Bug#557563: audacity: Hi/Low Pass filters don't work

[Renato S. Yamane]

Package: audacity
Version: 1.3.9-6
Severity: normal

- Create a Pink Noise (Insert --> Noise);
- Apply a Hi-Pass filter (select all track and go to Effects --> Plugins 1-9 --> Hi-Pass Filter);
	6dB/octave works fine;
	12dB/octace don't works well. If you check with menu Analyser --> Frequency spectrum you will see a strange peak at cutoff frequency;
	24-36-48dB/octave don't work. If you apply it, will popup a messagebox with a "OK" button, but nothing will happening after click on it.

The same problem with low-pass filter.

Best regards,
Renato S. Yamane
