Thanks for putting efforts into this application, much appreciated!

Some more specific feedback was asked for so I did some testing on my N9. I chosed Tiny Dancer with Elton John Greatest Hits available in the db. I played the song from my laptop in front of me. I tried both with holding the phone in my hand approx 20 cm from the computer speaker and also by putting it on the table approx 15-20 cm from the speaker. I couldn't notice any difference. I also tried to lower the volume on the pc but couldn't find any differencies there either. Eyrie either found the song or not at the same places in the song. I tried this several times for the timings below and was almost the same result every time. It could take longer some times to find it but it could be due to my timing starting Eyrie.

The results below is first when I started Eyrie in the song. Second when Eyrie reports a result and third if it found it or not.

00:00 - 00:15 - Found it
00;24 - 00:58 - Found it
01:00 - 01:25 - Found it
01:30 - 01:55 - Found it
02:00 - 02:25 - Found it
02:30 - 03:18 - Didn't find it
03:00 - 03:45 - Didn't find it
04:00 - 04:49 - Didn't find it
05:15 - 06:02 - Didn't find it

I also tried to play this song on the phone and it had no problem finding it in the first part as when trying with OTA. I noticed that the frequency waves are not visible when playing from phone. Maybe a good reason for this.
