SourceFileMediaFoundation /

Returns an copy of this Source with all properties identical except the sampleRate. This is useful if the SourceFile must match a samplerate that was unknown when it was first constructed.

Returns the number of channels.

Returns the true samplerate of the Source .

Actual output samplerate may differ.

Implement to perform read of frames into buffer starting at offset bufferFrameOffset

the actual number of frames read.

Implement to perform seek. readPositionFrames is in native file units.

Loads either as many frames as buffer can hold, or as many as there are left.

number of frames read into buffer .

Returns a copy of this Source , with identical properties and pointing at the same data source.

Loads and returns the entire contents of this SourceFile .

a BufferRef containing the file contents.

Seek the read position to readPositionFrames .

Seek to read position readPositionSeconds .

Returns the current read position in frames.

Returns the current read position in seconds.

Returns the length in frames.

Returns the length in seconds.

Returns the user facing samplerate (output).

Returns the maximum number of frames that can be read with one call to read() .

Sets the maximum number of frames that can be read in one chunk.

Returns the metadata, if any, as a string.

Creates a new SourceFile from dataSource , with optional output samplerate. If sampleRate equals 0 the native file's samplerate is used.

Sets up samplerate conversion if needed. Can be overridden by implementation if they handle samplerate conversion in a specific way, else it is handled generically with a dsp::Converter .

Implementations should override and return true if they can provide samplerate conversion. If false (default), a Converter will be used if needed.

Allows implementations to set the output samplerate.
