## Overview Audio to Audio Conv by Wiro converts existing audio into a new audio format. You upload one or more files, pick an output codec/container, and it exports new audio files. It’s built for clean delivery formats. Use it to standardize inputs across tools, reduce file size with compression, or produce lossless WAV/FLAC masters. ## What you can build - A podcast ingestion step that normalizes uploads into MP3 for distribution. - A “download as WAV/FLAC” feature for creators who need lossless audio. - A batch conversion tool for migrating a library to a single format. - A workflow step that converts mixed user uploads into an editing-friendly format. - A mobile backend that exports Opus or AAC for efficient streaming. ## Inputs - One to ten audio files to convert. Each file is processed independently and returned separately. - Audio files can be provided as uploads or as direct file URLs. - A required target output format. Supported formats include MP3, WAV, M4A, AAC, FLAC, OGG, and Opus. - An optional bitrate setting for compressed formats. Choose a value between 32 and 320 kbps. ## Outputs - A separate output audio file for each input file. - Each output includes a downloadable file entry with a filename, a MIME content type, a byte size, and a CDN URL. - The output file container matches the selected format (for example, MP3 or WAV). ## Limitations - You can convert up to 10 files per run. - The bitrate control only applies to compressed formats. It doesn’t change WAV or FLAC exports. - Very low bitrates can add audible artifacts. Speech may sound warbly. - Lossless outputs (WAV, FLAC) produce larger files than compressed formats. - Low-quality or problematic inputs can degrade results. Examples include clipped audio, heavy background noise, or corrupted files. - Scanned “audio inside video” inputs aren’t supported here. Provide an actual audio file. - File handling depends on platform limits. Single uploaded files have a 100 MB limit. ## Safety & compliance - Only convert audio you own or have rights to use. - Don’t use this tool to redistribute copyrighted content without permission. - Output file URLs are publicly accessible to anyone with the link. Download and store outputs securely if they contain sensitive audio.
