![]() ![]() Usually, one of the first things a program that uses the Java Sound API needs to do is to obtain a mixer, or at least one line of a mixer, so that you can get sound into or out of the computer. It's important not to confuse the Info object with the mixer or line object that it describes. Each of these classes is described further in the appropriate section below. Subclasses of Line.Info includeĭataLine.Info, which obtain details relevant to a specific port and data line, respectively. Line.Info obtains the class of a specific line. Mixer.Info provides details about an installed mixer, such as the mixer's vendor, name, description, and version. Several classes in the Java Sound API provide useful information about associated interfaces. It can also report the file format of a sound file and can write files in different formats. Files and streams - The AudioSystem class provides methods for translating between audio files and audio streams.Format conversions - An application program can use format conversions to translate audio data from one format to another.Lines - Even though every line is associated with a mixer, an application program can get a line directly from the AudioSystem, without dealing explicitly with mixers.The AudioSystem class provides a list of all of the installed mixers. There might also be mixers that don't have I/O ports but instead accept audio from an application program and deliver the mixed audio back to the program. There is usually at least one for audio input and one for audio output. Mixers - A system typically has multiple mixers installed.Here are some of the resources an application program can obtain from the AudioSystem: ![]() From the mixer, the program would then obtain data lines, and so on. For example, an application program might start out by asking the AudioSystem class whether there is a mixer that has a certain configuration, such as one of the input or output configurations illustrated earlier in the discussion of lines. You can query the AudioSystem to learn what sorts of resources have been installed, and then you can obtain access to them. AudioSystem serves as an application program's entry point for accessing these installed sampled-audio resources. Among other things, the resources include mixers and the various types of lines owned by the mixers.ĪudioSystem class acts as a clearinghouse for audio components, including built-in services and separately installed services from third-party providers. The following sections show how your program can learn what sampled-audio resources have been installed on the computer, and how it can gain access to the available resources. Instead, it provides ways for the system to report about the available audio components, and ways for your program to access them. The API makes few assumptions about what devices have been installed and what their capabilities are. Different sorts of audio devices (mixers) can be installed on a computer. Int photocellReading2 = arduino.The Java Sound API takes a flexible approach to system configuration. I get a signal from the 2nd photoresistor but there is still no sound. My status is, that the first one works, but i have problems with the second. Easyer to say.the first file is a song and the second file is an additional beat.Įxcuse me for my bad english, i hope it is understandable x) But what i want to do is, to turn on/off an audiofile - respectivly start it new - with the first photoresistor and to loop an audiofile with another photoresistor, when i point at it with light. First of all, i´m a totaly newbie on arduino and processing, working with them for 2 weeks. I´m working on a project similiar to the project of orange fox. ![]() If(ambient2 = 0) ambient2 = arduino.analogRead(photocellPin2) If(ambient1 = 0) ambient1 = arduino.analogRead(photocellPin1) Int photocellReading2 = arduino.analogRead(photocellPin2) Int photocellReading1 = arduino.analogRead(photocellPin1) Player2 = minim.loadFile("marcus_kellis_theme.mp3", 2048) You'll need to replace the mouseX parts of the if statement with the values you're reading from the arduino.Īrduino = new Arduino(this, Arduino.list(), 57600) I feel like there should be a better solution than this but I've got to get on with something else. The code below works better but has to recue the file from disk every time you restart playback. You can reduce this by decreasing the buffer size but it still gives a glitch. I think the problem is that because the audio samples are buffered, when you do rewind and then play you still get what was left in the buffer from before when you call pause.
