rubato-resample

To resample audio streams in Rust, use rubato's SincFixedIn or SincFixedOut types within a real-time processing loop, ensuring proper input framing and channel handling for chunked streaming pipelines. This approach balances configurable quality and latency effectively.

You need to normalize microphone input to 16 kHz for ASR in Rust when your source audio is recorded at higher sample rates like 44.1 kHz or 48 kHz, requiring resampling to match the expected input format of speech recognition models.

The best way to handle multi-channel audio resampling in Rust is to apply optional stereo-to-mono downmixing before resampling, then configure rubato's resamplers to process the resulting channels across common audio sampling rates.

Yes, you can use rubato for streaming pipelines by configuring the resampler with proper per-call input_frames_next sizing, allowing it to process chunked audio input efficiently in real-time without dropping frames.

Rubato's SincFixedIn and FastFixedIn differ in quality and latency trade-offs; SincFixedIn uses SincInterpolationParameters for higher quality resampling, whereas FastFixedIn prioritizes lower latency for real-time audio streams.
