Audio MODEM

I love this awesome app!!! I want to see improvement like a clipboard or a feed to see what's going on the canal. That would be awesome! Many thanks! Edit#1 the app does not work on android 10

For Broadcasting Audio MODEM app Works perfectly everytime. Sent commands R picked-up & even picked-up by relayed receivers. My commands hit the pick-up & keyed in by the main modem correctly. Receiving, Myself its hit or miss getting the responses within the App outwild public to my sent comm. Not knowing how this app handles receiving an App usage page/manual would probably correct my issues explaining how modems work lessen poor rating

Love the app. Future improvement or features i d love to see -Recognizing text by speech -automatic recognition of rx and tx -possibilty to create a soundfiĺe from the output and import of recorded files. i hope you ll have the time to improve this great app. all the best

please make app to go from TX to RX automatically, some people are sending more than one message, please add feature for delayed sending so my VOX will be able to register and open before it is too late. I also would like to adjust speed and low/high frequency

Crashes now and then on receive. But fun to play with. Use an AES text encrypter and transmit messages over a CB or UHF radio, even a phone call to teach kids about digital communications by sound.

Wow, that's a great idea. much liked it. Can you make an application that cast smart phone's screen on any tv. Whith an audio jack and av cables. Just like a "psp". Then we can cast smart phone without any casting device. That's my request to developers.plz reply

Awesome! Thats being good if you make a app which works with files (sending files) through the radio.

Great App ! How could i thank you. Because of you only i able to do a such big project working easily. Please add some more features.

Awesome idea. would be cool to be able to create and decode audio files.

Interesting idea, UI could do with a touch up.

It's awesome but I wish you could choose different modes like qpsk or qam

Good application but can transmit small text.

❤️❤️❤️❤️ Thank you Please make it to create a mp3 And hear a mp3 sound file Of modem...Please thank you

pick an mp3 to modulate, lo-ky on the sly sending?

wonder why its not been updated since 2015...

2nd Review after a while of use: While the transmission stream sounded fine, I don't quite get why there is a beep at the preamble of the transmission, couldn't it sound like the rest of the TX stream or could it be omitted? It seems to bother me because a actual radio TX I know if don't usually have a distinct sound at the beginning—in fact, it kind of sounds like my notification beeping sound.

This app works great and has alot of potential, ome thing I would like to see added is a higher file size limit (I like using it to transmit my html code around )

Tested the application with multiple phones, keep getting bad checksum error.

App crashes when receiving data on Amazon fire tablet HD 8 (7th gen)

Can't wait to connect this to an fm xmtr or walkie talkie to see if it works. Kinda wish you didn't have to press receive every time but not a big deal. I'm sure I'll be use the python code anyway.

One of a kind App. I like the idea very much. Could this be modified to act as a coupling to the Phone Audio so that a Smartphone could be used to connect with a Fax machine? If so you could add a RIP interface for documents and have the worlds first true Direct Smartphone Fax !!! Much money $$$ :-D

My only limit is that it only allows text up to 250 bytes. It would be much nicer if I could transfer files, or at least an unlimited amount of text! I would support this any day!

Text transfering is great, i need to transfer image. is it possible, if yes then how is it

Ultimate use of tone... roman i wud like to know the algorithm u have written to implement this app..

Best way to easily transfer links between my old devices. Very fast.

Works great and is reliable at up to 40 cm between two phones.

Really waiting on the >250 char limit.
