[PD] Finding sample length of long aif
Greetings list, I'm developing an application for someone that involves picking a start and end point of a selection of long (30 minute) audio files. I've solved this by using [soundfile_info] to find the length. I provide two sets of arrays. One displays the waveform of a selection set from the beginning of the file. A second displays the waveform of a selection set from the end of the file. This works great for wave files, however [soundfile_info] doesn't work with aifs. Does anyone know of another method of getting the length (and preferably number of channels) of an aif?

Re: [PD] [PD-announce] new GUI obect: filterview, for generating and seeing biquad coefficients
Here are the steps I took: 1) I opened the help patch in the directory with the .pd_darwin binary file. 2) I turned on audio. 3) I selected a high pass filter. 4) I wondered if changing the bandwidth would do anything, so I moved my cursor over one of the red lines that show bandwidth. The line became highlighted but I could not move it from its position. 5) I selected a band pass filter. 6) I attempted to move the bandwidth, again, to no avail. 7) I single-clicked (no hold) in the area between the bandwidth markers and began changing the frequency of the band pass filter. 8) The filter continued following my pointer as long as it was inside the borders of the GUI. 9) If I moved my pointer out of the GUI and pressed command-E, the frequency would stop moving. 10) Pressing command-E, again, would resume following my pointer without my clicking anywhere. 11) Then, Pd failed with a spinning beach ball. A force quit was necessary. 12) In the meantime, when I clicked on the patch's titlebar, it showed one of the cursor symbols for changing the bandwidth. Let me know if I can help test it more.

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.

[PD] soundfiler is slow; readsf~ no filelength
How do I get the length of an aif file without using soundfiler? I've got an application that loads random aif and wav files from a chosen directory when triggered. I was using soundfiler to load a sound into an array where I could play it back with variable speed. When I ran two of these applications simultaneously, I noticed audio dropouts every time soundfiler would load a new sound. Soundfiler is not threaded, so I went looking for other people's solutions. Someone mentioned that Miller had suggested using readsf~ in an upsampled subpatch to read a sound into an array quickly. When you do this, how do you know how long to make your array to load in the sound? I suppose I could just make a preset length. I did see posts about wavinfo (buggy) and soundfile_info (only for wav files). Is there a way to get the sample length of aifs in Pd without soundfiler? This is an application I develop for someone else. It would not be appropriate for me to ask him to go through his entire collection of samples and change all the aifs to wavs. If I make the array an arbitrary length, he may be surprised when he starts trying to load in 2 minute files.

Katja, that sounds like a nice approach. With sound file playback, I could just delwrite~ the audio 3 seconds so everything would resync. I'm going to have to go back and look at fft, again. I spent a lot of time figuring out how to use [fft~] a few years ago. I'm not quite clear on how to tell what Hz value each bin is indicating. Wait, is it as simple as sample-rate/block-size=Hz?

The bin resolution is then ~0.37 Hz which may be just accurate enough for your purpose (spectral leakage will always make analysis less precise than the bin resolution suggests). Notice that the latency of your info will also be 3 seconds then.

The first thing I tried was a series of [lop~] and [hip~] filters in the ranges he was wanting. I stacked multiple [lop~]s and [hip~]s, to make really hard limits and then sent the output from each band to vu~ meters. This was unreliable. In fact, a 5 Hz sine wave seemed more likely to show up in the 10 Hz band. I also tried [bp~], [vcf~], and [svf~] with no luck. I then took a different approach, using [threshhold~] and [timer] to time the distance between zero crossings and output the result. This is very reliable for a sine wave, but I fear it wouldn't be that useful for real world signals. Have any of you ever tried to separate out subharmonic frequencies in Pd?

Re: [PD] gem -- antialiasing?
So, knowing about antialiasing is making me very excited. I just tried it on a MacBook Pro (Nvidia onboard graphics) in OS X. With FSAA 0, I had no antialiasing. WIth FSAA 1, I could see the jagged line effect reduced. With FSAA 2, I could see double the antialiasing effect. Past FSAA 4, I couldn't ascertain whether there was any difference. I'm wondering if this is documented anywhere. Also, I noted a huge drop in framerates when running antialiasing with a patch I made with seven regions of video feedback. I will have to try it later with the dedicated Nvidia graphics card running. I'm still wondering if it is possible to add blur to layers or create lens focus blur with Gem.

[PD] Pd 0.41.4-extended crash Mac OS X 10.5.8
I've been developing a custom modular synthesizer for a friend. However, he has been experiencing random crashes of Pd when trying to run it. We're both running Pd 0.41.4-extended on new Macbook Pros running 10.5.8. His is the 2009 17 Macbook Pro 2.8 GHz with 8 GB RAM. I've noticed it crashing on his computer when saving a patch, but not every time. I've seen it momentarily freeze when saving, too, and then not crash. There is a chance to crash at other times like when attempting to close a parent window or attempting to close the Pd window. Sometimes, Pd crashes and the GUI goes away but the other Pd process must be killed in Activity Monitor. Other times, it doesn't crash, but it won't let me close the project window, instead throwing the invalid command name error as seen below. Is anyone else noticing similar problems in OS 10.5.8 or on the new Mac hardware? Suggestions are appreciated.

Re: [PD] bug???!?!?
Ed, I have suspected [envrms~] of wrecking the performance of my patches before (on a PowerBook G4). I was never quite sure if it was really [envrms~]'s fault until I discovered [unsig~ #] and never went back. [unsig~] will do what [envrms~] does, but also allows you to set the sample time in milliseconds. I wonder if anyone else has had [envrms~] audio freezes.

Enclosed is a folder containing two versions of my clinoker~ drum synth. On one of them, the filter for the noise generator does not work, and on the other it does. The only difference between them is an [envrms~] measuring object on the frequency signal to the filter - but it's not even in the chain of signals that affects anything. Have a look. Ideas please?
