Test your hearing range! A series of pure sinewave test tones covering the audio spectrum from 20 Hz to 22 KHz, each preceded by a vocal announcement giving the frequency of the following tone. Tones created in Cool Edit Pro. PLEASE:- 1) Download the file, don't try the test using the Freesound preview. 2) You need a decent quality sound card/interface or you may well be hearing false sub-harmonics at the top end of the test.

    Please don't get me wrong, but this test is bound to fail. You're using an mp3 file with 128 kb/s encoding. That file format uses psycho-acoustics which means that you'll lose audio content. To make the test you need to have the file in lossless 32bit .wav format. The reason is that you get a whole lot more treble that way. This file loses treble over 14 kHz. And... Not even an external mp3 player with a decent soundcard can play this right. Sorry for the harsh words, nothing personal intended.
