Bitrate Challenge Nr. 2 - Identifying Higher Bitrates

Bitrate Challenge Nr. 2!

Hey guys!

As consumers of digital music formats, we often get to choose the quality of the lossy file formats that make up the digital music libraries for so many of us. There are two general schools of thought regarding bitrates;

That higher bitrates makes for a better listening experience
That an increase in bitrate only creates a better listening experience up to a certain point (usually thought to be around 160~192 kbps)

The previous bitrate test (nr. 1) asked testers to rank a series of sound clips by in order of quality. This time, I've made it easier and divided the whole challenge into several simpler ones. You'll only have to choose between two options at a time. There are 6 tests pitching different bitrates against eachother and, with enough participants, the data can tell us something about what bitrates people are able to differentiate. So, please take a few minutes and do this test!

How to do it

Open the following site in your browser : Bitrate Challenge, Round 2!

The page contains 6 blind tests represented by 6 flash players. Each player plays two tracks. Underneath each player, you can tick off which one of the tracks you think has the highest quality. Tick it off and when you get to the bottom of the page, click the submit button. You'll get a short string of numbers, your choices, which you can paste to a post in this thread.

Good luck!

Edit :

Remember that the picks you get wrong are just as much worth as the ones you get right, so don't worry about that! Each individual result will not be made public, but you may get it on PM if you want.
