Business and Enterprise customers can now choose from multiple sample rates for more control over quality, performance, and file size - optimized for your needs.
What is a Sample Rate?
Sample rate determines how often sound is measured per second during clip rendering or playback. Higher sample rates mean better audio quality, but also larger file sizes.
Here’s a quick breakdown:
| Sample Rate | Best For | File Size | Audio Quality |
| 24 kHz - Lightweight and efficient for low-bandwidth use. | Voice notes, support tools, basic TTS | Small | Good |
| 48 kHz - Balanced and standard for most media and platforms. | Video playback, web apps, production workflows | Medium | Excellent |
| 96 kHz - Highest-quality output for professional-grade audio. | High-end production, audio voiceovers, archives | Large | Exceptional |
How to Create Audio with Different Sample Rates
- Choose a Voice that supports variable sample rates by checking the box in the Voice filter sidebar in Studio.
- Generate your audio clip at the preferred sample rate by clicking the Sample Rate dropdown and selecting 24, 48, or 96 kHz.
- Click the Create button to generate your audio clip. The clip can be downloaded using the sample rate selected.
⚠️ If a Voice doesn’t support different sample rates, the dropdown will appear disabled.
Not sure which sample rate to use? Check out our tips on choosing the right one for your project:
- Use 48 kHz for most content—a solid balance of quality and file size.
- Go with 24 kHz when speed and efficiency matter most.
- 96 kHz when only pristine, high-grade audio will do.
Note: While you can download a clip using a 96 kHz sample rate using any file type, file compression will impact the 96 kHz quality. To preserve the high quality of your 96 kHz clips, download as .WAV files.
