## Result Status Lifecycle

Each target result progresses through these statuses independently:

<Steps>
  <Step title="pending">Job created; source file not yet uploaded.</Step>
  <Step title="uploaded">Source file received; processing has not started.</Step>
  <Step title="processing">Translation in progress.</Step>
  <Step title="complete">Result is ready to download.</Step>
  <Step title="downloaded">Result has been downloaded; assets marked for deletion.</Step>
</Steps>

A target can transition to `failed` from any non-terminal state. When a target fails, the `error` field contains a description of the failure.

## Limits

| **Limit**                                             |                               **Value** |
| :---------------------------------------------------- | --------------------------------------: |
| Maximum file size                                     |              1 GB (1,073,741,824 bytes) |
| Maximum source duration                               |                                 3 hours |
| Time to upload after job creation                     |                               5 minutes |
| Time to download results after upload                 |                                  1 hour |
| Maximum concurrent jobs per customer                  |                                      10 |
| Maximum concurrent jobs per customer (files > 100 MB) |                                       2 |
| Maximum targets per job                               | No limit (constrained by storage quota) |

After all results are downloaded or the job expires, the job is deleted and returns `404`. Usage is billed based on the duration of the source audio.

Source audio over 3 hours is rejected, even if the file is under 1 GB. For longer recordings, split the source into chunks and submit each as its own job.

## Supported Source Audio Formats

* `audio/mpeg`
* `audio/wav`
* `audio/ogg`
* `audio/flac`
* `audio/mp4`
* `audio/webm`

## Supported Languages

Source and target languages match the [real-time Voice API](/api-reference/voice#supported-languages). `source_language` is optional; if omitted, the language is detected automatically.

## Supported Output Formats

Each target specifies a `type` for the desired output format.

| **Type**                                       | **Description**                           |
