Hi, there. I would appreciate so much your help for me to decide if
I will accept a job and how to go on with it.
I have a customer who needs an Android/iOS app that they will give
to his customer who buys them a "device" (this customer of mine is
not a multimillonaire company. It's far away from being like that)
The app would be something like the mockup.png attached and will do
something like this:
First instance:
- It opens a wav/mp3 (max: 1 hour).
- You will see the soundwave and will can make zoom in/out to be
precise (if with gestures, much better).
- You will can play/pause/stop the audio from any place in the
timeline.
- You set up to 256 markers/labels in the timeline.
- When you click/tap a marker/label, a new window appears to modify
its information (time/color/type/etc).
- It will convert each mark to a 6 bytes group.
- It save/load files with all this markers (in binary).
- It will send this file, by Bluetooth through the serial port, to
the "device".
Second instance:
- The app will start playing the wav/mp3 file.
- It will send (by Bluetooth) the "start" command to the device.
- (The device starts its timer and already has the sequence file).
- For a perfect syncrhonizing, every second, the app will send the
actual time (by Bluetooth).
I have several options to do this. I ask you if they are possibles
and how difficult are they... and the final decision owns to the
customer. My skills are: I know PureData and Python. So:
I know it is not a framework. I would make a PureData patch and the
MobMuPlat interface. My customer would tell their customers to
download MobMuPlat (Android:
https://play.google.com/store/apps/details?id=com.iglesiaintermedia.mobmuplat,
iOS: https://itunes.apple.com/ar/app/mobmuplat/id597679399?mt=8) and
give them the file that I build.
Pros:
- It's the easiest-way.
- MobMuPlat is already in Google Market and iTunes.
Contras:
- It is not a standalone app, as they would like.
Doubt (and it's important):
- Could libpd send messages to serial port? There's [comport], but
it is an external. Is it already compiled for Android/iOS?
This is a more difficult option. It uses Python to make the app.
And there's Kivy/audiostream (https://github.com/kivy/audiostream)
that gives the phone a access to the speaker and mic. In its
example/ folder, there are puredata examples. Obviously, using
libpd.
Pros:
- I would also make the patch in PureData.
- It would make a standalone app (with own name, splash screen,
etc).
- It would works in Android, iOS, Windows, Linux, OSX.
Contras:
- I've never used Kivy.
- I've never used any framework.
- I've never used libpd.
- I should build almost from scratch an application.
- I should compile for most Android and iOS versions...
- The difficulty of uploading an app to Google Market and iTunes.
Well... I don't know coding C++. I know that this would be the
best framework to do something like this... but it's furthest away
from me. There's ofxPd (https://github.com/danomatika/ofxPd).
Using PdDroidParty and PdParty
Now, I'm seeing their webpages/githubs. I didn't think in this
possibility... Could it become one more?
Pros:
- Another easiest way.
- It could compile a standalone app (???)
Contras:
- As other frameworks: What about compiling for most Android and
iOS versions...?
- Uploading to markets...?
Thank you very much!
Mario Mey.
