Comp 609 AUv3 plug-in — comes as time-limited Demo-version for you to try. It gives you 5 minutes of Free play time. (You can reload the Comp 609 AUv3 plug-in as many times as you want, thereby you get the Demo period again and again.) Unlimited version of Comp 609 AUv3 plug-in comes as In-App Purchase. FEATURES: • 6 Attack, 9 Recovery (Release) and 5 Ratio selections; • External Sidechain and Sidechain signal High-pass filter; • 6 operation modes: M/S, Mid-channel, Side-channel, Mono with Right-channel as Sidechain signal, 2-Mono, linked Stereo (or Mono); • Parallel compression; • 8x Oversampling and 64-bit floating point processing; • Undo/Redo; • A/B comparison; • 2x/4x/8x Upsampling; • Macro controllers; • Built-in Gain Match; • Scalable GUI. COMPRESSOR SECTION: • Threshold determines how much compression will occur. When the input signal exceeds the Threshold level, the compressor engages. A smaller value results in more compression. The available range is from -20 dBu to +12 dBu; • Attack determines how fast limiting will engage when the signal exceeds the limiter Threshold. The available values is from 1 to 6; • Recovery (Release) is the time it takes for the compressor to stop processing after the signal drops below the Threshold value. The available values are 40, 80, 100, 400, 600, 800, 1000, 1500, 2000 ms; • Ratio — this control determines the compressor ratio. The available values are 1.5:1, 2:1, 3:1, 4:1 and 6:1; • Sat. On — this toggle switch enables the Analog Saturation. The saturation has no effect unless this switch is in the «On» (down) position. MASTER SECTION: • SC-Filter — the Sidechain Filter controls the cutoff frequency of a low-cut filter on the compressor control signal Sidechain. The available range is 30 Hz to 240 Hz and Off; • Input Gain controls the signal input level to the plug-in; • The Makeup control increases the signal level out of the compressor to compensate for reduced levels as a result of compression. The available range is -20 dB to +20 dB. The Makeup control does not affect the amount of compression; • Mix — the output balance between the signal processed by the plug-in and the original dry source signal can be adjusted with the Mix control. Mix facilitates parallel compression techniques without having to create additional routings in the DAW; • Comp. In — this toggle switch enables the compressor. The compressor has no effect unless this switch is in the «In» (down) position. • Mode — compressor can operate in six modes: M/S, Mid-channel, Side-channel, Mono with Right-channel as Sidechain signal, 2-Mono, linked Stereo (or Mono). This switch determines the active mode. To use Comp 609 as a plug-in, you need an AUv3-compatible host app like GarageBand, Auria, AUM, Cubasis and more — Comp 609 will appear in the list of Audio Unit extensions for effect plug-ins in the host app.

ToneBoosters GonioMeter is a one-stop stereo image analysis AUv3 plug-in. Easily identify stereo image imbalance or frequency ranges with negative correlation. Ensure that the content you create is of high quality and mono down-mix compatible, an essential requirement for mobile entertainment! The ToneBoosters GonioMeter stand-alone app captures the microphone input and processes the signals in real time. Since most iOS devices only have mono microphone capabilities, we strongly suggest to use the integrated AUv3 plug-in (app extension) version instead. To use it as a plug-in, use an AUv3-compatible host app such as Steinberg Cubasis, Apple Garageband, Audio Evolution Mobile Studio, Auria, AUM, or others. ToneBoosters GonioMeter will appear in the list of Audio Unit extensions for effect plug-ins. Key features: - Real-time goniometer to inspect stereo image waveforms - Real-time correlation meter and correlation spectrum meter - Real-time stereo balance an stereo balance spectrum meter - Color themes for the user interface - Max screen support in Garageband - Optimised for iPad and compatible with iPhone and iPod Touch What you should know: - Licenses acquired for this platform are not compatible with other platforms. - Audio Unit (AUv3) extensions require an iPad mini 2, iPad 4 or later models.

Verdict
The clearest difference is in-app purchases: TB GonioMeter at none against Comp 609's 1. TB GonioMeter also leads on update cadence (every 2 months vs every 7 months) and review sentiment (100% vs 88%). Comp 609's advantage is rating (4.8 vs 4.6) and iOS requirement (10.0 vs 13.0). On price, ratings volume, ads and device support there is nothing between them.

Written reviews complicate that: 88% of Comp 609's written reviews are positive against 100% of TB GonioMeter's, so the app with the better star average is not the one people write more warmly about.
Comp 609 ships an update every 7 months, TB GonioMeter every 2 months. The most recent releases landed on September 12, 2026 and September 8, 2026 respectively.
