Software Reviews and Criticism

  Nice, simple and clean user interface

  I've been using this app every couple of times a year for a couple of years now. Sure, I've had some trouble at times with Audio inputs and configuration, but I can say the same of some really expensive professional audio apps. The real question is, what is this app for? If you're trying to do some fancy engineering work, yeah, the Oscilloscope is missing many standard features. If you're using is for musical purposes, same thing... Where are my musical notes? while it may be lacking in many advanced features, It does provide a very clean set of basic tools. I like to muck around with my music synth, and I can get a very quick idea of what my filter is doing or how my oscillator shape selection is giving me more or less harmonic content. My daughter used the app to do a science fair project and it worked brilliantly. I just want to pour some love on this app. It gets way more criticism than it deserves for a five buck app. Well worth the money IMO

  Can’t recognize pro interface

  I want to like this app - the graphics quality and response time seem really good. But it crashes as soon as it tries to use my BlackMagic Mini Recorder, which is the simplest interface available to ingest HD-SDI video. Practically any other sound-related app can see this audio with no problem. This would be a great tool for quality-checking imbedded audio, but if all it can use is the built-in mic, that isn’t much use. The developers never responded to my inquiry about this, and their website doesn’t exactly inspire confidence. Please, fix this bug so I can leave you an updated higher rating!

  Spectrogram is completely inaccurate.

  I tested this spectrogram with a sine generator, the scale is totally wrong. Playing a sine wave at 500hz registers as around 30hz? Are you people completely incompetent? What possessed you to make such a terrible, disfunctional app, and think you can get away with charging people money for it? A 1khz sine wave registers at around 72hz? This is so stupid. I want my money back. I hope no one actually buys this, thinking it will work for any sort of professional application. Thanks a lot. You guys are a joke.

  Works great and very fast spectrogram

  This app is working great for me as a real time spectrogram visualization. Very smooth, much better than the spectrogram than audacity, which is obviously implemented in a much less efficient manner. As for the accuracy concern of other reviews, I’m not sure why I don’t seem to have that issue.
