Sample rate converter with automatic anti-aliasing filter

The subject disclosure is directed towards dynamically computing anti-aliasing filter coefficients for sample rate conversion in digital audio. In one aspect, for each input-to-output sampling rate ratio (pitch) obtained, anti-aliasing filter coefficients are interpolated based upon the pitch (e.g., using the fractional part of the ratio) from two filters (coefficient sets) selected based upon the pitch (e.g., using the integer part of the ratio). The interpolation provides for fine-grained cutoff frequencies, and by re-computation for each pitch, smooth anti-aliasing with dynamically changing ratios.

Sample rate converter with automatic anti-aliasing filter

The subject disclosure is directed towards dynamically computing anti-aliasing filter coefficients for sample rate conversion in digital audio. In one aspect, for each input-to-output sampling rate ratio (pitch) obtained, anti-aliasing filter coefficients are interpolated based upon the pitch (e.g., using the fractional part of the ratio) from two filters (coefficient sets) selected based upon the pitch (e.g., using the integer part of the ratio). The interpolation provides for fine-grained cutoff frequencies, and by re-computation for each pitch, smooth anti-aliasing with dynamically changing ratios.

Mix buffers and command queues for audio blocks

The subject disclosure is directed towards a technology that may be used in an audio processing environment. Nodes of an audio flow graph are associated with virtual mix buffers. As the flow graph is processed, commands and virtual mix buffer data are provided to audio fixed-function processing blocks. Each virtual mix buffer is mapped to a physical mix buffer, and the associated command is executed with respect to the physical mix buffer. One physical mix buffer mix buffer may be used as an input data buffer for the audio fixed-function processing block, and another physical mix buffer as an output data buffer, for example.
