template<typename SampleFormat, typename Endianness, typename InterleavingType, typename Constness>
class AudioData::Pointer< SampleFormat, Endianness, InterleavingType, Constness >
Used as a template parameter for AudioData::Pointer.
Indicates that the samples can only be used for const data.. A pointer to a block of audio data with a particular encoding.
This object can be used to read and write from blocks of encoded audio samples. To create one, you specify the audio format as a series of template parameters, e.g.
AudioData::LittleEndian,
AudioData::NonInterleaved,
AudioData::Const> pointer (someRawAudioData);
float firstSampleAsFloat = pointer.getAsFloat();
int32 firstSampleAsInt = pointer.getAsInt32();
++pointer;
pointer += 3;
Used as a template parameter for AudioData::Pointer.

signed int int32
A platform-independent 32-bit signed integer type.
Definition juce_MathsFunctions.h:58
The convertSamples() method lets you copy a range of samples from one format to another, automatically converting its format.

typename Constness::VoidType * | sourceData | ) |

|
noexcept |
Creates a non-interleaved pointer from some raw data in the appropriate format.
This constructor is only used if you've specified the AudioData::NonInterleaved option - for interleaved formats, use the constructor that also takes a number of channels.

|
|
noexcept |
Sets the value of the first sample as a floating point value.
(This method can only be used if the AudioData::NonConst option was used). The value should be in the range -1.0 to 1.0 - for integer formats, values outside that range will be clipped. For floating point formats, any value passed in here will be written directly, although -1 to 1 is the standard range.
template<typename SampleFormat , typename Endianness , typename InterleavingType , typename Constness >
Returns the value of the first sample as a 32-bit integer.
The value returned will be in the range 0x80000000 to 0x7fffffff, and shorter values will be shifted to fill this range (e.g. if you're reading from 24-bit data, the values will be shifted up by 8 bits when returned here). If the source data is floating point, values beyond -1.0 to 1.0 will be clipped so that -1.0 maps onto -0x7fffffff and 1.0 maps to 0x7fffffff.

staticnoexcept |
Returns the accuracy of this format when represented as a 32-bit integer.
This is the smallest number above 0 that can be represented in the sample format, converted to a 32-bit range. E,g. if the format is 8-bit, its resolution is 0x01000000; if the format is 24-bit, its resolution is 0x100.
