Hit Every Note with MicDroid

The question of whether we can or cannot sing is usually not the right one to ask. Everyone can sing, but the problem lies in hitting the right notes with the right pitch and intonation at the right time. Since that is complex to do without many, many years of training, technology is out there to help us achieve this goal. In this case, XDA member intervigil wrote an application based on an app called Autotalent, which was a project from a DSP (Digital Signal Processing) student at MIT. In essence, the program can take in whatever you are singing and, based on predetermined parameters, it will make sure that the notes that you sing are with the desired pitch and intonation.

The app is in very early stages of development, and the dev still has a lot of work to do, including the GUI. However, intervigil wants to invite all interested devs to lend a hand and test on other devices, as the objective is to make this app universal.

I wrote a small app that basically produces the autotune effect. It’s based on the AutoTalent LADSPA plugin, by Tom Baran, available here:http://web.mit.edu/tbaran/www/autotalent.html
The app is available under the name ‘MicDroid’ in the market, and the source is available at my github,
http://github.com/intervigilium/MicDroid
There’s still a lot of work to be done, including pretty much the entire GUI.
Currently my priorities are like the following:

  • device compatibility, I have reports of failure on G1, MyTouch3G, Galaxy S
  • graphics (being worked on)
  • loudness
  • ability to play some kind of backing track (technically might be quite difficult)
  • sharing recordings via email/SMS/whatever

You can find more information about the project in the application thread.

Pebble Time Steel with Customizable Sensor Smartband

Previously I talked about the Pebble Time Kickstarter, and why I thought it was the most practical smartwatch to buy in 2015, and that I decided to be an early backer on Kickstarter. Well as of this morning an interesting development has come from my - currently - favorite smartwatch company. They will release the Pebble Time Steel variant alongside the regular Pebble, instead of say a whole release cycle down the road. The accompanying announcement along with the Steel,...

LG G Pro Lite Unsecured Boot Image and CWM Recovery

The LG G Pro Lite D680 is a budget phone that was released in 2013 alongside the LG Optimus G Pro, LG's 2013 flagship device. Unfortunately, it hasn't received much development attention so far… but XDA Recognized Developer laufersteppenwolf has now released an unsecured boot.img along with a CWM recovery. This is despite the bootloader being locked (which means there's no need for you to void your warranty!), and marks the first step towards custom ROM and kernel development for...
