Behringer c1u review and sound test

HI guys today I'm here with this short review of behringer c1-u mic.
It's a condenser usb microphone, it works well with acoustic instruments (piano, guitar, voice) it costs about 70$ and for its price it gives good quality sound.
Of course if you have to record a piano professionally isn't the right mic but for homemade recordings it's good.
In the box there is the mic, the support for the mic, and a 6m long usb cable.
Here is a simple sound test of the microphone with my upright piano (song: the great gig in the sky by pink floyd):







I hope you enjoyed the post, if you have any question just ask :)

Where to get free piano music sheets

I'M NOT RESPONSIBLE OF YOUR USE OF THE INFORMATION GIVEN IN THIS POST.
There are mainly 2 sites where you can find music sheets for piano :
-pianofiles.com : it requires registration but then you will be able to trade with other people and about 4 million of sheets
-scribd.com: this isn't particullary made for music sheets but you can even find some. This also requires registration.

I hope you like this post, if you have any question comment or send me an email to damianoandre@gmail.com

Quick tip: update music library android

Hi, this is just a tip that I found useful when I added new songs to my phone but they weren't displayed in the music library.
- Go to settings>apppications>manage applications and find a system service named "media storage"
-Click the button "clear data"
-unmoumt and then mount sd card

And here you are!

I hope you like this post :)

Processing music frequency visualizer super mario version

Today I'm posting about a new project in processing that uses minim audio library to visualize frequency using super mario tubes.
I think it's cool, here is the code

import ddf.minim.signals.*;
import ddf.minim.*;
import ddf.minim.analysis.*;
import ddf.minim.effects.*;
import ddf.minim.ugens.*;

Minim minim;
AudioPlayer song;
FFT fft;

String song_file = "song.mp3";
PImage tube_up;
PImage tube_sec;
PImage bg_mario;
int m = 3;

void setup(){
  size(1200, 622);
  tube_up = loadImage("tube_up.png");
  tube_sec = loadImage("tube_sec.png");
  bg_mario = loadImage("bg_mario.png");
  frameRate(60);
  minim = new Minim(this);
  song = minim.loadFile(song_file, 512);
  song.play();
  fft = new FFT(song.bufferSize(), song.sampleRate());
}

void draw(){
  background(bg_mario);
  fft.forward(song.mix);
  stroke(127, 255, 0, 200);
  for(int i = 0; i <= fft.getFreq(80)*m; i++){
    image(tube_sec, 10, height-(10+i));
    }
  image(tube_up, 10, height-(74+fft.getFreq(80)*m));
  for(int i = 0; i <= fft.getFreq(150)*m; i++){
    image(tube_sec, 180, height-(10+i));
    }
  image(tube_up, 180, height-(74+fft.getFreq(150)*m));
  for(int i = 0; i <= fft.getFreq(200)*m; i++){
    image(tube_sec, 350, height-(10+i));
    }
  image(tube_up, 350, height-(74+fft.getFreq(200)*m));
  for(int i = 0; i <= fft.getFreq(300)*m; i++){
    image(tube_sec, 520, height-(10+i));
    }
  image(tube_up, 520, height-(74+fft.getFreq(300)*m));
  for(int i = 0; i <= fft.getFreq(400)*m; i++){
    image(tube_sec, 690, height-(10+i));
    }
  image(tube_up, 690, height-(74+fft.getFreq(400)*m));
  for(int i = 0; i <= fft.getFreq(500)*m; i++){
    image(tube_sec, 860, height-(10+i));
    }
  image(tube_up, 860, height-(74+fft.getFreq(500)*m));
  stroke(255);
}

I think it's a simple sketch so I won't explain how does it function.

You can download the sketch and the file you need to run it here.
You can also try a web version here(java required).

The demo song that I put in the zip folder and that I used in the web version is
Drive Hard - PrototypeRaptor

I hope you like my post, if you have any question please comment or send me an e-mail to damianoandre@gmail.com

P.S.:probably next week I'm gonna post about a TV B gone made using arduino and an Attiny85

Arduino and processing led blinking following music rythm

Hi,
Today I'm writing about a simple project with Arduino and Porcessing to blink 5 LEDs following the music rythm.
To do it we need an audio librari for processing called minim, (created by Damien di Fede) and we need the Firmata library for communicating to Arduino.
For this project you need:
-Arduino board
-5 LEDs (1,8-2v)
-5 220ohm resistors
-breadboard
-some wires
-arduino library for processing (http://www.arduino.cc/playground/Interfacing/Processing)
-minim audio library(http://code.compartmental.net/minim/distro/minim-2.0.2-lib.zip)

First of all prepare the simple connections on your breadboard following this image:

Then open the arduino software and upload the standardFirmata sketch (File>examples>Firmata>StandardFirmata).
Now, before writing the processing code I'd like to tell you something aboute the libraries we're going to use: Firmata is a library made for communciating between processing and Arduino. When you run Firmata in arduino, you can call arduino functions from processing using the arduino library for processing.
The minim library is an audio library for processing, I think it's the best library about audio and sound for processing because it's easy to use but have lots of functions. For the reference chek this link: http://code.compartmental.net/tools/minim/.
Now download the libraries and write the following code in a processing sketch:

import ddf.minim.*;
import ddf.minim.signals.*;
import ddf.minim.analysis.*;
import ddf.minim.effects.*; //Import ddf.minim library
import processing.serial.*; //Import serial library
import cc.arduino.*; //Import Arduino library

Arduino arduino;
Minim minim;
AudioPlayer song;
FFT fft;
//I create the objects

//To play another song change the song_file value
String song_file = "song.mp3";
int xmax = 600; //window width
int ymax = 300;//window height

void setup()
{
  size(xmax, ymax);
  minim = new Minim(this);
  arduino = new Arduino(this, Arduino.list()[1], 57600);
  song = minim.loadFile(song_file);
  song.play();
  fft = new FFT(song.bufferSize(), song.sampleRate());
  // in this function I create the minim object, I start
  //communicating with Arduino,I load the song and I play it and
  // I start the Fast Fourier Transofrm
}

void draw()
{
  background(0);
  fft.forward(song.mix);
  stroke(127, 255, 0, 200); //I set the color of my lines
  for(int i = 10; i < fft.specSize(); i++){
    line(i, height-30, i, height - (30+fft.getFreq(i*10)));
    // I create lines that represent the amplitude
    // of each frequency.
    text("Min Freq", 10, height-10);
    text("Max Freq", fft.specSize(), height-10);
  }
  ledcontrol(); //I call the function for the arduino
}

void ledcontrol(){
  //In this function I use arduino analogWrite function
  // to write in PWM pins the amplitude
  // of five general frequency
  arduino.analogWrite(3, int(fft.getFreq(500)));
  arduino.analogWrite(5, int(fft.getFreq(400)));
  arduino.analogWrite(6, int(fft.getFreq(250)));
  arduino.analogWrite(9, int(fft.getFreq(150)));
  arduino.analogWrite(10, int(fft.getFreq(80)));
  }

The code is simple so I think it's not necessary to explain it.
You can download the project files (.zip) here: download.
Here is a test:
