c# - Sine wave clicking with Beep.BeepBeep -


originally, project make song in windows console using c# used console.beep(freq,time);, unreliability of caused desyncs.

i changed using beep beep class. problem when playing baseline, there audible click @ end of every note. here's example. single note it's not bad, many consecutive notes it's unbearable.

even when opened in wave editor, no matter cropped it clicked.

how can rid of clicking, without installing bulky libraries c# console project?

have tried ramping amplitude @ start of sound , down again @ end. so, modify inner loop of beep beep class, reads...

    (int t = 0; t < samples; t++)     {       short sample = system.convert.toint16(a * math.sin(deltaft * t));       bw.write(sample);       bw.write(sample);     }

could modified this

 (int t=0; t < samples; t++)  {      double ampramp = 1.0d;      if (t<1000) {          ampramp = ((double) t) / 1000.0d;      } else if (t > samples - 1000) {          ampramp = ((double) (samples - t)) / 1000.0d;      }      short sample = system.convert.toint16(a*ampramp*math.sin(deltaft * t));      bw.write(sample);      bw.write(sample);  }

this ramps amplitude first 1000 samples, , ramps down last 1000, may have change number of samples ramp.

networking - Vagrant-provisioned VirtualBox VM is not reachable from Ubuntu host -

this question exact duplicate of: puphpet/vagrant: unable access lamp vm ip address 1 answer i following basic vagrant tutorial , vagrant provisions box on ubuntu without complaining. moreover, can vagrant ssh vm. however, vm not reachable host: it's not possible ping it's ip address. what have achieved: installed virtualbox (5.1.24 r117012 (qt5.5.1)) , vagrant (1.9.7) onto ubuntu (16.04.2 lts) machine. provisioned vm vagrant up , vagrant finishes job , not complain. vagrant ssh works. i have manually installed lighttpd on guest vm , can ping/curl address: localhost within guest vm. this when trying reach guest vm host: ~/tmp/myfirstvagrantproject$ ping 172.22.22.22 ping 172.22.22.22 (172.22.22.22) 56(84) bytes of data. ... icmp_seq=4 destination net unreachable ... 171 packets transmitted, 0 received, +21 errors, 100% packet loss, time 173
