samplerateconversion
Samplerateconversion is the process of converting a discrete-time signal from one sampling rate to another. It is common in audio, multimedia, and communications to enable mixing sources with different rates, standardize to a target rate, or match hardware constraints. The operation aims to preserve spectral content within the new bandwidth while minimizing aliasing and distortion.
The standard approach involves upsampling by a factor L (inserting L−1 zeros between samples) and applying a
Time-domain methods include zero-order hold, linear or higher-order interpolation, and spline approaches. These are simple and
Key considerations include anti-aliasing, imaging suppression, phase accuracy, latency, and numerical precision. The preferred method balances
Samplerate conversion is essential in audio production, streaming, and digital communications to ensure compatibility between devices
