# VOICE_MEMO_UNREADABLE

> Voice memo can't be processed

| HTTP status | Retryable |
| - | - |
| `400` | No |

## What happened

Blujay stores every voice memo as M4A so it plays on iPhone and in every browser. The audio file for this `audio` part is not M4A and could not be read to convert it, for example because it is damaged or empty.

## How to fix it

Record the voice memo again, or send an M4A (AAC) file, which is used as is. Retrying the same file returns the same error.

## Example response

An illustrative example. The `message` wording and the contents of `details` vary; branch on `error.code`.

```json theme={null}
{
  "status": "error",
  "error": {
    "code": "VOICE_MEMO_UNREADABLE",
    "message": "Voice memo can't be processed",
    "type": "validation",
    "http_status": 400,
    "retryable": false,
    "doc_url": "https://docs.blujay.io/errors/voice-memo-unreadable",
    "details": []
  },
  "trace_id": "trc_8f2a1c0e4b7d",
  "timestamp": "2026-10-14T17:30:48.000Z"
}
```

## Still stuck?
