The binary is working here on a MacIntosh 2.8 GHz Intel Core 2 Duo with OS 10.6.8. I thought you might appreciate some quick user feedback.</div><div><br></div><div>When I click the graphic, it lets me adjust frequency and amplitude, but then my cursor gets stuck to it like mouse up isn't working. Every time I click it adds another red vertical line.</div><div><br></div><div>A slight bit more documentation would be helpful in the help patch, too, explaining how one can interact with the graph with the mouse. Is it possible to change the bandwidth with the GUI? is there a key combination one can hold?</div><div><br></div><div>Sam</div><div><br></div><div><br></div><br><div><div>On Apr 8, 2012, at 2:55 , <a href="mailto:pd-list-request@iem.at">pd-list-request@iem.at</a> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; font-family: 'Calisto MT'; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; ">Message: 4<br>Date: Sun, 8 Apr 2012 12:50:05 -0400<br>From: Hans-Christoph Steiner <<a href="mailto:hans@at.or.at">hans@at.or.at</a>><br>Subject: Re: [PD] [PD-announce] new GUI obect: filterview,<span class="Apple-tab-span" style="white-space: pre; "> </span>for<br><span class="Apple-tab-span" style="white-space: pre; "> </span>generating and seeing biquad coefficients<br>To: Mike Moser-Booth <<a href="mailto:mmoserbooth@gmail.com">mmoserbooth@gmail.com</a>><br>Cc:<span class="Apple-converted-space"> </span><a href="mailto:pd-list@iem.at">pd-list@iem.at</a>, Marco Donnarumma <<a href="mailto:devel@thesaddj.com">devel@thesaddj.com</a>><br>Message-ID: <<a href="mailto:8BB69CDD-86CB-4455-8524-D2200A226CC1@at.or.at">8BB69CDD-86CB-4455-8524-D2200A226CC1@at.or.at</a>><br>Content-Type: text/plain; charset=us-ascii<br><br><br>Ok, big update, this should work a lot better.<br><br><a href="http://puredata.info/downloads/filterview">http://puredata.info/downloads/filterview</a><br><br>I changed the formula below to be a fixed resolution of 5 pixels. I was thinking that this should be generalized into a general biquad~ library, so with objects like [bandpass] to calculate biquad coefficients. The calculations could all be written in C as a shared library, then the Tcl code could use those C functions also, which I think would allow for 1 pixel resolution. My guess is that doing the math in C would make things noticeably faster.<br><br>.hc</span></blockquote></div><br></body></html>
