As part of my PhD I am conducting large scale subjective testing of audio t= hat has been processed using different Time-Scale Modification algorithms, = and I would appreciate your assistance. To facilitate this I have used the= Web Audio Evaluation Tool to enable subjective testing through a browser, = and am conducting the research under Griffith University Ethics Reference 2= 018/671. The subjective testing can be found at http://www.timrobertssound.com.au/TS= M/index.html with each set taking approximately 10-15 minutes to complete. = You are able to complete as many or as few sets as you prefer. I currently have ~16600 ratings of files, with the goal to reach 25000. It= turns out that people know when audio sounds good and bad, but quality rat= ings vary quite a bit in the middle. I've added a plot of the current resp= onses to a reddit post requesting assistance. https://www.reddit.com/r/Samp= leSize/comments/b40q7w/repostacademic_rating_the_quality_of_time_scaled/ [https://preview.redd.it/6ck3htegmln21.png?overlay-align=3Dbottom,left&over= lay-pad=3D8,16&crop=3D1106:579.057591623,smart&overlay-height=3D0.10&overla= y=3D%2Fv9vyirk6hl221.png%3Fs%3Db466421949eb723078743745ce6421609d7a9c66&wid= th=3D1106&height=3D579.057591623&auto=3Dwebp&s=3Dba3d694a0a52c8260b65ba80e0= 94aee0bd6b98ed]<https://www.reddit.com/r/SampleSize/comments/b40q7w/reposta= cademic_rating_the_quality_of_time_scaled/> [Repost][Academic] Rating the quality of time scaled audio files (~10 minut= es)(Everyone)<https://www.reddit.com/r/SampleSize/comments/b40q7w/repostaca= demic_rating_the_quality_of_time_scaled/> www.reddit.com Posted in r/SampleSize by u/zygurt =95 1 point and 1 comment If you have any questions or suggestions please feel free to contact me.
