Red Rock Sound SA60 real time 1/3 octave Spectrum Analyser combines ease of use, accuracy and versatility in one economical, reliable unit. Interface is modelled on classic DN60 spectrum analyser, originally developed in 1980. Control & Indicator Functions: • DISPLAY LEVELS — Relate to the Reference level, calibration of a display level is read from graticules on the left of the display window; • REFERENCE LEVEL — The absolute level to which display readings are relative, i.e. calibration, is given in dB; • OVERALL LEVEL — Calibration of the overall level is similary derived from graticule to the right of the display. Note: this graticule applies to the overall level only! • AVG/PK — Two leds indicate whether the display is Averaging or Peak-reading; • RESP. — Speed of display response is selectable: «1» — Fast, «2» — Medium, «3» — Slow (shown by three leds); • MODE — Controls the display mode: «L» — Left, «M» — Mid, «R» — Right. EQ302 is a 32 band equaliser offering 12 dB of cut or boost in 1/3 octave steps between the frequencies of 16 Hz and 20 kHz. The graphic equaliser is a vital component in any audio system. The entire signal passes through it and so any limitations imposed by the equaliser will compromise the performance of the whole system. For example, an indifferently designed equaliser may introduce severe phase distortion, noise and other anomalies related to centre frequency accuracy, filter shape and attenuation accuracy which may manifest themselves as an overall deterioration in the perceived sound quality of the system. Clearly, this is an unacceptable state of affairs, but fortunately your choice to utilise a Red Rock Sound EQ302 Graphic Equalizer will eliminate these problems, offering you unprecedented product performance coupled with the highest filter calibration and reliability standards in the industry. To use SA60 as a plug-in, you need an AUv3-compatible host app like GarageBand, Auria, AUM, Cubasis and more — SA60 will appear in the list of Audio Unit extensions for effect plug-ins in the host app.

Verdict
The clearest difference is ads: SA60 at none against Met3D's shown. SA60 also leads on iOS requirement (10.0 vs 17.0). Met3D's advantage is update cadence (fortnightly vs every 5 months) and monetization model (free vs free with in-app purchases). On price, rating, ratings volume and in-app purchases there is nothing between them.
