I had so much fun with this one. Originally I planned to make a short sound file, kind of like a small musical piece (techno music) but when I came across a frog-like sound I decided to make an audio file that sounded like a nature recording from a forest pond.
I did cheat a little by downloading a thunder storm .wav file, but I think this is necessary to give the piece some ‘background’ noise. This was easy to set up and since the .wav file was long you can’t hear an obvious repeat.
The other three sounds are short .wav files. Two are drum sounds and the ‘frog’ is some electronic sound.
Basically I fiddled with the drum sounds, applying a random number generator to see what they’d sound like at random play speeds. These sounded ok, but I wanted the ‘crickets’ and ‘bugs’ to have more of a chaotic randomness to them. I achieved this by applying another random generator to the random generator, so that at any time the file could be playing up to a differing amount of random play speeds, greatly increasing the different sounds created. I changed these random numbers until I was satisfied with the ‘crickets’ and ‘bugs’ sound.
The frogs where built on a similer process. I created the one random frog sound at first. The play speed could not be set too high as the sound was nothing like a frog at all. The first thing I wanted to do after made one frog was to give him some buddies to talk with. So I copied him three times and set them up side by side. Here I realised that I didn’t need to copy half the code, all the frogs could access the same .wav file but could ‘croak’ at different times by using different random numbers for the play speed. So I rearranged them all and then had the best idea (well I thought so at least). I wanted to give the frogs some depth to their ‘croaking’. At first they where all linked to the same volume control. I looked at my laptop and imagined it was a pond with some frogs sitting around it. Then looking at the volume slider I noticed it had one slider for the left speaker and another for the right speaker. AHA! So I then changed it so that each frog had their own single volume control. I deleted 2 sets of volume sliders and linked each frog to one of the remaining sliders: 2 frogs in the left speaker, and 2 on the right. Each frog now had a place around the pond, and I set the volume for each to be quiet (for the frogs at the back of the pond) to loud for those that where close.
This lead me to give each sound its own volume slider so that I could alter them while recording.
I’m think the final outcome is ok. I could go back and add in a few bird sounds as well. One thing that I would really like to change is the pitch/tone of the frog croaks. If I have enough time I will try and figure out how to do that.
Below is a screenshot of the finished PD file. It looks a bit messy but I tried to neaten it as much as possible. I think there should be some way of making lines a different colour, and giving them a z-axis dimension so that it looks like some are going behind the rest of the program.
