Audio output monitor
The application displays the default final audio volume level, both overall and by channel. The sound is analysed and graphed as a frequency histogram, raw frequency (fft) distribution or oscilloscope plot. I have used the excellent libraries from https://www.un4seen.com/ You will need the following libraries in the application folder: bass.dll basswasapi.dll The code relies on a modified version of modspectrum.bas taken from the examples downloaded from the site. The pc must have a loopback audio output device. The compiled exe is stable and has been tested on my 64 bit windows 7 PC and my windows 8 laptop. My xp setup did not have an audio loopback device. The bass dll's employ callback which is notoriously unstable under the vb6 IDE. So running the code in the vb6 IDE environment is unstable. I simply compiled the exe and tested that during development. Expect to have to do the same and save all active forms before attempting to run in the IDE. David
