Aloe-Oboe Flowgraph Resampler

The aloe-oboe-flowgraph-resampler crate offers a comprehensive suite of tools for multi-channel audio resampling. Its primary focus is on optimizing audio processing pipelines by utilizing sophisticated resampling techniques, including multi-channel resamplers and advanced windowing functions.

Features

• MultiChannelResampler: Core of the crate, facilitating adjustable quality and performance through MultiChannelResamplerQuality enum settings.
• High-Performance Resampler Implementations: Includes types like PolyphaseResampler, SincResampler, and LinearResampler, each supporting varying computational efficiency and quality ratios.
• Advanced Window Functions: Incorporates ResamplerKaiserWindow and HyperbolicCosineWindow for precise filter design with tunable characteristics.
• Flowgraph Support: FlowgraphRampLinear provides seamless transition management of control values, minimizing audio artifacts during parameter changes.

Usage

To employ resampling, instantiate a resampler builder such as MultiChannelSamplerBuilder, configure its properties (e.g., input/output rates), and build the desired resampler type. For example:

let mut builder = MultiChannelSamplerBuilder::default();
builder.set_input_rate(48000)
       .set_output_rate(44100)
       .set_num_taps(16)
       .set_channel_count(2);

let resampler = builder.build();

Technical Insights

The crate centers around precise control of audio sample phase, leveraging integer ratios of input/output rates for performance gains. It precomputes coefficients for optimal efficiency during frame processing, reducing computational overhead associated with frequently changing ratios.
