curl -X POST "https://api.eu.apyhub.com/freedailypro/convert-audio-format-api/audio-convert" \
  -H "apy-token: $APY_TOKEN" \

## About

## What it does
Audio Converter converts one audio file into another format. Send a binary file and choose a target format, then get the converted file back as binary output.

Use it when you need to normalize uploads, prepare media for a specific player, or fit audio into a downstream workflow that only accepts certain formats. The service accepts files up to 30 MB and supports mp3, wav, ogg, m4a, and flac as input formats.

Because the response is the converted file itself, it fits cleanly into storage pipelines, content ingestion jobs, and internal tooling that needs format conversion without extra parsing. If you are building an app that receives user audio and needs to standardize it before processing, Audio Converter keeps that step simple.

It is a good match for batch jobs, upload handlers, and media automation where the only thing you need is a reliable format change.
