public interface AudioBuffer
AudioBuffer
is specifically a buffer of floating point samples
corresponding to a single channel of streaming audio. It is readonly, but you
can obtain a copy of the samples in the buffer by using toArray()
. In
fact, when drawing a waveform, you should use toArray
rather than
iterating over the buffer itself. This is because it is possible that the samples
in the buffer will be replaced with new ones between calls to get(int)
,
which results in a waveform that appears to have discontinuities in it.Modifier and Type | Method and Description |
---|---|
float |
get(int i)
Gets the
ith sample in the buffer. |
float |
level()
Gets the current level of the buffer.
|
int |
size()
Returns the length of the buffer.
|
float[] |
toArray()
Returns the samples in the buffer in a new float array.

int size()

ith

does not do bounds checking, so it may throw an exception.i
