Hi Gabe !

Glad to hear interest towards sonification : )

My understanding of your question is that you are asking if you can define a function in Csound to sonify data - is that correct ?

I am interested in the answer to this question, having done some sonifications in the last years, but I have no answer since I never used Python functions in Csound directly - usually what I do is to use Python to generate Csound partitions, that I then copy-paste into a .csd file, as demonstrated here: https://github.com/eviau/datasonification

I can see a few technical matters that might come up with large amount of data - such as figuring out the min/max values of the serie at hands... ? I am not so technical as to offer advice here, I hope there will be interest in this question.

Hello everyone,
Before committing to this project, I would like to ask for your opinion
on its real feasibility.
Below, I present my idea and ask if, based on your experience, this can
be implemented using Csound.
I want to create a Python function, to later import into my projects,
which performs the task described below.


def sonify(data_list, duration, lower_note="C2", upper_note="C8",
wave_form="sine", ptm=False, vol=0.5):

     '''
     sonify V6.0 Alpha, Jan 7th, 2025
     It sonifies a series of float data
     RX: a float list with values between 5 and 500k
         duration in ms
         lower and upper note define a note range to scale the values in
         wave_form determines the type of wave to play
         bool ptm: portamento, if true, a glissando will be applied
between value transitions
     It returns nothing but audio
     '''
This is very important for understanding the trend of a series of
numerical data if you cannot see the graphs.
What do you think? Can it be done with Csound?
I have already tried with pyo, obtaining subpar results, probably due to
my limited skills with that library. Particularly when the data to be
sonified was large, the results were disappointing. Then I tried again
with sounddevice, improving the outcome but still experiencing some
imprecision.
Now I would like to challenge myself with Csound.
Thank you very much in advance for your opinion.
Gabe
