Ok, self-oscillation is another issue, English isn't my native language. I also struggled with the English language when I tried to explain why a shelving filter, wich starts at a give frequency, could be considered a shelving filter to both sides of the frequencies, with an imaginary center frequency. Fons found the correct words, but they don't explain it that easy, as I tried to explain it. -- ubuntu-studio-devel mailing list ubuntu-studio-devel@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel
