Easily the best Compressor

I have bought many compressors over the years. This one actually works well for anything. Awesome extra features like the mid scoop really help with sculpting sounds. And it’s relatively quiet compared to all the others.

Great addition to an audio toolbox.

The Red Rock CL1 is the most versatile analog style compressor for iPadOS devices. Unlike the very digital compressors that are very versatile the CL1 has character and nice saturation characteristics on top of the versatile compression. So if you are looking for a great all around compressor plugin grab this AUV3.

It’s wonderful but…

How do you save presets? Am I missing something?

Response from developer

Hi, this plug-in does not have its own preset saving feature; please use the DAW's (audio host's) preset saving functionality instead.

My fav AUv3 comp

Use this all the time, great on drums, master buss, anything really.
Can be subtle or destructive… I end up using this way more than my hardware 1176!

Unique Audio Texturing

The processing and filtering this app can produce in creating a textual audio plane. To me it is like the sound version of light, a photon and a wave. Or perhaps an oscilloscope plotting the captured points in time on a line to create a wave
