DigitalFeed
DigitalFeed runs an online ABX test comparing lossless and lossy music samples using a browser audio interface.
About DigitalFeed
DigitalFeed hosts a browser-based ABX test that compares lossless and lossy music samples, based on a test by the streaming service Tidal. Listeners switch between the two versions of a sample and indicate which they believe is which.
The test requires a browser that supports the Web Audio APIs; Internet Explorer cannot run it. After a run, the site presents a p-value, described as the likelihood that the result would occur by chance if there were no difference, and reports when the listener distinguished the lossy and lossless samples. No pricing details are listed.
