Stereo Tool

Stereo Tool is one of the most popular broadcast audio processors for FM and internet radio, and is our#1 top pick. It's available in several forms, including a VST plugin that brings world-class audio processingto Rocket Broadcaster.

Stereo Tool offers a comprehensive suite of effects that makes audio consistent, clear, and warm to listen to.It includes two multi-band compressors, stereo enhancement, bass enhancement, a fantastic graphical equalizer, automaticgain control, a noise gate, and much more. It also includes a unique 'declipper', which restores detail in recordingslost by tracks being recorded too loudly.

The free VST plugin version of Stereo Tool plays a short message ('This sound is processed by Stereo Tool') everycouple of hours, but this limitation can be removed by registering Stereo Tool for only €35.The registered version also unlocks the Advanced Clipper feature.

GranComp3 Free

GranComp3 is a relatively easy to use multiband compressor that helps smooth out theloudness of your broadcast. A multi-band compressor splits the bass, mid, and treble frequenciesof your audio, applies dynamic range compression to bring them all up the same volume level,and then mixes them back together. The result is a more balanced equalization, and usuallybrings out detail that can be lost while listening at lower volumes. (As a broadcaster, youwant to make sure your broadcast sounds good at any volume level, and on any set of speakers.)

To round out the package, GranComp3 also includes a peak limiter (to prevent clipping) and unique 'SonicFilters' that add saturation/character to your audio.

We recommend GranComp3 because it's free, and offers a simple set of presets for mastering. If you're new to VST plugins, compressors, or just want a quick way to enhance yourbroadcast's sound, this is a great plugin to try.
