Re: [CM] env->channel, and float-vector->channel
You're talking about the length of each blip? In the env-channel case, the vector is treated as an envelope and applied to .015 seconds of samples, but in the float-vector->channel case, the vector itself is simply copied into the file. It only has 8 samples, so in the float-vector->channel case, the blips are 8 samples wide, rather than .015 * 48000 = 720 samples. (By the way, I think you don't need the insert-silence statement -- it just adds 48000 samples to the overall file length). ___ Cmdist mailing list Cmdist@ccrma.stanford.edu https://cm-mail.stanford.edu/mailman/listinfo/cmdist
[CM] env->channel, and float-vector->channel
Hi, I'm having some confusion about successive edits using env->channel vs. float-vector->channel. For example if I loop employing env-channel and a vector as an envelope, then I see the successive edits every 1k samples; but when I try to do that using float-vector->channel the spacing is squished. Float-vector->channel works fine if I employ the vector as envelope across the whole snd., but I'm failing to understand how to employ it for successive back-to-back edits within the snd. Thank you for Snd 18.7! Regards, Jim (set!
