This app cleverly uses your sound card to display an oscilloscope and spectrum analyzer for examining music, speech, or circuit output, but it doesn't have much in the way of user instruction. Zelscope's plain display mimics the look of hardware oscilloscopes. If you feel comfortable around those dials and sliders, you'll be right at home with this app. The short FAQ will not teach you how to operate this app.

Zelscope accurately tracks your sound card as it converts analog sound to digital. Manipulating the basic gain, offset, timebase, and trigger sliders and buttons is very easy. The oscilloscope display is clear and responsive. The app includes easily set features to save data as BMP- or EMF-screen shots, WAV or TXT files, or send info to the printer.

Users with any need to analyze music, speech, or circuit output should give Zelscope a test. The 14-day demo is not hindered in any way, which gives knowledgeable users ample time to test this app.

Definitely worth $10 as opposed to costly oscilloscope
Dubble_M_256March 18, 2012
Pros
Cheap alternative to an oscilloscope. For measuring fairly low frequency signals, like RS-232 or a Servomotor PWM line, this is easy to use and formatted like a normal oscilloscope. The FFT works pretty well also. Overall, the program is pretty responsive on my system and very reliable for the tasks I mentioned.
Cons
The above comments are true: No User Manual, 22050 Hz Max (which is half the max sample rate of 44.1 kHz, so it could never go higher), and does not do DC signals (but that is a characteristic of the high-pass filter of sound cards, so it has nothing to do with this program). It lacks some of the features common to many oscilloscopes. It does not have these, but I would add: + A "single" button, so it would catch and freeze the first waveform that is triggered. It looks like the program may have this feature somewhere, but a button by the run/pause buttons would help also. + A longer buffer. You can hardly turn it up past 5ms/div, (which is a window of 50 ms).
Summary
I give the five stars for a $10 product. If it costed any more, I would add some features. The biggest limitations of this program are ones that are limitations due to the properties of a normal sound card. For the most part, if you have had experience using a typical oscilloscope, then using this product is a no-brainer. If they added the features I talked about, the product might just be worth more. However, this products take a good idea, using the sound card's line input, and turning it into a useful alternative to an oscilloscope.

Pros
NICE IDEA IF USER MAULAL AVAILABLE FROM SELLER
Cons
HAVE TO FIND YOUR OWN WAY; DIFFICULT FOR NOVICE
Summary
CHEAP
Works as advertised useful for audio, spectrum analysis

Pros
Easy to use and gives a good display with typical scope controls.
Cons
Low frequency response, up to about 20khz only, AC only, no manual
Summary
Worth the price $10 for anyone needing to check audio inputs and check audio characteristics of inputs, I use for checking audio signal while restoring old recordings.
