AWB Audio Converter

AWB Audio Converter provides a focused, format-agnostic pipeline for converting audio files between common formats while preserving essential data. Target users include editors, podcasters, musicians, and content producers who distribute assets to multiple platforms and devices. It addresses needs for consistent compatibility, predictable encoding quality, and metadata integrity across output formats. Core Logic & Features: This tool implements a decode-then-encode pipeline with support for input formats (MP3, WAV, AAC, FLAC, OGG, M4A) and user-selected output formats. Required features: file intake, target format, and encoding settings; optional/advanced features: bitrate, sample rate, channels, loudness normalization, metadata editing, batch processing. Inputs & Outputs: Inputs include input_file (binary), input_format (string), target_format (string), bitrate (integer kbps, optional), sample_rate (integer Hz, optional), channels (1 or 2, optional), metadata fields (title/artist/album, optional). Outputs include output_file (binary), actual_format (string), duration (seconds), size (bytes), metadata_saved (boolean). Algorithms & Calculations: Encoding uses standard codecs with a decode-encode pipeline; sample-rate conversion via high-quality resampling; bitrate control via CBR or VBR settings; metadata preservation and optional normalization are applied; error handling relies on validation checks. Error & Edge Cases: Unrecognized input format triggers an input error; missing file triggers a validation error; invalid bitrate or sample_rate results in a parameter error; extremely large files may trigger batch limits; corrupted streams produce decode errors. Industry/Region & Localization: Supports common standards (ID3v2, Vorbis comments) and units in kbps, Hz, and samples; locale-aware metadata handling; language set to English by default. Assumptions & Exclusions: Assumes local file access or remote upload; does not transcode video or apply complex audio effects; no DRM; batch uploads are subject to size limits.
