Advanced tools
Create AudioBuffer from any source.
var createBuffer = require('audio-buffer-from')
//mono-buffer 1024 samples
var abuf = createBuffer(1024)
//stereo-buffer 1024 samples
var abuf2 = createBuffer(1024, 2)
//buffer from data with bound audio context
var abuf3 = createBuffer(floatArray, {context: audioContext})
//empty 1-sample mono buffer with default context
var abuf4 = createBuffer()
//0-length no-context buffer
var abuf5 = createBuffer(0)
//from duration
var abuf6 = createBuffer({duration: 1})
//from pcm data
var abuf7 = createBuffer(new Uint8Array([0, 0, 255, 255]), 'interleaved 96000')
//from data-uri
var abuf8 = createBuffer('data:application/octet-stream;base64,AP8A/w==', 'uint8')
//from base64 string
var abuf9 = createBuffer('AAAAAAAAAAAAAIA/AACAPw==', 'float32 stereo planar')
//from node Buffer
var abuf10 = createBuffer(Buffer.from([0, 255, 0, 127]), 'interleaved')
Create audio buffer from any source
data or a number indicating length
, pass options
to ensure output buffer parameters. A channels
number or format
string can be used to shorthand options argument.
Type | Interpretation |
---|---|
null | Blank 1-sample length buffer. |
Number | Length of resulting buffer. |
Array of Arrays | Every subarray is considered a channel data. |
AudioBuffer | Clone other AudioBuffer. |
AudioBufferList | Coalesce AudioBufferList to AudioBuffer. |
Audio | Retrieve AudioBuffer from Audio. |
Object | Create based on length /duration , channels /numberOfChannels and sampleRate properties. |
Array of Numbers | Raw data, interpreted by options.format , defaults to float64 . |
Float32Array | Raw float32 data, amplitude range is -1..+1 . |
Float64Array | Raw float64 data, amplitude range is -1..+1 . |
Int8Array | Raw int8 data, amplitude range is -128..+127 . |
Uint8Array | Raw uint8 data, amplitude range is 0..255 . |
TypedArray | Any other typed array, described by options.format argument (see pcm-convert). |
ArrayBuffer | Raw data, interpreted by options.format . |
Buffer | Raw data, interpreted by options.format . |
base64 string | Base64-encoded data. |
dataURI string | DataURI string. |
ndarray | Create from ndarray instance. The shape property is considered as [length, channels] . |
ndsamples | Create from ndsamples instance, similar to ndarray. |
Property | Default | Meaning |
---|---|---|
length | 1 | Buffer length. If 0 , buffer is unbound from context. |
context | audio-context | Audio context to bind. null -context creates context-free audio buffer. |
channels , numberOfChannels | 1 | Buffer number of channels. |
sampleRate , rate | 44100 | Buffer sample rate. |
format | null | Source pcm format string or object, see audio-format. If null , it will be detected from the source . |
