Constructor Detail

AudioCommon

public AudioCommon()

Method Detail

setDebug

public static void setDebug(boolean bDebug)

listSupportedTargetTypes

public static void listSupportedTargetTypes()

TODO:

findTargetType

public static javax.sound.sampled.AudioFileFormat.Type findTargetType(java.lang.String strExtension)

Trying to get an audio file type for the passed extension. This works by examining all available file types. For each type, if the extension this type promisses to handle matches the extension we are trying to find a type for, this type is returned. If no appropriate type is found, null is returned.

listMixersAndExit

public static void listMixersAndExit()

TODO:

listMixersAndExit

public static void listMixersAndExit(boolean bPlayback)

List Mixers. Only Mixers that support either TargetDataLines or SourceDataLines are listed, depending on the value of bPlayback.

getMixerInfo

public static javax.sound.sampled.Mixer.Info getMixerInfo(java.lang.String strMixerName)

TODO: This method tries to return a Mixer.Info whose name matches the passed name. If no matching Mixer.Info is found, null is returned.

getTargetDataLine

public static javax.sound.sampled.TargetDataLine getTargetDataLine(java.lang.String strMixerName,
