Comment 2 for bug 57089

Good synthetic sample to test quality of resampling. If you hear noise after third tone the resampling is not so good as it can be.
It's need to have soundcard w/o 44100 Hz native support, like many Creative game cards or some integrated. If after "aplay -D hw:0 udial.wav" you get warning about 44100 and 48000 Hz - you card can't play 44.1kHz directly. But in this case you can hear as the sample must sounds (except it will sound a bit quicker and higher).
