AudioInterface(PlayerClient pc,
short indexOfDevice)
Constructor for AudioInterface. |
Method Summary | |
---|---|
int[] |
getFiveHighestAmplitudes()
Returns the five highest amplitudes. |
int[] |
getFiveHighestFrequencies()
Returns the five highest frequencies. |
void |
produceSound(short freq,
short amp,
short duration)
The audio interface accepts commands to produce fixed-frequency tones through /dev/dsp (which is assumed to be associated with a sound card to which a speaker is attached). |
void |
readData()
The audio interface reads the audio stream from /dev/audio (which is assumed to be associated with a sound card connected to a microphone) and performs some analysis on it. |
