I am having trouble in converting the audio format of a WAV file. I am recording sound from my microphone and the sound is recorded in the following format: PCM_SIGNED 44100.0 Hz, 16 bit, mono, 2 bytes/frame I want to convert the above format to, ULAW 8000.0 Hz, 8 bit, mono, 1 bytes/frame I am using the following code, InputStream is = request.getInputStream(); AudioInputStream ais = AudioSystem.getAudioInputStream(is); AudioFormat oldFormat = ais.getFormat(); AudioFormat newFormat = new AudioFormat(AudioFormat.Encoding.ULAW, 8000, 8, 1, 1, 8000, false) ; AudioInputStream lowResAIS =

What's the simplest way to generate a sine wave sound at any frequency in Java? A sample size more than 2 bytes would help, but it doesn't really matter. Thanks Andrew Thompson See Beeper for a self-contained example. Perhaps something simpler? That 51 lines of snippet (repeated below - spaced out for single line & in-line comments) as shown at the top of the linked answer, is about as simple as generating a tone gets (OK, you can take out 5+ lines for the harmonic). People seem to assume it should be a method built into the toolkit to produce a pure tone. It is not, and takes a little

I have designed my own synthesizer in java and I now want to connect it with a midi keyboard. My class below searches through all the midi devices that have transmitters. It successfully finds my midi keyboard. I add my own receivers to each transmitter for each device so that it should pick up everything possible. From reading all the help documents and java doc I know that a Transmitter sends MidiEvents to a Receiver which then handles them with the send method. So I wrote my own inner class implementing Receiver and just used a println statement to check if there was anything detected at

First off this is for homework or... project. I'm having trouble understanding the idea behind how to draw the sound data waves on to a graph in Java for a project. I have to make this assignment entirely from scratch with a UI and everything so basically making a .wav file editor. The main issue I'm having is getting the sound data into the graph to be drawn. Currently I have a randomly generated array of values just being drawn right now. So far I have a mini-program running and validating the wav file for it to actually be a wav file. I'm reading it in with a FileInputStream and validating:

I'm trying to read in .MID files to a Java program, and would like to separate each note/chord so as to display them on a UI of some sort. I didn't have much luck using the Sequencer API in Java, and trying to use MidiFileReader directly didn't work for me either. I'll attach the code I used here, if anyone wants to see it: package miditest; import java.io.File; import java.io.IOException; import javax.sound.midi.InvalidMidiDataException; import javax.sound.midi.MidiSystem; import javax.sound.midi.MidiUnavailableException; import javax.sound.midi.Sequence; import javax.sound.midi.Sequencer;
