Audio Hz Converter

This tool converts any supported audio source to a fixed 44100 Hz sample rate. It accepts a source_rate_hz and optional channel_count and bit_depth metadata; if an audio file is supplied, the tool can read its rate and resample accordingly. The output is a new audio stream at 44100 Hz along with accompanying metadata that documents the transformation.
Conceptually, resampling maps input samples to the target rate using a band-limited interpolation filter to minimize artifacts. If the source rate already equals 44100 Hz, the tool yields a pass-through result for that segment with no change to audio content. The algorithm emphasizes preserving spectral integrity while avoiding aliasing, making it suitable for music, podcasts, game assets, and archival material.
Benefit-wise, audio engineers, game developers, researchers, and media producers gain a predictable, tool-assisted workflow that reduces manual DSP steps, ensures compatibility with standard playback pipelines, and simplifies asset management. The tool's core features include rate validation, optional channel/bit-depth adjustments, and a clear resampling path to 44100 Hz. Use cases include archival material modernization, asset standardization for engines, and cross-platform distribution.
