DTMF

DTMF decodes and encodes DTMF (Dual-tone multi-frequency) tones trough the phones speaker and microphone.Encoder: Always 2 tones are assigned to each key.The length of the tone and the pause between the tones can be set from 35ms to 1500ms.A total of 36 marco’s can be used to play phone numbers, ham radio auto patch numbers, amateur radio echolink id's any many more.The 36 macro's can be saved to the phones/tablets memory. This way a unlimited amount of macros can be used. The DTMF tone length and the pause between the tones can be adjusted.Decoder: The decoder detects the DTMF tones and prints them on the screen. A sophisticated algorithm detects the tones even in noisy environments.Please let us know what you think. If you like DTMF please leave us a feedback at Google Market.

Nice app, UI is a little outdated but it does as advertised. If it integrated with tasker or at least made some sort of system broadcast when DTMF tones were recieved it would be amazing. Especially if it could be done in the background and dtmf macros could be triggered by tasker or shortcut. Lots of potential in this app

Needs more options You should be able to have an option where as the longer you hold down a key the longer it continues to make a sound. There should also be an option in the macros where you can enter the duration of each recorded tone. For instance if I dial "0501#A" I might want the tones of "0501#" to be long, but I want the tone of the "A" key to be a very short burst of tone. There are some devices that actually require this. This should be programmable in the macro options but it is not

The app does what it says it does. And it's pretty much the only decoder I I could find. But as other users have said this app would be heaps better if it was able to interface with tasker via system broadcasts or even if it just outputted to a log file. When you lock the screen the mic stops listening so I could need a way to run in the background hence why a tasker plugin makes more sense.. I had a few numbers register multi times when I had only generated the DTMF sound once..

Probably the best DTMF app on the market here. I've been using it for over a year now and it has come in handy for several projects that require generating and decoding DTMF tones. Would be cool if the designers upgraded it with some extra features. I own several other apps made by Wolphi LLC and they all perform flawlessly.

Very high accuracy in decoding tones, top notch. Better then any other app on the market. Highly recommend. Money well spend.

Absolutely does not send tones through phone... Useless to interface with remote boxes

This app simply does NOT work for use with your own smartphone !

I thought it would record tones played during a conversation 8

other apps have choppy dtmf on my s4 . You can adjust tone lenght and pause. the dtmf decoder is not right thouht. I can trigger dtmf with wistle

After others failed, this one worked.

Great app, smart and easy to use with more than 90% accurate

This is a very useful app to have in your phone.

Great App + IT WORKS.

Should add ability to add a number from address book

Out of all the dtmf decoder apps I've tried, this one actually works.

Keep up the great work!

* Does not allow copy-paste (via long-press or any other method), e.g. to paste in a long number for playback, from another app. * Crashes when, in playback mode, the Clear button is pressed while playing back a long macro. I can reproduce this bug, but not 100% of the time: it seems to occur when Clear is pressed while the display is being updated with the current digit.

Perfect to the task.

Fantastic, reliable DTMF decoding. On my LG Optimus V the encoder output volume is next to silent unless a headset is momentarily plugged into the phone after which everything works fine. My only suggestion for improvement aside from the playback volume issue for my phone is to include the ability to trigger an alarm if a predetermined tone sequence is received.

Works better than some of the other apps I tested but hardly ever gets the entire code right, misses some and doubles others, get an incorect digit every now and then, HTC Wildfire S.

EXCELLENT!!! Decoder works great on Samsung Galaxy Nexus (Sprint) and sending dtmf tones has loud enough volume.

Just as advertised :) Exactly what I needed for IRLP work with non-DTMF mics! 73 de KJ4WLH

Perfect for hamradio use. Love it. Works great. AE7HF

This is the only app that actually works. Well worth the $ :-)

Works as stated.
