Metallic ReadMe
---------------

This folder contains the results from a Tonmeister undergraduate technical project that evaluated the metallic-nature of stimuli.

The contents of this directory are as follows.

ListeningTestResults.csv
 - Raw results from a listening test where subjects rated stimuli as:
   (1) not sounding metallic; 
   (2) possibly sounding metallic (unsure); or
   (3) sounding metallic.
 - Results are arranged by test page (T1 to T10) and (within each test page) stimulus number (1 to 8).  

Stimuli
 - Audio stimuli used in the listening test.  Each subfolder represents a separate test page on the listening test. Sounds were sourced from the Open Path Music Custom Sample Library, the Berklee College of Music Sampling Archive, and a personal existing collection of samples.

ResultsArranged.csv
 - Listening test results arranged to enable a logistic regression model to be developed.  The columns within this file are:
   Column 1 - the raw results (from Column 2) reduced to a binary decision, where a value of 1 is given if the response was that the stimulus sounded metallic, and a value of zero is given if listener was unsure or considered the stimulus to not sound metallic.  
   Column 2 - the raw results for each subject.  
   Column 3 - the subject number.
   Column 4 - the trial number, relating to a set of stimuli from within the Stimuli folder.
   Column 5 - the stimulus number, with reference to ListeningTestResults.
   Column 6 - the stimulus ID, which is a unique number given to each stimulus. 
   Column 7 - the stimulus name.
   Column 8 - the audio file name.
 - It is this ResultsArranged file that was used for training the logistic regression model.
