[3] DOCUMENTATION - As a developer I want the old code used by the pentagrom app so that I can convert from midi to pentagrom format

[localaization]

Description: Since a mobile app was developed years ago, the sourfe code must be somewhere. We need to find it.

Documentation: Please check this repository: https://github.com/localaization/pentagrom-android-app

Some example videos about the old app can be found here: https://www.youtube.com/@pentagrom_es2489/videos

From source code

Android midi implementation LeffelMania: https://github.com/LeffelMania/android-midi-lib/tree/master/src/main/java/com/leff/midi

Android Open Source - audio-analyzer-for-android Real Double F F T: http://www.java2s.com/Open-Source/Android_Free_Code/Sound/audio/com_google_corp_productivity_specialprojects_android_fftRealDoubleFFT_java.htm.

Tasks

• Get written music samples converted to our format: we have then [x,y,c,k, freq] localaization
• Get the same samples in midi format. So for a given midi code in a song, let's say 66 which might be two notes F#4/Gb4 we have the ground truth because either [x,y,c,k,freq,66] or [x1,y1,c,k,freq,66] is the result in our written music samples
• The training dataset will have [x,y,c,k,freq,MIDIcode] of the songs, where there is only one MIDI code per note from here we could do any mapping

QA

• Get the old code
• Convert one song

Definition of Done: We have the source code available for this project and we are able to "transcript" one midi file.

We don't have the code of the last development app, we will try to contact the very first developer's team.

[localaization]

Added LinkedIn contact of the very first developer.

[localaization]

We have sent emails to Luis and Rafa (the very first developers) to check if we are able to gather the source code of the first app.

[localaization]

Luis email is not valid anymore, let's wait for Rafa.

[localaization]

We are trying to contact Luis through Linkedin. Contact invitation sent.

[localaization]

No update, I'll try the last resource, trying to contact another person involved at that tiime.

[localaization]

Good news, we have the source code, I didn't review it but it should be the java/android I guess. I'll let you know.

[localaization]

Hello guys, I need to ask Jaime about legal concerns before sharing the code. I'll move task #2 to in progress, leaving this one on hold.

[localaization]

Looking at the code, I'll be updating documentation in the description of this task.

[localaization]

After talking, updated one strategy in the Task section and some documentation has been updated.

[localaization]

We will bypass most of the code. We are doing it in another way. But this task is done, the old code is in the repo.
