Parameters:
| Name |
Type |
Description |
sample |
Number
|
The sample to add |
- Source:
-
addSampleToAllChannels(sample)
-
Add a sample to all the channels in the wave data
(e.g. if you want the left and right channel in a stereo
file to be the same).
Parameters:
| Name |

sample |
Number
|
The sample to add |
- Source:
-
create(channelCount, sampleRate, bitsPerSample)
-
Construct a new wav file instance. This creates a PCM encoded wave
file (so isuncompressed).
Parameters:
| Name |
Type |
Description |
channelCount |
Number
|
The number of channels (1 = mono, 2 =
stereo, etc) |
sampleRate |
Number
|
The sample rate (8000, 44100, etc) |
bitsPerSample |
Number
|
The number of bits per sample - see
WaveFile.SampleSize |

-
getSampleCountInOneChannel()
-
Gets the sample count in a single channel.
- Source:
Returns:
The number of samples in a single channel.
-
getSampleSize()
-
Gets the number of bits per sample in the wave data.

getTotalSampleCount()
-
Gets the total number of samples in the data.
- Source:
Returns:
The total number of samples in the data (if there are
multiple channels this may not be what you expect - see
getSampleCountInOneChannel).
