I'm wondering how I may obtain musical information such as amplitude from a audio file? Suppose we have a raw audio file, what I want to extract data from the file which allows me to generate a curve such as http://www1.icsi.berkeley.edu/Speech/mr/nearfar.html . Once I have obtained this curve, I will perform FFT, etc. I have been trying to search for solutions in Java Sound, but what I only know so far is that I can pour the data into byte[] using AudioInputStream . But how do I translate that byte[] into a double[] which contains actual information about the sound? In this case, the values

I'm getting a slight distortion (sounds like buzzing) in the background when I run the following code. Because of its subtle nature it makes believe there is some sort of aliasing going on with the byte casting. AudioFormat = PCM_SIGNED 44100.0 Hz, 16 bit, stereo, 4 bytes/frame, big-endian Note : code assumes (for now) that the data is in big endian. public static void playFreq(AudioFormat audioFormat, double frequency, SourceDataLine sourceDataLine) { System.out.println(audioFormat); double sampleRate = audioFormat.getSampleRate(); int sampleSizeInBytes = audioFormat.getSampleSizeInBits() / 8

I don't know very much about Java's MIDI function. In fact, it utterly bewilders me. what I'd like to do however is just build a simple application that will play one note. How to play a single MIDI note using Java Sound? The support for this out on the web is almost nonexistent, and I am totally at a loss. user2955146 I know this is a really old question, but, as a novice programmer, I had a very difficult time figuring out how to do this, so I thought I would share the following hello-world-style program that gets Java to play a single midi note in order to help anyone else getting started.

How can you play multiple (audio) byte arrays simultaneously? This "byte array" is recorded by TargetDataLine, transferred using a server. What I've tried so far Using SourceDataLine: There is no way to play mulitple streams using SourceDataLine, because the write method blocks until the buffer is written. This problem cannot be fixed using Threads, because only one SourceDataLine can write concurrently. Using the AudioPlayer Class: ByteInputStream stream2 = new ByteInputStream(data, 0, data.length); AudioInputStream stream = new AudioInputStream(stream2, VoiceChat.format, data.length);

When i capture with JavaSound or Third party sound capture tools and record it to a file. Afterwards read the file back to modify it, is there any way to remove the "background noise" with my java application. Such as road traffic/air noises while main person was talking? Thanks Removing background noise is very difficult. If it is uniform noise, such as the "white" noise on an airplane, there are algorithms to remove those frequency components. But if the noise is non-uniform and similar in nature as your good recording, e.g. people talking in the background, street noise, etc. it will be

I have packed all the class files and resources as a jar but on execution the sound files wont play. My package structure is: +project |_classes |_ _*.class |_resources |_ _ *.jpg,*.wav Code: AudioInputStream inputStream = AudioSystem.getAudioInputStream(kidsClassRoom.class.getResourceAsStream("../resources/"+file)); getting a null when this line is executed!! An alternate theory to those already presented. Often successful getResource() calls depend on the class loader instance that is called to locate them. For this reason, I would recommend to use an instance of a user defined object, from
