Diapason Audio Generator - Reviews, Revenue and Downloads - Apple App Store

Description

This App is a powerful test tone generator. Yet it is extremely simple to use. No other audio generator App is as complete as this one whatever its price !

You can combine (add) up to 4 independent sources and send the result to left and/or right speaker. There is a phase switch for each channel.
Available test tone types are: sine wave, square, triangle, saw tooth, white noise, pink noise.
As you can see on sample images, first source is very basic and thus very easy to use. Second source is more complex and allows sweeping of frequency for sine waves. Third source is quite similar to the previous one except that frequencies are aligned with a musical scale (reference is 440Hz). Fourth source is for narrow band noise.
Rotating knobs are there to ease frequency selection.
The display at bottom of first tab is a rough waveform viewer, to monitor the generated signal.
The output RMS power of a channel is indicated. Clipping is indicated as well should it occur (sources are added).

Any comment, any feedback ? There is a blog for this.

Note that the built-in speaker cannot reproduce the highest and lowest frequencies (below 400 and above 11000Hz to give an idea). You will ear these frequencies only with a good headphone or HiFi system.

Another fantastic App!

Works great! Bought this app just for fun after using the creators SPLnFFT noise level meter for an environmental noise study I did. Both apps are solid.

Was good app; Won't work OS 5 or 5.01 V1.4 iPhone 4

I hope app designer can fix; this has been a great broadcast test tool till the OS change...Will do microphone levels into 600 Ohms.

Doesnt work in IOS 5

Worked great till i upgraded to IOS5

Need manual!

Love the app. But I don't see where the blog is? I can't figure out how to make source "B" be on right channel while source "A" is on left...

OK up to 8 kHz

Above 8 kHz the audio starts cutting out. Nothing above 9 kHz.

Good generator but no manual

I like the flexibility of this generator but it misses a manual. The "i" area does not reveal any information when touched, which is perhaps a bug. Once that it fixed and a good help / manual information shows I consider more stars.

5 Stars!

Awesome app!! There are other tone generators out there, but this one is well worth the cost! Does everything you need!
