Soundbeam

Plugged into the USB port of my piano and was very entertained by the waveforms generated. Great fun and well done.

Good luck trying to listen to your signal via an interface , the app blocks all audio when the Scope is running , utterly useless.

100% great! I love this application I use it to monitor modulation characteristics on my Ham radio with the external microphone input. The graphics are really good kinda hard to tell your not looking at a dedicated scope, in spectrum mode you can clearly see band pass filter roll off. I would like to be able to vary the time base in scope mode perhaps in another version or update you do have the option of adjusting the vertical gain in scope mode and selecting linear or logarithmic display in spectral mode.

best software scope out there

Love the UX and design. Great stuff. Would love an X/Y function though.

It works! Useful tool to have, very modest price. The user interface is real eye candy - in the same vein as the first AAA apps designed for iPhone. Really happy with this. Thanks for creating it. I don’t see an approximate dB level when in waveform mode. That would nice.

Absolutely LOVE Soundbeam and especially appreciate the ability to record and save audio + video. My two requests are: enable longer recordings (IAP for this function would be welcome and purchased immediately) and (far less important) the ability to adjust background color from the default aqua-green. Regardless Soundbeam is awesome as-is.

Quite useful to capture oscilloscope waveform videos for synthesizer videos, except it only records 14 second videos ... I was looking for an IAP for longer videos immediately, but couldn't find one.

My iPhone reset when I was playing with the app :) Any plans for supporting 6/6 Plus?

This is really cool if you're an engineer or geek. Well worth $.99.. I'm sure the iPhone's mic has a certain frequency range, but does it really cutoff at 100hz? Would be nice if it could go lower, preferably down to 20 or so hz, which I'm sure the mic isn't capable of. Maybe with an external mic the scale could shift down to 10hz? Please make it as low as possible!
