1.1.1 iPhone firmware offers low-rent Push-to-Talk

Although I knew that the 1.1.1 firmware update introduced more attachment viewing support, I didn't realize until now that it added AMR playback. AMR, if you don't recall, refers to Adaptive Multi-rate Compression. It's the audio data compression format used by the iPhone for both voice memos and (if you've installed my Voice Notes application) voice recording. AMR is used primarily to store spoken audio.

So why is this big news? Well, if you're very very patient and you don't mind waiting for long gaps within a conversation, you can now use your iPhone as a very low-end push-to-talk device. By this I mean, you can install VoiceNotes and use it to record short messages. You can then email those short messages to a friend and they can play it back on their iPhone. To respond, they do the same: record and email.

This is obviously a long way from VOIP but as a stop-gap measure it works pretty well. I tested out a voice-only conversation the other evening and, while slow, the recording and playback quality was just fine for communicating.

Right now, the slowest part of the process involves addressing the message in Mobile Mail. If people show an interest, I'm considering either updating VNotes or writing an app that allows you to add the recipient's email once and then handles the addressing bit. Let me know in the comments.

Could VNotes record the conversation when talking with someone on the iphone?

This morning, my 1st install the VNotes using the installer. I can't record my voice, but when I call my voice mail, then I go back to the VNotes while I can hear the Voice mail, the VNotes can record the sound from voice mail but not my voice when I try to talk at same time.

I uninstall the VNotes then install the VNotes 2nd time, I can record my voice normally this time, but can't record the sound while call the voice mail.

Thanks.

I can't get SendSong to install on my unshackled 1.1.1 phone and, even worse, I no longer see VNotes in the application list under the sources in my AppTap installer button. Help!!!

Erica, that was actually the first thing I tried after installing VNotes... emailed myself and tried to play the attachment...

GO FOR IT !!!!

Vnotes is most useful 3rd party application I've installed. It's great for an impromptu brainstorming technical meeting that needs to be remembered.

My wishlist includes a playback facility within Vnotes with a pause button.

ups.. got cut off;-) ..our encrypted transfer. It gets send only to Nikotel servers (www.nikotel.com) and from there picked up from the recipient. And Nikotel offers these services since almost 8 years now. So that should be ok I guess. But if VNotes adds Push to talk it would be a nice flattery;-) And choice is good for customers. And I hope that is what all the development is all about. Giving choice. And todays announcement from Apple was a big win for all of us. So please let not engage in pointless bashing ("out of my comfort zone the "third party" (when then sending Vnote emails over 2 third parties!!)). By the way - you can not realize push to talk which works also if one is offline if it does not go through a "third pary";-) But that's just a little technical observation. I really like your work for the community and I am sure your role played a big role in making the iPhone a free phone:-) Thank you very much. I hope that our success on that platform plays a small role as well.

Hi there,

thanks for recognizing that Nikotalkie does indeed push to talk. That's correct. And compared to Email it only uses one server. So Emails go through 2 third parties. The SMTP server of the sender AND to the Email server of the recipient. For that I really prefer our encrypted

Erica: that sounds great, but what I am really missing from VNotes is the ability for that application to stay open while I go off into the Notes.app and take some written notes with the audio notes so its a one stop solution.

If you could add this feature that would be killer!

Some other suggestions less vital: perhaps a little level red levels and green levels to show you visually if you will end up with a good recording or not.

Keep up your excellent work on all of the iPhone apps - I look forward especially to PDFViewer and of course the amazing VNotes

@J.G.:

Do you use email? Why don't you just call people? Do you use IM? Why not call people?

I would say that this is a faster email now, and could be a verbal IM system in the future. And that IM and email are much lower (human) bandwidth than phonecalls - allowing you to have multiple conversations and do other things at the same time.

Hi Erica-

What would be more useful to me, is if there's a way to record audio with higher fidelity. I'm a singer, and AMR is really bad for anything but spoken word. I'd love to be able to record my group's rehearsals. Are there any WAV or mp3 codecs available for writing, or is there only AMR built-in?
