Question CRO App to see internal sound in real time (free) ?

[REALOldNick]

Hi. I am after a piece of software that will hook into my PC's sound system and display the waveform of sound being played not just from a sound file. Ideally I would like to be able to set the input device so I can see what is happening at various stages in the sound path, from source to actual card out. Mind you I have a hardware CRO that will do that last one no problems.

Any help appreciated.

As I understand your post the requirement is for some audio sprectrum analyzer software.

I googled "sound frequency software for pc".

Results: FYI (Reference only - not a recommendation or endorsement):

Take a look at the link and the listed products. Pay attention to the words, terms,and descriptions being used.

Then use those terms, words, and descriptions to do some additional google searches filtered as necessary for your specific requirements.

No, not spectrum analyser. Waveform display. So Oscilloscope.

Pay attention to my post, before you lecture me, please.

"Thus, spectrum analyzers and oscilloscopes are instruments that measure electrical signals. The main measurement object is the amplitude of the signal, amplitude information will be displayed on the vertical axis of the 2 instruments (Note 1). The difference between the two is that the horizontal axis is different, frequency is the horizontal axis of spectrum analyzer, and the oscilloscope takes the time as the horizontal axis. In other words, the spectrum is used to observe the signal in the frequency domain and the oscilloscope user to observe the signal in the time domain. "
