What's new in this version (1.1.1):
v.1.1.1 have added some new features inspired by feedback from users:
- When playing you now get a preview display of the generated waveform.
- Presets wave frequency selection view offering the standard frequencies an engineer is familiar with (i.e. those on a 30 band EQ).
- Explore wave frequency selection view with Coarse and Fine sliders. Perfect for finding that frequency that's feeding back, resonating or other
Real-time generated signals for sound engineers to test equipment.
- Multiple wave forms: Sine, Triangle, Square and Sawtooth.
- Custom frequency selection from 2 Hz to 20 kHz.
- Frequency Sweep.
- Noise: White, Pink & Brown.
- Generated waveform display (not simulated!).
Please get in touch if you have any problems, spot any bugs, have a feature request or need help.
SECURITY NOTE: For your peace of mind we only ask for one special permission from your Android device (Phone calls: Read phone state and identity - READ_PHONE_STATE). This is because we have a setting which allows you to decide whether the tone generator should automatically stop when you receive an incoming call. We do not query the 'identity' of your device - just permission to monitor the 'state' of the device in case of an incoming call. Please do not be concerned as this is by no way a security risk to you. Even if we did inspect the 'identity' of your device we do not have any ability to access the internet / network so could not transmit this information anywhere anyway! This security note was added after we received concerns from a user worried that we appeared to be asking permission to read their identity. Unfortunately the Android operating system (specifically the sandbox within the Dalvik virtual machine) bundle the abilities to query phone state and phone identity in to one combined security permission (ie READ_PHONE_STATE). Hopefully this explanation will help allay fears that potential users might have over this permission being requested.

Great app... all you need for quick test on gear and its always in my pocket ready to go. Thanks Q!
Pink and brown noise cause force close on samsung moment, Android 2.1
Stable sound generator. Plenty enough features and waveforms for me. Not sure I'd trust it for calibration but if you need a generic tone its ideal.
Need to be able to generate -10 db tones, add that and I will DL again.
Nice usefull audio test app.
Great functionality, but why read phone identity? I don't see any reason this app needs permission to read my phone state and identity. That's pretty disturbing.
Nice usefull audio test app. Even better with latest update. Recommend.
this is wickedly helpful! (epic, 2.2)
