SOUNDS

[kjm]

Is there any way of playing sounds under PocketC that have a user defined frequency and duration? Or is there any intention to offer such? Rather than load .wav files.

Not that I knew of a way of doing that. In my own guitar and drum composition programs (http://pages.prodigy.net/gwen.and.wolfgang) I use the "replay .wav files" method, which works well apart from the fact that it uses up some memory. I have also written some code that will create .wav files that contain sounds with given frequency, duration, and waveform, in case this is interesting for you.

Many thanks Wolfgang, but I don't really want the overhead of *.wav files. However, what I asked for seems to be a desirable request in a language. Maybe if Kevin is "listening" we'll get it one day?

Hi wolfgang:
Where is the code? I couldn't find it in your web.
I am interesting that. Could you tell?

I have some experimental code I developed while working on my FourTrack program. I used it to figure out how to write wav files. I did not put it on my homepage because it's really hacked together and not yet publish-able. However, I am currently working on a set of library routines to create wave files with custom sounds that can then be replayed, a crude work-around for the missing sound capabilities in PocketC. The main problem is that creating wav files takes VERY long on the little WindowsCE machines, at least several seconds for every second of play time. I will post this code on my webpage as soon as it is ready.
