AMR to MP3 Converter

This tool converts AMR audio to MP3 for broad compatibility across players and platforms. It accepts AMR inputs, decodes to PCM, and encodes to MP3 using user-specified bitrate, sample rate, and channel settings. It is suitable for podcasters, archival staff, and developers who integrate audio processing into pipelines. Outputs are determined by the chosen bitrate and sample rate, with generic defaults that balance quality and file size.
Conceptually, the workflow is a two-stage process: decode AMR to PCM, then encode to MP3 with the selected parameters. If input sample rate differs from the target, the tool resamples to the requested rate and adjusts channels as needed. Batch processing queues multiple files and processes them in parallel, returning per-file results and a consolidated report.
This tool provides a practical balance between speed, quality, and usability. It preserves basic metadata when compatible, and the resulting MP3s are widely playable in consumer devices and editing software. The design targets workflows in content creation, transcription, and archival tasks, offering predictable presets and a straightforward API in development contexts.
