OK guys this is the first in a possible series of hearing tests I want you to take [img]images/icons/wink.gif[/img] With all the debate on how crappy MP3\'s are etc. I want to put it to the test. There is only one rule in this \"competition\": You may only use your hearing. No spectrum analyzing or other tricks. I know I won\'t be able to lurk on you and see if you\'re actually resorting to that dirty trick, so I\'ll just ask you kindly not to. If not, the next test will be done using the LAME codec which has a setting which makes it much harder to reveal any changes to the waveform in an analyzer.
OK I have chosen a short piece of John Williams from Jurassic Park that you\'re probably not too familiar with. It\'s from an action sequence so it has quite a lot of dynamics and the whole CD has a very bright sound to it.
You can download the file here:
http://www.simonravn.com/media/16bit-testV1.rar - it\'s a 12MB download!
The file includes 4 .WAV files.
- One is the original .WAV file ripped from the CD.
- One is 192kbps MP3
- One is 320kbps MP3
- One is variable bit rate MP3.
Feel free to write me a private email at email@example.com with your \"votes\" on which file is which.
This is not the toughest example I found out - I will make it harder the next time... [img]images/icons/smile.gif[/img]
