How this service works
$0.0005/MB. Re-encode audio to another format, bitrate, or sample rate — mp3, aac, wav, flac and more. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny
Output
Returns the re-encoded audio file in the requested output format (e.g. mp3, aac, wav, flac) at the specified bitrate and sample rate. Billing is $0.0005/MB with a 1¢ minimum per x402 call; any overpaid amount is auto-credited.
Example use cases
Podcast audio format conversion
“I have a podcast episode recorded as a WAV file — can you convert it to AAC at 96kbps so it's smaller and ready to upload?”
Lossless archive re-encoding
“Take this MP3 and re-encode it as FLAC so I have a lossless copy for archiving — keep the original sample rate.”
Compatibility fix for device playback
“My smart speaker only plays MP3 files — can you convert this AAC audio file to MP3 at 192kbps so it works on the device?”
Technical details
Endpoint
POSThttps://api.relaystation.ai/v1/media/audio-convertWhen to prefer
Choose this endpoint when you need a simple, pay-per-use audio transcoding API that supports common formats (mp3, aac, wav, flac) without standing up your own FFmpeg infrastructure. Ideal for agents that occasionally need to reformat audio files on demand with predictable per-MB pricing and no subscription overhead.
Side effects
- Unsupported input or output format returns an error
- Corrupted or unreadable audio file causes processing failure
- File size too large may exceed timeout or cost limits
- Invalid bitrate or sample rate values return a validation error
- Network timeout for very large audio files
