SignalTrain LA2A Dataset

Colburn, Benjamin; Hawley, Scott

LA-2A Compressor data to accompany the paper "SignalTrain: Profiling Audio Compressors with Deep Neural Networks,"

Accompanying computer code:

A collection of recorded data from an analog Teletronix LA-2A opto-electronic compressor, for various settings of the Peak Reduction knob.  Other knobs were kept constant.  

Audio samples present in these files are either 'randomly generated', or downloaded audio clips with Create Commons licenses, or are property of Scott Hawley freely distributed as part of this dataset. 

Data taken by Ben Colburn, supervised by Scott Hawley


Revisions in v.1.1: 

Made the following corrections to discrepancies in original dataset:

Only one of file:  235, 236

  • $ rm Train/target_235_LA2A_2c__0__70.wav

  • $ rm Val/input_236_.wav

In wrong directory: 245

  • $ mv Train/input_245_.wav Val/

Mismatched length and time alignment: 148, 148, 149, 150, 152

  • All were had targets delayed by 8583 samples relative to inputs, and were shorter.

  • Truncated beginning of inputs to make them the same as targets. Used new script to fix & overwrite earlier version:

  • $ signaltrain/utils/ --fix SignalTrain_LA2A_Dataset/
