## Class Documentation

## ◆ juce::AudioData::Format

struct juce::AudioData::Format

template<typename DataFormatIn, typename EndiannessIn>
struct juce::AudioData::Format< DataFormatIn, EndiannessIn >

A struct that contains a SampleFormat and Endianness to be used with the source and destination types when calling the interleaveSamples() and deinterleaveSamples() helpers.

## Member Typedef Documentation

## ◆ InterleavedDest

template<typename... Format>

using juce::AudioData::InterleavedDest = ChannelData<true, false, Format...>

A sequence of interleaved samples used as the destination for the interleaveSamples() method.

Definition at line 699 of file juce_AudioDataConverters.h.

## ◆ InterleavedSource

template<typename... Format>

using juce::AudioData::InterleavedSource = ChannelData<true, true, Format...>

A sequence of interleaved samples used as the source for the deinterleaveSamples() method.

Definition at line 697 of file juce_AudioDataConverters.h.

## ◆ NonInterleavedDest

template<typename... Format>

using juce::AudioData::NonInterleavedDest = ChannelData<false, false, Format...>

A sequence of non-interleaved samples used as the destination for the deinterleaveSamples() method.

Definition at line 703 of file juce_AudioDataConverters.h.

## ◆ NonInterleavedSource

template<typename... Format>

using juce::AudioData::NonInterleavedSource = ChannelData<false, true, Format...>

A sequence of non-interleaved samples used as the source for the interleaveSamples() method.

Definition at line 701 of file juce_AudioDataConverters.h.

## Member Function Documentation

## ◆ deinterleaveSamples()

template<typename... SourceFormat, typename... DestFormat>

static void juce::AudioData::deinterleaveSamples | ( | InterleavedSource< SourceFormat... > | source,
|  | NonInterleavedDest< DestFormat... > | dest,
|  | int | numSamples )
| inlinestatic

A helper function for converting a sequence of samples from an interleaved source to a non-interleaved destination.

When calling this method you need to specify the source and destination data format and endianness from the AudioData SampleFormat and Endianness types and provide the data and number of channels for each. For example, to convert a floating-point stream of big endian samples to an non-interleaved, native endian stream of 16-bit integer samples you would do the following:

using SourceFormat = AudioData::Format<AudioData::Float32, AudioData::BigEndian>;
using DestFormat = AudioData::Format<AudioData::Int16, AudioData::NativeEndian>;
AudioData::deinterleaveSamples (AudioData::InterleavedSource<SourceFormat> { sourceData, numSourceChannels },
AudioData::NonInterleavedDest<DestFormat> { destData, numDestChannels },
numSamples);

## ◆ interleaveSamples()

template<typename... SourceFormat, typename... DestFormat>

static void juce::AudioData::interleaveSamples | ( | NonInterleavedSource< SourceFormat... > | source,
|  | InterleavedDest< DestFormat... > | dest,
|  | int | numSamples )
| inlinestatic

A helper function for converting a sequence of samples from a non-interleaved source to an interleaved destination.

When calling this method you need to specify the source and destination data format and endianness from the AudioData SampleFormat and Endianness types and provide the data and number of channels for each. For example, to convert a floating-point stream of big endian samples to an interleaved, native endian stream of 16-bit integer samples you would do the following:

using SourceFormat = AudioData::Format<AudioData::Float32, AudioData::BigEndian>;
using DestFormat = AudioData::Format<AudioData::Int16, AudioData::NativeEndian>;
AudioData::interleaveSamples (AudioData::NonInterleavedSource<SourceFormat> { sourceData, numSourceChannels },
AudioData::InterleavedDest<DestFormat> { destData, numDestChannels },
numSamples);
