I’m working on Audio tuner application in order to tune musical instruments.
User should play a note, then in my application I should show which frequency it has.
The first, I should access to microphone?
AudioRecord recorder = new AudioRecord(MediaRecorder.AudioSource.MIC,
sampleRate, AudioFormat.CHANNEL_IN_STEREO,
AudioFormat.ENCODING_PCM_16BIT, bufferSize);
Then I need to calculate frequency of sound. How can I do this?
I’m also trying to do this. I haven’t managed it myself yet, as I’m completely new to android development, but here are two useful links to the source code of other tuners, one in Java, one not:
EDIT:
Thought I better link to the MANY alternatives on this site with people trying to make a guitar tuner.
RE-EDIT:
FFT.java
Solved my problems. (Not linked properly because I’m a new user)
