v11.0.0

version 11.0.0 - 2020-01-30

API changes

• clamp int samples on overflow instead of throwing RangeError

Other changes

• Zero dependencies

v10.4.3

version 10.4.3 - 2020-01-27

• Fix: large files RIFF/RIFX conversion

v10.4.2

version 10.4.2 - 2020-01-22

Better sinc resampling.

v10.4.1

version 10.4.1 - 2020-01-21

Faster sinc resampling.

v10.4.0

version 10.4.0 - 2020-01-20

• Default LPF for resample is IIR
• Use FIR or IIR LPFs to resample:

// Will use 'linear' method with a FIR LPF
wav.toSampleRate(44100, {method: "linear", LPF: true, LPFType: 'FIR'});

// Will use 'linear' method with a IIR LPF, the default
wav.toSampleRate(44100, {method: "linear", LPF: true});

v10.3.0

version 10.3.0 - 2020-01-20

Features

• New resample methods: linear for linear interpolation and point for nearest point interpolation. Both methods use no LPF by default; others methods use LPF by default.

• Resample with or without LPF using any interpolation method:

// Resample using cubic without LPF
wav.toSampleRate(44100, {method: 'cubic', LPF: false});
// Resample using cubic with LPF:
wav.toSampleRate(44100, {method: 'cubic', LPF: true});
// cubic and sinc use LPF by default
wav.toSampleRate(44100, {method: 'cubic'}); // will use LPF

• You can now use any Typed Array as the output for getSamples():

// Will return the samples de-interleaved,
// packed in a array of Int32Array objects, one for each channel
samples = wav.getSamples(false, Int32Array);
// will return the samples de-interleaved,
// packed in a array of Int16Array objects, one for each channel
let samples = getSamples(false, Int16Array);
// will return the samples interleaved, packed in a Int16Array
let samples = getSamples(true, Int16Array);

v10.2.0

version 10.2.0 - 2020-01-16

Change the sample rate.

New Features:

Change the sample rate with wav.toSampleRate();

Fixes:

• Bug that prevented creating multi channel files using a array of typed arrays for samples
• Type declaration for sample arrays now use more generic types to ease integration

v10.1.0

Add getSamples() to the API. It returns the samples packed in a Float64Array.
If the file have more than one channel, samples will be returned de-interleaved
in a Array of Float64Array objects, one for each channel. The method takes a
optional boolean param interleaved, set to false by default. If set to
true, samples will be returned interleaved. Default is de-interleaved.

// Both will return de-interleaved samples
samples = wav.getSamples();
samples = wav.getSamples(false);

// To get interleaved samples
samples = wav.getSamples(true);

v10.0.0

version 10.0.0 - 2020-01-07

Better handling of cue points and regions.

API Changes:

• listCuePoints() now returns a list of objects with more information about each cue point:

[
	{
		position: 500, // the position in milliseconds
		label: 'cue marker 1',
		end: 1500, // the end position in milliseconds
		dwName: 1,
		dwPosition: 0,
		fccChunk: 'data',
		dwChunkStart: 0,
		dwBlockStart: 0,
		dwSampleOffset: 22050, // the position as a sample offset
		dwSampleLength: 3646827, // the region length as a sample count
		dwPurposeID: 544106354,
		dwCountry: 0,
		dwLanguage: 0,
		dwDialect: 0,
		dwCodePage: 0,
	},
	//...
];

• setCuePoint() param is now a object with the cue point data:

// to create a cue point the position in milliseconds
// is the only required attribute
wav.setCuePoint({position: 1500});

// to create a cue point with a label
wav.setCuePoint({position: 1500, label: 'some label'});

// to create a cue region with a label:
wav.setCuePoint({position: 1500, end: 2500, label: 'some label'});

Objects that define regions can also define the following optional properties:

• dwPurposeID
• dwCountry
• dwLanguage
• dwDialect
• dwCodePage

New Features:

• setCuePoint() now can create both cue points and regions.

Fixes:

• Fix setCuePoint() bug that caused some labels to display the wrong text

v9.1.1

• Smaller dist file
