waveout

I need to make Delphi library / component that takes the currently playing sound ( it does not play my apps , just the general sound of what goes on loud-speakers ) returns me the data ( the amplitude of the left and right channels ) . Currently I have it processed by scanning from the microphone. He was looking for and I tried different VU meters that are on the net ( Torry ... ) , but they are not compatible with Win7 and higher. Anyone know of a solution? Thanks dont know if i understood corectly, if you mean how to get peak meter for default playback device you may try this: unit Unit1;

I am using the Windows waveOut API (aka MME or Multimedia Extension) mmsystem.h. Some programs change the audio playback sample rate (eg. from 44.1kHz to 48kHz), and it would be very useful for my program to detect the current playback sample rate, so it can warn users that Windows will be resampling the program's output. According to this documentation http://msdn.microsoft.com/en-us/library/aa909811.aspx , waveOutGetPlaybackRate returns the resampling % that the device is currently performing (eg, device plays at 44.1, and program is playing audio at 44.1 so it would return 1.0). I am

I'm having a debate with some developers on another forum about accurately generating MIDI events (Note On messages and so forth). The human ear is pretty sensitive to slight timing inaccuracies, and I think their main problem comes from their use of relatively low-resolution timers which quantize their events around 15 millisecond intervals (which is large enough to cause perceptible inaccuracies). About 10 years ago, I wrote a sample application (Visual Basic 5 on Windows 95) that was a combined software synthesizer and MIDI player. The basic premise was a leapfrog-buffer playback system
