## How credits are calculated

Credits are charged **per minute of source audio, per target model**. Duration is always rounded up to the nearest minute. See the [Models](https://developer.audioshake.ai/models) page for per-model credit rates.

## Examples

**A 3-minute song with 2 targets at 1.0 credit/min each:**

> 3 min x 2 targets x 1.0 = **6 credits**

**A 45-second clip with 1 target at 1.5 credits/min:**

> 1 min (rounded up) x 1 target x 1.5 = **1.5 credits**

**A 10-minute podcast with dialogue + music_fx at 1.5 credits/min each:**

> 10 min x 2 targets x 1.5 = **30 credits**
