Red Rock Sound SA60 SPECTRUM ANALYSER v1.0.0 VST VST3 AU WiN macOS [FREE]

Red Rock Sound SA60 Spectrum Analyser is a real-time audio metering plugin that displays frequency content in one-third-octave bands. It gives hobby producers and mix engineers a visual reference for checking tonal balance alongside what they hear, whether working on individual tracks or a full mix.

The interface takes its cues from the classic DN60 analyser, introduced in 1980. Frequency-band readings are measured against an adjustable reference level in dB, with a scale beside the display for interpreting them. A separate scale on the right applies specifically to the overall level reading.

SA60 offers averaging and peak-reading modes, with indicators showing which is active. Three response settings—fast, medium and slow—let you choose how quickly the display follows changes in the audio. Left, Mid and Right display modes provide additional viewing options.

For everyday operation, double-clicking a control restores its default value, while holding Shift makes knob and fader adjustments finer. SA60 is a utility for producers who want straightforward spectrum monitoring rather than another sound-shaping effect.
