Hi forum~,

I would like to save different data to a kind of data structure (it is the result of analyzing a sound file (with bonk~ and fiddle~):

• float velocity
• float frequency
• string (or symbol?) filename

These three values should be stored in an array or something like that. Later there should be added more values for other songs.

I would like to store that into a file to have like a directory of the values of analyzed songs. After that I want to play songs choosing them based on their velocity and frequency (the stored data).

I'm a newbie and all documentation about arrays (table) and data structures (struct) are pretty difficult to understand. If you could provide me a good tutorial, it'd help me a lot.

Some help would be nice!
Thanks,
Michael

look for array in the tutorials..

there is explained how to save values into text files

sorry for asking stupid questions! I found out how to write and save arrays to a txt-file. But after 2 days of doing research in the web and the pd tutorials I couldn't find any solution for my issue.

I understood that arrays are for saving the curve of a sound. I still don't understand how to fill the array with flexibly data.

Let me explain how I would like to use the array.

array[int index][0] - integer with value of velocity
array[int index][1] - integer with value of frequency
array[int index][2] - string with filename

with:
array[0][] - song1.wav
array[1][] - song2.wav

later on I want to do a "nearest neighbor search" on the array. to play a suitable song.

Please help me! You'd help me a lot.

Ah, Pd isn't really good at structured data like that. Personally I'd use a scripting external for Pd, like pyext or pdlua.

Thank you Claudius Maximus!

I did it with the py/pyext and it works. Event tough it was a tuff job, cause py/pyext and pd crashed very often on my OS X 10.5.2.
I haven't programmed python untill now. anyway the examples of pyext (in the folder) are pretty cool.
