Hi Atom, would you mind showing how to draw the waveshape in the component using data from a MemoryBlock instead of a file? I’ve been trying to but can’t seem to figure out what to do instead of the loadFromFile call you use in the demo panel.
Anything from the AudioThumbnail class will work:
you can always check out the magic what() function in Lua to see what methods are available, in this case:

class): http://www.rawmaterialsoftware.com/juce/api/classAudioThumbnail.html
Sure that’s also possible, i’ll add that.
thanks a lot. If you get an example made it’d be great if you could send a link to a zip or something to save you some time instead of putting it in the new build, compiling the new build, uploading the new build, etc. but whatever works best for you.

The panel examples are always available from the SVN repository on sf.net, it’s public and anyone can download the latest version.
That should be there now, please use the latest nightly (i added some memory management so Ctrlr doesn’t leak it when using AudioFormatReaders)
I created a special placehold panel for all the DEMO panels with a link to the SVN repository: http://ctrlr.org/demo-panels/
Thanks for posting the demo, atom. I’ve got it nearly completely implemented. I’m using 48kHz .wav files, so the more or less standard waveform contains 1024 samples, which is easily devisable by 64. The waldorf microwaves only store/transmit 64 samples. Now i just need to grab every 16th sample to get to the zero crossing at the 513th sample and pass that on to my custom component.
I’m currently playing with the 8th line in the convert script to try and make some of the byte grabbing of the imported wave’s sampleData a little more manageable.
Just so you’re aware, the header of your “convert” script contains what I believe (hope!) is a typo:
convert = function(audioFromat) if audioFormat then console ("audioFormat is valid")Fromat 🙂

oh yeah it’s a type-o, it’s the name of the variable you can put “cock” in there and just reference “cock” inside the code, no problem.
right but if you put cock in there wont it get stuck if you call it occk later on?? like your code did?
Nothing actually was broke, just happened to see it was (audioFromat) then in the next line “audioFormat”, and the next line etc.

Question on this..
How do I get and assign every nth byte of the results of (sampleData:toHexString(1))
to variables I already have set?I’ve got:
WAVDSigned_XT_Sample01 = (sampleData:toHexString(1):getByte(1)) WAVDSigned_XT_Sample02 = (sampleData:toHexString(1):getByte(2)) WAVDSigned_XT_Sample03 = (sampleData:toHexString(1):getByte(3))Monstrum Media | Music, Sound & Software Design, Chicago / San Francisco listen
Well yes and no 🙂 it’s a type-o, if you put “cock” in
convert = function(cock)
then you just need to use that variable in the function, so replace audioFormat and audioFromat (if any) in the code with cock and it should work, it’s the same rule as with any other function argument.
I don’t remember if audioFormat wasn’t declare in a different lua method, and since ALL variables in Lua are global that might cause some issue. You can declare local only variables in Lua using the “local” keyword like so
convert = function(cock) local vagina = 1 -- vagina will be a local variable to this method, -- no other method will see it, so it will always -- evaluate to nil anywhere outside this method endmore details here for example: http://lua.gts-stolberg.de/en/Variablen.php in the section “Variables – Scope of application”
nevermind. `
WAVDSigned_XT_Sample01 = ((sampleData):getByte(1))
WAVDSigned_XT_Sample02 = ((sampleData):getByte(2))
WAVDSigned_XT_Sample03 = ((sampleData):getByte(3))
