Hey everyone, I am trying to import an audio snippet and use its corresponding frequency to move points in grasshopper and use the points to manipulate how a surface moves. I tried using firefly and it gets me close but i want the audio snippet to give me the same changing frequency that the frequency sampler in firefly gives.

Maybe this can give you some ideas: [image] Import a wav file into Grasshopper Grasshopper Hi! Is it possible, and how, to import a wave file, or mp3 in Grasshopper? I know that in Firefly there is the component “Sound Capture”, but it seems it is only from an input like a microphone. What i would like to do, is import my wave file. Is it possible? Thanks so much! slight_smile

Hey Peter, Thanks for your help. I really appreciate it. I came across this solution while I was looking into the problem a few days back but for some reason, my grasshopper doesn’t detect the right channel at all. I’ll attach a file for you to see. And while this solution does help me with half of my problem, i was looking into if i could get the left and right channel values as the changing numbers without them turning into a polyline. I just need the values so that I can constrain and remap it to feed into a data recorder and use that as a factor for my unit z component. [image]

[image] Swastika Regmi: doesn’t detect the right channel at all. Post the wav file in question (or rather a small indicative portion of it). All my tests back then were OK. In your case for some reason (damaged input?) the R channel is MIA (info panel tells you that). Update: did some (about 30) quick tests. Appears that in some wav files the R channel is MIA. Why? I have no idea. See 3 tests (the last has no R channel): [Screen Shot 040] [Screen Shot 041] [Screen Shot 042] For details see 1st C# (i.e. how it reads the file). [Screen Shot 043] BTW: It’s very easy to provide different - user controlled - outputs (Polylines as Graph used in order to visualise the whole thing).

Hey Peter, Sorry for the late reply but eventually the file worked out amazingly. I got what I needed. I just presented my project today and it went great. Thank you for all your help.
