Mp3 playback on osx?
I'm developing an app that contains a 4.80 second musical groove that loops. When played in Pd with au or aiff files the groove accurately loops. When I convert au or aiff files to mp3"s, the length varies by .05 seconds and the loops are glitchy. The mp3's played back using quicktime are not exactly the same length as the au or aiff files from which they were compressed. How do I get the mp3's to be exactly the same length as the au/aiff files? Thanks
Mp3play~ lag?
I'm using [mp3play~] to trigger short samples. I've noticed that sending a stop message to kill the playback isn't too snappy. Noticeable delay.
So I was playing around with the pause message, because it's more immediate. But when I send a pause, then a stop, then re-open the mp3 file I'm trying to play and then re-start... it doesn't start at the beginning. It picks up where it left off.
I was thinking I could cut off the volume as an immediate stop, then sending the stop message to actually stop the thing. Or something of that nature.
Does anyone have any experience with [mp3play~] and it's quirks? Is there a message flow that works the best for rapidly playing and stopping mp3 clips? I'm currently sequencing small mp3 clips, so trigger lag isn't too much of an issue. But would it be feasible to have a live sampler that used mp3 files instead of wav?
Any help, thoughts, discussion appreciated.
Some of my PD tunes
These are some of my most recent tunes. These are purley PD.
I'm making some sort of microtonal/Xenharmonic synth or sound generator. haha!
These 3 have drum sounds I shamelessly borrowed from OBIWANNABE he done such a noce job at programming the drum sounds. Of course I came up with my own random trigger and delay pattern though. The synth sounds are from a homemade chaos fm feedback with sample and hold thing that I call the fmbrot.

This one has some distortion in it from alindx. I had the same idea for distortion when I was in college. clipping with diodes and averaging with the original signal via opamp. you can also briefly hear my karplus strong 12 string from about 2:00 to 2:38.

if you go to my http://sites.google.com/site/billystiltner you can hear more of my PD stuff. Most of the recent stuff was done with the assistance of PD acting as a pitchbend microtuner into Reason. My favorite of these is PHihr16.6 that you can only find on my youtube channel at this point. If you see a song that has draw in the name then it was done using the table draw thing from PD then there's my mandelbrot tunes which were done using only PD.
Then there's this one http://sites.google.com/site/pollypulsarsvisitingvertexes/PhimenGabbaFraca.PhiHr16.7.mp3 which was done using my mandelbrot melody generator (based on Elaine Walker's Chaos Melody Maker http://ziaspace.com read her thesis it's interesting) in PD synced / or started at the same time and BPM with drums I done in Reason. I thouroughly enjoyed this one it was good to hear that old amen drumbeat after a long break from the amen. hahaha!
Well have a good day and enjoy.

Streaming audio for free with Pd
I just wrote up a guide for streaming mp3 audio to a free Shoutcast host.

Didgeridoo into PureData live at Boise Experimental Music Festival
Here's my performance using Didgeridoo into PureData (using fiddle~ into some synths) live at Boise Experimental Music Festival:

here's another one:
Parabolic Beat Slasher.
I'll try get some video of this running on monday afternoon, but it will be camera phone quality.
This is a project i'm doing for uni, you can find a not very descriptive progress blog i'm doing as part of the project here http://shinyrobot.wordpress.com
The idea has evolved a long way since it started.
The sample playback borrows from something hardoff mentioned at some point. and the bass is butchered from obiwannabe(i'm horrible at synthesis, especially bass)
So anyway the project itself is a big dish that you roll golfballs in.
A camera tracks the golfballs in PD, and sends that data around to do different things.
It scribbles up the spiral, and it was originally drawing waveforms which modulated against each other.
It made these nice bubbly metallic sounds.
http://www.godinpants.com/sondes/bells.mp3
a bit scratchier and more hollow sounding when it was actually used though.
but after a lecturer suggested i make it sound less like max, i joked about a beatslicer because its something i like doing.
so i did it.
stutters/random jumps/flange type super delay are all picked randomly after being triggered by x and y being equal.
i should might add more triggers, it depends on how i like the ratio when used with the real dish(im just testing on my webcam at home waving around for now)
the bass pitch is being controlled by x and y added together and multiplied by 3, ending up with a range of 0-6
I'm talking a lot.
I'll chuck up a video in a few days.

This patch might glitch (the demo mp3 does a little), since I kept adding more CPU-intensive stuff until my computer could barely handle it. Also, it probably only works in Pd-extended, as it uses [sort] and the reverb patch from the extras.
There's a lot of stuff in there that I find handy to reuse for other patches, so go ahead and dissect it if you like it. I might post some abstractions of the more interesting individual modules.
Thanks to obiwannabe, from whose tutorials I copied a lot of stuff, and hardoff, whose analog distortion patch is in here.
Synthesis metal bars sound
HI,
i'm working on an installation based on this apllication made in java
i communique with pd via OSC
for each collision pd receive a bang with two parameters
height tube
position tube
i'm looking for synthesis metal bars sounds to transform this "thing" into a musical instrument
there is samples here

What kind of simple patch should i have to make for this goal?
au revoir
