clipper > Distortion > Reduce IMD Voice Vibrations to improve transients and sibilants.

Could use more highs. I thought limiting the highs will reduce the artifacts but I don't seem to notice artifacts anymore so more highs it is. Should also sound clearer with 50us now.

7.1: enabled oversampled preclip for (marginally) better highs.

This version was made for ST 7.40. The mutiband behaviour has since changed and Sparkle v7.1 now sounds better on ST 7.50.

10.4: fix for new multiband behaviour
