Trashcompactor Build with characterization plots

[dbeasley]

Hello everyone! I build the Trash Compactor compressor awhile back, it sounds great. I had some time to measure it's characterizations on my Audio Precision APx555 and thought I would share some raw data.

Here is a Frequency response plot:



Here is max input level before clip:



THD+N vs Amplitude:



Input control sweep (I made my input trim control an external pot)



Compression Curves across 9 positions of the COMP knob



FFT of the output with COMP control at noon:



Attack and Release Times:



Input to Output Phase relationship - Note that the effect does invert the phase of the signal going in:



Overall I really like this comp.

Might have to build me a trash compactor now
