Hello,
Is is possible in Pd to produce exactly the same envelope again and again? If I send the same message to vline and use this to cut an envelope out of noise or a sine wave, it always changes a bit (if you listen carefully). (The phase is always reset, that's not the problem.) I recorded the sounds, had a look at the soundfiles in an edit program and noticed that all the envelopes were slightly different. Then I used line~ in a subpatch with blocksize 1 and did the same thing. This sounds better and if I looked at the recorded sound files they were more identical (although the release changes a bit, there seems to be a very small inaccuracy in the delay... but you can't hear this with the sine sound. The noise sound is always a bit different, I guess because it are randomly generated frequencies?). Anyway I thought that vline~ was more precise than line~ but this doesn't seem to be true...? Have a look at the file in attach.
