void |
spectrumDataUpdate(double timestamp,
double duration,
float[] magnitudes,
float[] phases)
Notifies the observer about new data available for the audio spectrum.
|
void spectrumDataUpdate(double timestamp, double duration, float[] magnitudes, float[] phases)
The notification period for updates may be set using
MediaPlayer.setAudioSpectrumInterval(double)
, and the number of bands and
sensitivity threshold via MediaPlayer.setAudioSpectrumNumBands(int)
and
MediaPlayer.setAudioSpectrumThreshold(int)
, respectively. The default
values of the settings are an interval of 0.1
seconds,
128
bands, and sensitivity threshold -60.0
dB.
The arrays passed to the listener should be considered to be read-only as the underlying implementation may re-use them.
timestamp
- timestamp of the event in seconds.duration
- duration for which the spectrum was computed in seconds.magnitudes
- array containing the non-positive spectrum magnitude in decibels
(dB) for each band.
The size of the array equals the number of bands and should be considered
to be read-only.phases
- array containing the phase in the range
[Math.PI
, Math.PI
] for each band.
The size of the array equals the number of bands and should be considered
to be read-only.Copyright (c) 2008, 2014, Oracle and/or its affiliates. All rights reserved.
