AudioBuffer

An AudioBuffer is a multi-channel buffer, with defined length, to act as storage of audio samples of type T. It is passed around by DSP algorithms. Data is store deinterleaved.

Functions

alignment int alignment(): Return alignment of the sample storage.
assumeIsolated void assumeIsolated(): Undocumented in source. Be warned that the author may not have intended to support it.
channels int channels(): Return number of channels in this buffer.
chunkBy auto chunkBy(int maxFrames): Return an input range that returns several subbuffers that covers the parent buffer, each with length not larger than maxFrames.
copyFrom void copyFrom(const(AudioBuffer) source): Copy samples from source to dest. Number of frames and channels must match.
fillWithValue void fillWithValue(T value): Fill the buffer with a single value. Warning: the buffer must be in fp32 format.
fillWithZeroes void fillWithZeroes(): Fill the buffer with zeroes.
frames int frames(): Return number of frames in this buffer.
getChannel T[] getChannel(int channel)
const(T)[] getChannel(int channel)
immutable(T)[] getChannel(int channel): Get slice of a given channel.
getChannelPointer T* getChannelPointer(int channel): Get pointer of a given channel.
getChannelPointer const(T)* getChannelPointer(int channel): Get const pointer of a given channel.
getChannelPointer immutable(T)* getChannelPointer(int channel): Get immutable pointer of a given channel.
getChannelsPointers
T** getChannelsPointers(): Get channel pointers.
getChannelsPointers const(T*)* getChannelsPointers(): Get const channel pointers.
getChannelsPointers immutable(T*)* getChannelsPointers(): Get immutable channel pointers.
hasOwnership bool hasOwnership()
initWithData
void initWithData(int channels, int frames, T** inData): Dispose the previous content, if any. Allocate a new AudioBuffer with given frames and channels. This step can reuse an existing owned allocation.
isIsolated bool isIsolated()
isSilent bool isSilent()
opDollar int opDollar(): Undocumented in source. Be warned that the author may not have intended to support it.
opDollar int opDollar(): Undocumented in source. Be warned that the author may not have intended to support it.
opIndex inout(T)[] opIndex(int channel): Get slice of a given channel.
opIndex AudioBuffer opIndex()
const(AudioBuffer) opIndex(): Create an AudioBuffer that is a ref to the same data.
opIndex inout(T) opIndex(int channel, int frame): Index a single sample.
opIndex AudioBuffer opIndex(int[2] chan)
const(AudioBuffer) opIndex(int[2] chan): Slice with a sub-range of channels.
opIndex AudioBuffer opIndex(int[2] chan, int[2] framesBounds)
const(AudioBuffer) opIndex(int[2] chan, int[2] framesBounds): Slice across channels and temporally. Take a sub-range of channels, and a sub-range of frames.
opSlice int[2] opSlice(int start, int end): Select only a slice of channels from AudioBuffer.
recomputeZeroFlag void recomputeZeroFlag(): Recompute the status of the zero flag. Otherwise, asking for a mutable pointer into the zero data will clear this flag. This is useful if you've written in a buffer and want to optimize downstream.
resize void resize(int channels, int frames, int alignment): Change the size (channels and frames of the underlying store. Data is left uninitialized. Typically you would reuse an AudioBuffer if you want to reuse the allocation. When the same size is requested, the same allocation is reused (unless alignment is changed).
sliceChannels AudioBuffer sliceChannels(int channelStart, int channelEnd): Select only a slice of channels from AudioBuffer.
sliceChannels const(AudioBuffer) sliceChannels(int channelStart, int channelEnd): Undocumented in source. Be warned that the author may not have intended to support it.
sliceFrames AudioBuffer sliceFrames(int frameStart, int frameEnd)
const(AudioBuffer) sliceFrames(int frameStart, int frameEnd): Create a AudioBuffer derivated from another buffer.
