| Description |
This class allows you low-level access to an audio buffer to create, access, manipulate and play back sound samples.
If you want to pre-load your audio sample with an audio file from disk you can do so using the SoundFile subclass.
|
| Methods |
| channels() |
Returns the number of channels in the audiosample. |
| cue() |
Cues the playhead to a fixed position in the audiosample. |
| duration() |
Returns the duration of the audiosample in seconds. |
| frames() |
Returns the number of frames of the audiosample. |
| jump() |
Jump to a specific position in the audiosample while continuing to play. |
| play() |
Starts the playback of the audiosample. Only plays to the end of the
audiosample once. |
| rate() |
Set the playback rate of the audiosample. |
| resize() |
Resizes the underlying buffer of the audiosample to the given number of
frames. |
| sampleRate() |
Returns the underlying sample rate of the audiosample. |
| pan() |
Move the sound in a stereo panorama. Only works for mono audiosamples! |
| isPlaying() |
Check whether this audiosample is currently playing. |
| pause() |
Stop the playback of the sample, but cue it to the current position. |
| read() |
Read some frames of this audio sample into an array. |
| write() |
Write some frames of this audio sample. |

| Parameters |
| parent |
PApplet: typically use "this" |
| frames |
int: the desired number of frames for this audiosample |
| stereo |
boolean: whether to treat the audiosample as 2-channel (stereo) or not
(default: false) |
| frameRate |
int: the underlying frame rate of the sample (default: 44100) |
| data |
float[]: an array of float values to be used as this audiosample's sound
data. The audiosample will consequently have as many frames as the
length of the given array. |
