Needs to keep the phone on while generating! Also cant keep a steady signal for more than a few seconds at a time. Constantly cutting out and turning back on made it a huge pain to set 2 mics levels instead of a 10 second job.
Ui is simple, capabilities are good. However, it drops out practically every time the phone moves, and periodically freezes the phone. Great for those who enjoy frequent hard reboots. Android 4.3 on Samsung Galaxy 3s
Locks the phone up when the screen turns off. Takes ages to redraw the screen and unlock the phone. Unuseable. Uninstalled it within five minutes of testing...
Nice to be able to select the frequency but some of the waves don't work. Sine just generates a clicking sound, others produce the wave and clicking. Triangle is only one that works right
Thanks for the great app. However, when I plug in my headphones, the tone drops and only pics up the external microphone. Could this possible be addressed in a future version? Thank you!
Not convinced this works on the S4. Works excellently on my Note and Desire though
Needs to be able to run in background
Awesome thanks for creating this app
Tone generator, white/pink noise, nice. But it doesn't keep playing if you switch to a different app, and a plain background would look better.
Interface clumsy and too few control. Scope useless, would need refresh rate tuning and signal output to Mic input comparison to be of some use.
Love it really when u wana c wat happens when u put it @ a low note and just c your subwoofers just quaking backin forth :) great for spl
I wanted something to generate different sine waves and it does that reasonably well. There is allot of audible distortion in the higher frequencies.
The waveform viewer is kinda worthless, and the volume jumps when the window rotates.. but the noise is actually random, not just a looping segment. Kinda awkward interface too, but it does the job!
Doesn't play unless screen is on, huge CPU usage. cool that it uses the mic to display on the scope but there is no way to turn it off. Uninstalled.
Keeps resetting output volume, so I can't get a steady 50mv output to test audio equipment.
Gnexus Toro here, lagged my phone so bad that I had to pop the battery out. I was using it to test mic lines, and it only worked half the time. I ended up just playing music instead.
Good app - pegs CPU over 99% & gets hot. Continues to run after exit @ high CPU usage. Sets off watchdog warning.
Sound does not stay on when phone screen is off. Makes this useless to use while sleeping. Uninstaling!
Very nice app! Simple, intuitive and does what it says. I'm using it on my nexus S to do some experiments on sound wave propagation, and it serves the purpose well enough.
...plug in the mini jack and then connect to input terminal (audio input) of amplifier. Great! my galaxy mini became 'small & handy' signal generator for testing my D.I.Y. sound system.
Works perfectly on my triumph. Thank you!
What's the point of generating the sound if no file saving is allowed? 5 stars if allow file saving. It does the job.
Simple, does exactly what i want.
Does what it says. Motor ATRIX.
86%cpu load when not in use, not good.
This thing scares me
Why do I need to see the Mic input if I'm just want a tone??
Yes it is.
Like all of Julian's software, simply the best. I am an electroacoustical engineer, and use this to check systems, RTA acoustics, stress speakers, and even find meditation resonance (AUM) frequencies. Dear bro, thanks for all the good stuff...
