About 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 make it run in the background too. I recorded a series of DTMF tones with the builtin Voice Recorder and then play it back while this Receives goes in the background.. and it didn't catch it. I want to build a small automation to start my car remotely and for that I need this app to listen (in the background) non stop and a way (API) to read and clear the receive buffer from another app (that I will create). Or simply add a 'passworded relays automation' feature where the opto-link between the phone and the external relays is made by lighting/displaying some 1cm radius circles on a black screen

* 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.

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

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.

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 well - dtmf volume needs to be louder

However it would be nice if it did 2 tone 1+1 decoding as well. The search continues. Excellent DTMF though.
